but why?! unless you are going to stroke the engine and have a larger displacement the twin turbo idea isn't to much of an advantage for the amount of work put into it. (i'll explain more later, i'm off to class)

Logic tells me no, but .... gosh that idea is just HOTT!!

an engine with 300cfm (180cid) can benifit from a twin turbo system. Our engines are only 163cid (cubic inch displacement) and the advantage is only slightly better. In the long run you have slightly less turbo lag and top-end boost performance. Great intuiative idea .. but not justifiable unless you just "want" to do it.

the first turbo was small to create boost down low, say 2,000rpm, and taper off at 4k and the other would be bigger and spool up around 4k and tapper off at redline.
BMW just did this with a 5-series diesel engine in Europe and it gets something crazy like 500ft-lbs torque from 2,000 to redline!
