E85 for my Coyote?

[oldbones]

Have 3000mi on e85 with stock manifolds and haven't had any serious issues. The only problem is on a cold start the rpm's jump a little at idle, but stops when it has reached operating temp.

I got my new injectors in the mail today. Shaun is sending me a base tune for 93 for the LU47s, then will convert to e85.

So is the consensus that you can't DD on E85 and/or leave it sitting in the tank for a month?

I dd on my e85 5000 miles running it now.

I have had my car sit for 2-3 weeks at a time with e85 and dd it for awhile. I have two tunes and switch between e85 and gas. I wouldn't put the car up for the winter or longer than a month or two with e85 sitting in it, it will absorb a ton of moisture.

Gotcha

^Same here with about 8000 miles on E85.

I'm running long tubes and I let that stuff sit for weeks, no issues.

Good to hear. There's a station 2 miles from my house so I'd have to do it. Car actually won't be a DD for me though, will probably get driven once every one to two weeks.

Awesome! Thank you so much! Gonna have VMP tune for E85 and luckily the track has a gas station that sells E85 right next to it. So 47lbs injectors, gt500 fuel filter and gt500 fuel hoses if running NA?

Excellent choice in tuners going with VMP. Justin continues to assist me remotely between dyno tunes. Bustin' my hump to get her on the rollers for E85/N20 tune as we speak.

What kind of gains are NA Yotes seeing from E85 and corresponding tune?

So the stock pump in the 11-14 GT's are fine for E85?

 

[el jefe 302]

Yup, as long as you don't run a BAP.

 

[T's03GT]

I am probably trading for a 2013 soon, and I plan on running E85 as I found a station a couple miles from where my college is. So literally all I need are either 47's or other injectors of that nature? It'll be an exhaust only car till I can afford to boost it lol.

LU47's and a tune is all you need.

 

[T's03GT]

Hell yes. That makes my life a lot easier.

Lots of guys running coyotes with e85 and baps.

I agree 47's and I would at least do a fuel system wire upgrade, cheap easy mod to help the pump.

UPDATE:

So yeah Ive been on E-85 for the past few months. Its GGGGRRRREEAT! MPG sucks but at $2.30, you dont lose out after factoring in the specifics.
93- 280 miles to a tank (14 afr cruising/ 11.7 WOT) E85 180 miles to a tank. (10.3-4 cruising, 8.5 WOT)
Before inj and E85, dynoed on a dynojet 399/375, after on a Mustang Dyno, 410/375 (430ish dyno jet est.) Im not a dyno queen, just wanted a comparison.

Havent been to the track as of yet, but now since I have new wheels and traction, I will make a pass. But have results from racing two of my friends cammed/stalled G8s (45-460rwhp) before e85, theyd put 1.5 cars 40-120, after e85 we are tied at the door handles.
So it works.

Doesn't seem like the additional cost is worth 10 actual hp/est. 30 hp. Wouldn't money be better spent on a plug and play N20 kit?

$3.50 for 93 (and seems to be bad gas around Houston)
$2.30 for E85 (testing E75-E90 is most areas)

This is my DD, I have a 03 Honda CBR1100xx to scratch that itch when needed.

I'm running just the 47lb injectors and basic bolt ons. Car runs great. I switched over because the gas is SH*% in this area. Highest octane being 91, but turns out more like 89-90.
