Thanks guys, I have made up my mind, and will go E85 route.

Here my setup

Stock engine with bp62 sc 70mm 5 psi & trd intercooler & tensioner & radiator
E/H/I
MS3 (paid, waiting for built by rev)


Few question,

1. Which injector size/brand
1000cc ID?
2. Fuel pump
DW300?
3. Tuning
Anyone in WA area?
4. What else I need?

Thanks & happy new year!!




Car is only for track/hillclimb/tt use, so I would want a safe boost b4 I save enough to buy built from trackspeedenginerring. Just looking for 200whp+ safe power for 2013

Please excuse my noob question,

Thanks you and Merry Christmas

Are you talking e85 vs pump gas? 93 or 91?, or are you talking about c16 race fuels, etc?

Either way, I say for a race car it's a great idea. Especially with a blower, but it seems like you'd want to run more than 5psi as well, which of course e85 will help with.

For a street car I'm not sure. My car is a toy that I drive in the summer, so i'm considering it even on the stock motor and small turbo I'm going to run. But on a race car it should be a no-brainer if it's available.

Yes I am currently using 100race gas

I have no idea what the power potential is for that SC setup, and if it is enough to make 200-225hp then you don't need it at this point. But here are my thoughts anyway.

I don't really see a reason to do it until you have a built motor or need to squeeze every last drop of power out of your current setup, provided it won't surpass the strength of the stock bottom end. It will help some with heat absorption if you are detonating, but it may not be a huge jump from 100oct gas (I have never used that fuel so IDK how it behaves). E85 can get you some headroom for more timing advance, but again that may not be required since you are limited by the stock bottom end, though it could potentially net you some gains under the curve I guess by adding timing in lower RPMs.

I used E85 daily for two years in my last car as a way to substantially increase power over the 91oct tune I ran before that, but I had a mildly built motor that could handle it. 1000cc injectors, a Walbro 255HP, and a fairly conservative tune were enough for 330whp/360wtq from my 4g63.

What ecu are you currently on? I am having trouble believing that you have 550cc injectors on a stock ecu and able to idle. Honestly With 93 octane, proper cooling, and 200hp I see no reason to run e85 or 100 octane race gas. Now with a built motor and a large turbo then the story changes. How available is e85 where you are at?

I hav a power card now,

Btw anyone has 949 email? The botton on their site don't work

Yah.

OP just buy a megasquirt with knock detection and make a little more power safely. On pump gas.

When you do get your MS, log your air intake temps to make sure your intercooler is working well enough.

I know on other blower cars, even already properly tuned on 93, there is significant power to be gained going to e85. I would do it.

I would do it, besides power gain you get the added benefit of less detonation and cooler combustion temps.

TL;DR

Yes.

e85 = win. Just make sure you tune your car to add a good amount more fuel during start-up specially in cold weather. I have 550 cc injectors at 80% utilization, a walbro fuel pump, a small garrett tb2522 turbo, and the rest is a bigi kit with a brain MS.

Making 240 whp.

Hardest part of the whole thing is finding a good e85 station

This is good to know v01canic. I have the same injectors, and i'm shooting for 250whp max or so. It looks like i might be able to pull off 240-250whp on e85 with the 550's.

Now I ask you guys (i'm already HIGHLY considering doing this anyways), do you think its a good idea to go e85 on a 250whp t25 turbo equipped 1.8? I figure it will give me more room for error in tuning, and possibly allow me to squeeze out a bit more power from the tiny sr20 t25 I'm going to be using.

im running a 1.6L and i was able to do it

iTrader: (24)

Which SR20 t25 are you planning on using? The same one that is just about a 2554? If so then I don't think even with e85 you will be able to hit 250hp at the wheels. Also how available is e85 in your area?

Fireindc

iTrader: (13)

Yeah, the smaller one. I think you are right as well, 220-230whp is probably a better goal. I have plans of going to the bigger sr20 "t28", that is very close to a gt2560 eventually though.

Getting the e85 isn't a problem. I live in a small town, i rarely go out of town in my miata. Its more of an around town and canyon carving toy that i "daily" in the summer. I have an OTM. Long trips in the maita could be a problem, but it would be easy enough to flash my 91 octane map on there for road trips.

I have made up my mind on the e85, and just order a MS3 from rev

nuwing

Talking to a local tuner, he said cars upgraded took 80% more fuel on E85 after tune. Never tuned one myself, but that is the headroom he told me to look at when upgrading for fuel.

MWatson17

I thought it was 30%? That's what I found to be the common number. I think my Subaru tune wanted about 35% more for that specific application.

Local tuner doesn't understand how math works.

E85 cars need anywhere from 15 to 50% more fuel, depending on load.
