Thank you for this. I always knew the difference in how they work, but not their advantages and disadvantages. The turbo revolutionised the diesel engine both in terms of torque and reduced fuel consumption. Also they are more reliable on diesels as they run at much lower revs (due to the higher compression ratio) and hence are cooler.
diesel torq and hp is from 300- 400 hp at 26 pounds of boost 100 hp from turbo at 2150 rpm only making boost taking off and when it hits hill going down road at 60 guage reads 0 super charger was more efficent on big trucks but costed dealer 1000 to make turbo costed dealer 25.00 to make Dads in old truck club
Mayor difference that you didn't mention: torque with a supercharger is linear, it increases simultaneously with the rpm when you are accelerating. Turbochargers have a mostly flat toque band, usually starting from 1500-2500 rpm all the way to redline, or it's tapers of at the end because the turbo is too small for adequate boost at the end.

@@wendellgreenidge3362 yes they are.

I have a slk230 kompressor for 7 years. Never needed maintenance on compressor and it responds right way. My daughter had a cx7 with turbo and just headache.
There are some other things worth mentioning. The free spooling turbocharger allows for altitude compensation. A supercharger is slaved to the crankshaft so as elevation and temperature increases (esp a combination of both) then the power adding the supercharger gives is lost as in an NA engine (albeit from a higher power potential). A turbocharger has a key advantage here as it can maintain manifold pressure automatically. A turbocharger also costs power in the form of pumping losses esp when it is on high boost but blower pumping loss is always there esp when cruising - whereas the turbo during cruise has little or no pumping loss sice it's off boost. Back to superchargers, in aviation some general aviation had a pilot selectable 2sp gearbox to compensate for altitude gain. As you can imagine it is problematic and turbochargers are simpler and lighter. So as you mentioned a turbo has a clear benefit. It can maintain rated power most of the time and doesn't cost fuel during cruise - however I still want a blower lol.
I think supercharger and turbochargers are both good. I think it depends more on what the purpose you are using the vehicle for. In my case, I want more response in everyday driving. I'm less interested with peak HP. If it was all about power, I'd probably go with turbo.
Imop there’s nothing like a supercharger down low when u hit the gas and get an instant response. Plus it sounds so damn good. I miss my revo stage 2 tuned Audi s4
Higher end Twin Screw Superchargers negate the efficiency loss and in select applications outperform turbo applications. Superchargers are also much much cooler than Turbos, and because they have boost on full the bypass is essential.

In summary think of supercharger as a bar that raises with pulley selection, initial size of motor vs literage of engine is only real dilemma, unmodified engines pay heavy penalties with supercharger. Turbo is a exponential slide, add tons of boost pay for it only on the low rpms, above about 2,200 rpm for most engines is usually enough to rotate even 76mm wheels pretty well, 80mm up you need exhaust manifolds and an engine that has spunk on its own. Few notes, for supercharger nearly all stock superchargers are roots and TVS type, which are trash efficiency of about 40-70% versus TwinScrew and Centrifugal types which start over 80% and often exceed 90%. Centrifugal sc's are nearly completely louder than most would would like on street not often a pleasant noise, though some gearing and shrouds mitigate that not a great time, usually legal outcry if you have heavy police watch. Turbochargers operate somewhere between 76%(Ebay special) and 88%(IHI and most modern turbos) with some well selected ball bearing ceramics pushing 92+ on case by case at specific boost and operation routines. Issues with supercharging maintenance is far easier and install and removal usually basic. SC intercooler of fixed displacement (not centrifugal tube's with belts) are water to air, run risk of loss if damaged, limping is not usually risky. Superchargers run their own oil. Turbo and Centrifugal SC share risks and advantages with exception of heat. Lose the oil and/or water lines and it is a nearly certain fatality for the system. Tuning a fixed displacement supercharger like B8 is super steady consistent. Turbos can vary wildly based on temps and fuel output mapping errors or bad sensor readings. Research options both are fun for their own functions. Both operate almost same on street mileage if you pedal right below boost, but epic shifts in smiles are not exclusive to either.

In Australia we have the locally made Ford "Barra" inline six 4 liter with a factory turbo and no discernible lag with the factory turbo. The long stroke 4 liter 4-valve engine makes excellent torque from low revs which helps. There are some heavily modified Barra engines making over 2,000HP at the wheels. We also have the Holden, GM in Australia, Commodore which was exported to the USA as the Chevy SS running the LS3 V8 and a number of supercharger kits are available with efficient twin screw superchargers from the Magnuson 2300 to the Whipple based 2900. Best of both worlds really. The only problem is that both were discontinued in 2017 but there are plenty available used.
