How Twinchargers Work: Supercharger + Turbocharger
Вставка
- Опубліковано 12 вер 2024
- What is a twincharger? How does twincharging work? Twincharged engines incorporate both a turbocharger and a supercharger. The supercharger helps create boost at low RPM, while the turbocharger provides boost at high rpm. It's the best of both worlds, the benefit of low RPM boost and high RPM efficiency.

NEW VIDEO EVERY WEDNESDAY!
This vid was posted ~5+ years ago and I've been wondering about this very topic for even longer.
Thanks for this
Me too, just tonight I decided to find out what the difference between both is and then wondered "why not just use both?" And TAAADAAAAA!!!
its been 10 years and people still want to learn about it
I love the idea of a twincharger system. However, not a lot of OEM makers go this route due to complexity (VW had a 1.4 twincharger engine sold in Europe, but killed it due to high price and complexity). However, Volvo recently created a 2.0 Twincharger engine for their T6 trim...
Trades46 Indeed they did! 2015 Volvo S60 - Twincharged - Review & Test Drive
its actually pretty easy.... i mentioned above i did it recently on a porsche 924 2.0 liter. once you wrap your head around the plumbing of it easy to execute though requires programmable aftermarket ecu. the biggest issue with the system is finding the room under the bonnet to pull it of
Trades46 I drive said 1.4 twincharged engine, little thing is an absolute peach 😄

+Trades46 Another one of the few cars that used a twincharging system was the Lancia Delta S4 Group B car, in both Stradale (road model) and Evoluzione-II (competition-spec) versions.
After watching all of your videos on turbocharging/supercharging, variable geometry turbos seem like the best method of forced induction to me. And thanks a lot for all the videos! (aspiring automotive engineer here)
You make life so easy, thank you. (y)
I just Googled this topic because the T6 engine in my Volvo uses both and includes the Polestar Engineered mode. Thank you for explaining the interaction and benefits so clearly.
I know this one! Supercharger + Turbocharger = Erection!
Twin Turbo plus a Twin Supercharger=Bigger Erection
Captain Ghost twin turbo doesnt mean better. Becouse twin turbos works in differnet RPMs, one huge singel turbo is way better than twin turbos. Atleast more horsepower and tuning potensial.
Captain Ghost BMW 335i twin turbo, 305 horsepower, if you switch them with a singel turbo you can get 500-800horsepower becouse it can handle way higher boost of pressure.
MrChriz333 and this is why they are better especially if you can tune your supercharger to quickly spool that single turbo that you are more realistically going to get more power from
= this guy ...
Does this setup eliminate tubo lag?? Correct me if I'm wrong. The supercharger will take over in the initial stage of throttling (mid range RPM), therefore the turbo will have enough exhaust to feed from even before fully kicking in.
That's why Lancia did it with the 1986 Delta S4 Group B car. 0-60 in 2.7 seconds.
Hi, love the video. What would happen if you don't run the clutch set up and bypass valve?
Also would it cause damage to the supercharger if you didn't run them
I was thinking if running a Magnusson 2300 Heartbeat on my already turbocharged LS1
Than you for your help.
I
@@thanasikassi3095 You'd just be loosing power at higher rpm ranges to the Supercharger and technically you would have eliminated the Turbo's work
this setup looks very interesting, kinda wanna try it with my CA18

Seeing this video only one thing comes to mind: the monstrous Lancia Delta S4. A great example where twincharging is working amazing! As another guy asked, we would love to see a video explaining the difference between bov, dump pipe, screamer pipe and all this stuff!!!
I was hopping you were going to explain the advantages and disadvantages on a setup like this.
The only real disadvantage is cost and complexity.
I imagine it must be difficult to tune an engine with both a supercharger and a turbo. Years ago I know it was thought to be impossible, but these days more and more people seem to have perfected it
Ok but can we talk about how Hector is going to be running 3 Honda Civics with spoon engines. And on top of that, he just went into Harry's, and he ordered 3 T66 turbos, with NOS. And a Motec exhaust
F&F
I was just thinking if that’s a soon as I heard Hector👍🏽
I wish I could laugh react this

Was it hard to setup?
That thing the ultimate sleeper
Hey I want to twin charge mine what's the best steps to take?
