Twincharged EVO

Yes, that's right, I said it. Apparently, someone out in CO came up with the scheme to twincharge (supercharge + turbocharge) a Mitsubishi EVO. There's a lengthy discussion going on about it, and he's quite serious.

That is very interesting. Kinda funny the other day I was thinking if that would be possible on my Civic. I thought about STS's remote turbo system, and then I though it would be cool to throw on a Jackson Racing SC. Imagine the HP capabilities. But then again, the flaws would be numerous. I don't know. Would something like that even be possible for the Civic? Or any other car for that matter? L8...

So...the supercharger is used to help reduce turbo lag?

I wanna see what the dyno sheet for that car when it's done!!!

Supposedly, the owner is looking for a 9 second quarter mile car, which is quite the feat at like 5000 ft. elevation he's at....dunno what that would be at sealevel, ask Mr. Luos.... :)

He's using the supercharger to spool up the turbo by fooling it into thinking the engine is of a higher displacement....that's what I drew from reading the threads. I still want some turboheads' opinions on this board, and I'm still doubting its effectiveness. How will the fuel management system acount for both a supercarger and turbocharger....that would be quite the interesting map. and at what point does the boost switch entirely over to the turbocharger, which will be spooling faster than the belt-driven supercharger? Wouldnt the supercharger at some point begin to act as a restriction?

spools the turbo faster because the s/c makes larger exhaust volume at low rpms.

you just have to run rich everywhere lol.

Saw another car with that set up idea in an issue of SCC about a year or two ago.

i never though that you could do both but you learn something new everyday. He would probably need a computer in there to shut the sc off once the tc spools up. If in fact the sc would be a restriction at higher RPMs but i'm just assuming from logical thinking i don't know alot about the internal parts of cars.

I'm betting he'll blow then engine around 500 miles.

He could of just went out and spent the extra money on a dual ball bearing turbocharger....... What a waste of time and money

kick ass fabercation though
