Can a car be turbocharged and supercharged at the same time?

In short, no. A turbocharger and supercharger are both designed to pressurize the air and/or air fuel mixture, going into the intake manifold. A turbo is powered by exhaust gases, and a supercharger (blower) is belt driven, but the end result is pressure at the manifold, instead of vacuum. Though it may be physically possible to attach the two to the same manifold, they would actually work against each other. A turbo putting out, say 6 pounds of boost, would also be pushing against the blower (for the sake of argument putting out 6 pounds) nullifying it. Either one is enough to provide more than enough manifold pressure by itself.

Well, this Holden Torana is.

General Motors has been doing this with their 71 and 92 series V-Bank diesels for over 25 years (Marine Intermittent Duty). They are 2 cycle diesels that run normally aspirated with a blower. The turbos were added to bypass the blower at the higher RPM range via a wastegate. As Maximum_Reality has shown, it CAN be done with a car also, but the question remains: SHOULD it be done with a car ? <checks wallet for gas money........oops, spent it all on turbos and blower....no money for gas>

it is actually possible. and it has been done in the past. if you do a search on google for rally "group B". or look for the Lancia Delta rally car. they took the 1.8 L 4cyl engine and turbocharged and supercharged it. they were able to crank out over 500hp. It was able to get to 60mph in 2.5 seconds on gravle. they were shortly banned beacaus the cars were "too fast to race" the drivers had a hard time keeping them on the road. you can find video footage on google video and there is a movie about them called too fast to race. really good movie. hope this answers your question.

A guy that used to work with me, claimed that he had done that to his car. Ask him to bring it to work. He showed up the next day and said that he sold it that morning.... Nice pic, crazy

Yes it can be done and there are advantages to doing so. Just ask VW, theyve done it to their golf on a 1.4 liter engine. I suspect the reason is one of fuel efficeincy without the lag of a turbo system. That is, turbo=more effient (generally) and supercharger= more responsive down low. Mix the two together and you get a responsive small literage motor with decent hp up top. They switch their supercharger off once above about 3500rpm to avoid excess fuel consumption...and by that pint, the turbo is making the required boost anyway.

the supercharger is usely intake side an the turbo is on the exhaust side super charger forces air in the turbo forces air out add nos an you go fast ! better watch the tac'

Actually, Having a supercharged-Turbocharged car can be very effecetive as superchargers thend to produce boost almost instantaneously as its driven from the engine and once the turbo is upto speed (producing equal boost) the supercharger can be switched off thus removing any lag in the system. This will deliver low end response and torque whilst the turbo deliveres the power at the high end.
-
yes it can. You can but on a supercharger and a turbocharger on a car but it a lot of work but it is worth it. It takes all the pros and cons always from turbochargers and superchargers.

You can turbocharge and supercharge a car, as the Zenvo ST1 have proven. With a 7.0 litre V8 engine, which has a root supercharger and also a exhaust powered turbocharger. Not quite sure how it is all put together but i'm very interested in it. It is now out of the prototype stage and is being put into production. With 1,104bhp, its extremely close to the Bugatti Veyron and Koenigsegg CCXR Check it out at www.zenvoautomotive.com/

Yes it can, the only one I can actually think of right now is the VW Golf GT, it has a 1.4 turbo & supercharged engine..... it's as rough as bollocks!

Yes. There are significant issues however with doing it. The engine uses horsepower to run a Supercharger (parasitic drag loss) however a Turbocharger uses spent exhaust gases. You can force induce an engine with a supercharger then recycle the power out of the exhaust with a set of turbos, however you would need a very highly adaptive computer, a large and effective fuel system, and you would need a motor with precise internals and high end parts. Your bypass for boost would have work in conjunction with your supercharger and turbochargers. Essentially you would run a speed density system. Big stuff 3 or f.a.s.t. system. You would have a very serious vacuum schematic also.

Why all the work, just get a Bugatti - darn fast!