I actually seen someone who did it to his Ford GT, but then when be dynoed his car I notice supercharger "Whine" then turbo, so basically from what I understand of this idea is you will never have turbo lag or lose throttle response, to be honest it sounds like a lot of work but it would be sick setup because you will not lose boost because "supercharger belt" might rip at high boost or get damaged,
P.S: great job and subbed
yep you get it sadly the supercharger has to drop off on the high end one to save its lifespan from wear and tear on top of constant usage giving heatwear but also i have heard if its on in the high rpm since superchargers start to bog it actually bogs the turbo somewhat as well
Your videos are well structured and you explain really well. Thank you
Can you do a vid on compound charging where the turbo feeds the supercharger? I don't understand the benefit of this.
Benefit is the turbo sees an effectively larger engine due to the already larger airflow created by the supercharger. So the turbo can be much larger. You need to think in pressure ratios though to get your head around it.
Im curious about that too.. I wonder if having a SC feed pressurized air into a turbo will help spool the turbo more on the low end before it gets exhaust gasses.. Its probably negligible but would be interesting to see how each configuration would compare
RaliTek has some videos on one of their projects that use this idea. Over boosting and parasitic loss are the main problems with it.
@@ryanbernard6550 i wouldnt necessarily say that i mean back in rally they used to use misfire systems that when you would brake would make the car misfire to backfeed exhaust pressure to spool the turbo up even off of throttle the only reason they dont use them anymore is it uses a lot of fuel i think as well as cutting the engines life in half but when its running it defiantly made a huge difference mainly in making cars like lan evo's really good at dog fighting in rally since you could brake and then dive into a corner straight sideways while slamming the throttle to the floor at over 90 miles a hour
@@dr.dylansgame5583 antilag is bad for trubochargers, especially older, lower tolerance turbos. Itll drastically decrease turbo life
From my understanding of forced induction.
I used to work for one of the first companies in Australia to cast turbo housings.
The twin scroll is hard to beat for simplicity and cost effectiveness.
Of course with engines in a V configuration twin turbo installations are hard to beat.
I was suprised that belt driven impeller type superchargers never took off in the OEM market.
I have watched all ur videos nearly on turbo/super chargers nd combustions nd it has been a really help
duddddde i love this dude, just found the cannel 20 min ago looking to understand what a turbo was and now i feel like an axpert on the diffrences of turbo and super charger and cuz of the other vids also know the different types of each lovin it
So I appreciate the time u spent to help everyone that's watched this
Just came here 9 years late to understand my volvo T6 engine. Great video!
Could you add a twin turbo with a supercharger? If so would it make none, some or a lot of power?
well that would depend mainly on setup if you had huge 57mm turbos it would make crazy power...all the supercharger is doing is making up for the turbo lag and giving you the low end grunt that turbos just cant do
It would make all the power... all of it.
Michael Budlong yup, stick with the single turbo because less parts means more reliable. 1 massive turbo can do as much as twin turbos because the supercharger removes the lag.
The Audi SQ7 TDI is a twin turbo with a supercharger
There is no point of using supercharger on twin turbo engine, the reason they make twin turbos is exactly the same as the supercharge a big turbo engine, and it is to eliminate the turbo lag! one turbo kicks in first and helps spin the othe turbo= elimination of big lag and get better throttle response! Hope that makes sense!
Thanks,
This explained the combination the best. We are getting the Volvo XC60 T6 which runs off this method.
What if in high RPM you never disconnect supercharger, 1. Is it possible both working together in high RPM?, 2. If last question is yes, is boost increase dramatically?, 3 what are advantages and disadvantage to use twin-charger at same time in high RPM? Great Video by the way
Lancia Delta S4
The turbo will re-compress the air coming from the supercharger. You don't need the supercharger on a clutch, and do not require a bypass valve. It's called compound boost. It's a very simple system.
Im 17 and got my first truck a 1998 Chevy Silverado with a V8 motor 3 day ago and I've been watching videos like this because I really don't know about cars and trucks. I feel like this video really help I'm making my decision on whether to put a supercharger or turbocharger on my truck thanks
Very nice vid man. TC must be experienced hardly anyone imagines how much kick it gives from the start. No turbo can give low end like sc.
