I tried the 110 octane Vp oxigenated. and it made no changes. then the man tells me it was because I needed the 116 Octane because of my compression ratio. I'd like to know if anyone has tried it before I go spend $65.00 on fuel that I don't need.
Thanks Andy
Cant say about smaller motors, but it did pick up almost 40hp on my 632. And yes, it is nasty smelling and it needs to be run out of the carb and fuel tank drained after every race. And you will need to go up 3, 4 maybe even 5 jet sizes.
