Spec B Posted June 12, 2012 Share Posted June 12, 2012 I have been running exclusively E85 for over 1.5 years without any problems on a very solid tune. I drive on the weekends only and have probably racked up 6,000 miles over the last 18 months. Overall the car is running as strong as it did when I first switched off of pump. Considering the amount of time I have been on E85 exclusively, should I consider doing any preventative maintenance to the fuel system? Like a fuel additive or revert back to pump for a while?

LGT For ME Posted June 13, 2012 Share Posted June 13, 2012 I'm on E85 for about 2.5yrs so far and about $20k miles. All trouble free. If you ask Legend he's been on it for I believe 4+ yrs and running it year round with no problems. Link to comment Share on other sites More sharing options...
PutnamCO Posted June 13, 2012 Share Posted June 13, 2012 I've been running E85 exclusively for almost two years, 40k miles. No problems at all, and still loving it. Link to comment Share on other sites More sharing options...
dr_sharp Posted June 13, 2012 Share Posted June 13, 2012 Do you guys drive hard? I mean, how often you take to the redline? Because Racars. lol Link to comment Share on other sites More sharing options...
PutnamCO Posted June 13, 2012 Share Posted June 13, 2012 I autocross and do open lapping days at a road course several times per year. I would guess that 1/3 of my shifts occur above 4k, and I shift at 6k at least 10x per day. (I try not to shift above 6k because power drops off after that anyway).

PutnamCO Posted June 13, 2012 Share Posted June 13, 2012 Yeah, I don't see the point of having lots of power without enjoying it. I make sure I do everyday. Glad to hear you do too. Link to comment Share on other sites More sharing options...

Spec B Posted June 13, 2012 Author Share Posted June 13, 2012 You are totally right...I tend to baby it most of the time and then open it up for a few runs. It's like I am expecting something to break or something. Link to comment Share on other sites More sharing options...

Legend Posted June 13, 2012 Share Posted June 13, 2012 @ Spec B: I was going to suggest you post this question directly to the experts (my "buddy" up the street, hotrod). I see that you did. Good going! In for a response. @ LGT for me: Yep 4+ years on E85. (Proof here!) I have never gone back to 91 and I've never tuned for it either once I made the switch. No issues, other than cold start issues, which are pretty manageable. My '05 LGT My '07 Supercharged Shelby Link to comment Share on other sites More sharing options...
m sprank Posted June 16, 2012 Share Posted June 16, 2012 I have multiple cars running e-85 (including my own SpecB). No issues. Link to comment Share on other sites More sharing options...
Spec B Posted June 17, 2012 Author Share Posted June 17, 2012 Cool...so not long term issues directly related to E85. Sweet. Link to comment Share on other sites More sharing options...
Hepy117 Posted June 18, 2012 Share Posted June 18, 2012 @ Legend If you don't mind me asking what kind of power did you put down with your 52 on e85? I'm putting one on my car and going to tune for pump gas. Then when I get bored with that power I am going to get tuned for e85 but would be nice to see what I can expect (ballpark, I know all dyne's read differently and whatnot).

m sprank Posted June 19, 2012 Share Posted June 19, 2012 He is also at elevation. Anticipate 80whp gain with e-85 and supporting mods. Link to comment Share on other sites More sharing options...
dr_sharp Posted June 19, 2012 Share Posted June 19, 2012 Anticipate 80whp gain with e-85 and supporting mods. I got 60whp gain from stage 2 to vf48+e85. I guess my tuner sucks lol Link to comment Share on other sites More sharing options...
13larry Posted June 19, 2012 Share Posted June 19, 2012 What year is you ride? I do not believe you should need to do anything, many cars are now flex fuel. Link to comment Share on other sites More sharing options...
m sprank Posted June 19, 2012 Share Posted June 19, 2012 You need to upgrade the fueling. e-85 uses about 30% more fuel. You need larger injectors and a pump to get the real benefits of e-85. Wasting your time on stock fueling. VF-48 is what held you back sir sharp. OEM turbos fall on their face at 4800-5000rpm no matter what. My 68HTA held 25psi from 3400 all the way to redline on e-85. Our average gain at sea level is 80whp. We have seen higher. But rarely less. My own SpecB gained 85whp on the e-85 tune over the 91 pump gas tune. If starting with 93/94 pump gas, gains will be slightly less as you started with more. Link to comment Share on other sites More sharing options...

Hepy117 Posted June 19, 2012 Share Posted June 19, 2012 That's a pretty respectable gain. So pretty much I will easily be able to get over 300whp. Works for me. This is my DD so I am not looking at going crazy Link to comment Share on other sites More sharing options...
dr_sharp Posted June 19, 2012 Share Posted June 19, 2012 Yes, if you're asking specifically about a VF48/52 with fueling upgrades on E85 at near sea level... 300whp is the least you should expect. lol Link to comment Share on other sites More sharing options...

Then when I get bored with that power I am going to get tuned for e85 but would be nice to see what I can expect (ballpark, I know all dyne's read differently and whatnot). On my dyno the difference b/w stage 2 91oct and stage 2 E85, after tune, is a difference of 10-11% whp and 17-18% wtq. Enough for me to improve my e.t. at the dragstrip by 0.6s and 4mph trap.
