no ****....and it would've got walked if it was on real pump gas.

got you covered there sweet pea.

Not true at all, let me explain.

Hope I don't get too technical, i know boosted stuff isn't what most of you guys do.

Mitsu's typically see a 20% gain on E85 vs 93 octane. Because E85's stoichiometric is 9.7:1 it takes 31% more E85 to fuel a cylinder with a given airflow. Because E85 is higher octane and can be run leaner, you don't need the full 31%.

High boost guys typically tune around 11.0:1 on 93, and the equivalent of upper 11s on E85. It's really a lot richer, but AFR gauges read oxygen only, so the amount of oxygen that would correspond to 14.7 on gasoline will actually be a 9.7:1 AFR on E85 even though the wideband is reading 14.7.

Moving on, if you have a turbo that can flow 70lbs/min (not sure what a T67 is but its in the 70s), and 1200cc injectors, which can fuel 50lbs of air on E85, but 60lbs of air on pump gas, you can use more of the turbos capacity on pump gas. Because 93 is lower octane and burns much hotter than E85, you have to take a lot of timing out of the car, which will negate the gains you see from the extra air, putting you at about the same place on either fuel.

I run a little 30R turbo at 30psi on straight 93. My 1000cc injectors get to about 92% duty cycle at the turbos max airflow of 52lbs/min. Because i can only get about 14* of timing at that boost level on 93, the car makes, i'd guesstimate about 430-440awhp on 93. If i went to E85 and more injector, i could easily crack 500awhp.

So on 93, 52lbs of air for me = 430awhp.

If i went to E85 on the same injectors, i would have to turn the boost down because i wouldn't be able to fuel the full airflow. With the higher octane and lower boost i could probably run 20+ degrees of timing, which would mean i could get 420-430whp out of 42lbs of airflow.

When you really look at it, the same size injector will get you to about the same hp levels, but it takes more air to do it with 93.

His giant T-67 is being forced to flow about as much as my 30R because he can't fuel it on E85.

If he put a tank full of C16 in it and re-tuned it, he would probably gain 150whp without touching the hardware. To run E85, he needs some monster injectors (and probably a second fuel pump) and he can get the same gains.

Get that technical bullshit out of SR&K. E85 is pump gas IMO, it comes from a pump and it's not exactly rare.

Beans

I consider it pump gas also, but FWIW, IF your setup is properly supported, you can make the same power on E85 as leaded 112 octane, because it's 105 octane but burns much cooler also.

$3 race gas, i wish we had it in RI.

Within 5 miles of my house, there's probably 5 or more stations, so a lot of the DSM/SRT4/etc. run E85 since we have it around here. Sucks for you.

Beans

I wish, but 93 isn't the worst thing in the world.

It's about 2800lbs, it moves just fine with 430+whp on good ole 93.

I also have meth and race gas if i'm trying to make max power.

I wonder how well my car would respond to an e85 conversion? Has anyone done it here to their NA vehicle?

WSsick

You'd definitely gain some with the tune dialed in, just wouldn't be much. The big benefits of E85 are the 105octane and that it burns cooler. Those are huge for boosted cars, which is why they respond so well to an E85 conversion. If you were running a higher CR motor, like 12:1 and up, then E85 wouldn't be a bad choice for an N/A car but I'd probably leave it alone for just bolt-ons.

Beans

I'd love to see some testing with extreme compression and E85 in N/A applications.

Guys have run 11:1 with 35+psi on E85 and had record breaking results.

I have a couple friends foolin with e85 in old school hotrods. They see some gains over 93, but they mostly use it as a alternative to race gas. E85 is hard to come by around here......definitly not a pump gas yet...If you don't believe me tune your car for e85 and drive it on the east coast. There is'nt any e85 within 50 miles of me.

We have LOTS of meth here in Missouri...no, I don't mean methanol.

Really now? Are you trying to get busted?

Beans

I decided to read up on that a bit. Seems like a huge problem down there, i'd never touch that ****.

In RI, i'm not sure if i could get meth if i tried. We do a shitload of coke though.

Coke and a smile, it wasn't really about the soft drink.

This pic couldn't be more fitting, considering we're the "ocean state"

you would gain some power. but you would also have to up the fuel pump and injectors and a re tune. so not sure if its worth it or not with your mods. Once you go bigger then absolutley!!

It would be better to do a meth injection you get like 15 to 20rwhp and it only costs like 600 for a kit you use your winsheild washer resevoir and it only cost's like 7 dollar's a month to fill it up.
only in MS lol
