Yeah with pump gas its doable but difficult. Its not too reliable to make that much power on pump gas without spray. With e85 it will run cooler which will allow you to run more timing and a leaner AFR (actually richer due to the different stoichiometric value) but the equivalent to leaner on normal gas. So basically you can tune more aggressively on it like you can on race gas. At least thats is my understanding.

 

agreed. anyone know of anythign else that would hinder a e85 swap?

 

im actually getting ready to do it myself. im pushing the stock pulley as far as i can before i pulley down, and this will help get me further. e85 has a higher octane rating, 105 i believe it is. we all know (at least i hope) the higher the octane, the more resistance to knock. therefore, you can make a huge bump up in timing without detonation due to the higher octane. also more fuel is being added to the cylinder, so in theory should help keep cylinder temps down. as it stands right now, if anyone is looking to switch to e85 for mileage, dont. while the price of e85 is around gasoline, you end up using on average 40% more fuel, therefore, costing you more

 

so what all are you doing parts wise to complete your swap...

 

injectors and a tune. thats all that should be needed. seals and fuel lines should be fine for use with ethanol

injectors will be needed because of the amount of fuel needed. im going to use 60 lb/hr injectors. but keep in mind, this is on the stock m62 pulley. smaller pulleys will need larger injectors accordingly

 

im running the m62 for now on a 2.8. when i break down and buy a TVS ill prob be running 79s and a return style along with e85 if not e95

 

79's probably won't be enough for TVS and E85

 

in whatever modifications you do, just remember when switching to e85 you'll need to push about 40% more fuel than you would with gasoline. so just plan ahead and do it right the first time.

+1...........

 

Agreed... e85 is pretty much a cheap race gas but you have to dump a ton of it to make the power, unlike conventional race gas... but i personally know tom aka wickedss and he was running the TVS with 60lbers for a little while and it was fine so i wouldn't see a problem with running the 79s and a proper tune for the e85... and yes higher octane fuel allows you to run more timing, i just hope you plan on buying the supporting mods to get the full potential out of that motor

 

This is cracking me up I posted this question a couple of months ago and everyone and i mean everyone shot this thought down about running E85! I think it a great way to push the stock pully to its limmets. Im going to do this as soon as i get the money but everone was telling me dont waste my time just run meth same gains pluse keeping mpg. Keep us pore people posted on your findings

 

oh everything is bought to be FULLY built... most all my machine work is done or almost done including my ported head and sleeves. its gonna be raw... as for e85 im still kicking it around

and justin what part of indiana are u in? like whats your town close to? im way up north by lake michigan

 

Daily driving it's not a good idea just because it'll cost more. But for racing, it's amazing. Think about it, 105 octane fuel for ~$1.70-1.80. The extra timing would be a nice bump in power.

 

yea this is by no means gonna be a daily driver. it was tricky to drive last year, its gonna take some learnin this year as well. lol

 

I am in seymour IN right in between Indy and Louisville KY on I65 are you going to try to come to the meet in Indy next weekand we are going to a place that has a dyno so we can do some pulls?

 

my block and head are still in the machine shop. i dont even have pistons or bearings ordered yet. unfortunalty i prob wont be together till late april or early may due to my friggin pile of bills that i have staring me in the face...

 

ive been thinking about maybe doing this myself

 

spike how long till u get ur ride back together?

 

idk.... im waitong on my trans. to get done & my head gasket 2 be made then i should be able 2 get the motor back in the car. But then i will still have the charge pipes 2 make, the exhaust 2 make, the radiator 2 be made, and tires & brakes 2 buy

 

whos doin the trans work and how much is it gonna cost you? and whos makin your head gasket and why do you need a custom one? what thickness are you looking for? sorry for all the questions im just curious

 

I have seen 1 e85 pump up my way

 

the trans i cant say yet.... the head gasket is cometic but its the .051" thick(sounds crazy but it wont change my comp.), so thats why

 

think 60#'s with my 2.8 would be big enough injectors to run e85?

 

maybe but im under the impression its gonna take more than that depending on what kinda power your lookin to make
