If anyone is curious supercharged Diesel's did exist from the factory but they're stupid rare. ( If you disregard Detroit Diesel, although those blowers don't add boost to the engine it's just so that they can run. That's a whole different thing lol ) As far as I know I'm pretty sure Cummins is really the only one to do it there might be a European brand that did but I'm not sure. But look up the C-130 Cummins and the NHS-275. Both of those came stock from the factory with superchargers. Really cool engines and like I said really really rare. We're talking 1940s-1960s forgotten technology
@@mmllmmll22 oh yeah for sure I kind of mentioned that in my little tidbit but that's why I didn't go into Detroit's. It operates in functions significantly different than a four-stroke motor
The Turbo is a lot quieter doing what it does. I also would like to see a more real world pulling up a less steep slope but for a longer distance and seeing what heat, etc happens. On a hill like that, putting that much torque through probably would have broken something in the drivetrain or at least damaged it.
@@bennyboyy7 Turbos have some issues on petrol engines that they dont have on diesel engine: Petrol engines have much higher exhaust temperatures, meaning that turbo cooling is a challenge, for example there are very few VTG petrol turbos while most production turbo diesels use it. - Petrol engines always run throttled, meaning that load changes make you waste all that glorious boost for nothing. Diesel doesnt reduce the amount of air it takes in so less of the boost is wasted when you release the accelerator. You can even see this in BeamNG.... notice how boost falls rapidly when shifting gears in a petrol but much slower in a diesel. - Usually and especially at high load, petrol engines tend to be non direct injected. This means that the highly volatile fuel air mixture has to survive the entire intake (piston moving down) and compression (piston moving up) stroke. To much heat/compression will cause knock... you cant have that. Meanwhile a diesel just takes pure air in.... so nothing can burn no matter how hot and compressed the cylinder is at the end of the compression stroke. Only then, fuel is direct injected into the hot air and self ignites which is btw the reason why diesels run less refined than petrol engines. So in summary... a diesel has no limit in terms of boosting beyond the ability of the engine to withstand the stress and the capability of the fuel injection to deliver. You could in theory boost a modest 1.6 L turbo diesel all the way up to 2000 HP.... you just shouldnt assume for it to survive for more than a rew rotations. Of course you still can supercharge a diesel... but why would you? Turbocharging it has all the benefits and little drawbacks.
Well, the turbocharger uses energy from the exhaust that otherwise would've been wasted. I like that idea. The super charger needs extra energy. Some engines combine super charger and turbos. For fast boost and then efficient use
Turbocharger produce manifold pressure/back pressure which the engine then has to overcome as a pumping loss, aswell as the reduced ability to scavange with turbo as exhaust manifold is always higher pressure than intake. The efficiency between modern superchargers and turbos isnt as far apart as people make out. Best to have both
@@tobiaslmetters Sort of like the 2016 Zenvo ST1 which has a Supercharged and Turbocharged 7.0 Litre LS7 V8 that Produces 1,104 horsepower. In my opinion it's advantage is it has the instant pickup speed of a Supercharged car and has the horsepower of a Turbocharged car combined because the supercharger will help with Turbo lag.
Gale Banks at Banks Performance built a Duramax for the Heavy D from diesel bros for the Bro Dozer monster truck. It's on par with the blown big block methanol engines in the other monster trucks.
A Supercharger may sound great but a Turbocharger makes a Diesel engine more efficient and thus a better pair for it. Plus this particular Turbocharger isn't the quietest one, it sounds decent. I think you can make this test even harder: behind the Half Pipes, there's a massive ramp climbing them all the way up to the top. It has about the same incline as the ramp shown here but it's much longer (naturally). The greater length of it will make this test more challenging for the durability of the engines, I believe. There's also the classic 1-in-3 hill lying nearby, but that has its asphalt covered in a thin film of water, so it's kinda slippery.
Not gonna lie, I didn’t expect either of them to make it up there with the trailer. I prefer all motor (NA) for instant throttle response, so for my driving preference I like a blower. *(not an N/A diesel) But you make quite a few sacrifices for a positive displacement device, compared to a turbo being very efficient since it’s using exhaust energy rather than adding parasitic drag. The turbo is a far more practical choice for every day. But dang if I don’t love the sound and response of a blower. *also to my understanding, unless you have a clutch/ bypass you’re always going to be making boost with the blower so you have to use more fuel to avoid lean combustion in a gas car.
N/A diesels are generally pretty awful though. Works fine for gasoline engines, but (4 stroke) diesels pretty much need a turbo in order to make appreciable power.
@@AliceC993 yeah, I prefer NA in the more general sense. Not in a diesel but just as a driver/ sim racer. Exactly, NA diesels may be zombies, but that’s only because they’re all iron and have no power 😂. My daily is a 2001 tdi 5 speed. I love turbos and all, but having to be mindful of building and holding boost isn’t as fun as just having all your “ass” the instant you touch the gas. It’s easier to feather an NA in a slide/drift imo. Not hard to do in a turbo either, but you have to account for the split second it takes for boost to build and be mindful that you don’t get the compressor below it’s ideal rpm’s and bog down or lose all your boost.
Turbos are not free energy or ever almost free, that is impossible. They use centrifugal force of the fly wheel pushing the engines exhaust gases out. the best version of having both is how the F1 use it. Turbos as generators, to battery to store energy, then to electric superchargers. Equals zero lag and able to use higher boost when needed, because you're not limited to the engine's rpm/exhaust speed.
they’re basically free in comparison to a supercharger. My wording was intended to contrast re-capturing energy from the exhaust vs putting a literal air compressor on the belt system. A turbo will sap the engine of very very little power compared to the parasitic drag from running the supercharger.
I think further testing like this should include use of low gear, and locked diffs, as these may also affect the trucks' pulling and climbing. At the very least, locking the diff might, as if these are simply RWD trucks, without the diff locked, they only have one wheel pushing them up the hill. I think with the diff locked, and both rear wheels going, as well as using low gear, they could pull more weight and better use the torque.
Wow that was a long sentence. What do you mean "at the very least, locking the diff might, as if these are simply RWD trucks, without the diff locked, they only have one wheel pushing them up the hill" that makes no sense? Did you mean "locking the diff might help because an open differential only has one wheel putting power to the ground as these are RWD trucks?"
