It was at the tail end of the dyno session and we didn't compare any farther than switching from one fuel to the other, so I don't have an answer to that one.

Ron, which engine do you run?

Renegade R11 is a good option also.

Some good info to work with. Ran the new 350 2 barrel combo on pump gas last weekend. 1/8 mile hits only. Divisionals this weekend . Will have C11 in It. Interested in comparing 1/8 performance of 3.50$ gas to 15.00$ race gas. Probably faster on pump gas.

STK. 6380.

Call Jason @ Insinger fuels, he will give you the lowdown on the Surge and any other Sunoco fuels, I have been doing some testing with the Surge for them and he has my info and others on the results.

Be careful , Flush your fuel system out with race gas , or you could possibly get bounced at fuel check .

An you mix race gas...so long as it done now have ethanol.
Not all tracks carry the same fuel
