rugrat30263 Posted May 14, 2006 Report Posted May 14, 2006 I finally got the Banshee put back together and checked the compression. It only had 120 pounds of compression on both cylinders. It now has 69.5mm pistons, and a Wiseco 4mm stroker. Do these numbers sound right? other than the pistons, and crank everything is stock in the engine. Quote
hittintrees srh Posted May 14, 2006 Report Posted May 14, 2006 Is it ported-if not your compression does sound a little low. what size domes are you using? Quote
cdwood37 Posted May 15, 2006 Report Posted May 15, 2006 yeah it sounds low, but what is your elevation that has a lot to do with it, mine stock out of the box was about 110 pounds because i am at almost 6000 feet. Quote
RIPPEN Posted May 15, 2006 Report Posted May 15, 2006 Dune/play port at almost 5,000ft with 17cc domes I was around 177 in each side.. RIPPEN Quote
dajogejr Posted May 15, 2006 Report Posted May 15, 2006 Two things. Did you get a spacer plate or are you running cut domes on the head? What is your elevation? If you got the head cut, did you get the porting matched for the longer stroke? Quote
rugrat30263 Posted May 15, 2006 Author Report Posted May 15, 2006 I have the stock head, Elevation is around 1000 feet above sea level. No domes and I dont know if it was ported, the edges of the ports have been smoothed and appear to have been rounded. Forgot to mention, I have Trinity stage 4 intakes, 35mm carbs and k & N Filters with outerwares. The stroker came with the spacer plate and longer studs. Quote
