im looking for any one running FI, or NA even that has hurt a motor that was on e85 as I cant seem to find any.

also, what got hurt?

 

Any motor that's not tuned properly can be hurt, even running e85 or race fuel.

 

But....E85 tends to be a bit more forgiving than pump gas, many would even say its more forgiving that race gas in certain applications...

 

14lbs of boost, stock bottom end LS1, Ethanol, Broke #5 ringland...........

Logs never showed Knock

 

LOL you were asking for trouble on that one. Cant blame e85 for that.

 

Would never imagine blaming E85 for that, lol. He just asked if anyone running E85 hurt their motor, lol. Didnt ask what caused it

 

You clever guy haha

 

Cant be too clever, or i wouldnt have hurt my motor

 

Was the sensitivity of the knock sensors turned down at all? Decent boost on a stock motor lol

 

Nope, lol

 

How much power were you making?

Weak pistons can break without detonation, best fuel in the world can't help that

 

we know that, and we never blamed anything but MY OWN greed. LOL.

No clue on power, never dyno'd or tracked it. Just fun street car.

Again, we know it was too much for her. We were having fun. lol

 

Piston ringlands can only handle so much pressure, which is torque, before they crack. Supposedly that limit is in the range of 500-550 ft/lbs of torque before they let go. I'm hoping to keep my car alive for a year or so till I can do a new shortblock.

 

it also would depend on the "load" as well... a lighter car with less street driving and 1/8th mile hits would probably live longer than a big car making hwy runs or 1/4 hits... just what ive noticed from browsing

 

I have seen real bad cylinder walls of e85

 

I would agree with this, as i know a couple Fox swaps that ran equal setup with the same boost and lived a hell of a lot longer then i did, my damn 4000lb car didnt help, LOL!

Thats why im buying an RX7 next week sub 3000lb car

 

I don't see how in the world E85 would cause that. Cylinder walls where fine in my motor after 100-130 mid to low 8 second passes on E85 on this past motor and the motor before that went high to mid 8's and the same amount of passes and came apart looking brand new.

 

interesting i asked this yesterday as i windowed my motor on e85 last night looking for a 5 second pass after running a 6.04 and a 6.07

apparently e85 does not save your motor when you forget to put fuel in the tank and run it lean on 15psi and 7500 rpms. lol

 

71 chevy ..... Hate to hear that but congrats on the times.... Get another 3oo dollar motor and go for it

 

awesome man... i followed all of your builds... hope to be done with my turbo setup soon on my 240
