Trust me, you cant ADD 20 degrees of timing and dont get headlift, atleast not on a 3/s turbo.

I just happened to check my oil the other day since I'm starting to bring this thing out more for summer, and it smelled ALOT like E85!

I was tweaking with it on the dyon earlier this week, making decent power, but had random unexplainable knock. Pulled a little timing, and thought nothing of it, it was still there so I figured it was the "phantom". Durring the second pass the oil press fell back to 50psi, and then ~15psi at idle after that.....and inevatibly...clank clank clank...

It's not really the E85's fault, it's mine. But E85 had a harder time starting the car, which initially caused the fuel in the oil, and ethanol is a little more corosive on the oil than regual gas would be.... But oh well....

I'm just going to throw in a $100 SL high compression motor for now, and see how long it lasts!

yesa hard start when cold is a downfall to ethanol. this is why most stations will go to an E70- blend in the winter.



as for the parts that came out of that tahoe.....ive pulled fuel pumps out of vehicles that looked much worse than the 1 he used for the gasoline example that were run on gas only.


for the record i agree with everything thats been posted lately and find it funny that i said pretty much everything about 15 pages ago.


meth is a crutch for an improperly designed fuel system/engine control. period.

The test vehicle can from an owner of an ethanol plan. What nobody is going to scream biased propaganda on this one?

You are really missing the bigger picture here. This engine did not have larger injectors for E85 nor did it have a fuel map for E85. It was setup to run on gas
and he just put E85 in it and ran it. And it worked quite well for him.
Lets take the reverse picture and assume the engine was setup and tuned
to run only on E85. And then he just went ahead and put gas in it and ran it that way without changing anything. Could he be saying the same thing?

Other than the cold start problem I think it is great stuff.
And for someone like me that only runs the car during the summer that is not
a negative at all.

P.S.
A buisness idea for you meth dealers to make some cash from E85.
Design an Ether starting helper for the engine for the winter time.
Something with a replaceable Ether can. That shoots in some Ether just for
winter starts. It could be run by a push button device that you could mount anywhere. Just give it a shot and instant cold start. You can then carry a spare can with you to reload when your current can goes empty.
Sell the kit with 2 cans in it to get the idea accross to always have a spare
with you.

Perhaps a high compression engine will start better in the winter.
If not you could try ether as a starting helper.
Did you use E70 winter blend during your hard starting problem?

In the last month I did notice a slighly lower oil pressure, just under 25psi as opposed to right at 25. Because it's been hotter I thought nothing of it. In hind sight, I'm looking at that as bearing wear due to the E85 in the oil, deteriorating it. This caused a "phantom" knock, which was actually my rod bearing bearly acting up. Then since I beat the piss outa it on the dyno, and even more so at the track, it matured into full grown rod knock.

So, UPP-Do you think doing some preventative work and adding an engine heater would help to minimize cylinder wall washing? Granted the heater may have to be on for a while before you tried to crank it. I'm just trying to think of a way to help get this project a little more off the ground.

I'd like to see (if there are any) awhp #s with E85 on 3/S.

I don't have any dyno numbers just track numbers.

11.65 @ 122 mph at 20 psi and 3900 lbs race weight on E85.

Stealth 316 - Formulas for 1/4 mile ET & mph vs. hp & wgt

Looks like around 550 bhp.

Is that wheel hp?

No, crank. Not sure how accurate it is but I bet it's ballpark.
