I know it might sound stupid, but is it possible to do a twin turbo setup, with one smaller turbo actuating a second Larger turbo? Has anyone ever done this, seen it done, just curious about this sort of setup. Logically it would allow a small engine to be sporting a freaking huge turbo!


thanks

This has been ask more time then I care to remember, do a search and see for you self.

 

Sorry, and thanks!

 

Saw a Dodge Charger at SEMA this year with twin turbos and a supercharger. Wasn't completed yet so I don't know how it's going to perform but same concept. Supercharger should provide low end boost torque and twin turbo's for the high end power.

 

Did it run or is it the typical show piece that looks sweet but really is a fake?

 

Looked like they had big plans for it but it wasn't finished yet. The turbos fed a FMIC and which exited the top. It didn't have the tube from the top of the FMIC to the supercharger intakes you see. Dunno but it looked cool.

 

ehh the supercharger will limit peak power but ill give you torque off the line, a straight up twin turbo would be less complex and ultimatley faster at the cost of a little driveability and low end power

 

all of those ideas are gay

 

heres a non gay idea from bmws diesel department.



comes with none of the downsides of supra/rx7/subaru TT setups, and works seamlessly. only thing is, might be trickyish to home engineer due to the flap on the outlet of the larger one. still, could definitely be done!

I believe hes talking about a compound turbo... ATS makes them for turbo diesels.

Compound turbo not Twin turbo...
