CLASS RACER FORUM - View Single Post - which is faster- VP C-11 or C12

What makes the most HP depends entirely upon the combination. Also, to get the most out of a particular fuel, you have to do a ton of carburetor and timing tuning. There is no easy cut and dried answer. Every combination is different, and some carburetors, if you run a carburetor, do not tune easily, and may be near impossible to get tuned to a particular fuel.

Personally, I hate C11, it always left out fuel systems filthy. I got better performance from C12, but passing fuel check was hit or miss. The price of VP fuel is absurd, considering you may get a batch that fails fuel check 2-3 times more often than it passes.
