BIG turbo, BIG question !??

please make the pics viewable to all :-( I know webshots and photo bucket are good, but I dont have the interweb at home and my work has those image hosting sites blocked cause they think people look at porn.

I think the best way to do that whole setup is to run the exhaust through the holset and then through the mitsus. Have the boost from the mitsus go into the compressor intake on the holset and route the compressor output to the intake manifold.

There is more energy in the exhaust than in the boost.


also since you probably dont care much about the holset turbo maybe put a nitrous/gas feed and a spark plug right before the holset exhaust and use that to spool it, people have done this before and it works although it tears up the turbo after a while

word of caution on the hose connector you are using on the holset, if its the type of hose im thinking (thickidh rubber like material) itll start to balloon over 5-7 psi and is not meant for pressue just intake hose connectors. i only say this because i bought some of taht same hose at a turbo truck shop i frequent and they said i shouldnt use it on the boosted side just intake. so unless its reinforced silicone, i cant tell from the pix, i would try finding a better suited hose connector

my project car got pushed down on the priorty list as i just spent a few k$ in the last 3 weeks remodeling my new place.. wont jump back on it for awhile now since ive been focusing on that

I think that the boost from the two mitsus should go into the turbine of the Racoon Eater.
If the exhaust outlets of the mitsus feed the big turbine, i dont think it will even turn the damn thing... exhaust is still just the same amount of exhaust even if its went through 12 turbos, it doesnt increase in volume, but the boost would.

I can see why it would work good to have the boost go into the inlet of another big ass turbo, but in this case... the turbo would be spinning as fast as a worn out 12 volt drill! I dont think it will work like this. my .02

Compound setups like this work great on diesels, where you can run insane boost pressure without having to worry about detonation. Here's a thread which shows a setup kind of like yours, but on a diesel engine.
Twin Turbo WTF???

On your setup it looks like the twin mitsus would spool, but the bigger turbo would likely would not spool. Being downstream of the the mitsu turbos, there probably will not be enough energy left in the exhuast stream to spin up the turbine of the big turbo. If the big turbo did spool, and your boost pressures consequently went super huge, your pressure numbers in your exhuast manifold would go nuts, and you'd probably overspin the mitsubishi turbos something fierce since they super high pressure exhaust would have to go through them to reach the larger turbo.
