tee2 Posted February 25, 2011 Report Share Posted February 25, 2011 so as long as the fuel system keeps up what kind of additional power could be had if our cars were tuned to run on e85. its available all around where i live and wanted to look into it if it would provide additional pump gas streetable power. would a differnet oil be needed or a top end lubricant?

stkjock Posted February 25, 2011 Report Share Posted February 25, 2011 depends on how much you are willing to modify. Lethal Performance has a 2010 GT 4.0L Whipple, fuel upgrades, built motor, full exhaust (cams and heads I dont recall) car made over 1000 to the tire. My car has pulled as much as 960 to the tire at 24psi with a 4.0L Whipple Speed costs money............. how fast do you want to go??? Link to comment Share on other sites More sharing options...
DubbsFaris Posted February 25, 2011 Report Share Posted February 25, 2011 There is an '03 Cobra R that just got converted to run e85 in my area, so I do know it can be done on those engines, and she is getting over 700RWHP. Link to comment Share on other sites More sharing options...

frydguy79 Posted February 26, 2011 Report Share Posted February 26, 2011 and plan on cutting your fuel milage in almost 1/2 too or just doubling your trips to the gas station which ever way you want to look at it! for e85 to be cost efective it needs to be priced @ 75%+- of regular no alcohol 87oct if it's any higher than that your getting screwed Link to comment Share on other sites More sharing options...

Fuel mileage is reduced 25-30% in general for the same type of driving. I've gotten 16mpg for straight highway cruising, average about 11-12 in my mixed driving with spirited WOT pulls. That's vs the EPA rating of 15/20 Additionally to compare E85 to 87 is foolish in a Shelby for these reasons: 1) even stock it requires 91 minimum 2) most get a tune for 93 octane 3) if your tuning for E85 your going for POWER! not economy. I currently run 19# of boost and could easily bump that to 24 and make over 900 to the tire. 4) most of the time in my experience in NY E85 is about 25% less cost.

Not too big of a difference, I chose to compare it to 93 as that would be what I would run if the car was not converted. So to 93 its about a 73% differential. However, to compare E85 to 87 for a Shelby is not a fair comparison. Compare it to 91 if you must for our application. Again those who convert to run E85 can make C16 like power (or more) at a fraction of the cost and with a great leap of convenience. C16 is $12-14 a gallon vs. $2.79. For me I'd pay the same as premium for E85 as the car can make big power and that is the sum and substance of why I own it. Now whether or not E85 is a economical product in the end is not part of this discussion, that is better left to a political forum. Link to comment Share on other sites More sharing options...
texray Posted February 28, 2011 Report Share Posted February 28, 2011 E85 - Bend over America, you are going to enjoy this...again. Politicians and lobbists will be the death of this great country all in the name of greed and self-promotion. Link to comment Share on other sites More sharing options...
aonebadbone Posted February 28, 2011 Report Share Posted February 28, 2011 turning corn into fuel is a bad idea. just look at how much we use corn for and how much the price of corn has increased. Now translate it to you're wallet and see how much it will cost you to feed you're family. What is wrong with gas By the time you spend the money to convert you're entire fuel system to burn this crap you would have spent most if not all the cost savings. Dont forget to include the labor even if you do it yourself time is money. Don't waste you're money or time. If it was so great than every body would be doing it.

2kmelat Posted February 28, 2011 Report Share Posted February 28, 2011 And just think. Even though most of u are not using this corn shit in our car we are still paying for it. why do u think it is so cheap. I guess thats why Ill keep my old 7.3 I still can run my crude oil in it.

stkjock Posted February 28, 2011 Report Share Posted February 28, 2011 can we forget the political issues around the way ethanol is produced in the US and stick to the aspects of the performance of the fuel in a boosted application? please? E85 ~ 105 oct, burns ~ 200-300* cooler then gas. this allows greater boost levels and more timing. if you are content running 93 and 15-17psi, nothing wrong with that. However some of us who want to push the limits and make 800+ whp are using E85 because of these benefits. Lethal made over 1000 to the tire on it. Many guys with boosted applications are moving to the corn to see big power numbers. Link to comment Share on other sites More sharing options...
