Yes sir it is the 1/8 mile, not sure how that relates as far as time when compared to 9.1. This is the first time I have actually raced at the track so last night was my first lesson. My dyno shows me at 458 WHP, 18 psi on 93 octane. Won 3 of 4 races so maybe ok against the V8's. my loss was when I let off to keep from smacking the wall with my left rear! Now I think it is all due to the short throw shifter"! Thanks for you comments