I've always been a huge proponent of a supercharger, and the sound, especially in a S4 w/ dual pulley and cai, is amazing. In saying that, I own a turbo 5cyl Volvo and I'm absolutely enamoured with turbos now! Honestly could not give an answer to the question of super or turbo, they're both so goddamn wicked!
The way the turbo pulls from spool to top end with that whistle is great. Plus being able to have the ability to adjust boost with a switch is so good. The instant off the mark hit of the supercharger is great. The noise is sexy. Swapping pulleys and belts to hit a boost target only for it to hit it at a certain RPM, before and after being low, is a touch annoying. The fix is obviously undersizing the pulley and running a bypass valve as a boost controller.
I guess depends on where you’re mounting them etc, engine size but I personally always thought mounting a supercharger especially on v8s is much easier than having to turbo them. Much more work to turbo one as well to fabricate all the pipes etc
Don't forget the audi superchargers have bypass valves, which allow for much better efficiency at low rpms. Also I approve of the use of the terms twisty thing and spinny wheels
@@ushyamamoto7098 Supercharger is a less complicated install, however it depends on how you want the power delivery. Supercharger for instant down low torque, turbo for more higher rpm punch. Availability of a kit is another concern.
I'm a supercharger guy. I'm not looking for outright the most power I can get. I like stock feel with an abundant of power at each rpm. And since superchargers are always boosting the instant power is very welcome. Can you imagine though if roots type blowers were not driven by the engine and still give instant power.
Not true. Actually to get real power from a supercharger you have to which engine components. Turbo you don't. Turbos are budget friendly and don't put a pounding on your engine. A supercharger puts a pounding on your engine and if you don't upgrade your engine components you will break something for sure. This is why when a company adds a supercharger on a car it doubles in price and not the case with a turbo.
@@rayshaunedwards6572 Actually it is the oposite, turbo,which nowdays usualy provides above 1 bar of boost in most factory non peformance cars puts more strain on the engine compared to equivelent supercharger that usualy puts out 0.5 bars. Also supercharger is easier to install onto a NA car most of the time compared to a turbo where you have to modify your car's oil feed and coolant supply to the turbo, not mentioning custom made exhaust manifold,mounting bracket,fueling and remaping involved. We are talking about basic turbo design there, while basic supercharger(roots type I think) just needs a mounting slot and a pulley, while stock ECU can compensate the extra 0.3-0.5 bars of air on it's own(of course it also depends on the size).
@@rayshaunedwards6572 any type of power adder (turbo, supercharger, procharger, nitrous) puts a strain on the engine components due to the higher amount of air and fuel being sent into the engine. A lot more vehicles are being made from factory with turbos because it doesn't cost as much compared to a supercharged vehicle. As the video stated, the supercharger robs the engine from horsepower (100 to be specific) while the turbo doesn't rob more than 30, if that. A car company will make a turbo 4 cylinder vehicle with it only using maybe 5 psi of boost and get into the 300 hp range with similar torque while maintaining 30 mpg. Companies are competing not only to be the fastest, but. Also the most fuel efficient at the same time. That's maybe the biggest reason why turbos are much more common than a supercharger
Crawford did an FA20 build where they hit peak boost at 3500rpm, the engine also made up to 720whp i think it was, so idk who would need a ton of power before 3500. And yes it was a small turbo which spools quickly and they still made insane power!
I was trying to decide which one sounded better and had to call it a tie. The turbo’s “fssssssstustustu” is godly in its own way, but a supercharger just sounds so mean😩
It really is a matter of choice but engines with the same displacement and number of cylinders make more top end power when turbocharged as opposed to supercharged.
And I beleive as the efficacy aspect of turbos, they add power and reduce emissions. Superchargers not so much, hence why manufacturers are veering away from superchargers and adding turbos to everything
Let me sit in the middle cause i have a vw golf 5 gt turbo*charged (this car is mostly European as i know but i haven't seen anything in US drop it down if you have. 1.4 tsi twincharged engine 170bhp) it still amaze me how it works and sounds especially the supercharger it sounds amazing 🔈🔉🔊👌🏼
another difference is in NA and Supercharged engines the hottest the engine oil gets is around ~200°C while in a Turbo engine the engine oil can get to 400°C as it cools the exhaust gas driven turbo. So all things being equal surely the Supercharged engine oil would be cleaner and less stressed over the oil change interval period.
