is anyone running E85 on their boosted cars?

[learningcurve86]

It made it to the final 4 until it sheared the crank pulley/timing gear off on the line for the semi finals.

Did anyone else notice this? That's just incredible in my mind. Any chance there's a photo of this?

so basically If its below 40 I would have a hard time driving the car. I guess thats not to bad of a trade. I have been looking up e85 station locations all for the past hour lol

One last question otis?? what do you do in the winter when it is e70 instead of e85? Do you have to re-tune your car, or do you have 2 tunes one for winter and one for summer. Last has your car ever not started or had any problems running on e85?

Living in South Florida it's summer year round, haven't really noticed a difference in AFR's.
When it dips into the 40's it is hard to start, but that has to do with the warm up enrichment settings that need to be adjusted.

think they would make similar numbers? I know with meth it should burn like 110ish octane right vs e85 104. Does that sound about right?

dude your the man, and a true innovator in the e30 game!!

question though should I run e85 on my m50
or pump 93 and meth injection

I know with the meth I could fill up at any pump and run the meth at higher boost a similar effect to e85.

also I have 1000cc injectors and I am worried about maxing them out if I run e85

With 1000cc injectors you should be good for over 600whp with E85.

If it's a daily go with the 93 and meth setup.
If you don't care about gas mileage than go with the E85.

Been running E85 for 2 years now on the M30 and love the stuff.
The advantages for boosted engines are:

More power w/less boost
Run more timing
Engine runs cooler
Oil stays cleaner
Exhaust does not stink

As far as fuel lines, I still am using the original tank to pump hose, the rest I replaced since I am running two bosch 044's.
One pump is good for around 430rwhp.

Main thing is larger injectors and enough fuel pump.

req fuel is a fuel constant (pulsewidth adder) used in MS and similarily by other standalone systems. Essentially it's the base pulsewidth for a given injector size matched to the displacement of your engine. by increasing it you can make it run richer without touching the fuel map.

8.3bar?

[einstein57]

I upped the req fuel from 6.3 to 8.3. Worked great with 42lb injectors on 14lbs.

[fiftytakedowns]

you need approximately 40% bigger Injectors for e85 right?

Im wondering what size injectors I should go with for my m10 turbo.

[mkcman17]

einstein57 uses e85 in his turbo car on the track. self tuned and hauls ass.

That's fine. I'll use it as a starting point and go up or down from there. My friend will be helping me dyno tune it and he is really good with tuning. He also has a lot of experience tuning cars on E85 (all V-8's though. Mostly corvettes, boosted and n/a) intact when pinks all out came here for their last (maybe ever) show. He tuned the s/c 1st gen lightening on E85. It made it to the final 4 until it sheared the crank pulley/timing gear off on the line for the semi finals.

[Good & Tight]

It's aggressive so be careful, use it as guide.

[der affe]

Yea if you could post it, that would be a big help!

I am using a s52b3.2 crank (US motor), eagle h beam rods, and most likely Metric Mechanic pistons since they have a turbo design piston that does not have valve reliefs in it.
