Chris they have the benefit of 93 octane so i can see 20-22 but 25 is reaching. Were stuck with **** 91 and 17* of timing. The meth on my old lsj helped alot. 24.5*

 

let me guess you had enough nozzeling you could back off the e85 slightly and compensate with the meth thus lowering the duty cycle but you can still say "i ran 60s and e85

 

Ok I didnt see stock pulley, I guess I see pump gas cars around here hating timing due to high heat and **** gas. Still 25 is a lot.

There is no hassle, if you have the injector why not use it? Its kinda a free mod, you have to fill up, why not on E?

I have not only felt high end power I have felt power through out the power band. I really didnt feel the same on pump gas. So the "few" extra horse seems to be worth it.

Actually this is straight E, his meth was out of the car.

Yah I know. I realized that when I was typing my other post as you can tell.

 

Maybe because most of the "community" that are telling you it cant be done havent touched a laptop and couldnt tell you what cot, pe, sd, lamba, advance even is. You should know this.

 

The meth kit is off my car. Read my for sale thread. We have tuned without it since I started running E85.

Nice

 

Please stay out of threads you know nothing of. You tried e85? Go buy a cobalt and hptuners and dick around for a little while then come back.

 

Tis a hassle to route your route <- 2 different pronunciations around picking up e85. personally when i get my work vehicle in a few months i'm gonna get e85 just cause I won't be driving it everyday and there is a station a few blocks away. then the next closest is like 20 miles away. I just can't wait until e85 becomes even more widespread.
Is also a hassle because of the different blend changes and having to tweak for them...

 

So you do know what youre talking about. You just come off as a dick in every thread. LOL

 

I can agree the only hassle I have is location........ but its worth it!

 

Its amazing how once again a member asks a legitimate question and instead a dick measuring contest ensues.

 

Oh nice sig, I couldnt see it all the way till now.

 

Very worth it!

Yes thanks. I stole it from you

 

Really? You know that is funny. 60's and a 2.8 on pump gas is what like 80% IDC with an 11.5 AFR....So how do you go to a fuel that burns at a higher rate and a .10 smaller pulley and come out with the same IDC? I am VERY curious.

 

On E you can run a little leaner than 11.5

 

And before anyone says it yes the car was heatsoaking like a ************ and yes it was pulling timing, dead IC pump we found out after that run .

 

iat of 45* buddy. You were probably negative da, ton of o2 in the air. We here in Arizona see days of damn near 5,000 da. Less o2, less fuel needed. I know my 60's were NO WHERE near 80 percent duty cycle

 

Which I realize, but mid 80 IDC on a smaller pulley and same size injectors, IDK.

 

My 60's on 2.7 and meth were at 60%.

 

So I guess that that is where the difference lies, I've never had a part in tuning a car in an atmospheric change like that ha. Still like to see a log.

Hmm, so apparently then it's not THAT darastic of a change, considering the meth will free up some IDC, idk but hey if it works for you go for it, not gonna work for 95% of people on here though and I hope you don't take that car out of that change ha.

 

I just wanted to ruffle things up a bit since he IS running e on 60's. I know it wont work for most and when winter comes he will most likely need 80's (60 degree days) but it is still a cool experiment and all of us AZ guys were very shocked lol

 

Yeah no doubt learn something new everyday . Wish our winters were 60 deg days LOL.

 

I will be getting 80's once my meth kit sells. Well put Brett.

 

Dam you guys stayed up late working on this! lol

I agree with slowguy with a couple of differences.

Powerwise
You are not going to make that much more running a 3.1" pulley on E85 vs running a 3.1" pulley on gasoline (On a car with proper cooling mods). But there is a power increase. I picked up like 7whp just by switching fuel on a 2.8" pulley. So on a 3.1" there might be a few ponies in there.

But I would be willing to bet that on a basic Stage 2 car. IE injectors and pulley, no other mods, that I could make at least 10-15 more hp with E85 or gasoline. E85 is a cooling mod. It burns much cooler then gasoline and controls heat much better.



I lot can be done with a good tune. I tuned a Cobalt to 291whp with very basic mods. E85, 2.9", HE, exhaust.

Reliabilitywise
E85 is totally worth it. Like I said, it burns cooler then gasoline therefor it is less hard on your engine. It maintains engine temp and exhaust gas temps so much better then gasoline.

Costwise
This is tough. E85 is about 36% cheaper then gasoline in my area. Running E85 is going to cause your fuel economy to drop by around 30%. So for me it is worth it. You need to determine the cost different between E85 and premium fuel in your area to see if it is worth it for you.

Well ZZP did it on their first E85 setup. 60# with their BRFPS set at 70psi. Or a return style system like mentioned earlier.

But I do not think there is anyway to supplement enough fuel with Meth injection and E85 with 60s. That seems like a huge stretch.

 

^^^ Well put.

 

To the OP, definately get the 80's. The cost difference is very minimal compared to the 60's and the 80's also give you a larger range of pullies that you can run.

Eric I know that you know the story of why I am running the 2.9 but the original plans were to run a 2.7. When I went to take the 2.9 off only one screw came out and the rest rounded out because I over tightened them 2 years ago.