Not the case. Open differentials do look for the path of least resistance meaning that once a wheel loses traction all the power goes to that wheel. Until then the differential equally distributed power to both wheels as neither is the path to less resistance. If only one wheel was powered it would severely pull in one direction, especially large semi trucks with thousands of foot pounds of tourque and incredibly advantageous gearing.
An open diff sends 50% of the torque to each wheel in a perfect world. An open diff takes the path of least resistance, so in practice whichever wheel has more traction receives more torque. Very very old cars DID actually have what was called a "peg leg" layout, where only a single wheel was driven. This was done before the advent of the open diff to prevent the wheels from scrubbing during turns as would happen if both were driven.
The issue I have with doing this is the converter, you can run a much tighter converter with a supercharger than you can with a turbo car. It's evident here when you use the same converter and the supercharger slips it more, could this affect the test? Absolutely.
Is there a way to modify the stall of the transmission torque converter ? Because neither engines were brought down to their peak torque RPM range. Basically the torque converter was stalling too high up.
Looking at the torque curves on these I think the supercharger would be better for taking off and accelerating, but overall for cruising and fuel economy the turbo would be best. I think the reason the supercharged motor also does better on the seal climb is because it has that better mid-range to assist with acceleration. So instead of it really having more power to pull itself over it's the fact that it's able to have more speed at each point. Because if you notice once they're going up the hill even though the supercharger has 80 or 100 more lbft by the time you're sitting at 3,000 RPM it really only has about 20 more foot pounds of torque. It also makes me kind of feel like the comparison isn't exactly great. There is tuning that you can do to both of these two more so even them up. The supercharger seems more set up for mid-range and the turbo seems more set up for high-end, but it seems off. I also kind of wonder if either of these systems account for a intercooler. It's rare for supercharger to have intercoolers, but on something like this application a air to water intercooler wouldn't be a bad idea between the supercharger and the engine to cool down the intake charge because it's going to be freaking hot. The same question could be asked about the turbo setup and if it has an air to air intercooler. I feel like under a real stress test the air to air intercooler would probably work better if it was pressed for a longer period of time.
Very interesting. In real life the turbo truck would make more power at the same boost level tho due to the parasitic losses of spinning a supercharger
One of the best experiments I've seen. I like both turbos and blowers, but blowers take less space in the engine, so I think they're really really convenient.
@@jackmagnium6115 There's a multitude of reasons people don't drop turbos in favor of a supercharger is parasitic losses. Steve Morris engines fiddled with the concept awhile back and made a handy little data sheet on the amount of power it takes to drive a blower(114MM F2 Procharger IIRC) and the figures were insane. The RPM limitations for diesels also limits most superchargers off the shelf as they're geared more towards high RPM power. Sure, you could throw some insane pulleys on them to get proper blower rotation at 3-4k rpm but..people are too lazy. Scavenging the fluids from the exhaust is just better overall, efficiency wise, as well since it's free power. Turbos also help reduce EGT temps, cruising behavior, cleaner packaging, and a host of other features.
@@MrPanaramuh then again your forgetting something. highly modified diesel engines especially those used in drag racing and pulling. spin up to 7000 RPM's thats more than enough to drive a procharger. as for the PDS or positive displacement supercharger. Gale banks has proven time and again those are very effective. heck even wagler performance which has two screw blown duramax engines. and they are not to be messed around with. this is one of the trucks with a screw blown duramax ua-cam.com/video/0DRfjH-dVQI/v-deo.html
@@jackmagnium6115 well, sure. Those are performance based motors. We're talking run of the mill factory here. Turbos are just more efficient in this manner for the cost, package availability, and other bonuses over a supercharger. Not saying blowers DONT make power its just better for manufacturers to use turbos over superchargers.
@@MrPanaramuh not sure how an exhaust restriction helps with EGT temps but go on... And exhaust pressure is not free... now the piston has to do work to shove the gases out and drive said turbo instead of driving the load. Long story short, there's no such thing as a free lunch.
On big 2stroke diesels they did have a supercharger but it didn’t work the same as you would think. The 6v71 Detroit used a supercharger and a turbo on the engine the supercharger was used to get rid of the exhaust gas out of the cylinder And was known as a scavenge blower
but thats with a PDS or positive displacement supercharger. idk how something like a procharger(there is a procharged 6.0 Powerstroke that bruce wilson showed on his channel). if i had to guess. the procharger is gonna be in between a turbo and a PDS.
