E85 does not vaperize till 165 degrees, so you need to be that before you stage. There is alot more to it than just bolting on a E85 converted carb. most agree you don't need to run over 7 pounds of fuel pressure. I buy E85 locally, just be sure and check it with a tester so you know what you are getting. My local station changes content from E85 summer to E75 winter blend. I will buy enough to fill my 55 gallon drum in the summer when they have the true E85.

I live in northern MN and we only have true E85 two months of the year and it ratchets down to E70 through the winter. A friend dynoed his motor and set the carb up in midwinter with winter blend E85 and by the time he got the motor in the car it was early summer and he was way off on his tune and jetting using the E85 sold during the warm weather months. His 540" bbc picked up 40 ft lbs and 25 hp over pump gas. It is a 10 to 1 pump gas motor in a street car. It works fine except the gas tank is alittle small because of the higher fuel consumption.