Thank you for explaining it that was awesome thank you thank you so much man what I learned when you explain I learn a lot once again thank you thank you
Everyone explains twinchargers as supercharger 1st than turbo charger 2nd. When actually this is all relevant to the size (and efficiency) of the turbo and super charger (not to forget the pulley size on the supercharger) Theoretically one could have a turbo at low rpms and supercharger at high rpms depending on the size of each. Maybe a video demonstrating how to pick the right size turbo or supercharger (or twincharger) depending on engine displacement would be a good additional video. Don't forget twin turbos and twin superchargers. (pulley sizing probably won't be a bad idea either) Thanks again.
this video helped me a lot with a presentation for school!
Oh my ... I love this stuff! Registercharging, Dual charger, twostage turbo, ...
... and all the nice things we can do when this is further made more complex, miller cycle always comes to my mind (because it is the logic net step after downsizing and optimization of detailery and stuff), hybrid also, and those two, with a halfway-complex, halfway-efficiently used boosting/recovery-system, with an electrically pampered ICE, the improvements in efficiency that are literally lying in front of our feet are only exceeded in their impressivity by no one really going all the way.
All the cool things that came into greater series production have been lying in drawers since close to forever. Stratified injection? Old, thirties! Variable valvelift and duration? Twenties! Turbochargers with, say, variable compressors? At least 20 years old. Electrically assisted turbochargers? Were "the next big thing to come!" ever since downsizing became the industrie's standard.
Anyway - I love your videos, because, it seems, you are a great narrator and know your stuff. I haven't heard anything that was wrong so far, nothing that was harder to understand than it needed to be.
I must admit, I sometimes chose 1.25 speed at youtube, I would actually like you to talk a little bit faster ... but then, again, who am I to demand anything?
... one of my favourite channels - keep doing this, stay true to yourself and ... and ....... uh ....... have a nice day?
Yeah. It in fact IS a nice day.
I have always been fascinated by this but I wonder if the re-engagement or the clutch is going to unsettle the car when you lift off and the car is coasting. Does the clutch engage smoothly or is it more of an on/off switch. If you are decelerating and this things engages mid corner I imagine it would be very unpleasant situation
On off switch. I have a twincharged 1.4 tsi. It engages based on throttle pedal position, so you just learn it with time. You can feel when it kicks in: much more torque, acceleration and of course, noise!
And no, there's no issue with it being an on off switch.
I suppose you could use a viscous coupling for a smoother take up, I'm thinking of making my own system, I've got a 5 series bmw with engine problems and if that thing has to come out I'm getting frisky with it 😂
Bro, I always think which is better but you just teach me that both will be at the best if both are combined. Thanks bro
The glory i see from this is you have a efficiently mode you can do where you can simply just not activate the super and you can drive somewhat efficiently in low rpm
I’ve been doing a project on how this works all yeah I’m very happy I found this video and disappointed that it took this long to find
Thanks for the forums your explanations are brilliant, cheers from Queensland Australia
A number of piston airplane engines used in the 1940s and 50s have both a blower and a turbo. However the turbo is normally used for cruising at high altitudes, 15,000ft or higher. It’s only used at altitudes below 10,000ft for depressurization of the cabin prior to landing.
Prime Movers (what we would call engines) in diesel locomotives had super and turbochargers for a few years.
Also I run atmosphere => Turbo => Supercharger (SC14 roots type) => intercooler => TB => intake manifold, no bypass valve needed with a a/c clutch type s/c (just free spins)
How would you go about adding a Turbo charger to an already supercharged system
You definitely need to tune it if that's the case
From what I've read you mostly install the turbo (which can be obnoxiously large) in series, and then have the wastegate measure the boost after the supercharger ( that's pretty important as the boost of the turbo will be compounded with the blower's boost rather than just added to it)
I wish I could experience this kind of set-up. Looks awesome.
Could you do twin turbos and a supercharger
Yes you can actually.
Loginwithlogan 3 i got a idea what about 8 twin turbos in 1 car that car will burn the tracks
Loginwithlogan 3 look at the ford gt that broke the land speed record. They have a twin turbo supercharged nitrous v8
Alex Clemente actually that is just TT. They took the stock supercharger off when they started the build. And I'm not too sure about the nitrous either
Yes but only with a v13 engine and water methanol in your morning coffee
Can you make a video explaining twinchargers in more detail? From what I've read, you've only explained one type of twincharged setup. There are series and parallel configurations. From my research, I've discovered there are 2 routes you can take regarding the series configuration as well. The one you explained here makes use of a bypass value and a clutch to disengage the supercharger which increases the efficiency of the induction system. However you can choose to keep the supercharger running and feeding air into the turbocharger inlet yielding elevated intake pressures. The other series configuration which exists is where no bypass system is used and both compressors are continuously running. Using this configuration results in compounded boost pressure which means the pressure of each compressor is multiplied not added to each other. Here the turbocharger is feeding the inlet of the supercharger. Also I've seen twin turbos feeding a supercharger as well but I'm not sure if you can do that the other way and have a supercharger feed twin turbos. A parallel configuration is when both turbo and supercharger are connected directly to the intake manifold. A bypass or diverted valve is used to prevent the supercharger from blowing backwards through the turbocharger.
