I have read quite a bit about running two turbochargers in series to increase the pressure ratio, but I have no hands on experience with this concept, I'm hoping someone might be able to help me.
I'm building an EX500 Kawasaki landspeed bike, methanol fueled, I hope to make about 200 HP on the wheel. This is a two cylinder, four valve motor, 498cc displacement. (upgraded of course to handle the power level.)
I need quite a bit of boost pressure to achieve these power levels, and I can't easily find a turbocharger small enough that has a high enough pressure ratio to achieve what I'm trying to do...
Does anyone have any knowledge regarding compounding turbos, or can anyone recommend a turbocharger that will support a pressure ratio of about 4.0-4.2, and flow about 400 CFM?
