Call Kim at K&T. My dad and I saw a couple RZRs with K&T turbos on them at sand mountain UT, and they were hella fast. They were walking all over low mod banshees and 450s on the face. They were running about 15-20 psi if i recall correctly? (Don't quote me I don't remember for sure) But K&T could push you in the right direction I'm sure. I am not claiming to know about turbos other than the one on our powerstroke, but give your idea a shot! Without trial and error there would be no innovation.