You guys might get a kick out of some of the aircraft engines used in WW2, like the turbo compound Wright 3350, plus most others had either centrifugal superchargers, turbosuperchargers, or both, mostly to "normalize" the thin air at high altitude. But the TC 3350 had three turbos which had shafts that added the power right back to the crank for efficiency. The last dying throes of the large recips.
I haven't heard of this on a Honda d-series engine, but definitely going to try it if I can get the money going. Expensive, but I'm a die hard d-series guy all day
Very well put my guy
Either I'm missing something or your flow diagram has a problem, specifically the location of the bypass valve. In the diagram boosted charge from the supercharger connects to the atmosphere during mid RPM. Under such conditions some of the boosted charge will flow backward in the intake. In twincharging I thought it was easier to have the intake flow to the turbo first then to the supercharger. Air will flow through the turbo as it does below the boost threshold and compressed by the supercharger. Above the boost threshold boosted air will be delivered to the supercharger. If one wanted to bypass the supercharger at some point the bypass valve would be located between the turbo outlet and the supercharger inlet.
So Quick but so intuitive
I have a Chrysler 300C with the 5.7 HEMI. Been toying with the idea of either a supercharger or turbocharger. Wondering what would be needed to build a twincharger instead...
Thank you very much! Very informative and the visuals really helped me understand
Should revisit this topic with a compounding twin charged setup
There is an air Force mustang out there where they put LCD screens in itfor the windows I believe but it has a supercharger on each the valve cover 9r over and the turbo on each side so twin supercharged in twin turbo and they had some kind of hud technology to make it look like a jet the seats at in the center and it was able to be driven gas brake and steering all in a joystick like a fighter jet has it's awesome
Thank you! I was hoping you'd make a video with both chargers!
i like the juice n boost turbo combo. the blower is 24/7. the turbo can be mitigated by normal driving. so...when you feel the need...the need for speed...you can romp the throttle
..enjoy the turbo.if you cant tolerate the turbo lag for whatever reason ( supercar pulls up next to you at the light)... you can engage an electric opener for a nitrous system ( juice)... dial in 25/ 75...100 horsepower...whatever...by jetting...purge and arm all within a few seconds...now you have the off the line nitrous hit...and then the turbo will take over...and after you say a quick prayer...you can laugh at the Lamborghini in the rearview.
Do you have a video on compound charging (turbo feeding supercharger)?
Few questions. Why not, instead of a clutch to the supercharger, simply have an opening for air above the compressor screws? Turning the supercharger isn't what robs power, the act of compressing air does. By preventing the air from compressing, the only power draw is friction at the bearings and the rotating mass of its internals (which is minimal).
Would this be doable with a roots-type or twin screw type supercharger?
Also what would happen if you simply had the boost from the turbo go through the supercharger instead of being bypassed around it? if the supercharger was built so that it could handle the extra pressure would that work or is there something I'm missing that would cause an issue?
Wolfly Loyals.... Compounded twin charged setup is what you are asking about.... Lancia Delta S4 did that setup back in the 80's Group B rally car... Also EvoMadMac did this on his Evo5..search youtube for that beast too... His Evo makes 800 ftlb torque and 800 Hp at 6200 rpm...
Awesome thanks for the response
yes it would. There is a guy that has 2 builds that are quite famous on youtube 1 vehicle is a twin roots type supercharged chevy c10 and the other is a twin turbo supercharged big block camaro on nitrous. The turbos feed into the supercharger. The entire setup is absolutely crazy.
Would it be possible to use a variable geometry turbo twin charged with a supercharger?
Lancia has a twin charged rally car with 800hp....Chris Harris from /Drive has a video on it. Not sure if you're a fan but MAN I love that channel. Also good explanation as well. I've been avoiding your videos because I'll spend entirely too much time watching them instead of going outside XD. Good job man!!! Again congrats on the STi!
