E85

[billy leber]

Kinda but not really Tom ..lol I did not change the cam when i changed to E-85,however when I broke a rod I changed the cam during the rebuild. The motor went from the Vette to the Dragster at this time so I dont know what the change did. Current cam is .866 , .808 ....283,304@.050 .

I forgot about the temperatures, mine too runs about 10 deg cooler, a little harder to get it up to 160 compaired to gas.
I havent done much in the way of tuning and testing, but reading you guys, I will be playing with jets soon.

I found starting my burnout at 160 works most consistently . I was starting at 140 and forgot to turn fan on so I continued to start at 160 for the rest of the race and liked it better.

Sounds very close to my cam ,altho I run a very wide lobe seperation.
I was thinking about E85 earlier this year,but I had 2 drums of C14 to use up so it kind of went on the back burner.

My lobe separation is 114 . I love paying $3.50 a gallon and only using slightly more fuel . 15-20% more.

Can't find any E85 in 55's in S.E. PA or South Jersey. Any help? Thanks

Both VP and Sunoco offer E85 race fuels.
Check with Jeff Stricker at Roadrunner Race Fuels.
He's located right near Maple Grove.

Been running E85 for over a year now and had some experience with it. Had some carb problems until I got hooked up with Mark Sullens, he is the best, you can go to his website and get some valuable information on what temp to stage and tuning. 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.

The experience of those who know E85 say that going from E70 to E85 blend is worth about 2 jets sizes larger, (needs to be a little richer), but it should not make your tune-up "way off" if it was close to begin with. Some setup with E85 and never change jets, as the cooler weather itself cancels out some of the effect. But this is why a tester is very important so you have a starting point to know if it could be the fuel or some other variable if the car begins to not run properly.