Coming from a 8 valve G60 to a 20 valve 225hp 1.8t with the same displacement size engine in the same car ,its wayyyy more fun with a turbo. been on both sides of the fence, turbo for me. was cheaper and more reliable too
Should have mentioned the effects on engine lifespan of a turbo vs a super. I avoid turbos because I don't want to replace a worn out engine every 100,000 miles, the back pressure kills. Just makes sense when you're trying to force more air in but creating back pressure from exhaust restrictions that it would create excessive wear on the engine.
I think the simplest way to translate what you said into layman speak, supercharger gives you more performance at low RPM and Turbocharger gives you more performance at mid-high rpm. Now this is obviously subject to another phenomena, exhaust volume. As your engine volume increases your exhaust volume/flow increases. So you may be able to get the turbo to spool up at lower RPM's in some instances encroaching on the supercharger... at the same time larger engines have more HP to spare to push a turbo so still it comes down to off the line power (like a drag or 0-60 times) vs power at speed (passing acceleration on the road). I think that Turbos serve the common motorist best and super chargers are more a drag strip option, but again as you change the engine size/composition, and usage you'll see how the two work with your power train change a bit.
Just to add that you only get that sound on high pressure turbos. Low pressure turbos don't make any discernible sound, such as those in diesel car engines. But high pressure turbos DO sound great, totally agree ! 🥰🥰
Coming from experience with Turbos fuel efficiency is great up to the 3rd year of ownership. Due to the plumbing connecting it to the exhaust down pipes. The carbon build up causes a number issues causing check engine code (forgot the code) of Turbo OverBoost. Due to up of the carbon the internal veins lock up boost and horsepower is lost. Also, most think the system is light weight still have more tubing/pipe plumbing and brackets to add weight. If I would have a choice Super Charger is more reliable.
Superchargers seem to be great at the lower rpms and quick accelerations, turbo has greater fuel efficiency and rule the higher rpm part of the power curve because they have LESS parasitic drag. Any time you put some resistance AFTER your exhaust manifold you are robbing SOME power from the engine. You are hoping that the power gained offsets the extra work you are imposing on the engine.
@@Ethan007Hacks the engine just feels so much like a bigger V8 with the supercharger on it. I had a mazdaspeed6 prior to this and the turbo boost was apparent. And if I was sitting in hot traffic, I'd give it gas and it felt dead. The exact opposite with the supercharger.
@Samad Allah incorrect statement superchargers does heatsoak check your intake temps when running hard. I have a icetank in my srt6 to keep my intake temp around 40 degrees
2:57 that does not sound right: turbo easier to retrofit onto an engine. The turbo has lots of ducting that needs to be fit into the engine bay, and requires more engineering / calibration of parts to make it work well. A SC on the other-hand is a compact unit that fits into the space that formerly held the intake manifold. The inter-cooler plumbing is a couple of smallish water lines which is more compact and easier to route. Seems to me, the two main differences to consider are: -turbo has slightly less parasitic load when compared to a modern twin-screw SC. -SC naturally has zero lag / better throttle response. Turbo-lag can be greatly reduced, but takes some thought and tinkering. The turbo seems to get the advantage when you are doing a big run of cars, while SC seems to have the advantage for individual upgrades.
Just depends on the build and what you want to do with it. My 2.4CRV has a head w/manifold built in so a turbo would bolt directly to the Head. A little bit of Plumbing/fab for the intercooler. Run a new 3in cat exhaust Y'd off for dual 2.5in stock CRV Mufflers. For a quiet sleeper.
Hi @GT Godbear, I have a few questions for you. What's the configuration of the turbo inlet and outlet? Is it T3, T4 or V-band and at which A/R? Did you upgrade your fuel injectors for the turbo? Have your k24 CR-V boosted with Garrett turbo or Precision turbo? Did you put in an oil catch can? How many whp does your CR-V makes after the turbo setup?
S5's are slow af....what are you talkin abt....put an 'R' in front of the 'S' and now you're talking about something worthy of mentioning, but S5? come on, wake up.
