E 85 for my 260?

[ally2dextreme]

Anyone using E 85 for there 260 or 300 drag?

[bigbluechevy454]

Ive always thought this was a good idea but kinda unsure of it also

[Capt.Insane-o]

Good idea if you like rusty internal parts. They can't be parked at the end of the day and left for a couple weeks. IME splashing with race fuel is easier and much less of a pain in the ass.

If your racing with it it's works great, for a recreational boat, bleh.

[ally2dextreme]

Yes you would have to use the boat weekly or pickle it after each trip if it was going to sit awhile between uses.Its alot better than $10 race gas IMO...

[malexie]

I like it alot. And I dont mind flushing the fuel system for 5min at the end of the day.

Kool,are you running stock injectors?

E-85 You can't the engine need near twice the amount of fuel to be not lean side... Yo have to modified all fuel delevery, injectors or jets for a carbs engine. Mod compression ratio, flush after each ride. E-85 is acid and alkalin, attract humidity, stay with gasoline.. For racing application ok but need lot knowlage in engine mod and carburation..

[obrien]

not to mention the engine probably won't live. Just last week while taking some recert classes for mercury, they told us of the problems they were seeing with engines on e15 in durability testing. So I would say stay far away from it.

I like to get on here every couple months and read incorrect E85 statements from the uninformed.

E85 is going to take 28 - 30% more fuel volume than gas. Your fuel pump needs to be up to pumping that much more fuel and the ECU needs to be retuned for E85's A/F ratio. Stoich is 9.7:1 and max power is at 6.9:1 . If that's over your head then don't try it.

I never flushed anything in the fuel system EVER and have run E85 for over 5 years. I leave the fuel in the tanks over the winter and run the same fuel the next spring.

Never had any water contamination problems ever but I don't leave the gas caps open when it's raining either.

E85 will make more power than any gas and will run great at the highest compression you can put to any naturally aspirated engine.
I've put 30# turbo boost to it with no intercooler.
It's cheap and easily available here in Mi.
A no brainer.

Funny but from all the E85 negatives I've read here from the outboard crowd, I never read anything from anyone who ACTUALLY ran the fuel in their engine. It was just all rumors.

[njj502]

And you always forget you don't have oil in your gas.......... Totally with you on the turbo'd 4 stroke stuff, I wouldn't go any other way either.

I think it would be cool to set one up for the hell of it but not on my recreational boat. Too much of a pain flushing when done.

I have been running it for 6 years on 2cyc. I like how it performs with NOS. All your statments are correct, but
on a 2cyc it is a must to flush.

It is a must for performance, you are a racer with race ready engine and you know how to run the engine and you need special lubricant can mix pure methanol or ethanol.. Myself I know all to do to run an engine on E-85(I built heavy modified engines on methanol-nitro). But for a pleasure boater with few knowlage in mechanic, this guy can't... For regular boaters stay away of the E-85

[malexie]

Agree, not for rookies.

The late Steve Heintz and friends supposedly ran E85 in 2.5 260s with great success. The knowledge is out there somewhere.

I ran Methanol Drag sled awhile back, that I would think would be similar to E85 and I have to mostly agree, we couldn't put enough timing or compression(except for trying to roll over a 1220cc triple in -20f with a pull rope) pistons always looked like new, didn't seem like you could run it to lean, would just die if 'ya started to lean on it. BUT, as far as flushing it, without having a wet/dry sump oil system and babbit style bearings, the 2-stroke won't last long.
