^^ This is my plan atm. Because EZ-Mode. Of course I NEED E85 to actually happen out here, but you get the idea.
If you ever meet 18psi IRL, he smells like E85.

 

I currently have a "rich switch" on my dash to switch between my regular map, and another map that's about 15% richer.

I was using it for hot restarts and things like that... but I have been dialing in my MAT correction table, and I don't run super lean on restart anymore, so that will likely become my "fuel type switch" here in the very near future.

Doing timing belt/fuel pump/engine bay cleanup this weekend. I recently ripped out A/C, under hood evap stuff, and that uncovered some of my rats nest from my HID install. Moving those bits to inside the fender, also removing the passenger frame rail mounted fuel damper, and just general cleanup.

I'm falling so very, very in love with this car.

 

I have been thinking about doing this for a track map. We used to add some fuel in my subie before track days. It would be nice to have a table switch for that. Any pics?

 

Why would you want to lose power for a track day I think proper dyno tuning for fuel would be a better idea.

 

Well on my old setup it was to preserve the engine on hot days. I am no where near pushing limits on my car anyways. So a little insurance is never a bad idea (for my setup).

 

Do we think the walboro is necessary for ~200whp on E85?

 

Welp my stock pump wasn't for 225, so.....

 

Hmmm, shopping time.

DW is quiet but slightly more expensive?

Walbro is loud but a bit cheaper?

 

shoulda just bought the dw200 from me that I returned to Bryan@Fab9.

I like the dw200.

 

Did your pump die or run out of capacity?

 

Didn't die. I honestly don't even know if it truly ran out of capacity, but I know for sure I was overwhelming it from time to time. I think it was mostly temps that would cause it: on a hot day it'd be fine, on a cool morning or evening it would miss the target afr by about .5-.8 afr too lean

target afr is 11.9-12 boost is 10.8-11.3, and VD puts me at 225ish

 

I guess fuel pumps are so cheap it doesn't make sense to risk a motor over $90. What will a DW200 be good for on e85? Should I say **** it and get a DW300?

 

IMO anything bigger than 255lph will overwhelm the OE regulator. some even say that's too much

ive had good luck with dw200 so I stick with it. i dunno

 

So you're saying I need this too....

FUELAB 515 Series Fuel Pressure Regulator - fab9tuning

Crap, this isn't going to end well is it.

 

Ok, overkill need to back off. So a DW200, will it overpower my 90-93 regulator? EO2k, have any links about the overpowering?

 

Big maybe, I wouldn't chance it. If you're cheap just run a Walbro 255 for the headroom. For science I just ordered some ID 1000s an a Walbro 255 for my Rotrex car, time to get off the water we call 91.

 

Fab9 price difference is like 18 dollars. I need to hear what a walbro sounds like.

 

+10* everywhere
....basically

You're gonna love it

 

I can't wait, I ran E85 for a year and a half with my N/A set up already. I just switched back to 91 for the Rotrex install and to get a baseline, again for science. I have a 3 year old junkyard 99 motor with a BP5A cam...I suspect it won't last long if I go for all of it with the tuning.

They do whine a bit, but it's nothing that would stop me. If it was a street only car and I cared about noise, I'd get a DW.
