I know a grand prix has it done, but not sure of the power gains and all that compared to #80's. Everyone on here seems to have e85 on #80's , but I was wondering if it could be done with #60's. If not, please explain. I've read that injectors need to be 30% bigger in volume...

 

need to more about your mods, what pulley you are running will answer your question...stock pulley? i dont see why not...2.8...highly doubtful

 

I don't see why the pulley would matter?? If I wanted to get the most out of it yes I would go with the 2.7 or possibly 2.6, but why not 2.8? e85= higher octane, more cooling, more timing...

 

wont work bra, people on m62 and 2.7-2.8 on 80lb injectors are maxing out there fuel system,60LB definately wont work unless u wanna run stock pulley.

 

you might be able to run e85 on 60's and 2.8 it would be close but no further than that due to lack of fuel running meth on top of the e85 would help a bit but would be cheaper and easier to just go with 80s

 

wait... e85 aside for a sec... if i were to run #60's with a 2.8 I would max out my injectors? at what moment would this happen?

 

Yea dude. . . totally depends on the condition of the car; IE: Stock or not, etc.

edit: late post sorry. You should see in your tuning software at what point the injectors are at peak throughput.

 

you need to use i think about 30% more fuel with e85 then gas that is y you maxed out the injectors

 

You would probably max the injectors around 5000rpms.

There is one guy on RLFs who ran E85 on 60s and the GMS2 pulley. At 7000rpms the IDC is in the high 90s. Like 95%

You really don't want to go any higher.

 

to put it simply. fueling is dependent on air flow. stock pulley=smaller amount of lbs/min of air than a 2.8 pulley. which means idcs on a stock pulley will be way lower than on a 2.8, meaning you will have enough room in the duty cycle to switch to e85 on 60s on stock pulley. do that and see where you're at when the tune is finalized. if theres room, drop to a 3.1 or 3.0

 

awesome info ebristol! the guy even posted his tune file that he had for the 3.1" pulley and #60's.. sweet!

what kind of whp can you expect with a 3.1" #60 injs. full exhaust 3", cai, cobra h/e?

I think it would be awesome to run e85, but if the power would be around the same as a 2.7" than I probably wouldn't waste my time.

 

my buddy, smthomas is running a 2.7 and 60's on e85. His car works just fine. He is tuned by sccobaltss I'll see if I can get him to post up in here and show logs

duty cycle is mid 80's iirc at 6800

 

Can you **** a hooker without a condom?

The answer is maybe, but the risk is not worth it.

 

buhahahahha no way.
so much fail in this thread.
IMO 60s and e85 is not worth it. If I can pull 20-25 deg of timing off of a 3.0 and 42's with dual pass, h/e, and option b, why go to a higher pulley and e85 to go slower?
If you're gonna do a 2.7 and e85 pay to play and get 80s.

 

maybe at 17:1 afr

 

and return fuel system

 

what is your definition of "fail" in this thread? I had a legitimate question. Don't be an *******. and yes I probably should just get 80's..

 

No way people are running 80's and maxing out. I am on E85 with a 2.8 and I am no where close to 95-100%.

This is correct. I have tuned a 2.7 m62 on E85 here in PHX and he was seeing about 78% at 6500 rpm. I need to work on the AFR's a little bit but that little bit should not max them out.

 

i understand your question. but if you were planning on dropping to a 2.6 or 2.7 get 80#'s. the only reason i'd EVER run E85 on 60's is if i was wanting to get every pony i could out of the stock pulley and make some records.

 

my reaction was no way as well, i wouldnt just lie on a forum to impress people when its not even my car im talking about

 

I wasn't talking about your question it's a legit one that hasn't been posted on these forums before. I was talking about some of the answers.

I forgot about elevation differences I guess? I normally think CO for needing less injector I guess AZ is up there too. For us normal elevated people however that is impossible.

 

20-25 degrees of timing is a big stretch of timing which one is it? You kinda cant have both. That is kinda hard to believe anyway. Plus on E85 you can go 25 degrees all the time at a higher afr to achieve more power.

PHX is not high elevation. 1100.

 

Youre not gonna max your injectors on fossil fuel with a 2.8 and 60s

 

Its true it can be done and it has on my car. This was an experiment that we tried on my car and we were shocked. As soon as I sell my meth kit, https://www.cobaltss.net/forums/parts-66/sale-devils-own-progressive-meth-kit-223316/, (shameless plug there) then I will be purchasing 80's for more headroom.

 

I'll let you know when I get adventurous enough to get to work on that Need to fix my WB 02 first and I am teh lazy cause I just DD the car right now so no real care atm...Should be able to pull 20-23 no problem 25 if my car loves the timing as much as it has in the past...I ran 25 deg timing stock everything except an intake, don't really see it being too much of a leap with full cooling and only a 3.0. Right now I only have it at like 18 deg....which is what straight up ott 2.8 and 60 cars run lulz...
Hard to believe? Why's that? Boosting 13-14psi IAT2's reaching maybe 140 after multiple pulls, engine coolant never seeing higher than 190.....yeah you get the picture.
E85 you are also running a larger pulley so in the end sure maybe you get a few more horses, but a few more hp isn't really worth all the hassle .

Really don't see that happening when the whole rest of the community can't do it.....weird.
