Hey guys my friend wanted to know what the benefit's are of running E85 and how to do it on his ss/sc he also asked if it is possible to run meth and E85 and if the gain's were worth it. Sorry i don't know too much about E85 and especially on the LSJ. Thanks guys.

 

Well, Ill try, meth acts as a octane booster and also cools the intake air. E85 is like race gas (not sure on octane level but i want to say comparable to 105 octane?), but doesnt cool the intake air. Some say they see cooler intake temps but personally i have not seen cooler intake temps (its freezing here anyways). In order to run e85 you will need 80lb injectors and a tune. You need 30% more fuel when using e85 compared to gasoline. Sorry im a little buzzed right now and I tried my best. lol. Oh and i am not for sure about both at the same time. I would say no but the cooling aspect of meth is a plus when on small pulleys. But the water is what cools the temps. I hope if im wrong someone will chime in.

 

I believe e85 has cooler egt's

 

yes it does

 

to run e85 on his lsj he needs 80lb injectors and a tune atleast

 

alright thanks guys i told him he needed a tune and he already has 60's so i'll let him know he need's 80's what kind of gain's are we talking about here??

 

with a few cobalts with quiet a few mods they have seen nice gains. I didnt get to dyno but i did go from 60s and a 2.8 on 93 octane to 80lbs a 2.7 pulley and e85 and damn what a diff It was and felt

 

Meth on top of e85 is a waste as far as octane. You could probably use it soley for cooling if you wanted.

 

K so if he isn't going to need meth for the added octane what other cooling mod's could be done he already has H/E and stu mod.

 

if he is going to run e85 nah no need for meth really. and up extra h.e and stu mod. all he could add is dual pass if anything lol

 

alright thanks guys

 

Hey Rico, what kinda of timing were you running on the E85?

 

thats a very good ? lol once im home today ill see if i can see that in the tune or logs.

 

Tell him to go E85 hands down. I liked my meth setup but even my meth tune that I worked on for a long time on 24* still felt WAY weaker than my E85 tune that I dont have much time into yet. So far Im on 11.5 AFR and 24* of timing and it pulls harder than it ever has and it is fool proof. If you run out of meth (which is actually pretty hard to do if you have a brain) teh motor can go boom, but if you run out of E the motor turns off (duh since its in your gas tank) so you fill up and get right back at it!

 

LOL ok cool.

This is what I keep reading and hearing. Over all people are liking E85 over meth. I can't wait.

 

And the fuel mileage really doesnt take that bad of a hit. I'm getting 18mpg all in town in 0 degree temps letting the car warm up a lot before driving

 

I cant get more than 15 mpg. My fuel trims are right on and my maf is dailed in and i cant seem to get more than 15. Today when i filled up i got 12...

 

Damn man! The worst I got has been 16.8mpg and thats with my car acting up and going rich all the time at random

 

damn that all weird atleast yalls trims and maf are dialed in tho not mines
