CLASS RACER FORUM - View Single Post - Any performance difference in Sunoco Purple?

You need to be a little more specific. Sunoco is the official fuel of NHRA and IHRA, but any performance changes or jetting adjustments may depend on which brand and octane one used before as well as the engine combo. All of the same fuels are still legal as before in the sportsman classes. One doesn't have to change brands, but Sunoco will probably be easier to get.

I've used Sunoco Purple.....about forever, in brackets and IHRA, and have been happy with the performance and consistency. I'll stick with it when I get into NHRA as well.
