    Default E85?

    I have a filling station 20 minutes from my house... Is it worth it to set it up to run on E85? What's involved? What are the pro's and con's?


    Basics of my engine...

    BBC
    Iron square port closed chambered heads
    Forged bottom
    TRW 12:1 pistons
    Tunnel Ram
    Holley 660 Center Squirters
    MSD 7AL2
    MSD Pro Coil
    MSD Pro Billet

    N/A for now.... Nitrous later this year. Anything from 150 up on the shot size

    Good post!! I've been thinking the same thing, I was going to ask the same question! I take it you use race gas now? I have a few stations around me also that are on the way to the lake(s).

    I found an informational website the other day.. www.raceone85.com and there are couple forums for it, although the performance one is small with little action.. www.e85performance.net and www.e85forum.com

    Hopefully someone here has more boat oriented insight! I will definitely be watching!

    I've never started the boat so far, it'll fire up for the first time for me in a few weeks. I bought it with spun bearings. The previous owner says he ran it on pump gas.

    I hope they don't do away with it, I just bought two new E85 carbs and looking into fuel pumps. hope to find out if I like it this summer. I like the 2.70 a gallon over AV gas @4.00 or race fuel @ 7.50+. Even at 30% more fuel AV @ 40.00 for 10 gal. E85 @ 35.10 for 13 gall, or 30% more and still 105 octane out of the pump.

    Ok here is my 2 cents.
    good or bad.
    this is my list
    105 oct..wohoooooo
    does burn faster so you use more!!!
    is cheaper to run..
    but you do have to change the carbs or parts in your carb it does eat stuff up..
    never let E-85 set around it does draw WATER!!!!
    and when you do let it set drain the carb or carbs bowls
    I would never mix E-85 AND GAS.. THERE IS NO SENSE INTO IT..you loose the oct..they are totally diff fuels..
    it will make the motor run way way cooler for sure..
    and fars as them stop making it that is news to me!!!!
    rember it is CORN (there is not much oil in corn)
    the bottom line is I would run it and I DO.. the other thing is well in a boat if you are playing on carring your own fuel like I do no problem cause I will only run in short area
    but if ya run like all day long plan on goin back to your landing to full up !!! You will brobbly never see it a boat gas island because it will draw to much water from the humity in the air.. from setting in the gound to long..
    well that is my take and good one to post..
    I plan on running it in my twin turbo nova and i dont have to run a iner cooler because it runs that cool..
    If you do run NOS use racing gas in another tank to spay the sause and the racing gas witht the E-85 will help thing not blow up..you motor if you no what I,m trying to say..

    Default e85

    Isn't it also corosive & doesn't go to a vapor under 65 deg.f. It won't burn in winter conditions.

    Default E-85 or not

    First off on consumption...ethanol produces lower btu when burned so you have to burn more to make power. Main concern is it doesnt like to sit around. It will turn into a gel in the carb. A friend of mine built an ocasional driven street strip e-85 burner and he has a lot of problems with the carb. But it is cheaper than race gas. From what I have seen...I'll pass on the E-85

    Didn't sound right to me either, but my girlfriends Dad owns a 19' Centurion Pickle Fork with a 12:1 468 in it and it runs on pump gas. He says you can get away with it because the engine temps are only around 120-130 degrees.

    His is aluminum headed though. Does that change anything?

    Yes, my understanding is 10:1 on pump gas with iron heads, and 11:1 with aluminum heads. Obviously this is just a ball park figure, alot of other things play a part too. My guess is that he thinks he's up in the 12:1 range. Maybe not, i'm not expert. Sure sombody else here could chime in.

    My guess is the bearings were BEAT to death! 12:1 pump gas bearings no likey.

    dave you'd be silly to not run e85 if its that close, 12 to 1 is a breeze on the stuff and id use it for the nitrous as well, read this link:

    E85 gas and high compression??? - Yellow Bullet Forums

    http://www.yellowbullet.com/forum/sh...85+compression

    as you can see its a beaten to death subject over on yellowbullet, with alum heads the majority will say 14 to 1 with alum heads, 13 to 1 with iron

    Dare to be different, if it turns out great you can claim you planned it that way.
