I finally installed my 42.5# Lucas Injectors and began tuning for E85...so far so good, I can run 18.5* timing advance on 13 PSI with no knock at all.

I was told 30% addition to the fueling table is how you tune for E85, so I tried that. Uploaded the new tune, all was good...went to start it...and it would BARELY run. It would idle all wack and I looked out the back of the car and black smoke was pouring out Laughing

So I went back to pump gas fueling tables and it idled fine. Let it warm up, went out and scanned for a bit and holy power batman! I could instantly feel the difference at WOT. Feels like an entirely different car. Looked over at the laptop at WOT and saw 17.0* Timing with 0* KR. So I pulled over, leaned the out the Base AFR vs. ECT table, then added 1.5* timing to the IAT vs Spark Adder and holy shizzle! Saw 18.5* Timing with 0*KR commanding 12.0 AFR!

All in all, E85 seems very worth while to me. $1.39 per gallon for 105 octane, it absolutely kills knock and it burns alot cleaner than gasoline. Although you burn through the stuff more often, it is so cool to blow by people while smelling like corn Cool

I wish they had e85 here.

I was looking at pumps in Oregon, you guys actually do have one. It's out by Forest Grove.

He's not in Oregon though.

There are a couple, don't know if any of them are close enough to you to make it worthwhile.

nope. One is about 1hr away, the other is well over 2.

I am in North Little Rock(or the county outside it)

Ahh jsut noticed that lol

Colorado is blessed....we have over 95 E85 pumps throughout the state. Cool

We have 2 gas stations that sell E85 here in spokane.

I was leaning to convert over to E85 in my turbo car. but in the news the largest supplier of E85 filed bankruptcy due to the very low fuel prices during the winter and lost all sales. So it is unprectable if E85 is gonna stick here.

It's cool to see someone experimenting with E85. I'd definitely like to try it.

There is atleast one in the couve.

I used to know of an 76 station on Interstate Ave that had E-85.

Not sure if they still do.

Got one here in Chehalis. Right off exit 79 on I-5. Been thinking about running E85 in something just for the experience.

It's nice...it's cheap, 105 octane and burns cleaner than gasoline...just make sure you get HUGE injectors. My bigass 42.5# are so close to maxxing out on E85 on about 13 PSI Laughing

I just bought these dammed things and they are too small Evil or Very Mad

I have an extra double pumper sitting around...

Well...

After I read this thread, I did a couple hours of research on the subject of running E85 in factory fuel injected cars. I had read that forced induction cars get a significant torque increase when under boost on E85. Also, cooler running and a low level of knock due to high octane. The problem is the large amount of extra fuel needed to give you a stoich AFR of ~9:1.

So, E85 theoretically needs 27% extra fuel. Therefore, E40 would only need 12-13% extra fuel, and still have some benefits over the E10 gas mandated in Washington. Plus even a stock ECM's fuel trim and feedback O2 system should get me to a decent mixture.

Guess what I happen to have? An '87 5-speed Subaru TurboWagon. This car, when the ECM sees positive intake pressure, exits closed loop and just dumps fuel in until a certain setpoint, around 14psi, where fuel cut occurs. On 91 octane I've had the boost set at around 10-11psi. I run an '04 STI top-mount intercooler, and I have a homebuilt manual boost controller.

Like my Subaru, except mine isn't lifted.

Under boost, on gasoline, this car runs pig rich. I decided to mix up some E40 in it's tank and see how it likes it. Keep in mind this entire car cost me less than a set of tires for my Camaro. Laughing

E40 in the tank, test drive. Boost at 10ish psi. Wow, this runs smooth! More torque even when not under boost. Feels a tad more powerful, still horrendously rich under boost. And the smell... Quite odd. Smells kind of like pouring gasoline over an ear of corn and lighting it on fire. Kind of a sweet, corny, but still gasoline smell.

Anyway, now on to the fun part... I turned the boost up until I hit fuel cut, then backed it off a little bit. I don't have an accurate gauge that goes over 10psi yet, but it looks like it climbs to around 15 momentarily then settles at 13psi. Now it runs like a raped ape! Doesn't smell as rich, no knock, and heaps of power. Me and a couple friends went for a drive that night. My beater car is now affectionately named "The Little Subaru That Could." Laughing

From a roll, from a stop, as soon as my turbo spools I killed my two friend's cars. This was late at night, with absolutely zero other cars around in the middle of nowhere.

One has an '83 Volvo 244 Turbo-Intercooled, which is about 160hp stock. His is lightened and extra boost.
Other is a '95 Cougar 4.6l, which is 205hp/265tq, but 3700lbs. Stock.

Now I know it's not that fast, but it's a decent improvement over the stock 110hp. Next step is bigger injectors and straight E85. Just to see what happens. Wink

Additional info:

Stock boost on my Subaru is 6-7psi.

Stock quarter mile times as tested by a magazine:
Subaru Turbo Wagon - 17.9
Subaru XT Turbo AWD - 17.2
Volvo Turbo Sedan - 17.4
Mercury Cougar XR-7 4.6l - 15.8

This is exciting! Very Happy

Thanks Boostd1 for sending me down this road.

Almost sounds like you have to much time on your hands Laughing

. Way cool you can do that with mostly stock parts. Sounds like a fun little ride now.

This is the smallest pulley you can run on the stock snout...you cannot even stick your fingernail in between the pulley and the snout LOL
