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.

Well with 105 Octane and prices near that of premium fuel even after accounting for the difference in fuel burned the reasons are obvious.

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.

if the fuel were more available here I'd do it on the gto in a heartbeat.

Philip

though I'd have to do a MAJOR fuel system upgrade to run that much fuel.

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.

Philip

13,2?
christ I can do better than that at over 6,000 feet in altitude.

I'd run it if cost effective...but its not. If they'd get real on price, so it were even with gasoline, I'd be all over it.

less fuel mileage with e85 It would be worth the cost at about 20% less

The first 1320ft falling off the 6000ft cliff? :gay: It's not to bad for a v6 considering the weight of THAT car.

Isn't one of the members here running E85 making 470ish rwhp?

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.)

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.

oh, its been hard to find in OKC, and only available at a couple race car shops. How much power can I make on 550cc injectors with a stock fuel pump on e85?

bripab007

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

Yes, compared to other forms of fuel that allow you to run much more timing advance and boost, it is cheap.

Markp

Well let's compare that with VP C10, I just checked froogle and the cheapest I could find C10 was about $8.66 a gallon. Of course, I will use 30% less to make the same power as E85. I would consider the power potential of these two fuels to be VERY close. So worse case E85@2.71 per gallon would work out to 3.51 per 1.3 gallons - the same amount of fuel that you would need to make the same power as 1 gallon of VP C10. Hmmm $3.51 vs $8.66, I don't need help to do that math!!! Now lets just say that I am full of crap and you can get VP C10 for $5.00 a gallon... it doesn't matter... it's still $1.50 a gallon more than E85 even after adjusting for the extra fuel burned.

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

Mark

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.

yeah but with e85 you will only be able to make 200 or so whp on the 550's that is bullshit. we only have so much room for a fuel tank, i hope e85 blows up in there face.

Markp

That's the funniest **** I have read yet. Plus my trunk has plenty of room for the 12 gallon fuel cell and the 12 gallon stock tank. I think 24 gallons of fuel is gonna be enough to get me around the block.
