E85? What do you guys think about it?
What are the benefits and disadvantages of it?
Is anyone here running it in a daily driver? If so what is your setup? (injector size, boost level, timing & AFR in boost)
I know it's cheaper per gallon than gas but does it offset the fact that you have to burn more? Is it cheaper, more expensive or about hte same in the long run?

I've been running it for about a year now in my Cadillac CTS-V. Disadvantages for me is poor gas mileage but being that it's my fun car and not my daily, it doesn't bother me too much. E85 is fairly abundant near me which helps. Advantages of it are that I pass emissions (sniffer) even without cats on the car. I assume it's still running clean enough. It made me 60RWHP off E85 alone (mods are in my sig). I'm only running 5lbs of boost on my maggie until the OD crank pulley goes on, then probably 7-8lbs.
hmm.
when it ran for the couple days it did, (broke a ringland, i think, pistons look amazing from the top)
lets see, i hit 14psi by accident, some where around 13.5 afr and never the slightest hint of detonation....
and this happened way more then once, the afr spikes that is, i did a pull @ 13 on purpose, at that point i didnt really care if it got cooked, 60lb injectors, 9sectruck DIY twin intanks, lol. and id say timing was up around 23 or so... IIRC, i have to look at tune to verify, but im positive as it sits, im running 23 or 24* max timing at WOT.
on the 14lb pulls i was using 80# injectors, and is currently how it sits, but was running out of injector fast on the 60s around 8psi

I run it in my daily driver S10. Its a 2003 with a stock 5.3l and a 224 cam with a 112 maggy. On pump fuel It got 17mpg and made 400rwhp went 12.6@113 @3900lbs. Switched to E85 and put some timing to it and make over 470whp and went 11.8@120. I drive it everyday and achieve about 12-13mpg. My actual fuel cost is almost exactly the same from week to week.
Oh the important part....255 in tank, vette regulator (semi-returnless), 60's IDC is at 82-83%.

E85 rocks, other than the fact that is smells terrible.
You need to keep in mind that E85 has seasonal blend changes that would affect it's stoich, here is some info:
Key (Ethanol/Hydrocarbons): Class 1 (85/15) is the summer blend; Class 2 (80/20) is the transition blend utilized in the spring and fall; and Class 3 (75/25) is the winter blend.

Good info 'Trust'! I know several guys running it around here, making big power. Stock bottom end T/A w/ a 70mm Turbo, E85, twin in tank 255s, not sure on injectors, making 655rwhp corrected, running 10.29s... Not sure on gas mileage. We have a supra here making 848rwhp on e85 as well.

I would do it personally, but there aren't enough stations here for me to feel comfortable doing it for a street car, that and my car shouldn't make much more than 12-13psi to make the power I want it to.
You going to Lubbock next month?
Awesome! Lots of the guys around here are running it, local Evo should be right at 650whp with it, one of the TT Cobra's was on it for his low boost tune and was right at 770rwhp (not enough injector to do the 1000rwhp tune). Everyone is converting!

As for Lubbock, I really want to, but I just can't afford it right now, money has been super tight lately. I will be at TX2K11 though, looks like TSC may be sponsoring the event this year. I don't think my car will be making the trip though, the new setup won't be done by then (money pwns my face, being a 22 yr old college student and all).
Been running on E85 for over 2.5 years and love the stuff.
I've managed to tweak my tune to run a little lean during cruise conditions and get 22 mpg...Several trips to GA helped me work the tune.

Yep, 55 cents cheaper on average vs 93 octane. I personally don't run it to gain a lot more hp, but more of a safety margin b/c it gets pretty hot here on S. Florida. My Supra and EVO buddies have gains of 70hp peak going with E85. Remember it's in the tune and how far you want to take it. I have a bud whose got a 5.3 bone stock over 100k miles and run 14psi and over 23* timing putting over 700rwhp all day with his set up. But then again it appears the 5.3 and 4.8s have thicker deck allowing them higher safety margin to blowing up their motors.
new to this turbo stuff and loving e85. It goes from 1.93-1.99 at the station here in Kansas City that I buy it from. I just keep 3 5 gallon gas cans with me filled up when I go street racing so i never run out
It's a good 50 cents cheaper per gallon here also. The other thing to note is that it takes 30-35 more fuel at WOT but at normal cruise, it's only like 10-15% more required so, yes, the cheaper cost offsets the additional consumption. Not to mention that you are comparing it to 93 octane at under $3 per gallon. But for what we are doing with it, you should be comparing the price to C16 which is about $80 for a 5 gallon drum around here. That's $16/gallon.
