87bansheepnw Posted October 2, 2014 Report Share Posted October 2, 2014 So I have a banshee. CPI exhaust. Ported blah blah blah and it has 18cc domes running race fuel. Could I just swap em to 21cc and run pump and be done with it if my compression is in range? I'm at around 300 feet above sea level Quote Link to comment Share on other sites More sharing options...
87bansheepnw Posted October 2, 2014 Author Report Share Posted October 2, 2014 Its a banshee that has been in storage for awhile and I'm just now working on again. Can't remember if its 4 mil or not. Say it is why would that make a diference? Gonna check psi tonight Quote Link to comment Share on other sites More sharing options...
