thats true.

and if you don't know what you're doing but want to know, do it yourself and pay the price.

so should I get 550cc for stock turbos? is that would be enough for 15psi?

450 Is enough, but just.
Comes out to 468cc ish for the additional fuel.

I am going to be running some E85 but a mix. Multiple tunes, straight 93, 50/50 mix and straight E85 depending on what I am running that day. But 93 for daily driving.

Just remember it is not going to save you much money, it is only going to allow you to have higher octane fuel for a similar cost to pump fuel.

Draw back is that you will be using more fuel. Don't think that you are going to save all this money switching to E85. It has been proven over and over again that E85 does not really save you much in fueling. But for us and other boosted applications you get high octane fuel that would normally be $7-13 a gallon for similar cost of 87 oct.

The worst thing about E-85 is that it cuts into the sales of water/meth injection kits..... Oh, wait.....

the savings depends on location. here E85 is about $1/gallon cheaper than 87

Actually, I would think that the "worst thing" about E85 is that the production of it has raised food prices by 10% in the past year and it has contributed to raising taxes since the gov't takes our dollars and subsidizes the Iowa corn producers and the E85 refinery process; a losing venture since day One, costing tax payers billions.

But getting back to the issue: A water/meth system that uses 25% meth when under mid to high boost is much more efficient at lowering AIT's and cylinder temps, allowing a few extra degrees of timing without Knock at higher rpms and loads. The water/meth injection is best used for cooling the combustion charge and thus allowing slightly leaner AFR mixtures for better power without raising the potential for Knock. Re: cleaning with water/meth injection, brief jaunts into the injection spray time ( under high boost) cleans and keeps clean the intake valves and combustion deposits on the pistons are less likely to build up for which if they do, will only cause hot spots leading to Knock and/or the most feared pre-ignition potential.

Meth/water injection though isn't used to raise the octane per se but it does have the effect of lowering the volatility of the fuel so Knock potential when compared to 93 octane gasoline is reduced at higher cylinder temps.

I tried E85 in my stupid useless flex fuel Ford F-150 V8 and mileage went from 19 mpg to 13 mpg and oh boy_ I saved 10 cents a gallon for E85 on that loss of mileage? Bah_
Best idea: Take Al Gore's Nobel prize award away because his goofy movie was a predicated hoax, take his fuel hogging jet away, and wake people up to the fact that man made global warming is a myth designed to bolster special interest groups to profit off of people's fears, and we wouldn't have to discuss E85 Ok_ any Iowa farmers can now feel free to flame away.

VIN of your F150? i havent seen any flex fuel F150s yet.

they have other (and better) options for ethanol production but the corn growers cry about it so it never happens.

Truck is a 2006 F-150 super cab, Triton V-8 that comes as an option with Flex fuel in MN.

Wow, lots of miss information there! The VAST majority of ethanol used in fuel goes into regular old gasoline. Now that MTBE is no longer being used, ethanol is the standard oxygenation agent in gasoline. Sorry to burst your bubble there.

I don't run E-85 to save the planet, I run E-85 for the ability to push 30+ psi of boost in my EVO with a healthy timing curve and zero knock

thats why i asked for the vin. i can run it in OASIS and find out for sure.


plus...you dont run E85 to save fuel. thats a common misconseption. as keith said....you run it to take advantage of the octane.


these standard E85 cars out there are a cruel joke on the owners. those of us with the ability to tune in the extra fuel and timing to take advantage of it....no joke.
