You are completely right, when I rebuilt the engine I tested it, and it was right at 175 on both sides. And yes, I am running race gas. A buddy of mine races his dragster, so he's always got some that I buy from him plus a little extra to boot for him. It looks like a shop somewhat local to me sells race fuel. Turbo blue: 100 unleaded, 110, 113 advantage, and 116 extreme, as well as VP Racing fuels, which includes C9, C12, C16, Q16, Motorsports 100, Late model plus, VP113, U4.4, and VPR. Any recommendations on which would be the way to go? Was thinking the Turbo blue 100, or 110.
