BigRed350x Posted March 22, 2010 Report Posted March 22, 2010 40 over stock cylinders and 66mm pistons?? That's some black magic! 66mm pistons would be 80 over. Quote

I wasn't sure about that but I do know for sure that I have 66mm pistons, so does that really means that Im 80 over? I'm a newbie to the "shee". Full drag porting done by F.A.S.T Quote
wacko2000 Posted March 22, 2010 Report Posted March 22, 2010 Id say you are in the low to mid 70's Quote
part-time Posted March 22, 2010 Author Report Posted March 22, 2010 Id say you are in the low to mid 70's Thanks!! Would I feel a big difference by adding out frame drag pipes Quote
cobrabc1993 Posted March 22, 2010 Report Posted March 22, 2010 The 4mill dune/ drag ports i saw dynoed put down 78-80horsepower.... That was to the wheels..... Those were F.A.S.T. port jobs.... Those guys were running cpi and one had shearer pipes..... 35mm carbs...... That was at the littesahara dyno, in waynoka ok..... If you go to rdz's website, he show dyno runs with inframe drag pipes and out of frame drag pipes... Think the out of frames made 2-3hp more than the inframe dragpipes...... Quote

James-26 Posted March 22, 2010 Report Posted March 22, 2010 Little off topic but if a banshee is punched .100 over will that make the pistons 66.5 or 67mm? Quote
