    A lot. I would guess at 8000rpm with a stock pump 150 gpm. Oh, wait you mean supercharger, I only saw the word pump. Maybe 200 cfm at 8000 rpm stock.

    I'm thinking more like 300 CFM. 1500 CC at 8000 RPM at 100% volumetric efficiency = 212 CFM. Assuming these motors make 160 HP with no SC, then the SC has to add approx 1.34 times as much air to get to 215 HP, add in losses, and I get about 300 CFM. Sound right?

    OK. i was gauging it by the time I put my hand in front of the 4 inch hose while the ski was idling. But if you want to break math out we can go there too.
