Bob, I probably missed the discusions on turbo compression ratios,...but what is the theory behind reducing 'squish' in a blown motor ? Is it because you don't really need more turbulance in the chamber ? I've had some problems with detonation in the Harley XL-1200 motor with 10.3 (cc'd) to one and 10 psi boost. Solved it with water injection and timing retard, but my original thinking was to maximize lower rpm efficiency and torque, one of the twin's trademarks. BTW I did thermal coat the pistons,..which I'm SURE has enabled it to survive all the experiments and tuning mistakes. I'm anxious to take it apart to look,...and fiqure I'll gather as much info as possible for the first overhaul. thanks, Jeff Churchill J.C.