Supercharger vs Turbocharger One of the most commonly used ways to give a vehicle more horsepower and torque is by forced induction. There are two different ways to force induct a vehicle. One is a Supercharger, and the other is a Turbocharger. The conflict with this between people is deciding which one is better. Both superchargers and turbochargers have their advantages and disadvantages, some of which are similar. Choosing the right kind of forced induction will depend on your vehicle’s motor, and your power expectations. The first type of forced induction system is a supercharger. There are different types of superchargers. The first type is a root supercharger which is the oldest by far. Root type superchargers push extra oxygen into an engine by using meshed-lobe rotors. The rotors rotate in opposite direction trapping the air into pockets and forcing it from the inlet to the compressor chamber where it is compressed and moved into the engine. Root type chargers are simple and have few parts which results in reliability and require very few repairs. They are also good for adding power to an engine at low rpm’s. The second type of supercharger is the Screw. The screw type supercharger works very similarly to root type chargers. Screw superchargers are very good at moving air and lose very little of it. They can compress air as they move using their screws. The last type of supercharger is a Centrifugal supercharger. They are very similar to many pumps or fans. They pull air through an intake or compressor housing using an impeller which collects the air and forces it out into a progressively smaller Hodges 2 area, compressing it and leading it to the engine. Centrifugal chargers are excellent at moving large volumes of air. They are amongst the most efficient and effective superchargers. They also have few moving parts which makes them quiet, reliable, and require little maintenance. They also generate less heat then their more complicated equivalents. Of all types of superchargers, they all are effective at delivering boost almost instantaneously due to them being driven by a belt connected to the crank. This instant boost means more power instantly to the engine. Superchargers also have disadvantages. The biggest and main problem with superchargers is that since they are driven by a belt connected to the crank to deliver instant power, they are not as effective as obtaining as much power as a turbocharger, because a supercharger takes power to make power. The belt that drives the supercharger to make power, takes engine power to rotate. A supercharger engine loses approximately 20% of its potential power because it is belt driven. Another problem is that if your supercharger is setup to produce 10psi of boost, it will not make its full 10psi until the motor is revving almost as high as it will rev. Root superchargers are not good at producing high horsepower in high rpm’s which is generally why you find them on engines that operate at lower rpm’s. Screw superchargers are significantly less powerful before reaching high rpm’s. If used on engines that never reach high rpm’s, they never reach their potential. Centrifugal chargers put a limited amount of pressure on air. They also perform less effectively at low rpm’s. The other type of forced induction system is a turbocharger. A turbo operates almost the same way a centrifugal supercharger would, except it is not driven by pulleys and belts connected to the engines crankshaft. Turbochargers are driven by the engines exhaust gasses that have been removed from the engine and driven through a turbo manifold. The turbo manifold is connected to the turbo’s exhaust housing that takes the engine exhaust gasses and spins a turbine that drives the impeller Hodges 3 in the compressor housing which compresses the air the same way a centrifugal supercharger does, and sends the compressed air through a intercooler , if equipped, to cool down the compressed air and leads it to the engine’s intake. The higher the engine revs, the more exhaust gas is created to drive the turbine. Once the turbo is driving compressed air to the engines intake, that compressed air is now creating more volume of exhaust gasses which in turn means spinning the turbine in the turbo faster and faster. A turbo will create as much boost depending on the size of the turbo, and how much exhaust gas the engine sends through the exhaust housing to spin the turbine or the engine size. A turbo can add mass amounts of power to an engine and require no extra power to make power because it is driven off the exhaust gasses. There are hundreds of different types of turbochargers. The different types are all based on their size of the exhaust and compressor housings, the type of flange they have, and the type of bearings they have. Each and every different turbo is rated on how much air it can deliver to the engine. The bigger the turbine, typically the more air it can deliver at full boost. But the bigger the turbine, the more exhaust can pass through, reducing back pressure. The problems with turbochargers, is that they are very complex. A lot more parts are involved. Turbos create a lot of heat because of the exhaust gasses which means it makes them vulnerable to damage the turbo bearings which will shorten the life of it. The only way to limit the amount of maximum power a turbo will create to provide to the engine, is with a wastegate. There are turbochargers with internal wastegates that are built in the turbo’s exhaust housing, and some with external wastegates that are mounted to the turbo manifold. They both do the same thing which is to release some of the exhaust gasses from an engine into the atmosphere before it reaches the turbine which puts a limit on the amount of exhaust spooling the turbine. The wastegate valve opens and closes with the pressure in the intake. Vacuum pulls it shut and positive pressure or boost opens it to release Hodges 4 the exhaust gasses. Sometimes, the wastegate valve will stick and not open to release exhaust which sends all the exhaust to the turbine and can dangerously over boost an engine’s ability to withstand it and destroy and engine internally. A blow off valve or BOV is connected to the charge pipe that contains the compressed air going to the engine. A BOV is not just made to make a cool “pshhhh” sound, it si made to protect the turbo from damage. When a turbo is sending the compressed air to the engine, and the throttle body on the intake shuts from letting off the gas pedal when driving, all the compressed air is trapped in the charge pipe and the easiest way out if back through the turbo’s intake system. If this happens and the turbo is under full or high boost, it can damage the turbine, turbo seals, bearings, and the compressor impeller, altogether, destroying a turbocharger. The BOV is placed on the charge pipe near the throttle body and will remain shut until the throttle body closes. Once it closes, the excess pressure in the charge pipe is released through the BOV, making the cool “pshhhh” sound and protects the turbo. The other biggest main problem with a turbocharger is a good/bad thing. Although turbos can create huge amounts of extra power for an engine, they have what is called “spool time” or “lag”. The bigger the turbo, the more power it is capable of making, but in return, the bigger is it, the longer it takes to spin up to create boost. This is called lag. The turbo must actually spool up before it will compress any air because it is driven by exhaust gasses. Lag is the time it takes for the turbine to reach its full throttle from an average rotational speed state. During this time, little or no boost is created which means no power gains for a faster acceleration. The smaller the turbo, the less lag is created for a faster acceleration, but the less maximum power is generated. Depending on your engine size will depend on the proper size turbo application for an engine. The differences between superchargers and turbochargers are endless and each person will have his or her opinion on which is better based on their engine. It is defiantly certain that the Hodges 5 turbocharger will produce more power and is more efficient which is the purpose of forced induction, but on the other hand, a supercharger produces no lag and a lot less complex. Everyone has their own preferences so there is no winner in which is better. Choosing which one to run depends completely on the type of setup you want and how you want to run it, your power goals, and they type of engine you have.
Banks also used a supercharger on a hillclimb semi at Pike's peak about 10 15 years ago. Not stock but the supercharged diesel was much better than the old twin turbo set up that was used the year before. But agreed that it's not ideal for efficiency compared to a turbo.
Is there a mod that adds all these customization options? I have some customizability but nothing close to this. Another question... Is there a way naturally in-game to change engine displacement, boost levels, etc?
You can use different engines for the cars and them have different displacement, 4.5l, 6.0l, 6.9l and more. If you want to customize the boost, use a variable boost turbocharger.
for me i would go with more torque. since i do drag race in alot of games and my vehicles are AWD bricks. i need as much torque as i can get so i can get off the line fast
in real life the super charger is used on 2 stroke diesels like screaming Jimmy's 461-861 . first number is how many cylinders and the 61 is the cubic inches of the cylinder. they came in 3 to 16 cylinders , in inline and v configurations. from generators to tactors/forklift too semi trucks to ships and trains. all ran screaming Jimmy's super charged or they couldn't run!
