E85 More Horsepower? etc.

Those pesky ecsb 2wds!

Edit: And I am with the majority of the guys who posted in front of me that it really isn't needed N/A.

It will run better NA but like Luke said, its not worth it. You have to upgrade your fuel lines, fuel pump, and injectors.. Which that will get expensive real quick. Personally I like running it just because it burns cleaner, gets rid of the nasty gas smell, is cheaper, and my truck runs a lot better on it.

Fixed.

Don't forget Luke, oh and it burns a lot cooler.. Makes everything cooler under the hood.

... e85 is comparable to 114-115 octane because of it's make up and how it burns and how much is used. Octane has nothing to do with why certain fuels need more or less fuel... it's the stoich of the fuel among other things like if it's oxygenated and so on. regular gas has a stoich of say 14.7... what you get at the pump now-a-days has ethanol in it, up to 10%... The new stoich of pump gas is around 14.2 depending on the seasonal blend you get. C16 has a stoich of around 15.0, depending on the brand. E85 has a stoich of 9.8 ish... To simplify, the lower the stoich the more fuel/volume you need. Say your setup is happy with 12.5 AFR WOT,verified by checking the plugs on "the new" pump gas (stoich of 14.2)... If you change to e85 (stoich of 9.8) you might be looking for 7.8-8.0 AFR WOT on the same setup, again verified by reading the plugs. Every setup is different, so don't take the numbers I threw out as fact...

In conjunction with what you've said here, something a lot of people don't understand about octane ratings is the higher the octane, the harder it is to burn. If you add a straight water injection on your vehicle (sans methanol), your octane rating goes up by about 10 points. Remember water doesn't burn (duh), so this makes sense. Thought I'd add.

I run E85 on my 05 avi and love it. It made the engine run smoother and snappier. It smells alot better and I only lost 1-2 mpg in town and its .70 to .75 cents cheaper a gallon.

One thing I wonder is can any of the tuners make a tune that retains the flex fuel capabilities and adds power with gas or e85 without having to change anything.

I would say yes depending on the vehicle.

You know it's actually more expensive here for E85 than it is for petro? There is one station in the neighborhood (another one north of here about 40 miles). Huge sign out front showing E85 about $.05-.10 more expensive per gallon, depending on the day.
