What does your fuel burning cool have to do with your intake temps? Aside from the small amount of heat transfer that will occur from your head to your intake during operation and any reversion... Intake temps are dependent on the efficiency of your turbo, IC, and the temp of the intake into the turbo.

Anyways though, E85 is higher octane and does have good potential. But, like you say, you need more of it; about 1.5times as much IIRC.

Now, E85 does burn cooler, but your intake temps aren't a direct result of this unless you are maybe sucking in exhaust gasses?? Your combustion and exhaust temps should be lower, which allows wilder tuning:icon_thumleft:

I should get some bigger injectors and run the Yota on E85...:icon_scratch:
It works on the same principal as Methanol but just not as effective. Ethanol vaporizes with the incoming air to reduce intake temps. The reason need to run 50% more fuel is to have some ethanol injected into the combustion chamber after the vaporization has occured. Thats why on a car running methanol you don't need an intercooler or sometimes even a radiator. The cooler the air coming in, the more power you can make.

Sorry, but you're wrong. If you want to compare octane ratings, e85 is rated at 105 octane. I'm paying $2.49 a gallon right now for e85. I beleive c16 is around $9-10 a gallon. You do need to run more ethanol to equal the same amount of gas. Anywhere from 20-50% more fuel. I get about 22mpg on e85. The best part of e85 is that it burns cool. Last week on an 80 degree day my intake temp was 94 degrees. After some spirited driving the intake manifold is room temperature to the touch.

wouldn't you pull more power with regular 93 or higher unleaded octane? or just adding a little racing fuel to the tank too? I believe E85 has lower power figures and worse gas mileage.

Sweet car! You need to come up to Interstate so we can watch you spin out;) (on the street nights anyways)
I prefer to keep it on the streets.:D

Thats cuz they all see your FMIC from two miles away and RUN! Nice car, nice setup!

There is no life over here. I can't find any thing to race. Once i get new axles i will be traveling for some action.

It made 472whp and 360tq on a dyno dynanmics machine on 24psi. Dyno dynamics dyno's read lower than most. Its comes out to about 527whp on a dynojet. This was on E85 fuel. Would have tuned on more than 24psi but the greddy Profec type S wouldn't go any higher on the 10lb wastegate spring.