@@farmanshaikh6405 This is a bit of a childish reaction, but I guess this is the internet so manners don't count. I rather had an RS but to be honest I couldn't afford one. I do about 3.8 sec to 100km/ph with my S5 which is really fast for me 😊. If you're car is faster, good for you👍
I'm definitely a supercharger lover but that's more about the looks and instant torque. Not saying a turbocharger is torque less cause we all know there not but when buying a base kit the supercharger is gonna give you that instant torque where as the turbocharger is gonna give you that top end power
Actually you can and it's relatively safe. Especially on a diesel. A turbo provides the low end torque and if you gun it, the supercharger kicks in. I would like to see BMW implement both turbo and supercharger on their M Series. If anyone can, it would be BMW.
See that sounds backwards turbos are more complicated to put on caused because you have to change the intake system the exhaust system and much more. Compared to just putting a supercharger on and hooking it up to your Crank
How is retrofitting a roots style supercharger more complicated than a turbo? With a Turbo you have to drill oil ports, lay oil lines, install wastegates an blow off valves, etc. With a supercharger you just need to isntall a mount (maybe custom weld one, or let weld by somebody), attach a pulley and its done.
Which is better on the engine and which one last longer? I'm not the type of person that lies to myself like I need every bit of power😂 either upgrade is going to increase power but I love reliability at a affordable price.
I like both and would use either for a build. But I do like the supercharger sound more. It's got the better whistle sound imo. But they both have pros and cons. So it comes down to personal preference. So everyone is different and will like more than the other. Especially if ones cheaper and you can get a deal? Because cars with high HP are expensive asf. And building a muscle car still is expensive asf. But it's cheaper to build yourself. Plus you get way more choices

My attainable dream car is the supercharged Mercedes E55 AMG, I love the sound of the car
Having a supercharged car makes even the smallest journey super memorable even in stop start traffic
This was actually very informative. Thank you.
No problem
I guess depends on where you’re mounting them etc, engine size but I personally always thought mounting a supercharger especially on v8s is much easier than having to turbo them. Much more work to turbo one as well to fabricate all the pipes etc
other people : hmm lets see advantages and disadvantages
me : which one sounds better
Don't forget the audi superchargers have bypass valves, which allow for much better efficiency at low rpms.
Also I approve of the use of the terms twisty thing and spinny wheels
Supercharged any day. Turbos burn up!
Turbo I like it
@SG2 February Procharger's are rpm dependent they don't make much boost until 4000 rpm. Roots or Twin Screw will make full boost around 2500 rpm.
PRO 5.0 I’m new to this can u explain more I have a Infiniti q40 I am deciding between supercharging it or adding turbos. Thanks 🙏🏾
@@ushyamamoto7098 Supercharger is a less complicated install, however it depends on how you want the power delivery. Supercharger for instant down low torque, turbo for more higher rpm punch. Availability of a kit is another concern.
Big facts
Literally the best explanation thank you- although I knew all this already I do now know which I prefer
I'm a supercharger guy. I'm not looking for outright the most power I can get. I like stock feel with an abundant of power at each rpm. And since superchargers are always boosting the instant power is very welcome. Can you imagine though if roots type blowers were not driven by the engine and still give instant power.
i leave my friends GTR instantly, my Jag's supercharger puts down instant torque and he has turbo lag
Keep banging these videos out dude, awesome content and information as always. 👏🏾👏🏾👏🏾
I prefer superchargers over turbos : reason its quicker too install and has instant power. Turbo motors needs more maintance.
Me too
Not true. Actually to get real power from a supercharger you have to which engine components. Turbo you don't. Turbos are budget friendly and don't put a pounding on your engine. A supercharger puts a pounding on your engine and if you don't upgrade your engine components you will break something for sure. This is why when a company adds a supercharger on a car it doubles in price and not the case with a turbo.
@@rayshaunedwards6572 Actually it is the oposite, turbo,which nowdays usualy provides above 1 bar of boost in most factory non peformance cars puts more strain on the engine compared to equivelent supercharger that usualy puts out 0.5 bars. Also supercharger is easier to install onto a NA car most of the time compared to a turbo where you have to modify your car's oil feed and coolant supply to the turbo, not mentioning custom made exhaust manifold,mounting bracket,fueling and remaping involved. We are talking about basic turbo design there, while basic supercharger(roots type I think) just needs a mounting slot and a pulley, while stock ECU can compensate the extra 0.3-0.5 bars of air on it's own(of course it also depends on the size).
