Sweet, another e85 user. What's your mph in huge 1/8? I just got mine to the track. Ire doing 7.12 in the 1/8 and ran 11.29 @116. My afr was at .74-.75 (10.8-11.0)on the big end which is rich Ive got it down to .8-.82.(closer to 12.0-12.3) Hoping to get a few more mph and possibly into the 10s with leaning It out.
