e85

[JayRolla]

A mod moved this to tuning tech when the guy that started the thread is a newbie. Hopefully a mod see's this and moves it back to the newbie section so he can post in his own thread.

Can anyone check out what it would take for me to run E85 please??? I'm really tired so hopfully I wont get yelled at for this.

Im gonna be honest....If your profile is up to date......Dont switch to E-85......

well it depends on how much power you want to make, i have made 445hp on 760's, and i have made
520hp on 880's on my frinds car, and on my buddies teg 575hp on 1000's. if your not planing on making more than 450hp then get 760's-880's and your neo will work fine. hey i have even made 300+hp on a 14b at 17-20psi on e85.

I`m running ~17PSI (have some boost problems, maybe BOV is the limit) with Evo3 turbo and 25-25° timing, Lambda 0,7-0,8 whole range. (4knock maximum)
inj. are 850 FICs hopefully still have some air to turn up the boost

and please do not talk about 11,1afr! thats wrong, very wrong... its an afr for gasoline converted to E85.. no real AFR! if someone missunderstand that: blown engine!

The E-70 and E-85 is the reason i went with the EMS because after i tuned in the fuel that i had in the tank at the time. I setup +-10% fuel trim vs wide band and tuned everything in lambda.

The cost difference of the ecu was not much compared to killing a motor.

 

[Raptoreborn]

I've read a few benefits of using E85 and thinking of converting to use it. Will E85 be effiecient/sufficient form of fuel, say in the next 15-25yrs?

 

[JayRolla]

If its not then I guess we will all have to go back to pump gas. But for now its race gas at a cheap price.

 

[JrCRXHF]

The only down side i have found from switching back is that it is harder to get the big injectors to idle besides that i see no difference going back to pump gas.

besides the loss of performance.

Exactly thats why I mention a wbo2 is essential when running e85. Its technically never really 85% even during the best time of the year.

I tested it to over 90% a couple summers ago at one station about 20 miles from me.

I think the AFR is less critical than with gas, unless you have high compression and are really pushing the limits.

If I run any richer than about 8:1 (12:1 gas) my car runs crappy. My 1g seems to like it richer, although I don't know exact AFR since I have no wideband in that car.

i run about 11.5 a/fs on my car, i have heard of people running leaner that
12.5 on e85.....abel up at abel racing has tuned my freinds car at 13.0 a/f's
on a 16g set up...

 

[JrCRXHF]

why don't you guys just tune in lambda then it will make no difference if it is gas or ethanol.

So E-85 drops you're gas millage down from about 25ish to what, 20ish at the most for highway cruising? I have several stations here with it, and with premium being expensive, this may be a viable option at something like 40 cents a gallon cheaper.
