Jacobsark Posted October 28, 2019 Report Posted October 28, 2019 My stock bore banshee has 175 compression on both sides I have 21cc domes in my cool head should I be running race fuel Quote
hoppedupandcutdown Posted October 28, 2019 Report Posted October 28, 2019 What's your elevation? Quote
hoppedupandcutdown Posted October 28, 2019 Report Posted October 28, 2019 I'm at 1200ft, with 20cc domes, not near as much compression as you're getting, but have ran 91 forever. I'm gonna guess your gauge could be reading high. Quote
Jacobsark Posted October 28, 2019 Author Report Posted October 28, 2019 I don’t think because before I rebuilt it I had 66mm pistons with stock head and it had 150 which seamed right Quote
hoppedupandcutdown Posted October 28, 2019 Report Posted October 28, 2019 I could be wrong, but a stock head should never net that much compression. Quote
Jacobsark Posted October 28, 2019 Author Report Posted October 28, 2019 that’s was with the bigger bore I’m not to sure Quote