@@rayshaunedwards6572 any type of power adder (turbo, supercharger, procharger, nitrous) puts a strain on the engine components due to the higher amount of air and fuel being sent into the engine. A lot more vehicles are being made from factory with turbos because it doesn't cost as much compared to a supercharged vehicle. As the video stated, the supercharger robs the engine from horsepower (100 to be specific) while the turbo doesn't rob more than 30, if that. A car company will make a turbo 4 cylinder vehicle with it only using maybe 5 psi of boost and get into the 300 hp range with similar torque while maintaining 30 mpg. Companies are competing not only to be the fastest, but. Also the most fuel efficient at the same time. That's maybe the biggest reason why turbos are much more common than a supercharger
What about 'sstutututu' sound?
Couldn’t find a better video for the subject, plus the extra info on the comments. 🙏🏼
Crawford did an FA20 build where they hit peak boost at 3500rpm, the engine also made up to 720whp i think it was, so idk who would need a ton of power before 3500. And yes it was a small turbo which spools quickly and they still made insane power!
Good show (no waffling on like a lot of the vids)
straight to the facts no mucking around plus a bit of humour....thanks
Now you are a magic man, a comedian, and a parts man.
Thanks for educating us here about this subject man..! Is never too late for us to learn something new..😉
My 2013 A6 3.0t at 75-80 Mph at cruise gets 31mpg but for instant passing just a simple press and I fly by everyone. Very solid and fun car
I'd buy the supercharged cause of the sound. The sound is GODLIKE
I was trying to decide which one sounded better and had to call it a tie. The turbo’s “fssssssstustustu” is godly in its own way, but a supercharger just sounds so mean😩
Volvos be like: aight we’ll give u both
It really is a matter of choice but engines with the same displacement and number of cylinders make more top end power when turbocharged as opposed to supercharged.
And I beleive as the efficacy aspect of turbos, they add power and reduce emissions. Superchargers not so much, hence why manufacturers are veering away from superchargers and adding turbos to everything
I really wish I could have the corner exiting feel of a supercharger with the sound of a turbocharger.
Wtf i learned more information in 4 minutes than an entire online course that costed $10.US and 1 week wtf thank u
We own both a supercharged and a turbocharged vehicle. Vastly prefer the supercharged one. Instant power from idle, just like having a bigger engine.
I don’t know shit about cars and you explained mostly everything in 4 minutes. Well done video
I want a super charger for my truck, it needs more boost 😂
Dont we all need more?
Mac versus PC, but light versus Miller lite - etc...
Thank you for making this video
Both systems are great, the problem with the turbo is to use the engine oil, this is critical and terrible.
Let me sit in the middle cause i have a vw golf 5 gt turbo*charged (this car is mostly European as i know but i haven't seen anything in US drop it down if you have. 1.4 tsi twincharged engine 170bhp) it still amaze me how it works and sounds especially the supercharger it sounds amazing 🔈🔉🔊👌🏼
In my country mk6 jettas come with the 1.4tsi twincharged engines.
As the owner of a Twincharged Golf... both. Both is good.
another difference is in NA and Supercharged engines the hottest the engine oil gets is around ~200°C while in a Turbo engine the engine oil can get to 400°C as it cools the exhaust gas driven
turbo. So all things being equal surely the Supercharged engine oil would be cleaner and less stressed over the oil change interval period.
That "whine" at 2:53 was so gooood.....
Super clear explanation. Thanks a lot!
This guy knows his stuff
Love the video. U got straight to the point and explained good ! 👍🏻
Perfect clarification. 😍 & my exact supercharged engine was shown in animation! Perfect haha
Coming from a 8 valve G60 to a 20 valve 225hp 1.8t with the same displacement size engine in the same car ,its wayyyy more fun with a turbo. been on both sides of the fence, turbo for me. was cheaper and more reliable too
Should have mentioned the effects on engine lifespan of a turbo vs a super.
I avoid turbos because I don't want to replace a worn out engine every 100,000 miles, the back pressure kills.
Just makes sense when you're trying to force more air in but creating back pressure from exhaust restrictions that it would create excessive wear on the engine.
you need to stop theory and go for practice dude...
But supercharged engines have to work harder to achieve the same power making it harder on the engine components.
