Can you Turbo AND Supercharge a car at the same time?

Answer 1

Yes, it can be done. It's usually done in high Hp applications where a large turbo with lots of turbo lag is used. The supercharger is then used to provide low end torque and help spin up the turbo.

Answer 2

BMW doesn't super/turbo their M series because they don't like the lag associated with turbos. Even though they can minimize it, they still like N/A. They've done a few turbo cars in the past, though. The 70's 2002 had a turbo version that's quite rare and valuable. They also turbo'ed the euro 745i back in the 80's. More recently, they turbo'ed the 335i. Of course, they have turbo diesels all throughout. Your friend's wrong. While a Z06 or ZR1 would destroy an M5, your average Mustang or Camaro won't stand a chance. Most M cars aren't set up to be turbo'ed. Their compression ratio is too high, for starters. But it can be done, in most cases by simply replacing the pistons and headgasket (which you need to do anyway). It'd be about $10k by the time you're done, though.

Answer 3

Yes it is possible, just not practical. There really is no reason to do both. As stated it has been done on diesels for years. It takes roughly 50 hp to spin a blower at wide open throttle on a GM 6-71 diesel (2100rpm). I believe it was Johnson and Towers that made the first blower bypass system. At a pre determined rpm the blower would be disengaged from the system and the turbo would be feeding air to the engine. This gave an immediate 50 hp gain by removing the parasitic loses of the blower.

Answer 4

The new volkswagen golf GT has a turbocharger and supercharger... 170 bhp and 170 lb ft from a 1.4L. Thats the advantage. However, a better option would be twin turbos, there is virtually no turbo lag and you get a smooth power delivery. Many cars use this, Skylines, 911s, Lotus Carltons etc.

Answer 5

You could but why spend that kind of dough? Check out some big-rig diesels -- many Detroit Diesels have a turbo mounted atop the supercharger.

Answer 6

unlike what dodgeman said it can be done and has been done on big diesels for years,your only issue with a car engine is space and dollars,you would need some pretty serious upgrading of the drive train or it may self destruct
good luck

Answer 7

I can't say I remember that being done. If you wanted more air, then you could change the pully and spin the supercharger up a little faster.

Answer 8

YES, BUT IT WOULD BE MORE BENEFICIAL
POWER AND RELIABILITY-WISE
TO SPEND EQUAL $$$ ON
either
A BETTER TURBO

or

BLOWER SETUP...

Answer 9

It is feasible but not efficient. One or the other can serve the same function and same result if properly designed.

Answer 10

I guess you could with enough plumbing and hardware, but you can only run SO much boost pressure, and either one will produce enough boost, so it would be pointless to do it.
