watkins Posted October 20, 2005 Report Posted October 20, 2005 Loading the truck up for a trip out to Glamis and wondering if I should pickup some race gas just to be safe. I am running 156 psi compression with +4 timing. Should I pick some C-12 up and run like a 20/80 mix of C-12 and 91? Quote
Proquad101 Posted October 20, 2005 Report Posted October 20, 2005 I dont think you will need it. Quote
Ducman Posted October 20, 2005 Report Posted October 20, 2005 With 21cc domes at 156 you should be fine on 91octane pump fuel. Quote

BansheeBrian Posted October 22, 2005 Report Posted October 22, 2005 The higher elevation= lower compression + vise versa. Quote