Imo, the optimum setup without craziness is bi-turbo hybrids with quite large intercooler and maybe small supercharger, plus electric exhaust turbine for eliminating back pressure and fine tuned intake resonator. With this amount of air, engine must be quite sturdy. ( also nice looking 'sona )
In the real world, Detroit used superchargers on diesels from the 60s to 80s. The engines actually couldn't run without them. These diesels were also 2 stroke and powered everything from light trucks to huge ships, alot of busses from the 70s and 80s used supercharged Detroit 2 strokes (detroit 6v71 was common)
as someone said those where to provide scavenging and push the exhaust out as because 2 strokes dont have a vacuum to get air in and since those superchargers dont compress the air inside of the supercharger body they provide atmospheric air instead and pushes them to the cylinder
The torque converters could have been way tighter. A diesel without moving should only rev to 1400 revs. Sooooo that would be a much better test as your getting real world examples
well but technically you are not supposed to be running redline or close to it on a diesel since the most torque is made around 2000rpm at 3000rpm you are loosing torque even tho you making max hp, also no one, and i repeat, absolutely no one does a climb that steep on a high gear ratio, its always on a low gear ratio, you want torque nor power for a climb like that, so for a realistic test this is far from it if we start considering all of the aspects
@@ForgottenMustard ok well I meant like centrifugal or roots rype, etc. I was trying to figure out why it would whistle. Maybe just an oversight by whoever did the audio and design
Personally I would prefer a supercharger for avoiding that irritating turbo lag, but the turbo would probably be cheaper to service and are known to be reliable on a diesel, so based on that the turbo is probably the better option, but if money weren’t a concern I’d go with the SC
Cool simulation but truth told the automatic transmissions will puke on that angle. The pump can cavitation with all fluid at rear of case. I use 4speed granny and never fail. Centerforce Clutch type II
Both perform very well especially under load but let’s compare this to reality and think about the cost of going from turbo to a blower setup. Is it really worth it knowing they will compare almost identically?
But with that supercharger you going to have better throttle response. And no lag far as boost having to wait for the engine to get in the right RPM range for the booster kick in. Supercharger you don't have to do that just hit the gas and go don't have to wait
The difference here is the extra 1.6psi boost from supercharger, just increase the turbo psi to 22.1psi instead 20.5psi and see the numbers. Turbocharger is more efficient and drains almost no residual power from the engine, so at the same boost turbo makes more power (due to a lack of dragging a belt and moving a compressor)
surely this game hasn't calculated the parasitc draw for the supercharger, theres no way it would make comparable power or torque at 22psi of boost in comparison to a turbo, the sc would be drawing at least 50hp and 100ish lb-ft probably pushing closer to 100hp and like 200ish lb-ft to make that boost. not to mention the sc would have to be massive or overdriven like crazy to be able to move that much air at the engine speeds them larger displacement diesels run at.
turbo ftw, root blowers are very very prone to heat soak, definitely something you DONT want on a towing rig. it would be interesting to compare a turbo to a centrifugal supercharger though, they dont have heat soak issues like root blowers.
If I had a 6 litre v8 Commodore and I had a choice to put either on, I know in my head the turbo is better all round but I still would put a supercharger on it.
Dude with these diesel engines you don't want them to rev so high with the blue truck it looks like about 1900 or 2000 rpm would be your sweet spot and with the red you wanna put it at 2000 or 2100 it looked like
You'd need one he'll of a supercharger to make 22 psi at 3600 rpms or whatever they're revving to. This is incredibly unrealistic like most of the other videos I've seen from this program
been scrolling for ages hoping to find someone that has some form idea... yours is the only comment that hints at understanding why this is the biggest load of shit ive seen.
IRL blowers makes less max torque. even more so in a diesel - they have more and hotter exhaust gasses - they push a lot of gasses out at a very low RPM. a supercharger will be better at 1 rpm to idle rpm - in short i would really only help it crank up better than a turbo.
That’s why Detroit’s had blowers they were 2 stroke diesal and they mad alright power but would pull I also seen a guy put a blower on a 7.3 idi Ford and it pulled and ripped the tires off
For everyone else: Detroit Diesels need blowers because they are two stroke engines - the intake ports are at the bottom of the cylinder, the exhaust at the top. The cylinder can't draw air into into it like a four stroke with intake ports at the top of the cylinder, air has to be blown in. To make any real power on a two stroke diesel, it will be turbocharged.
@@Jabberwocky918 true I’m just saying tho atleast they came with blowers and it was diffrent gotta remember tho Detroit’s were made back in the day to nothing modern
Seems like to me supercharger would be better far as performance go torque is instant you can tell in the video. Far as the turbo there's a lag . Now I alot of people going to talk about efficiency and feel economy is a lot better set up turbos are. I don't know I'm a big supercharged head if they would have put superchargers on semi trucks they will be a lot more quicker I tell you that much
"in real life superchargers were never used in 4 stroke diesel pickup trucks" You clearly haven't been in a mud runner mechanics garage I have seen some things to make you question why we did it in the 1st place
If anyone is curious supercharged Diesel's did exist from the factory but they're stupid rare.

Mazda 626/Capella Comprex
2 stroke diesels need superchargers just to operate.
@@mmllmmll22 oh yeah for sure I kind of mentioned that in my little tidbit but that's why I didn't go into Detroit's. It operates in functions significantly different than a four-stroke motor
I’ve been kinda curious about getting the 2.0 Subaru diesel (turbo) and adding a mild supercharger to it.
The Turbo is a lot quieter doing what it does. I also would like to see a more real world pulling up a less steep slope but for a longer distance and seeing what heat, etc happens. On a hill like that, putting that much torque through probably would have broken something in the drivetrain or at least damaged it.
480LBFT Torque isn't going to damage anything regardless of slope.
A modern factory truck sized diesel transmission is good for more than 450 ft-lbs of torque.
^ this more real world tests. this test is pointless and would never happen.
You can make superchargers just as quiet as a turbo. Why superchargers aren't used on diesel pickups makes no sense to me

Well, the turbocharger uses energy from the exhaust that otherwise would've been wasted. I like that idea.
The super charger needs extra energy.
Some engines combine super charger and turbos. For fast boost and then efficient use
Or compound turbo systems. Best for efficiency with response much closer to na/sc.

