It's probably been covered 10 times, but I'm being to lazy to look for it :)

What should one expect to happen with fuel milage if running E-85 with a Carb in a jet boat?

After reading the thread about the blown 557" the thought just crossed my mind if I should try E-85 in the rebuilt 565" running 13:1 compression? I think the problem would be that we burn way to much fuel over a weekend to do run it. They don't carry it at any of the docks at the lower river, so it might just be ruled out before I even start thinking about it? :)bulb :)bulb

But what's the burn rate on the stuff?

30% more than gas.

When I first switched to E85 I had a Haltech E6K ECU and they base their fueling on injector pulse width.
I added 30% across the board to the gas maps I had and watched the O2 sensor from there to tune from.
I cut it back some to get in the proper A/F range for E85 and It ended up being 28% more fuel than gas for the same 20# boost I ran with that setup.

Switching from gas to E85 took about 1/2 hour and cost me nothing.
Try that with a carb or a mechanical dribbler. :stir:

I figure I get 2 1/2 - 3 mpg at 35 -40 mph.
I bet most aren't getting that on gas now.

So Mark, you have perfect A/F and impecable timing, but where is your WOW factor. You have to remember some cave type people are still stuck in the "stone with a hole in it" leaker, drippler setup, and need to over compensate for size complex issues they have. Sometimes nothing less than a an over sized big and ugly hat can appease them. Common sense and performance are secondary to the oooooh, ahhhhhh, woooooow. Doesn't matter if its fast or not, just so long as it looks the part.:)sphss
Milage, you don't need no stink'n milage when the boat is only on the water once in 2 years.:wink2:

Or more. 30% is the difference between gasoline and E85 in a E85 vehicle or maybe a street deal. Its the starting point for jetting. But most will find that maxiumum torque will higher than that.

Jon, what do you run with 13 to 1 that you can buy on the docks?



I'd have no hesitation running the av gas at Fishers. I don't even think I'd have to run it at less than 30*

Now I'd watch the size of the Nos shot, but other than that I'd not worry about it. I think the dynamic compression ratio of the 565 is pretty low ( for what that's worth)

main floor, row "A" for $9.00. Now thats funny.

Stone is the "hi tech" setup. The early stuff required you to hunt up a puka shell with the right sized hole in it. Maxi's engine builder can remember when you used wood with a hole burned thru with a hot poker. The techn ology hasn't changed a bit. Only the materials used have. The metering accuracy is the same as it was when the wheel was invented. Some where between it runs, and its flooded.

So now your over here talking shit ehh???:)coffee
Just remeber Bob that stone with a hole in it was good enough to have you run all the way across the pits in bako to see if we were cheating...:D And then of course there is always the Mink, 2 US-1 back to back championships, and an enduro title... I think we even broke the speed record in the 85 mph nostalgia class a few times. All this with a wood canoe, a cave man floor sweeper & a mummy driver!:shock: Please continue!:indifferent0001:

yeah yeah. What have you done lately. Thats old news. Thats was back when rocks with holes drilled in them were "hi tech" and your driver was only ancient then, not fossilized.
Cheating? :hmmm: think the jury is still out on that one:hmmm:
You got out of the game when you saw some real comptetion bearing down on you.
Hows things been working for you in the enduro since that miracle on the Parker strip.