Thanks, glad you enjoy the channel. Loving the STi!
Is it everything they say? Is it like sleeping with that one Movie star that you know you'll never be with? LOL! You know what I mean!
These videos are really well done!!
nicely explained
im looking at vectra vxr for my next car, these come with a twin scroll turbo meaning boost comes in early and a remap will see 400lb ft of torque!, the downside is that the turbo runs out of steam VERY early and the power drops dramatically.
my idea was to pair a centrifugal supercharger (more rpm = more boost) with the turbo to give a huge power band. the thurbo gives low/mid rpm power and the supercharger gives great high rpm torque (and hence hp)
do you think thats feasable?
great explanation... i understood it perfectly
Bro a roots blower or a gmc supercharger (this is important) the blower is positive displacement not like a procharger or turbo ... The suoercharger made a 2 stroke diesel work and they had turbos for more power. The blower made the engine function.
To me, it is the perfect set-up for any internal combustion engine!
Could you have a twin turbo and a supercharger ? Would it work the same as a single turbo twin charger setup (as in the boost running thru the supercharger then thru both turbos) just wondering, I dont think it would be very useful but very cool if it's possible
This is the way VW 1.4 TSI was set up. Good for steady boost and inherently fail-safe, as the supercharger will limit the air flow according to engine RPM. Lancia S4 group B rally car did it the other way around. They had the turbo feeding the supercharger. Not as simple for a steady boost or as fail-safe, but allows really fast and high boost as the pressure ratios are multiplied.
As for the reduced efficiency during transition, it's true multiplying 70% efficiency of a turbo with 70% efficiency of a supercharger doesn't yield a nice number, BUT either compressor needs to do a lot less work which makes up for a lot in the overall energy consumption.
Amazing
Great series of vids thanks
Can you do a video explaining Bypass Valves and how they are different from waste gates and Blow Off Valves?
How does the bypass valve work? Does it open with pressure or is it electronically opened? (like a modern throttlebody).
Amazing explanation. By the way, what it would be the cost of not having the clutch to deactivate the SC? Since lets say, the turbo at full boost with the bypass open the SC wouldn't fight to create positive pressure since the turbo would be doing that. It will have some loss but not compared with the bypass closed.
Other question is would the SC help the Turbo to Spool?
Last but not least is there a bypass butterfly valve that opens when delivering boost to an actuator, like a mechanical way to open the valve when sees boost, or is only electronic?
There are also twin charging setup where the charged air from the turbocharger goes into the supercharger and is compounded. Opposite of your diagram.
I want one of these in my 5.4L Lincoln Navigator
Hey just wanted to ask, is there a way to create two air intake valves so one goes to the supercharger an the other to the turbocharger and are both compressed, then meet up in a large intake manifold that then takes this compressed air to the engine?
the supercharger can not be before the turbo it would restrict boost .. its turbo first then supercharger in a roots set up.. supercharger help spool up turbo at low and by mid supercharger is compressing the turbos boost even further in the intake..
Excellent video!
Always loved the concept of twincharging but I know none of the science behind this so help me if my reasoning is off
Is this setup the most effective use of the supercharger? Air from S/C hits the turbine of the T/C, then turns a hard right to get to the engine. Sounds very restrictive.
The perfect setup (in my mind) would be a "y" pipe right before the Throttle Body. And it has to be the lower case "y" with T/C connected to the straight side facing the TB and S/C connected to a Blow Off Valve, then to the branched side of the "y". There would be a flange where the "y" intersects which closes off the T/C side during S/C operation. Guess a BOV would be needed on the T/C side for good measure. As the amount of boost on the T/C side starts to meet the S/C or it meets a certain RPM (however it works), the flange begins to close off the S/C. The S/C should disengage exactly when (preferably right before) the flange completely closes expelling its leftover boost via BOV. Take your foot off the pedal, meet the same requirements but in reverse, and the flange swings back the other way.
Would this be a functional system?
Lancia Delta S4 rally car had this in 1986, 0-60 in 2,3/2.4 sec on gravel, up to 1000hp in test mode, between 550-750 hp in race mode (gravel, street)
This system is very much applicable into a Weber 40 carburated beetle... As long as the w40 is placed in the middle of the intake pipe, of course...