Not gonna lie, I didn’t expect either of them to make it up there with the trailer.
I prefer all motor (NA) for instant throttle response, so for my driving preference I like a blower. *(not an N/A diesel)
But you make quite a few sacrifices for a positive displacement device, compared to a turbo being very efficient since it’s using exhaust energy rather than adding parasitic drag.
The turbo is a far more practical choice for every day. But dang if I don’t love the sound and response of a blower.
*also to my understanding, unless you have a clutch/ bypass you’re always going to be making boost with the blower so you have to use more fuel to avoid lean combustion in a gas car.
N/A diesels are generally pretty awful though. Works fine for gasoline engines, but (4 stroke) diesels pretty much need a turbo in order to make appreciable power.
@@AliceC993 yeah, I prefer NA in the more general sense. Not in a diesel but just as a driver/ sim racer.
Exactly, NA diesels may be zombies, but that’s only because they’re all iron and have no power 😂.
My daily is a 2001 tdi 5 speed. I love turbos and all, but having to be mindful of building and holding boost isn’t as fun as just having all your “ass” the instant you touch the gas.
It’s easier to feather an NA in a slide/drift imo. Not hard to do in a turbo either, but you have to account for the split second it takes for boost to build and be mindful that you don’t get the compressor below it’s ideal rpm’s and bog down or lose all your boost.
Turbos are not free energy or ever almost free, that is impossible. They use centrifugal force of the fly wheel pushing the engines exhaust gases out. the best version of having both is how the F1 use it. Turbos as generators, to battery to store energy, then to electric superchargers. Equals zero lag and able to use higher boost when needed, because you're not limited to the engine's rpm/exhaust speed.
they’re basically free in comparison to a supercharger.
My wording was intended to contrast re-capturing energy from the exhaust vs putting a literal air compressor on the belt system.
A turbo will sap the engine of very very little power compared to the parasitic drag from running the supercharger.
@@Forbiddina it still takes the same hp to make 1 PSI of air... it's a known quantity of work to compress air no matter how you do it.
I think further testing like this should include use of low gear, and locked diffs, as these may also affect the trucks' pulling and climbing. At the very least, locking the diff might, as if these are simply RWD trucks, without the diff locked, they only have one wheel pushing them up the hill. I think with the diff locked, and both rear wheels going, as well as using low gear, they could pull more weight and better use the torque.
Wow that was a long sentence. What do you mean "at the very least, locking the diff might, as if these are simply RWD trucks, without the diff locked, they only have one wheel pushing them up the hill" that makes no sense?
Did you mean "locking the diff might help because an open differential only has one wheel putting power to the ground as these are RWD trucks?"
@@Dave-dh7rt Fact - You was not hugged as a child.
Not the case. Open differentials do look for the path of least resistance meaning that once a wheel loses traction all the power goes to that wheel. Until then the differential equally distributed power to both wheels as neither is the path to less resistance. If only one wheel was powered it would severely pull in one direction, especially large semi trucks with thousands of foot pounds of tourque and incredibly advantageous gearing.
An open diff sends 50% of the torque to each wheel in a perfect world. An open diff takes the path of least resistance, so in practice whichever wheel has more traction receives more torque. Very very old cars DID actually have what was called a "peg leg" layout, where only a single wheel was driven. This was done before the advent of the open diff to prevent the wheels from scrubbing during turns as would happen if both were driven.

The issue I have with doing this is the converter, you can run a much tighter converter with a supercharger than you can with a turbo car. It's evident here when you use the same converter and the supercharger slips it more, could this affect the test? Absolutely.
Imo it still is too loose with the turbo
@@tyler6602 I agree
Is there a way to modify the stall of the transmission torque converter ? Because neither engines were brought down to their peak torque RPM range. Basically the torque converter was stalling too high up.
Looking at the torque curves on these I think the supercharger would be better for taking off and accelerating, but overall for cruising and fuel economy the turbo would be best.
I think the reason the supercharged motor also does better on the seal climb is because it has that better mid-range to assist with acceleration. So instead of it really having more power to pull itself over it's the fact that it's able to have more speed at each point. Because if you notice once they're going up the hill even though the supercharger has 80 or 100 more lbft by the time you're sitting at 3,000 RPM it really only has about 20 more foot pounds of torque. It also makes me kind of feel like the comparison isn't exactly great. There is tuning that you can do to both of these two more so even them up. The supercharger seems more set up for mid-range and the turbo seems more set up for high-end, but it seems off.
I also kind of wonder if either of these systems account for a intercooler. It's rare for supercharger to have intercoolers, but on something like this application a air to water intercooler wouldn't be a bad idea between the supercharger and the engine to cool down the intake charge because it's going to be freaking hot. The same question could be asked about the turbo setup and if it has an air to air intercooler. I feel like under a real stress test the air to air intercooler would probably work better if it was pressed for a longer period of time.
Very interesting. In real life the turbo truck would make more power at the same boost level tho due to the parasitic losses of spinning a supercharger
It really wouldn’t be that big of a deal considering the extra energy in diesel let alone the massive weight of the rotating assembly
@@Swatkiller7 still make quite a difference
One of the best experiments I've seen. I like both turbos and blowers, but blowers take less space in the engine, so I think they're really really convenient.
depends. im not 100% why people dont supercharge a factory 4 stroke diesel. a supercharger is great cause it provides alot of bottom end tourque
@@jackmagnium6115 There's a multitude of reasons people don't drop turbos in favor of a supercharger is parasitic losses. Steve Morris engines fiddled with the concept awhile back and made a handy little data sheet on the amount of power it takes to drive a blower(114MM F2 Procharger IIRC) and the figures were insane. The RPM limitations for diesels also limits most superchargers off the shelf as they're geared more towards high RPM power. Sure, you could throw some insane pulleys on them to get proper blower rotation at 3-4k rpm but..people are too lazy. Scavenging the fluids from the exhaust is just better overall, efficiency wise, as well since it's free power. Turbos also help reduce EGT temps, cruising behavior, cleaner packaging, and a host of other features.
