E-85 Roll Call

Anyone else taking advantage of the 518’s new-found abundant race-fuel, E-85? I’ve been driving my Evo on E-85 @28 ~ 29psi for the past 3 months with great results (440WHP on a mustang dyno). To run it on my red turbo all I needed were 1200CC injectors and two Walbro’s. Stock ECU.

For those that dont know - E-85 has the cooling and octane efficiency of about 110 - 116 octane race gas… and its only ~$1.69 a gallon vs $4 - $5 for race gas. Any car can run it, all it takes are slightly bigger injectors and a retune… no need to replace any other lines. Smells great too :excited

All you Turbo guys who have motors that could run more boost than 93 octane allows should look into it… you can crank that boost up and max out that turbo/motor on every day gas now. Imagine driving around all day on race gas that costs less than pump gas!

There are about 10 gas stations in our area that sell it, pretty evenly scattered to never have to worry about running out of gas. Check it out: http://www.e85refueling.com/

Curious to know who else is taking advantage of this…

Edit: Race gas costs much more than I said above…

I’ll be getting a tune on it as soon as I get the car going again. street class for redline doesn’t allow C16 or any leaded fuel but E85 is ok. I’m looking forward to see what it can do.

Hmm i know a e85 dealer …he sells the injectors and everything to be able to convert it .And he lives in Colonie. I was actually considering to run on E-85 after I fix a couple things.

art, cheapest race gas around is 112 on the pump and its 9$.

C16 is like 15$/gal

You wont be dissapointed - many shops are switching from C16 to E85 not for cost, but for performance.

I think its cheaper if you buy it by the barrel, but I stand corrected… a gallon of E-85 is cheaper than a bottle of water.

I think Mr. Bakerian should run this ish.

7

Does ehtanol smell weird when it burns?

It’d be sweet if it smelled like popcorn.

8

it does smell…

My 93oct map is already retarted but I was thinking about getting retuned on E85. +10psi base fuel pressure should give enough headroom (I think) to run 25-26psi and hit 130+ traps with more knock headroom than I have today.

I’ve heard that the stations constantly mess with the gas/alky mixture and fuel map tweaks are needed often to keep AFRs in check. Art have you noticed anything?

10

Not really fair to compare gasoline vs E85 given they have different stoich.

11

WTF are you talking about… gas mileage?

12

Stations dont mess with anything. Because of the high freezing point of straight E85 gas, gas stations receive deliveries of E70 in the winter, which has a much lower freezing point… ie - more gas, less ethonal.

I was tuned in the middle of winter when the gas stations run E70… so now that they are all running E85 I’m running pig-rich. Yeah ethonal is a little less regulated than gasoline, so just get a little more conservative tune than usual and you are fine.

STFU about gas mileage.

13

Mileage doesnt mean shit when your fuel is half the cost of another.

14

Ethonal smells sweeter than popcorn. It smells more like vagina :number1

15

uhh

16

Nah man, e85 sucks.

17

Comparing amount per gallon is misleading given you need more E85 vs gasoline.

There are people that don’t understand that concept.

Blow me EVO boy. :ahh

18

What if the mileage is 1/4 as much!? :lol

19

Agreed… but no one was really talking mileage here. Talking about cooling and octane.

20

I am not talking mileage. You asked a question, EVO-boy commented, and Beanie assumed.

I just commented that a lot of people don’t realize you need more E85 so comparing cost/gallon is misleading. That’s all. I didn’t mean to spark a riot. :lol
