First off, I know this topic should probably be in the racing section, but that section isn’t near as active.
I have a Honda h22 engine (soiled valvetrain, very prone to shear at the rockers. Rebuilt by me with stock clearances, with a very mild cam and some mild valvesprings: Makes 213 WHP.
This engine is strictly for dirt circle track racing where it sees hot summers (~100F). Sees short runs (15-20 lap races mostly, 3/8 mile), and revs to 8500-9000rpm twice a lap. Was running 10w-30 Amsoil Dominator for the winter races but wondering if I should bump up to 15w-50? Any input is appreciated
