I'm in the middle of starting to build a crank driven centrifugal supercharge motor for some local No Prep racing next year, hopefully luck
The motor will be a BB wedge Koleno block with B1-MC heads, 4.5 bore with 4.375 stroke, the Vorteck V30-123A super charger is capable of 40+ lbs. boost and 4000 CFM.
I want to try racing it on E85 and i have no idea on what mechanical compression ratio to make it have to start with help
Any and all suggestions will be greatly appreciated up bow
