E85 tuning, anyone here running it?
The big thing right now where I live is converting your car to E85(85% ethanol fuel). The procedure is different depending on the vehicle, but for most cars it means larger injectors, higher powered fuel pump, sometimes different fuel lines and injector seals, and of course a tune on the stuff. Just curious if this is big anywhere else around the country. I've seen everything from a 400hp E85 turboed 4 dr civic, to a E85 tuned turboed v6 automatic camaro. People are getting some crazy power with this and quite a few shops are doing it around here.

I am getting ready to make the transition myself, I just got my 1600 cc/min low impedance injectors and I will be ordering the fuel pump very soon. I was running about 300 RWHP on 93 octane pump fuel and expect to punch out around 450 RWHP on 105 Octane E85.

Yea...my buddies v6 turboed camaro ran a 13.24 at 110mph today on the stuff. It seems to be growing in popularity around here...but I know that there are only a few stations that sell it and other places it is pretty much unheard of.
So I called Kroger in Dallas figuring that it might be astronomical in your neck of the woods. They told me $2.70 a gallon. Bitch Please! That's cheap for 105 octane race gas.

How can you say it's not cost effective. It's ******* $2.40 cents a gallon in San Antonio, TX. The cheapest premium is going for is $2.90 (good luck finding many stations at that price.)

Yes, compared to other forms of fuel that allow you to run much more timing advance and boost, it is cheap.
So it costs ~21% less, but it also has only ~72% the energy content of gasoline, so each gallon of ethanol will net fewer miles than a gallon of gasoline. But you knew that

I realize that this is what you already know. I just want to drive the point home for the E85 haters out there.

PS - 550 cc/min injectors would max out around 270 RWHP even with 60 PSI of base fuel pressure. This is why I switched to 1600 cc/min injectors, that's a little overkill but my 880's will max out at about 400 RWHP.

It would be worth the cost at about 20% less
