How high are you guys running your AFR? E85 isn't like gas, max power is in the low 11s rather than gas's mid 12s. Mine is running a little richer than that right now anyway, which would explain part of the high IDC.
I run my base at 50 psi. My afr was actually in the high 10's gas calibrated afr. Both my pumps run parallel in tank. My system seems to have plenty of fuel so I'm not sure what the differance would be. My injectors are low imp 1250cc. I'm running a stock 05 sti fpr but I'm pretty sure its not being over ran because I run a fuel pressure gauge also and it seems pressure rises 1:1 on the gauge. Perhaps your getting voltage loss somehow to your pump. Or maybe your making a ass load more hp than you think .

I'm sure I'm near the limit with my 1000cc injectors & GT3076, will check when I get the car back.
I already have the 255, they are recommending the dw300 FP. And 1000 injectors before they will tune the car. But it's money I don't have to spend. (Since I already have the 255 and the modded blue injectors)

Anybody else, what are the fuel requirements for e85 and a VF48 turbo?

What is the flow of your light blue modded injectors? I imagine around 850cc...
That is more than sufficient for you VF48. Who is going to tune your car? If they are recommending a bigger pump and 1000cc injectors for a vf48 I may stay away from them.....

My walbro 255lph was good to about 480whp...

Draco, I have a free dyno tune. Which I know them well, so I trust them. They just said the dw300 was designed for e85.

And I have not had the injectors flow tested, but going off from here they should be around 740cc.

I had my 255lph in the tank for 4 years, I pulled it to install my walbro 460lph. The pump looked like new and there was no rust what so ever, I sold it and its currently running on someone else car .

My old light blue modded injectors used to flow 860cc, I have a set of stock light blue injectors laying around that I can sell and you can modded them. I hope they are not trying to sell you id1000s they only flow 860cc...

Since its a so call free tune they are trying to sell you something that you don't need. 740cc will be enough at our elevation.

Magnafuel has nice ethanol/alcohol compatible filters as well. Summit sells them, or you can probably call magnafuel direct and order.

Yeah - this is the only distributor I could find and they are out of stock on the 5/16th barbed fitting one.

When I go with a bigger turbo, I'll do my fuel system and switch to AN fittings but that's not happening real soon so I need to find something with hose fittings.

I emailed Golan to see where I can get one.

I'd love to find a filter with a clear case so I could check it without opening it up but such a thing doesn't seem to exist.

--

On a related note: For people with the 08+ WRX/STi and older Legacys that have the white fuel pump housing - have you ran into any issues with E85 and the built in paper filter that lives inside that housing? I didn't see a way to remove/replace it. Could this be an issue with extended E85 use or should it be fine?

Cool Looking for blessing/comment from your experience.

Hi Guys,

Here is my build idea. Nothing has been ordered yet though...

Car: 2011 STi Cobb Stage 2, catless Invidia DP, stock catback.

Deatschwerks DW65c (Flows 265 litres per hour, Fits in cleanly, no modification)
Deatschwerks 1000cc Top Feed Injectors
NGK 2309 Spark Plugs
GrimmSpeed EBCS
AEM 35psi Boost Gauge
AEM Digital Wideband UEGO Gauge

Daily driver, not looking for a rip saw. Want it dependable and between 300WHP/WTQ and 350WHP/WTQ on E85 tune.

Please be constructive as well as honest.

Thanks and regards,

-J

^ you should have NO problem hitting/beating your goal...will more than likely be WELL over that goal in wtq


just fyi...the ngk iridiums have been known to have issues when running E85. i would recommend going with the ngk coppers. the part number you are looking for is LFR6A.

Thanks Amalgrover,

What kinds of issues, bad stuff like preignition? Is it because the coppers are hotter?

Regards,

-Jim

some people never have issues with them, but alot of people have had issues with the iridiums misfiring and fouling out faster than the coppers.

Understood, thank you!

On another note, what is going to happen to E85 with the drought situation?

Skyrocketing prices? Shortages/production cut backs?

I live in Wisconsin and we have an E85 station about every 500 yards. We're absolutely a corn state. It's pretty bad here but we're no where near as bad off as some of the farmers to the South and west.

I've noticed a lot of our E85 stations around here disappearing (renew E85), but you can still find E85 fairly easily.
The prices are the drawback. It's not much cheaper than regular unleaded recently, but it's cheap compared to race fuel.

Hi Mark, where are you located?

Kwik Trip and PDQ are in for the long haul. So they say.

I have a Kwik Trip 1/2 a mile from me, a PDQ 1/2 mile from where I work, and there seems to be a station near all the autox/track events I run save for AIR in Shawano and Blackhawk Farms.

E85 prices are up in the Des Moines area. They were down as low as 2.68 I think but are currently hanging around 2.99. Premium for comparison is around 3.59 right now. At a 60c difference, it costs me just slightly more to run E85 than premium when I average around 16 mpg. I can get about 18.5/19 with all highway and save a little money running E85.

Our E85 has gone to 70% ethanol everywhere though, probably to keep the cost down. Last year we were seeing around 90% at this time when gas prices were way up.

I'm headed to Denver, CO tomorrow, running E85 the whole way. I've got a Zeitronix ECA so I'm going to see what the E content is as I fill up along the way.

If your converting for price over performance, you doing it wrong. Besides most of us need 93 octane. Where i live, E85 is about a dollar cheaper than 93 octane. If i put regular in my car, my engine will tell me to go f**k myself.

Haha - I assume you mean the price difference and not the E content right?

Yup - that's the one I have and its been solid so far. I've had in for a couple weeks. I snagged the needed sensor for cheap from a Tahoe sitting in a local salvage yard so my total cost for the project wasn't that bad. Its one of those things that I've spent money on that I really feel like was a good investment. I was always worried about drastically changing blends or pumping in a bad mixture, like only 30% E or something since the regulations are so poor and they know that a true FFV wouldn't be hurt if this happened. I didn't want to have to always get a sample of fuel and test by hand. The only reason I didn't do it sooner was that the cost for a new sensor is really high, higher than the ECA itself. Once I realized I could find a used one and was able to get it cheap, I was good with the price of the ECA itself.

Here's how I mounted everything in case you're interested since you have a GR as well:

Edit: If my fuel lines / FPR look funny to you, its because I switched out my stock FPR with an '05 STi FPR.

Obviously we know about the advantages of E85, hence the reference to race fuel. No need to be a dousch.

jayoung: I'm in Neenah, we've probably seen each other at an Auto-x, I drive a SWP 07' STI. Used to drive a WRB 02' WRX.
I usually fill up on E85 when leaving Appleton for Shawano, but I have taken a 5 gal. gas can with me before to be safe.
I'm not running E85 on my STI, but my WRX was on it for a long time before I parted it out. It's hovering around $3.12/gal. currently, with premium around $3.65/gal.
That only puts E-85 at about 15% cheaper, and with a drop in mileage of about 25% you definitely aren't coming out ahead from a monetary perspective.

Looks good, what kind of plumbing modification did you need to get the 'hoe sensor in?

Not trying to be one, hence the reference to premium fuel. Which is what most of us use.

Why are you converting then?
