[QUOTE=MarkoLBR;12339992
So you are saying that when taking ignition down to 16 deg it will make upwards 400 fwhp less??
Regards Marko[/QUOTE]
Yes.. that's what I'm saying....In a turbo car like mine or several peoples that I know of, it is possible to loss out on HUNDREDS of hp in just a few deg. of timing....My own car falls on it's face at 16 deg. and is a rock star at 20 degs... this is that important on some motors......that's why trying to run E85 is sometimes a joke cause you have to slow take too much power out of the car to do it.....maybe some set ups/cars are not as dramatic, but if I put a 1700hp capable turbo on the car...I will not be happy with 800-900rwhp on E85, when I could be making 1200rwhp or more..

I also have never ever heard of people not being able to get in the ballpark with the power they make on e85 in comparison to q16/c16.

but what you just said poves my point even more.
8 gallons = ten races ( just a thereo comment)
so c16 @ 15/gal for 8 gallons is 120
so $120 for ten races.
now lest say it take me twice as much e85 for the same amount of races( which it wont)
so e85@ $2/gallon( high side) x 16 gallons(twice as much) is $32
that is a hell of a difference.

i wasnt trying to say it took along time. just that you had to make sure you didnt do high horse onpump. lol

That's a crazy claim...I've tuned alot of cars and have never ever saw 2 degrees of timing make a 400 hp difference. The most I have EVER saw was 60 hp per degree, and was evidently a sweet spot as the couple before or after it did not make that kind of difference.

I love E85, once you get over the smell lol.
I can keep the engine coolant temps lower, usually under 185 pretty easily in the hottest of days. May get to 190 doing back to back LONG pulls.
I run a stock 140k mi 5.3 with almost 25* and 13-14lbs. I would turn it up even more if I could.
If you dont drive the car all the time, and want a nice cheap safe fuel, use it.
I have zero experience with C16, and not much with 110. I did find that the motor didnt like 12lbs and 14* on our 91, as the first, lower milage JY motor lost a ring land.

We run and tune some FI cars on E85. It is not as good as c16, but pretty close to being as good as 110. I tune it like 100 oct fuel. We have a twin turbo viper here on it and it makes 1060/1145 to the tires. I run about 17 degrees of advance up top at 17psi vs. 23-24 with c16. I would only go to about 900whp on 93 oct.
What difference have you seen in the required timing at idle on e85?
Also, does e85 go bad quickly (2-3 months) compared to gas.
I am working the gremlins out of my e85 setup right now, so any input on this would be greatly appreciated!
Great thread, go corn!!! subscribing!
Thanks

Stabil fuel stabilizer is now advertising their product (or one of their products) as good for E85 and alcohol/gas blends. I haven't got any direct feedback from anyone that's used it yet, but I'm going to give it a shot.
Anybody know anything about it or have experience?

I think E85 hits the 80/20 sweet spot - 80% of the performance of C16 for 20% of the price. They want an arm and a leg for C16 around here, like $15 a gallon!?!
Maybe I'm off a bit but you get the point.
