We have been using 110 octane fuel, can E-85 be substituted, if so what changes need to be made? I have already looked in past posts, maybe not far enough, thanks Steve

Have run Aeromotive, holley, magna fuel and quick fuel products and have had no issues. It is a great alternative race fuel. Requires a little more maintenance than gas but not nearly what you would do with methanol. The big advantages are cooler temps, cost and it makes more power.

When I ran race fuel again the last couple years and to complete the season last year the fuel cost was around 1800$ runnign C12. That was 3 drums of fuel. Running E85 I would go through 4 drums a season at a cost of about 165 a drum for a total cost of 660$. For a racer thats a lot of extra tow money.

I have NEVER emptied the fuel system for winter storage and have never had a problem. Well on one car i had a problem where i had used gasket goo on the stock pickup and the fuel dissolved(?) it so the float valves would stick. Guess that would happen on gas too.

The E85 is actually easier to tune because E85 is less sensitive to the absolutely correct A/F ratio, it will give max power over a bigger A/F ratio span than gasoline...and the octane is higher than 101 race gas...

Also makes way better power than gas on those hot summer days. Winter time can be a little tough starting, and warming up. Almost impossible without a lean out valve if it's really cold. Keep your gas carb. Throw it on when it gets cold, and when real winter comes your fuel system is better off with gas sitting in it.

I'v had no problem at 45 deg. temps Also I know keeping the fuel lid tight on the drums will help keep fuel fresh but do uall keep drums off the ground(on blocks)? Not trying to jack this thread, but sense were on the subject.....Thax.

I kept my drums on the shop floor(heated concrete) during the winter months.. sealed drums... I never had any issues with the drums or fuel.. if it was on a dirt floor in a pole barn I would have the drums on wood (some 2X4s) just so the moisture didnt bother the drums
