Rotrex C30-94 vs C38-81 vs C30-94P
Hey guys, I’m looking to get some more power out of my FA20.
Right now I’m running a Rotrex C30-94 with the small 90mm pulley from the KW kit (315 HP at the crank to 6900 rpm and max 14 psi) , but I’m thinking of switching to either a Rotrex C38-81 or the newer C30-94P (the “Performance” version).  Just wondering, what kind of power difference would there be between the C30-94 and the C38-81 on 94 octane with small pulley (90mm), and what’s the max boost the C38-81 can make, at what RPM, and with which pulley? If anyone can share a dyno graph with the C38-81 that would be awesome. Has anyone tested the power and performance difference between the C30-94 and the C30-94P?
