Which Fuel Makes More Power? Race Fuel or Ethanol?

Wish I had more E85 stations around. Most of the year it does average 70-74% slightly above sweet zone, even when the summer/winter blend changes. I don’t drive it if salt is on road or below 45 degrees. Speedway in my hood doesn’t carry E.

The differance between pump E85 and E65 for example is virtually nothing when it comes to making power. Like 20-25 hp tops! I average E65 here and made 1500 whp with it so u can make pleanty of hp with pump E at almost any percentage. One Ethanol R will make another 80 hp or so.
