Winter changes on the AMX. Are you going to make any changes on your race car?

Got a tester and I always test at the pump before I fill my jugs. So far the fuel has tested 83-85% every time. In Washington State, it is a state law that the fuel is a certain percentage of the rating which really helps ensure we are getting good fuel. Problem is, that drives the price up to about what Premium (92 octane) sells for.

As for carb, I haven't decided yet but the 2 I got quotes on are from Thumper and Pro Systems.
I buy my E85 from Forged Fuels. 4 bucks a gallon. I run a Horsepower Innovations carb. Do lots of research. When I bought mine Mark Sullens E85 and Horsepower Innovations seem to be up top for custom carbs. There's a handful of decent builders now. I haven't heard much good about Pro Systems for E85 but I also have zero experience myself with them.
