So I am thinking of getting tuned to E85 and was just wondering who is all running this and what are their setups? Also what are the advantages and disadvantages that youve seen?
Thanks
Ok.. So to clear it up Yes.. E85 is rated at 105 octane. It does run cooler through the engine. and you are able to advance the timing a great amount. We use turbo's to force air into the cumbustion chamber well E85 fuel actually carries alot of oxygen within the fuel so with the addition of boost you are getting more air, so in return you need more fuel, Hence the larger injectors and fuel pump. I hope this helps clear it up for you.
E85 changed from state to state and what time of year it is, I'm from Iowa and our octane on it is 107 with no less than 75% ethanol but no more than 85%, not all the ethanol comes from Corn ours doesn cause that is all our state grows, and we have 2000 acres of corn on our farm so its good for us lol, but i did find out that the state of Colorado will buy back old Coors Beer and they turn that into fuel, just something to throw out there lol
I just wanted to throw out one more thumbs up for E85. I have about 15k miles on my 2002 WRX daily driver running E-85 with only one complaint. Cobb hasn't unlocked the cranking enrichment map for the 2002 so it won't start in the in the winter (below about 45F) on E-85.
On a bone stock WRX (except for pink injectors and walbro) I got 226WHP on a mustang dyno with E-85 versus 205WHP with a pump gas tune.
