What to expect if I switch to E85???

[2004cobra615]

Wondering what to expect if I make the switch to E85... I'm toying with the idea. I have been searching around and wanted to verify my findings. I shouldn't have to change much correct... Pulley and new tune? Mods are listed below.

I get about 300 miles a full tank now... I hear you use 30% more fuel so I should be able to get around 200 miles out of a tank?

According to my research I should be good for 700 rwhp with the fuel system and injectors I have...?

Do you guys have test ur fuel Everytime you fill up?

Bitches will come out of the wood work when they sense you have liquid gold running through your veins.

Car might run a little stronger too.

Its night and day man, seriously. And I'm barely touching 20psi from 15-16 on 91. Haven't had a single issue myself.

 

[Weather Man]

On my turbo 3v 91 octane, I went from 598 RWHP to 701 RWHP on E85 same boost of 12 psi.

 

[c6zhombre]

My 18 psi 93 tune on a 2.3 whipple is 560rwhp. My 22psi E85 tune is 714rwhp.

Expectation on a 2.9 whipple swap turned up on E85 would = pain

 

[2000GTSTANG]

A full tank of e85 last me less than 200 miles, if memory serves me correct. I always try and fill it back up around the 1/4 mark too so I dont run my pump dry. It depends on how you drive of course too. I can't keep my foot out of the loud pedal so that doesnt help.

You likely need more pump and injector.

I have 2 on E85.
One is a VMP at 22#'s making 725rwhp with Lethal budget fuel system + twin 465 pumps + 80# injectors. I get 10mpg.
2nd one is Kennebell 2.6 at 22#'s making 695rwhp with Lethal budget fuel system + twin 465 pumps + 80# injectors. I get 10mpg.
But the extra timing allowed with E85 makes the seat-of-the-pants feeling so much more POWERFUL than on pump gas. You will not be disappointed....except with loss of gas mileage.
But as mentioned above........the ladies will flock to you knowing you have corn in the tank.

 

[V6&V8SHO]

702whp
690wtq
22psi
2 465s
ID1000s
Vmp TVS
Lethal 1400hp system

On 93 I’m just shy of 600. It’s night and day. I run the 93 octane low boost until the temps warm up and the E tests good.

 

[NateDogg]

You should expect more timing, boost and RWHP.

I average about 14mpg since the switch.. Really not bad at all.

**edit**

For reference, 2.9 whipple 22# -10 feed -8 return, 465s. bunch of supporting mods, cams.... 720~RWHP

 

[94slowbra1]

more f#$king power, thats what!
i just did the swap. tvs on 21lbs, all supporting mods, fore level 1e with twin 465s and id 1050x. the difference from 93 to e85 is worth whatever hit you take in the fuel mileage dept. my car isnt my daily so i dont care what it gets.
only thing i can see you needing is more injector. maybe, maybe not. take some logs and find out

expect to change ur oil a lot more often and they sell small E85 testers cheap. I would test at ur local pump to see what their actually putting in there on occasion.

we get ours from a gas station and fill up 55 gallon drums but we test it first before we do that to make sure its within range before filling up our drum.

Thanks for all the comments.

As my car is now with lethal budget , 80ilb injectors can I expect 700 plus rwHP? With pulley and tune.

If I have to switch fuel system pumps and injectors I will do this next winter. If all I need is a tune and pulley I might try it this year. As far as I know I'm E85 compatible I just can't Max the power out with my set up. Right?

Switching to e85 was one of the best mods I've done.

As far as having to change oil more frequently, if running a good quality synthetic oil you shouldn't have to. I run Amsoil ss 10w30 and change oil once a year. But I only put about 800-1000 miles a year. Hopefully more this year.

I’d expect a huge shit eating grin from ear to ear that will last for a good week then rejuvenate every time you go WOT. Best mod I ever did. As others have said, you’ll gain a good 100hp by switching over and pulleying down and tuning the setup. Oh and expect to maybe pull the blower off to change injectors too, maybe.

Yes. You'll be over 700 depending on the pulley combo.. I used a 2# lower and 3.25 upper to get over 700

 

[GodStang]

93 Octane I was in the low 700s with the little 2.8L. Went up to E85 same day same dyno and got near 800rwhp with 80# injectors and still plenty of room to go. Some tuners cant tune 80#s so that may be an issue.

 

[2004cobra615]

Okay so sounds like pullying down and tune and should be good to go for 700rwhp.


I'm in Chicago land area and Tim Barth is local seems to have a good name.

Anyone else??

I'd talk to Malcolmv8. He can take care of the remote tune as well as any parts you might need to upgrade.

 

[c6zhombre]

There are at least 6 guys posting on this thread that have an E85 tune from 04sleeper.....pretty hard to go wrong with Kevin. He has more E85 tuning experience than most.

I make 640 on pump with my 2.9 and 770 on E90 Ignite Racing ethanol. It pulls like a damn monster

There arent really any E stations by me, and I rarely run on corn. So the $9-11 a gallon isnt too bad

Gas mileage is terrible. I mean bad. Maybe 8-9mpg? lol