I think the simplest way to translate what you said into layman speak, supercharger gives you more performance at low RPM and Turbocharger gives you more performance at mid-high rpm. Now this is obviously subject to another phenomena, exhaust volume. As your engine volume increases your exhaust volume/flow increases. So you may be able to get the turbo to spool up at lower RPM's in some instances encroaching on the supercharger... at the same time larger engines have more HP to spare to push a turbo so still it comes down to off the line power (like a drag or 0-60 times) vs power at speed (passing acceleration on the road). I think that Turbos serve the common motorist best and super chargers are more a drag strip option, but again as you change the engine size/composition, and usage you'll see how the two work with your power train change a bit.
IMO another negative for a turbo is the heat it makes under the hood. Very hot!!!
For someone who needs power in the city in a drag race like most of us, the supercharger is the choice. Just hit the gas and go, no lag no bs.
Just watched a video of two Mustangs, turbo and supercharged, the supercharged one kicked ass in all the tests.
"Your late night internet history search"😂😂😂😂😂 that was smooth and funny!!!!
Centrifugal: the best of both worlds
Though it may whine often.. My sc'd car never ceases to amaze me😌👌🤙
What about a hybrid of both of those, belt driven centrifugal unit, such as procharger?
Still is better than a traditional turbo
Both have their pros and cons. I believe its personal preference.
If have the choice of one... would definitely go turbo,love the sweet sophisticated noise it makes...just love it way too much 🥰🥰😍😍😍
Just to add that you only get that sound on high pressure turbos. Low pressure turbos don't make any discernible sound, such as those in diesel car engines. But high pressure turbos DO sound great, totally agree ! 🥰🥰
B8 S4, sweet car. Had one and loved it.
Most superchargers can literally just be bolted on lol.
Coming from experience with Turbos fuel efficiency is great up to the 3rd year of ownership. Due to the plumbing connecting it to the exhaust down pipes. The carbon build up causes a number issues causing check engine code (forgot the code) of Turbo OverBoost. Due to up of the carbon the internal veins lock up boost and horsepower is lost. Also, most think the system is light weight still have more tubing/pipe plumbing and brackets to add weight. If I would have a choice Super Charger is more reliable.
I run a f1-a procharger on my 1200rwhp 09 z06, let's just say it never disappoints.
And turbo engine can be gas savers if you drive them normally. Just wanted to throw that out there
Superchargers seem to be great at the lower rpms and quick accelerations, turbo has greater fuel efficiency and rule the higher rpm part of the power curve because they have LESS parasitic drag. Any time you put some resistance AFTER your exhaust manifold you are robbing SOME power from the engine. You are hoping that the power gained offsets the extra work you are imposing on the engine.
Superchargers are so much fun
I love the supercharger on my audi s4. I don't have to worry about heat soak and running my car after driving.
The instant power and response of the supercharger makes me prefer it over the turbo charger even knowing the disadvantage of it.
This is why I want one I have my GTI for my turbo fun but I want an S4 for that instant torque and blower whine
@@elihere1242 agreed.
@@Ethan007Hacks the engine just feels so much like a bigger V8 with the supercharger on it. I had a mazdaspeed6 prior to this and the turbo boost was apparent. And if I was sitting in hot traffic, I'd give it gas and it felt dead. The exact opposite with the supercharger.
@Samad Allah incorrect statement superchargers does heatsoak check your intake temps when running hard. I have a icetank in my srt6 to keep my intake temp around 40 degrees
Aw snap, nice typ44 action in the beginning!
I remember suck, squish, bang, blow from Sport Compact Car article back in the day.
Very easy to understand. Great job.
Late night internet search got me so bad 🤣🤣🤣🤣🤣🤣
2:57 that does not sound right: turbo easier to retrofit onto an engine. The turbo has lots of ducting that needs to be fit into the engine bay, and requires more engineering / calibration of parts to make it work well.
A SC on the other-hand is a compact unit that fits into the space that formerly held the intake manifold. The inter-cooler plumbing is a couple of smallish water lines which is more compact and easier to route.
Seems to me, the two main differences to consider are:
-turbo has slightly less parasitic load when compared to a modern twin-screw SC.
-SC naturally has zero lag / better throttle response. Turbo-lag can be greatly reduced, but takes some thought and tinkering.
The turbo seems to get the advantage when you are doing a big run of cars, while SC seems to have the advantage for individual upgrades.
It's always a tradeoff.
Superchargers can be geared to help more on low end grunt, supers have to aim more for mid-to-high end power.
