Guys running E85, what do you think the limit is? 700whp-800whp
In a 13B of course, what do you think the limit of this fuel is? What about with meth injection added?
Throw me some figures.

Will work for horsepower
What im hearing from friends useing e85 is that each fill up changes and there carring there lap tops to alter for the diffrence.
I guess there not station testing like the standard fuel has to be rated and tested!
Maybe its just here but i would hate to be on the edge and get a bad mix!

. It's never consistent out the pump....So be careful. -J

I not speaking fron a point knoledge but e85 is made for flex fuel cars and there designed to adjust to the percentage of gas to ethanol. So it stands to reason they wouldnt moniter it as close as normal gas for the oct rating!
Think about it your running on 87 oct with 1/2 tank and put in e85 whats your rating the car just has to self adjust!
It scares me becouse im no tunner on the run!

You can buy a gauge that shows the % of ethanol you're running. I talked to the owner of the local gas station here, he's only got two blends. I winter mix and a summer mix. He said they're watched closely by the govt, and if they're caught being sneaky they'll get fined heavily.
If you're that paranoid, you can always buy E98 and mix it yourself or just run it by itself.
I don't know about you guys, but I'm not paying $22 a gallon for C16. And, I'm sure as hell not gonna be limited to 93. 93 octane will commit JIHAD on my engine.

Taken from my local 240sx club and consolidated into one quote
They are also saying the cars are running way cooler. Cooler temps+higher octane == reliable high hp.
We switched two of our cars to E85 today and took them to Tony at UMS for tunes. The stock long block RB made 541whp-390wtq and the stock long block SR made 443whp-381wtq. The tunes are flawless, I couldnt believe how smooth they ran. The cars behave just like a stock car would if it made some decent power. The numbers dont do justice to the dyno chart as soon as I have time I will upload them. The SR put down over 350ftlbs of torque from 4200 on and the RB made 300ftlbs at 4500 climbing steady to peak at 6500. Very good work from Tony and great results for two stock internal engines running under 20psi.
It should be noted that tony previously tuned the RB on 91 pump gas and the RB made 463whp and I dont remember the TQ. The only thing that was changed was the injectors were 550cc in 91 pump gas tune. They are now 850cc for E85 this is a net gain of 78whp
The SR was tuned by tony for 91 pump gas and had 347whp 308wtq. Not one single thing was changed to the setup and it now puts out 443whp and 381wtq, for a net gain of 96whp.
Boost levels were changed from 17psi 91 octane to 19psi E85 on the RB and for the SR from 15psi 91 octane to 19psi E85. A realativly small change considering the results.
-------------------------------------------------------------
I get 2mpg less than I did on 91 so now I get 23mpg adverage driving mostly freeway. but I get on it atleast three times each way

I ran across this thread on another forum....back to back with C16 vs E85.....very nice.

He posts the #'s on E85 and later compared to the race fuel #'s.

14psi on pump gas, he made 722rwhp.
14psi on E85, he made 880rwhp
So a 158rwhp pick up !!!!

Two nights ago on a certain application I made just over 800whp through a 3-speed auto running between 34-38psi with a 125hp nitrous shot. Took the car out on to the streets and made numerous runs to about 170mph to check gearing and tune etc.
Went to the local 1/8mile last night and made numerous 6.20's@120's mph passes.
This car been running on E-85 since it was put together about a year ago. It's been through about 6x55 gallon drums of E85 allready and lost count on the nitrous refills.
On all the E85 applications I've done so far I can safely say I've never had to make any corrections frorn inconsistency in fuel supply. I also can say it's probably the most consistent fuel I've used and the results show that also.
Anyone basing the performance of E85 on it's octane rating are not looking at the big picture. Alcohol/Methanol/Ethanol fuels cannot be compared to regular fuels based on it's octane rating. These fuels contain the most important factor when it comes to antiknock properties and that would be their cooling properties.
On a rotary cooling effect is most important than octane rating from my experience. I've seen many different types of lower octane fuels that have greater cooling properties perform better than higher octane fuels with less cooling properties.
Very high compression two stroke racing is proof of that. Any application where a lot of combustion heat is present(rotary engines) fuels that have the greatest effect on cooling the combustion temps. are going to perfom the best.
From what I've learnt in the past year on non rotary applications I can only hope or say the rotary is going to benefit greatly form E85 use. Only time will till. I will be pushing the limits of E85 on a rotary later this week!

you know cris i been thinking about changing over to e85, but y make a change that already works ??????? $$$$$$$ ??????? $3.00 vs $15.00 a gallon i've been runnin 30-35 psi w/ q16 and have had nothing but great results i'm about 2 mos away from beatin up on it for 1 year and still runnin very strong !!!!! damm jus don't know what to do ??????????

Well you could wait and see if it works for me or you could lead the way!
The price for E-85 is a strong point for it's use also!
