Is Anyone Running E85?
I ask out of curiosity, and don't plan to convert. I have seen a few posts where it was discussed, and I the subject interesting, and very educational.
I am also wondering if I were to have trouble passing a tail pipe emissions test, would adding some E85 to the tank before the next test help? Say, 10-20% E85, and the rest prem dino? What problems with this cause for my motor? Would I run super lean, and risk detonation? Again, I ask out of curiosity, and have no plans to actually add E85 to my car.

I did perform a search, but found a lot of threads where people are bickering about the merits. In fact, most of the threads were painful to read, and I never really got a feel if anyone is actually running E85. I was also trying to run up my post count since you can't do much around here until you hit 10 posts.

i make 340 whp now on 93 octane at 22psi
i can make 440 whp on E85 at around 27, 28 psi without changing a thing other than adding 1600cc injectors/advancing a whole bunch of timing and retarding the intake cam a whole bunch
yeah, i'd say it's definitely the easiest way to make more power.
All i need is for the state of Florida to hurry up and build those U-Gas stations up and down the FL Turnpike, currently, the nearest E85 station is 25-30 minutes away.

30% more fuel? I can see some of the track guys running out of fuel pretty quickly with our tiny stock fuel tanks. More power is good, but on a DD I can see where 30% less fuel economy across the board would suck.

You know... I hadn't really thought about the on track fuel consumption thing. That could be a little bit of a road block. I'm only planning on running track days, TT, and Autocross though, so I might be able to get away with it. I was planning on running E85 just for kicks and giggles, since I'm only planning on making ~250whp. Might just have to go for 94 octane and skip my epic E85 fuel system build.

11-13 PSI, IC only... no ignition management at all... on a 99. 325cc injectors with BEGi FMU maxxed out with 02 clamp. Jerry rigged as hell but it's my beater and been reliable as **** for the past 1+ year of all weather driving.
As for the fuel economy... I notice that a full tank does not get me as far as it used to; but on the flip side is that the e85 cost less and lets me run more boost. Win-win situation.
Ohh... car runs great without boost too.. the e85 made a difference even after the turbo came off. Left all the other parts on (FMU and whatnot) and e85 still makes the car feel better. Who knows........
Now on my 02 SE, not planning on E85 since Adaptronic let me use 600cc injectors and adjust timing. If I have time and some help, I will research how to do E85 on my 02.

Don't worry, hyper will be along shortly to propose that the E85 fuel be super-cooled prior to injection by passing it through the heater core backwards.

Fortunately the OP set him straight, albeit in a polite, m.n acceptable manner.
