Hey Greg, I switched to E-85 (out of the pump)in the dragster at the end of last year. I'm at 14-.3 comp an it's working well. First of the year I ran a best of 7.37 @ 180. It's a pretty big camshaft that brings down some cylinder pressure. $2.99 per gallon.
Great info Don! Glad it's working for you. For lower compression motors ( say less than about 12.5/1)
I posted in another forum about mixing to a lower ethanol content for two reasons. By going lower , like to 50 or 60 pct ethanol you can always adjust the pump e85 down to what percent you want. The other reason is at some reduced percent (e50?) You should be able to run the mix in a box stock race holley. A e50 mix should be able to go richer to the 20 percent higher fuel flow required by the E50 versus reg gas. So if the fuel system can handle the extra flow and the carb a guy has can flow the right mixture, for some guys it could be a real win win.
