I have not used it personally,but another racer I know used some and said it allowed him to run a couple more degrees timing over the Torco 110 he had been using and it gained him a tenth.
This was in a 10.20-ish small block Chevy powered car.He was trying to get into the nine's with it but did not quite get there.I told him jetting with the new fuel would possibly get him there,but some guys "know everything"!