Thanks, keep upload new ideas and new repairs. Thanks a lot
The difference is the price the cost for that part and say bye-bye to mpg but you’ll have a lot of fun that is guaranteed
This was very very good. Thank you
Excellent video dude!!!!
Those things you know but because you love them so much you still wanna here...
Just depends on the build and what you want to do with it. My 2.4CRV has a head w/manifold built in so a turbo would bolt directly to the Head. A little bit of Plumbing/fab for the intercooler. Run a new 3in cat exhaust Y'd off for dual 2.5in stock CRV Mufflers. For a quiet sleeper.
Hi @GT Godbear, I have a few questions for you. What's the configuration of the turbo inlet and outlet? Is it T3, T4 or V-band and at which A/R? Did you upgrade your fuel injectors for the turbo? Have your k24 CR-V boosted with Garrett turbo or Precision turbo? Did you put in an oil catch can? How many whp does your CR-V makes after the turbo setup?
@@TC926 T3 or T4
Really nice explanation, thanks for the video 💯👍
S5 450HP + 595 NM of instant compressor power😎 supercharges all the way!
S5's are slow af....what are you talkin abt....put an 'R' in front of the 'S' and now you're talking about something worthy of mentioning, but S5? come on, wake up.
@@farmanshaikh6405 This is a bit of a childish reaction, but I guess this is the internet so manners don't count.
I rather had an RS but to be honest I couldn't afford one. I do about 3.8 sec to 100km/ph with my S5 which is really fast for me 😊.
If you're car is faster, good for you👍
@@farmanshaikh6405 what you smoking the s5 v6 with 500 hp stage 2+ is brutal I have one I beat rs m everything
To end this debate we need to boost the same exact car and dyno/drag strip them both.
Doesn't mean anything if one is just faster need to track it hard for while see how heating up and changes in rpm and throttle effect the result.
Mighty Car Mods have done it, 2 identical miatas, 1 turbo 1 supercharger, check video it's very nice, they did alot of tests it's really a nice video
@@tusunakitsnay link plzzzz😭
“While these sound like your late night internet search” 🤣 🤣 I.. don’t know what you’re talking about..
I'm definitely a supercharger lover but that's more about the looks and instant torque. Not saying a turbocharger is torque less cause we all know there not but when buying a base kit the supercharger is gonna give you that instant torque where as the turbocharger is gonna give you that top end power
Why not both?
*faint explosion sound in the background*
Actually you can and it's relatively safe. Especially on a diesel. A turbo provides the low end torque and if you gun it, the supercharger kicks in. I would like to see BMW implement both turbo and supercharger on their M Series. If anyone can, it would be BMW.
if you have a twincharged engine you can have consistency and power and all around coolness
See that sounds backwards turbos are more complicated to put on caused because you have to change the intake system the exhaust system and much more. Compared to just putting a supercharger on and hooking it up to your Crank
How is retrofitting a roots style supercharger more complicated than a turbo? With a Turbo you have to drill oil ports, lay oil lines, install wastegates an blow off valves, etc.
With a supercharger you just need to isntall a mount (maybe custom weld one, or let weld by somebody), attach a pulley and its done.
Once someone has done all the R&D on a supercharger it easy, but not if you’re starting from scratch
Spinny wheels vs twisty shafts!
It depends on what you want it for, if your gonna use it as a daily driver I'd just go turbo, you don't need the instant torque
Turbo also have back pressure and product large amounts of heat . Plus all the piping and hardware can make installation a nightmare .
I love this video!!! Thanks man!
I get what you saying but watched 2:54 over and over lol 😆 love the supercharger
Damn kudos on this video Paul.
Which is better on the engine and which one last longer? I'm not the type of person that lies to myself like I need every bit of power😂 either upgrade is going to increase power but I love reliability at a affordable price.
How about the electronics required for each? Is one easier to merge with VW's CanBus? Thx.
I like both and would use either for a build. But I do like the supercharger sound more. It's got the better whistle sound imo. But they both have pros and cons. So it comes down to personal preference. So everyone is different and will like more than the other. Especially if ones cheaper and you can get a deal? Because cars with high HP are expensive asf. And building a muscle car still is expensive asf. But it's cheaper to build yourself. Plus you get way more choices
If you have a stick shift then turbo has instant power of you don't mind sacrificing the clutch. Rev it then drop it into 2nd gear at high rpm.
