If it's in a buggy, flip a coin, if it's in a truggy, 30%.

I had 1 in a truggy & NO bottom-end in that engine!

go with 30% fuel... use pipe rb2045 with a 198mm header pipe.... this will give the most run time and the most bottom end for this motor. also use 1.0/1.1 springs in the clutch.. this will be determined my the track surface you run on.... jeremy

I would run 30% for sure i switched last year from 20% Bryon's to ColdFusion 30% and man the 30% ColdFusion is much better i get a lot smoother Idle and the motor temp stays around 220. In a 30min race it might get up to 225-230 and motor makes ton of power and runs GREAT.

Lets make it easy! If your a serious racer use 30%. Although I have seen a hand full of guys use 20% for engine life but then run the motor hotter. Without making your head hurt use 30% Sidewider, Byrons or Nitrotane

30% Platinum. But definately 2045 pipe with a 198 header. I have a buddy that had one of these in his buggy, nice engine for a small to medium track in a buggy
