big--,I'm interested, I'll shoot ya a email, what type of supercharger are you using and what size, mines been running for a few months now, but racing season kicked off and I havent had time to make some changes that I have planned,. mostly they are changes to make it more user friendly, and eliminate the blower surge at idle. Also planning on going to a bigger displacement blower,. been just putting time on the bike to prove the blower drive ect. so far so good. Is this Christian, by any chance? my emails---porche@worldnetla.net --dodo