Engineering Explained Is it possible to have the turbo and supercharger on separate intakes, and then combine them after the compressors to feed the engine? It seems that each would perform to its maximum that way.
Chad Barkley you can run the super charger directly through the turbo because the super will not heat the air as greatly as a turbo mostly because the turbo is run off exhaust gas which can be anywhere between 1100 and 2000 degrees so the turbo will be hotter by nature. this explanation is just of a more efficient design
I could be totally wrong but wouldn't a hybrid turbocharger be a better, simpler route? Because then you'd generate boost before the engine even revs up by spinning up the turbo with the electric motor, and also decrease pressure on the exhaust side. I don't know maybe I'm wrong but it would seem to be a good concept
Great video. The twincharger seems good but I feel reliability would be an issue. I have noticed that naturally aspirated engines with high power (Example Honda K20) makes very good power when turbocharged at relatively low boost. If one were to use an engine (Naturally aspirated) with high volumetric efficiency hence high specific output somewhere around 100hp/litre and then turbocharge it using a small low boost turbo, wouldn't this eliminate turbo lag and improve power throughout the rev range?
I looked through the comments and didn’t see my question so here it is
Can you skip the bypass before the supercharger and just run both the super and turbo at the same time 100% of the time? As in put them in line one after the other with no bypass stuff happening
I've heard supercharged or turbocharged engines need different lengths connecting rods than each other/regular intake engines due to compression issues. How much of that is true and what else might some people not realize needs change when adding performance parts to an engine? Would you mind doing a video on that?
Dragoon876 changing connecting rods wouldn't change compression. Changing compression is mainly pistons and cylinder heads
and more over the regular rules dont apply you would have to start from the ground up with an engine that was built with the idea of running loads of boost and with that alot of it
Sometimes changing connecting rod can change the cr, if you put a shorter rod in a engine the piston wouldn't be able to reach to the top of the block deck and the cr will be lower. It happens on the old Nissan L series.
Thank you very much
This is amazing thanks for your hard work !
I have a question you could explain, more in depth. About turbo impeller size and spec vs the same in your supercharger and how to spec them per liter of engine.
Why would the supercharger disengage? From what I hear, twinscrew superchargers provide boost all the way through the rev range. So would it not be better to keep it going throughout?
Also, I didn't know clutched superchargers were all that common in the first place.
Awesome! you did one! thanks! I was the guy who bugged you about it :/ sorry about that, thanks again! awesome insight yet again!
Haha you're not the only one, glad you enjoyed it! If enough people prod me about a subject, I eventually give in. :)
What if you had 2 separate air intakes. One for the supercharger and one for turbocharger and combine the airflows of each right before the throttle body? I know at high rpm some power would be lost to the supercharger but is it really an issue? I mean you're still making crazy power no?
Could I simply use a reed valve in both the SC intake & turbo intake? They would prioritize opening on which has the higher pressure & the other will close.
Turbochargers are not as reliable as superchargers (not trying to trigger anyone). Its a true fact, Even though superchargers burn more fuel.
i should have put this comment on the turbochargers vs supercharges video...
lmao, very wrong video XD
Isn't that mainly a torque and heat issue?
Hello.
Sorry that I am bothering you but could you explain if it is possible to Turbocharge an Supercharger.
What I have in my head is that air can go through the Turbo at low Rpm without restriction and Supercharger would compress air and give boost.
But at high Rpm Turbo would give Boost and Super Charger would make that boost even bigger.
So in that case you could use small Turbo that would spool up fast and there would be a lots of boost at mid Rpm.
Would that actually work?
Thanks any way and i love your videos and watched every one of them.
You are awesome!!
I think I know what you are thinking of, and that is not what a supercharger is designed to do. A supercharger is designed to work on -outside air-, not recirculated exhaust. What you seem to be talking about is internal compression, and that is actually what a turbo does when spooling up; it takes exhaust gas and depending on its design, either pushes that air to either faster speed or higher pressure back into the manifold where it mixes with fuel. A turbocharger and supercharger do similar things to different sources of air, so what you're describing is redundant. See the video on twin turbos.
Thanks bro real help
Should the bypass valve be at the top of your diagram at the entry to the supercharger?
How does the boost curve compare to compound turbo chargers?
Will it only work with a single turbo? Or you can also have a twin charger using a compound turbo + supercharger?
