hey guys, im about to go in to haeve my vaccum leak fixed on one of my lines for my secondary turbo, and im wondering if i should go twin turbo or not? im mainly a canyon racer, and im thinking that twin will be more predictable on the moutain, but i would like to know the negitives. more heat created? less reliablilty? tell me all the bad things about making the stock seqentials twin turbos. thanks much

russell

Look through the pinned topic and it will explain everything involved. Also a few pros and cons on it too. Also take a look here:

I'm planning the switch shortly myself.

Yep...like 400 rpms "later". Non-sequential lag isn't that bad. FWIW, If your worried about 400 rpms...you should have bought a V8

I know this is begining to get off topic, but what about twin turbos. Would there be any benifit to having each turbo on an individual rotor. I know you would have to do some crazy throttle body work but would there be any sort of gain.

No custom throttle body work needed. IGY had a true twin turbo setup on his car with the stock throttle body. Made good power too
