we haz 100 , 103 and 107. mostly 76 gas stations carry them ^_^
but they r like 8+dollars a gallon.....

 

atleast you have options. on base we just have 93. closest E85 station is 60miles. and back in my hometown. 91 is the highest.

 

e-85 FTMFW!!!!!!! i got tuned on e-85. i had a bad fuel pump when i got tuned but didnt know at the time, we could figure out why my fuel trim was diff every pull and still managed 316whp lol and that was on a stock down pipe and 2.5 exhaust. i was gonna go get retuned but im just gonna do that after switching to turbo soon

 

Lol yeah I know there are others, but near me it's either 100 or 110, or I can get aviation fuel for dirt cheap since I know someone who fuels the planes LOL. I pay $8.99 per gallon.

 

e85 ftw!

 

We've got a 2.7 pulley on for the dyno runs.

It's a mix of regular gas and ethanol, and has an octane rating of about 108. It's called E-85 because it's (in the summer) 85% ethanol (as opposed to E-10 which is what most gas stations sell, in other words gas that has 10% ethanol content). E-85 is not always 85% though, in the winter it goes to 70% ethanol.

 

Yep, same here.

I run CAM2 (Sunoco 260GT100).

 

simple question: since im an 05 will i need a better fuel pump to run E85? or can vince tune around it?

 

i ran e-85 on the stock pump but i had 80's and a return style fuel system. but i ended up upgrading fuel pumps the other week and the wiring kit for the fuel pump

 

If you're on the stock fuel system, you should really upgrade the fuel pump.

 

do think that would be 100% neccessary in my 07...i have the fuel pump rewire kit on now and want to do 1000's only cuz im gonna go to a 2.6...

 

I dont think you can tune a 05-07 pcm with a dual tune like you can with the 08-10's... Now if you had HPTuners then obviously you could have both tunes but I don't believe you can with just an 05-07 PCM.

 

Technically, this was accomplished with GMS3 (05-07' SS/SC's) years ago.... You have your standard (default) 93 octane tune, and you have your second tune for race gas by flick of the cruise control button.

Recently, Trifecta has taken that a step further, and has been able to provide some level of customization to the mix.

 

I hope you aren't puttnig aviation fuel in your car though. Aviation fuel is basically Diesel with different additives. And it doesn't have the cooling or lubrication properties that diesel has.

 

Aviation fuel..... no no lol.

 

i have just 80's at the moment... ill prolly get the fuel pump on OTTP... im just gonna run E for one night well see how it goes

 

what she is talking about is avgas (avaiation fuel) not jet fuel avgas is for high altitude gasoline aircraft engines it goes back before ww2

 

Great info i will be running.trifecta stage 3 aswell but will use racegas due to huge lack of e-85 stations
What is the ideal race gas for gmstg3?

 

I have always ran Sunoco 260GT100 (CAM2). It's 100 octane unleaded. Goes for $7.49 /gal in my area.

 

im excited to run both E85 and RG should be fun

 

doesnt e85 and race gas provide the same cooling? i thought the higher the octane the cooler the burn? i guess i got more reading to do.

but i guess if you need more e85 than gas, then the more liquid would provide better cooling.