@@MrPanaramuh then again your forgetting something. highly modified diesel engines especially those used in drag racing and pulling. spin up to 7000 RPM's thats more than enough to drive a procharger. as for the PDS or positive displacement supercharger. Gale banks has proven time and again those are very effective. heck even wagler performance which has two screw blown duramax engines. and they are not to be messed around with.
this is one of the trucks with a screw blown duramax
ua-cam.com/video/0DRfjH-dVQI/v-deo.html
@@jackmagnium6115 well, sure. Those are performance based motors. We're talking run of the mill factory here. Turbos are just more efficient in this manner for the cost, package availability, and other bonuses over a supercharger. Not saying blowers DONT make power its just better for manufacturers to use turbos over superchargers.
@@MrPanaramuh not sure how an exhaust restriction helps with EGT temps but go on... And exhaust pressure is not free... now the piston has to do work to shove the gases out and drive said turbo instead of driving the load.
Long story short, there's no such thing as a free lunch.
On big 2stroke diesels they did have a supercharger but it didn’t work the same as you would think. The 6v71 Detroit used a supercharger and a turbo on the engine the supercharger was used to get rid of the exhaust gas out of the cylinder And was known as a scavenge blower
but thats with a PDS or positive displacement supercharger. idk how something like a procharger(there is a procharged 6.0 Powerstroke that bruce wilson showed on his channel). if i had to guess. the procharger is gonna be in between a turbo and a PDS.
“Now ol Red he’s the damnedest dog…that I’ve ever seen..”
id like to see a 1/4 mile run with them both loaded at 10000 pounds
Supercharger vs Turbocharger One of the most commonly used ways to give a vehicle more horsepower and torque is by forced induction. There are two different ways to force induct a vehicle. One is a Supercharger, and the other is a Turbocharger. The conflict with this between people is deciding which one is better. Both superchargers and turbochargers have their advantages and disadvantages, some of which are similar. Choosing the right kind of forced induction will depend on your vehicle’s motor, and your power expectations. The first type of forced induction system is a supercharger. There are different types of superchargers. The first type is a root supercharger which is the oldest by far. Root type superchargers push extra oxygen into an engine by using meshed-lobe rotors. The rotors rotate in opposite direction trapping the air into pockets and forcing it from the inlet to the compressor chamber where it is compressed and moved into the engine. Root type chargers are simple and have few parts which results in reliability and require very few repairs. They are also good for adding power to an engine at low rpm’s. The second type of supercharger is the Screw. The screw type supercharger works very similarly to root type chargers. Screw superchargers are very good at moving air and lose very little of it. They can compress air as they move using their screws. The last type of supercharger is a Centrifugal supercharger. They are very similar to many pumps or fans. They pull air through an intake or compressor housing using an impeller which collects the air and forces it out into a progressively smaller
Hodges 2 area, compressing it and leading it to the engine. Centrifugal chargers are excellent at moving large volumes of air. They are amongst the most efficient and effective superchargers. They also have few moving parts which makes them quiet, reliable, and require little maintenance. They also generate less heat then their more complicated equivalents. Of all types of superchargers, they all are effective at delivering boost almost instantaneously due to them being driven by a belt connected to the crank. This instant boost means more power instantly to the engine. Superchargers also have disadvantages. The biggest and main problem with superchargers is that since they are driven by a belt connected to the crank to deliver instant power, they are not as effective as obtaining as much power as a turbocharger, because a supercharger takes power to make power. The belt that drives the supercharger to make power, takes engine power to rotate. A supercharger engine loses approximately 20% of its potential power because it is belt driven. Another problem is that if your supercharger is setup to produce 10psi of boost, it will not make its full 10psi until the motor is revving almost as high as it will rev. Root superchargers are not good at producing high horsepower in high rpm’s which is generally why you find them on engines that operate at lower rpm’s. Screw superchargers are significantly less powerful before reaching high rpm’s. If used on engines that never reach high rpm’s, they never reach their potential. Centrifugal chargers put a limited amount of pressure on air. They also perform less effectively at low rpm’s. The other type of forced induction system is a turbocharger. A turbo operates almost the same way a centrifugal supercharger would, except it is not driven by pulleys and belts connected to the engines crankshaft. Turbochargers are driven by the engines exhaust gasses that have been removed from the engine and driven through a turbo manifold. The turbo manifold is connected to the turbo’s exhaust housing that takes the engine exhaust gasses and spins a turbine that drives the impeller
Hodges 3 in the compressor housing which compresses the air the same way a centrifugal supercharger does, and sends the compressed air through a intercooler , if equipped, to cool down the compressed air and leads it to the engine’s intake. The higher the engine revs, the more exhaust gas is created to drive the turbine. Once the turbo is driving compressed air to the engines intake, that compressed air is now creating more volume of exhaust gasses which in turn means spinning the turbine in the turbo faster and faster. A turbo will create as much boost depending on the size of the turbo, and how much exhaust gas the engine sends through the exhaust housing to spin the turbine or the engine size. A turbo can add mass amounts of power to an engine and require no extra power to make power because it is driven off the exhaust gasses. There are hundreds of different types of turbochargers. The different types are all based on their size of the exhaust and compressor housings, the type of flange they have, and the type of bearings they have. Each and every different turbo is rated on how much air it can deliver to the engine. The bigger the turbine, typically the more air it can deliver at full boost. But the bigger the turbine, the more exhaust can pass through, reducing back pressure. The problems with turbochargers, is that they are very complex. A lot more parts are involved. Turbos create a lot of heat because of the exhaust gasses which means it makes them vulnerable to damage the turbo bearings which will shorten the life of it. The only way to limit the amount of maximum power a turbo will create to provide to the engine, is with a wastegate. There are turbochargers with internal wastegates that are built in the turbo’s exhaust housing, and some with external wastegates that are mounted to the turbo manifold. They both do the same thing which is to release some of the exhaust gasses from an engine into the atmosphere before it reaches the turbine which puts a limit on the amount of exhaust spooling the turbine. The wastegate valve opens and closes with the pressure in the intake. Vacuum pulls it shut and positive pressure or boost opens it to release
Hodges 4 the exhaust gasses. Sometimes, the wastegate valve will stick and not open to release exhaust which sends all the exhaust to the turbine and can dangerously over boost an engine’s ability to withstand it and destroy and engine internally. A blow off valve or BOV is connected to the charge pipe that contains the compressed air going to the engine. A BOV is not just made to make a cool “pshhhh” sound, it si made to protect the turbo from damage. When a turbo is sending the compressed air to the engine, and the throttle body on the intake shuts from letting off the gas pedal when driving, all the compressed air is trapped in the charge pipe and the easiest way out if back through the turbo’s intake system. If this happens and the turbo is under full or high boost, it can damage the turbine, turbo seals, bearings, and the compressor impeller, altogether, destroying a turbocharger. The BOV is placed on the charge pipe near the throttle body and will remain shut until the throttle body closes. Once it closes, the excess pressure in the charge pipe is released through the BOV, making the cool “pshhhh” sound and protects the turbo. The other biggest main problem with a turbocharger is a good/bad thing. Although turbos can create huge amounts of extra power for an engine, they have what is called “spool time” or “lag”. The bigger the turbo, the more power it is capable of making, but in return, the bigger is it, the longer it takes to spin up to create boost. This is called lag. The turbo must actually spool up before it will compress any air because it is driven by exhaust gasses. Lag is the time it takes for the turbine to reach its full throttle from an average rotational speed state. During this time, little or no boost is created which means no power gains for a faster acceleration. The smaller the turbo, the less lag is created for a faster acceleration, but the less maximum power is generated. Depending on your engine size will depend on the proper size turbo application for an engine. The differences between superchargers and turbochargers are endless and each person will have his or her opinion on which is better based on their engine. It is defiantly certain that the
Hodges 5 turbocharger will produce more power and is more efficient which is the purpose of forced induction, but on the other hand, a supercharger produces no lag and a lot less complex. Everyone has their own preferences so there is no winner in which is better. Choosing which one to run depends completely on the type of setup you want and how you want to run it, your power goals, and they type of engine you have.
