View Full Version : Turbo and supercharger question.

01-25-2006, 10:01 PM
This is a crazy question, that some of us came up with sitting around the shop tonight. What would happen, or is it possible, to hook the outlet from the supercharger to the inlet of the Turbo and then into the motor??? Just something to think about!!

Too much plumbing, incressed lag. How would you fuel it?

ive actually seen a turbo feeding into a roots type blower before.... as well as an older car that was featured in popular hot rodding a while ago that had 2 roots type blowers and twin turbos. i dont really think the gains you would see are worth the work necessary to make it run well, but its a pretty cool idea.

and i THINK that some firetrucks have something like that...

I believe the old 2-stroke Detroit Diesel's have a similar setup.

The only advantage I could see is cooler air spooling up the turbo. I'm not a brainiac so I don't know. Sounds lke something a bunch of drunkin gear heads would discuss at the local watering hole. heheh

More shafts, more belts, more mass, more plumbing = more parasitic loss, lowered efficiency. Pump gas can only handle so much and you can go beyond that with any single form of forced induction.

Kinda along the same line, but Volkswagen is experimenting with a supercharger/turbo setup for the new Jetta's. The supercharger works up to like 3000 rpm and then it switches to the turbo. The supercharger will have a clutch like an A/C on it.

No reason to do this on a gas engine. This is done on Detroit diesels but diesels do not care how much you force feed them, the more the better. What you have on the Detroit is the turbos force feed the roots type blower.

This is what happens, I think there set up is turbos feeding superchargers.

Anthony -
I have to say nice car and very cool videos. What rpm was that running on the dyno? I couldn't read the numbers off of the dyno sheet. The glowing header was a nice touch too.

Wish it was mine, settling for turbo only and no paint at this point :) . From his site:

Max. 578Hp at 6300rpm, over 500Hp from 5200 to 7700rpm

Max. 706Nm at 4900rpm, over 600Nm from 4300 to 6600rpm

706Nm = 520 ft lbs of torque, 600 = 442. Not too bad for a 4 cylinder.

I'm unsure what rpm on the dyno, seemed at or near redline.

just run the trubo into the back of the SC! as long as the SC can take to presure you should be fine!!!


PS you may want to make the bypass vevle bigger and bypasss the SC once a set boot is reached but its not needed! all the SC is doing is moving compressed air rather than air a atmaspheric presure!
