Fastest I ran was a 12.2 @ 112 - car running 1bar ish dropping off - zorst and bleed valve. Rear seats and crap out and small wheels really seemed to work. Ran lots of 12.5s but 12.2 was the utter best on a dodgy clutch which seemed to launch just utter perfect

Supposidly the car had a fueling mod also done so it wasnt as rich as a standard 1 bar job - never melted so never complained
Good little machine till i did some forestry work in it
