Lightbulb Lower compression...

Anyone try the lower compression rotors from hayesrotary? I think they lower compression to like 9.5:1. Just wondering because it seems like theyd be nice for high boost applications.

8.5:1 are stock series IV TII rotors. Most big power guys use 9:1 or even higher 9.7:1 (w/ alcohol inj, race gas). 8.5:1 is too low in my opinion.

How much boost are you planning to run?&nbsp Lower CR's are important only if you're planning to run high boost over 15psi?
