hey guys,

just wondering i just starting running race fuel through my motor c12 108 octane with bel ray syntheic oil...ive been using pump gas in the past and the previous owner used it too with a 32:1 mix...today i ran race fuel and it ran real strong and never bogged in the upper gear but it seemed to be running a little rich..so i wondering if i should use 40:1 since im using race fuel now..btw my compression is 225psi

If it's running rich, just rejet it.

I agree, it's a jetting issue. I run 110 leaded 32:1 at 222psi with no problems.