Banks also used a supercharger on a hillclimb semi at Pike's peak about 10 15 years ago. Not stock but the supercharged diesel was much better than the old twin turbo set up that was used the year before. But agreed that it's not ideal for efficiency compared to a turbo.
Is there a mod that adds all these customization options? I have some customizability but nothing close to this. Another question... Is there a way naturally in-game to change engine displacement, boost levels, etc?
You can use different engines for the cars and them have different displacement, 4.5l, 6.0l, 6.9l and more.
If you want to customize the boost, use a variable boost turbocharger.
for me i would go with more torque. since i do drag race in alot of games and my vehicles are AWD bricks. i need as much torque as i can get so i can get off the line fast
What kinda mods do you have for BeamNG?
I wish diesel trucks had superchargers in real life.
in real life the super charger is used on 2 stroke diesels like screaming Jimmy's 461-861 . first number is how many cylinders and the 61 is the cubic inches of the cylinder. they came in 3 to 16 cylinders , in inline and v configurations. from generators to tactors/forklift too semi trucks to ships and trains. all ran screaming Jimmy's super charged or they couldn't run!
Torque...
As one wise man said "Horses sell car, torque drives it" 😅
Both if your Gale Banks. 🤷🏻♂️
Underrated comment
A quad twin-charger setup is where it’s at, IMHO. (Quad turbo + quad blower)
So, an octo-charger
Imo, the optimum setup without craziness is bi-turbo hybrids with quite large intercooler and maybe small supercharger, plus electric exhaust turbine for eliminating back pressure and fine tuned intake resonator. With this amount of air, engine must be quite sturdy.
( also nice looking 'sona )
Why aren't they breaking traction? The HD truck tires in this game all have terrible grip.
probably a mod that gives tires insane traction so that isn't a variable to work around.
Can we get an equal liter but different cylinder count comparison? something realistic?
Interesting fact - Mazda was probably the only car manufacturer using a Comprex compressor with a diesel engine. Look it up, pretty interesting stuff.
Both. Both would be good. Twincharging for the win XD
both is how F1 does it.
I had missed these videos
In the real world, Detroit used superchargers on diesels from the 60s to 80s. The engines actually couldn't run without them. These diesels were also 2 stroke and powered everything from light trucks to huge ships, alot of busses from the 70s and 80s used supercharged Detroit 2 strokes (detroit 6v71 was common)
as someone said those where to provide scavenging and push the exhaust out as because 2 strokes dont have a vacuum to get air in and since those superchargers dont compress the air inside of the supercharger body they provide atmospheric air instead and pushes them to the cylinder
The torque converters could have been way tighter. A diesel without moving should only rev to 1400 revs. Sooooo that would be a much better test as your getting real world examples
Turbo is better for efficiency but the supercharger makes more torque either way turbo is better in my heart
well but technically you are not supposed to be running redline or close to it on a diesel since the most torque is made around 2000rpm at 3000rpm you are loosing torque even tho you making max hp, also no one, and i repeat, absolutely no one does a climb that steep on a high gear ratio, its always on a low gear ratio, you want torque nor power for a climb like that, so for a realistic test this is far from it if we start considering all of the aspects
Best automotive game out there.
when it comes to unique vehicles here in Australia supercharged diesel engines are common cause they sound great
Excellent video. I can't help but notice the "whistling" sound is louder under load in the SC truck than on the Truck. What kind of SC is it anyway?
It's the stage 2 blower from the gas V8's.
@@ForgottenMustard ok well I meant like centrifugal or roots rype, etc. I was trying to figure out why it would whistle. Maybe just an oversight by whoever did the audio and design
Personally I would prefer a supercharger for avoiding that irritating turbo lag, but the turbo would probably be cheaper to service and are known to be reliable on a diesel, so based on that the turbo is probably the better option, but if money weren’t a concern I’d go with the SC
How did those Tires not slip? How do you give them this much grip?
Why didn't you use low range mode for the gearbox?
I have respect for both but i love the sound of the blower no doubt
Blower!
That trash automatic gearbox (slushbox) makes things complicated
Lock the torque converter. Then you'll get some real results
mabey in-game but IRL there a reason it's called a "torque" converter.
