How Much Timing/Spark Are You Running With E85?

[nxs450]

I was wondering how much timing guys are running with e85 and say a ported Eaton @ 16lbs?

 

[04SilverSerpent]

I'm conversatively tuned @16 deg..turbo setup. I know some blower cars run 20 or more on E.

I believe a few of the guys here regularly run up to 22 to 23 degress.

Guys he's talking about a ported eaton setup. A lot of guys run 22/23 on pump gas with that, I'm at 21 myself. With your setup and e85 I wouldn't be afraid to go 25/26 area.

I ran 27*'s on the dyno lmao.

You're fine at 23*'s on 93 octane people!

This is also true for those running a 2.76/4lb or 2.9/6lb combo correct?

Ported Eaton @ 16 psi. Run whatever it takes until it stops making power. I would say it will be between 23-24*.

Even if you CAN run 23* on 3, it will still make more on E85 and you benefit from the cooling effect of the fuel.

 

[Posi]

Yes sir. I ran it on mine and many others have with thousands and thousands of miles for many years.

Thanks for the input. I need to check and see where LaSota has mine at. He said I could ad some more with the handheld. I am running ported Eaton with 4lb and 2.76.

how much power did the additional timing add?

whipple 2.9L @ 20 psi 22 degrees on E85

 

[Torrance]

2.6 KB, 22*, 21#, E85

When I swapped from 93 to E85, I picked up 70+ hp in timing alone. Went from 16* to 22*.

 

[Posi]

Just a couple hp. We were on the dyno testing it against some race gas.

yep totally - I can see that. E85 is the shit in preventing detonation with advanced timing and high boost.

26 degrees here. posi port, e-85, 2.9/6lb pulley setup. ran 21-22 degrees on 93 in the past.

26 degrees is pretty steep, how much actually boost and RWHP are making to the wheel?

17.5-18 and it made 552rwhp through stock manifolds.
