Set me straight on pump gas
not here it isn't. there are only a select few places that sell it. and it is the same price as regular gas. 93 is pump gas.
I have a local friend with a well built 03 cobra, and he spent a couple thousand dollars swapping his fuel system over to e85. bigger injectors, pump, new lines, etc etc... car made 10 more whp. and ontop of that, the car sat for about a month in the shop. the next time he cranked it up, it was running terrible. turns out in that time the e85 had corroded and destroyed his new injectors and some fittings started leaking from the fuel eating the rubber in the lines.
so you guys can have fun with all that, I will stay far away from the stuff. I have an air to water, so I should be able to bring my AIT's down enough to run comparable timing an power numbers

i was running my forged 402 with aps twins for a few years on pump gas...made 633rwhp. unfortunetly the turbos gave up on me or it would still be driving around. i switched to a F1A and hope to make a little more than that power wise but still stay on pump. i will have meth hooked up as a precaution though. a good tune goes a long way like stated before.
I can think of 4 customers off the top of my head in less than 5 seconds that we have making 800rwhp and up on pump gas.
- 408/F1R Air to Air I/C=850rwhp on pump gas no meth
- 347/Novi 2500 Air to Air I/C=820rwhp on pump gas no meth
- 402/F1R Air to Air I/C=790rwhp on pump gas no meth
- Stock bottom end LS3/YSi Air to Air I/C=812rwhp on pump gas with dual 7gph meth nozzles. The methanol on this one was more so for added safety with the SBE.
None of these cars have over 18* timing advance up top and most are in the 12-14* range at peak torque IIRC. All of them are running 8 heat range plugs. The three built motors are in the 9.2:1-10.0:1 CR range with the SBE LS3 being the highest CR of all 4 that I mentioned with 10.7:1 which they come with stock.

I did use it for a while on mine, but really didnt see the need going colder than a 7, so I'm back on a 7 now.
But there were no issues running the 8.

Yes. 6.0's in the 1/8th in a heavy car, stock suspension, full interior, sound system, sub woofers, street tires, and just learning to tune. I thought that was pretty solid. 118mph.
Obviously you don't know too much about E85. I agree if you have a great tuner and want to pay someone to tune your car then run 93 and meth or 93 and no meth. However, I have spent no money on having my car tuned and have learned how to tune on my own. If I wan't running E85 from the pump at $2.62 a gallon (105 octane) I would blow my **** up every time I run it down the road. If E85 is available it is a no brainer to use it. You are paying regular gas prices and getting race fuel for the most part. Different opinions I guess but you can't say E85 isn't pump gas when it is sold at the pump like 91 and 93 in a whole lot of places.

btw those are really good numbers for a street trim car. I am not arguing your success. I'm just saying that the same results can be had with regular pump gas, with alot less headache. I am shooting for 5.90's with my 5.3 at 3250 raceweight with air to water on pump at around 15-16 psi

Oh and his tuner obviously wasn't that great either. First time I switched to E85, I tossed a few more degrees of timing, a few extra PSI, and better fuel trims at it, and picked up a good 20% increase over pump gas that was at its peak on my setup because it was seeing detonation. No other changes to the setup.
no, he bought stuff that was "compatible", as were the $700 injectors that corroded up and were ruined by it in a months time. I won't mention the shops name, but it is a VERY reputable shop that did his tuning, and I believe they may even be a sponsor here.
my argument with it is:
people say you need about 20% more fuel system capability with e85 to run your same numbers because it takes more of the fuel to make the same power. why not upgrade your fuel system to handle that much more fuel and run pump gas? then how much power will you be making? I understand you can get more aggressive with timing, and that's cool and all, but what if you are putting more fuel to it and can just turn the boost up some to compensate? even if you have to pull more timing, you will still make more power than you were before

JUST switching to e85 won't pick up that much, the more timing and boost that it lets you get away with is what makes it worth it
Plus it's a whole lot safer, and if your running 1000rwhp are you really worried about less mpg's??