Blower, it is awesome
I’m high so I clicked on this video and it’s actually interesting lol
Now, twincharge it - both a turbo and a super
Cool simulation but truth told the automatic transmissions will puke on that angle. The pump can cavitation with all fluid at rear of case. I use 4speed granny and never fail. Centerforce Clutch type II
Actually banks makes a supercharger for Diesel engines. It’s fucking awesome.
Both perform very well especially under load but let’s compare this to reality and think about the cost of going from turbo to a blower setup. Is it really worth it knowing they will compare almost identically?
But with that supercharger you going to have better throttle response. And no lag far as boost having to wait for the engine to get in the right RPM range for the booster kick in. Supercharger you don't have to do that just hit the gas and go don't have to wait
The difference here is the extra 1.6psi boost from supercharger, just increase the turbo psi to 22.1psi instead 20.5psi and see the numbers. Turbocharger is more efficient and drains almost no residual power from the engine, so at the same boost turbo makes more power (due to a lack of dragging a belt and moving a compressor)
I did that towards the end of the video.
@@ForgottenMustard Oops my bad the video cut due to a internet issue and didn't saw the end, that was exactly I want to see
surely this game hasn't calculated the parasitc draw for the supercharger, theres no way it would make comparable power or torque at 22psi of boost in comparison to a turbo, the sc would be drawing at least 50hp and 100ish lb-ft probably pushing closer to 100hp and like 200ish lb-ft to make that boost. not to mention the sc would have to be massive or overdriven like crazy to be able to move that much air at the engine speeds them larger displacement diesels run at.
How you made supercharger save pressure? I added supercharger to my automation vehicle but it loses pressure after i release the gas pedal!
clutch has left the chat
turbo ftw, root blowers are very very prone to heat soak, definitely something you DONT want on a towing rig.
it would be interesting to compare a turbo to a centrifugal supercharger though, they dont have heat soak issues like root blowers.
One video 4x4 trail
And real Damage to shocks or other parts on motor or Drive train
😍
Only very few vehicles have supercharged diesel's and lots of them are 50's semi trucks but some tanks also have supercharged diesels
Should add a cvt to the blower, it would change the top speed too!
If I had a 6 litre v8 Commodore and I had a choice to put either on, I know in my head the turbo is better all round but I still would put a supercharger on it.
The french made a supercharged diesel suv
Guarantee the turbo is way more fuel efficient and cooler egts. Awesome idea though, don’t know why this never happened…
How do you mod engines n stuff? I can't.
Objective towing power or speed?
Fit for purpose.
Superchargers we’re used in Detroit diesels
I have had both turbo and supercharged vehicles. Since I'm a torque junkie I prefer the supercharger.
Super charger and turbo together on one truck.
Turbochargers improves diesels low down torque better than superchargers. And superchargers will heat soak in heavy duty applications.
1:14 i can smell clutch from here
this is why detroit diesels are supercharged and many tractor trailers
wrong
Turbo sounds way better tho imo lol
High torque
More hp
Vs
Average torque
More responsive.
i would like a supercharger, as it doesnt take time to spool up, plus its something i would use for drifting instead of antilag
Dude with these diesel engines you don't want them to rev so high with the blue truck it looks like about 1900 or 2000 rpm would be your sweet spot and with the red you wanna put it at 2000 or 2100 it looked like
You'd need one he'll of a supercharger to make 22 psi at 3600 rpms or whatever they're revving to. This is incredibly unrealistic like most of the other videos I've seen from this program
been scrolling for ages hoping to find someone that has some form idea... yours is the only comment that hints at understanding why this is the biggest load of shit ive seen.
Supercharger gives torque and turbo charger gives hp. So for a all rounder diesel engine we need twin charging system
Good game 🎮 👏
The super charger was used in Detroit motors examples like 8v92
I thought Detroit used twin charging?
but in real life turbo is the one who makes more torque than supercharger at same hp
Tune a turbo or use dual turbos and you will get your low end torque and high end.
there was no time for the turbo to spool
What is the dyno app called?
U gotta put in low more torque more pulling power
I'm a supercharger guy to my core and torque is the main purpose of a diesel, so I see no reason not to go with the Blower.
IRL blowers makes less max torque. even more so in a diesel - they have more and hotter exhaust gasses - they push a lot of gasses out at a very low RPM. a supercharger will be better at 1 rpm to idle rpm - in short i would really only help it crank up better than a turbo.
Strange, i always heard that superchargers are always weaker than turbos, becouse theyre less efficient
Torque is king all engines have power & torque power is generally how fast an engine can operate and torque is how strong the engine is
In trucking I'd choose supercharger
Anything else I'd go with a turbo
That’s why Detroit’s had blowers they were 2 stroke diesal and they mad alright power but would pull I also seen a guy put a blower on a 7.3 idi Ford and it pulled and ripped the tires off
For everyone else: Detroit Diesels need blowers because they are two stroke engines - the intake ports are at the bottom of the cylinder, the exhaust at the top. The cylinder can't draw air into into it like a four stroke with intake ports at the top of the cylinder, air has to be blown in. To make any real power on a two stroke diesel, it will be turbocharged.
@@Jabberwocky918 true I’m just saying tho atleast they came with blowers and it was diffrent gotta remember tho Detroit’s were made back in the day to nothing modern
I mean why not both best of both worlds, blower for lowdown torque and turbo for highend power
More realistic pulls
Put bigger gearing in it, maybe like 3.73, 4.10, or 4.81
Seems like to me supercharger would be better far as performance go torque is instant you can tell in the video. Far as the turbo there's a lag . Now I alot of people going to talk about efficiency and feel economy is a lot better set up turbos are. I don't know I'm a big supercharged head if they would have put superchargers on semi trucks they will be a lot more quicker I tell you that much
stutututututut
yooooo
Supercharger. You want to pull weight not cruise in a Prius. Instant and more torque is always better.
haha just put both on one engine much torque at low RPM (super charger) and much power at high RPM(turbo)
Unlimited traction unlocked
"in real life superchargers were never used in 4 stroke diesel pickup trucks" You clearly haven't been in a mud runner mechanics garage I have seen some things to make you question why we did it in the 1st place
My only complaint is that you arnt giving them enough run up
What about both?
blower for the win
Very good video
For my back woods area supercharger would be better in our mountains.
