Car came in for a meth kit so he could run E85 without blending. We based lined the car as it came in. The green line is the base, Blue line is my tune with meth and the Red line is the E85 with meth. Car has a lower pulley, headers, Flex Fuel kit, CAI, and meth system.

Billy, these are fantastic results! I have a few questions if you don't mind about running E85 with meth. How exactly does E85 increase the power when meth is already being used? Since meth raises the octane as it is to run increased timing, what is the E85 doing that the meth can't?

awesome results

The E85 lowers the IATs a ton and the octane is much higher than 93. I can get away with much higher timing with the e85 without kr showing up. PD blowers seem to love the stuff. Plus the meth is sprayed before the rotors the e85 is sprayed right into the combustion chamber. We see most of these pick up at least 30 hp without changing the timing.

FYREANT

All of the above stuff in bold is equally true about meth when run independently already though right? (Lowers IAT, much higher octane to fight detonation, allows much higher timing, etc). Is the primary difference and gain in HP between meth solo vs meth+E85 attributed to it being direct injected instead of atomizing before it gets to the combustion chamber (as in a meth setup)? Or is the gain related to mainly timing?

I run dual meth currently (no E85) and peak at about 20* timing. If I ran E85 on top of my meth would you be adding a couple of degrees?

Sorry for all the questions. Just trying to get a handle on how E85+meth is different than running more meth.

Its more from the timing. I will not add as much timing with a meth and 93 setup because theres no way to be 100% sure that you are getting meth to all the cylinders evenly. With E85 I know for a fact that all the cylinders are getting even fueling.

FYREANT

Thank you, that helps a lot!

Very Welcome sir.

Yea the meth /93 tune up was conservative..

not much difference between meth and E85..

nice power!! I agree I would play it safe as well on the meth..
ive been running 93/e85/meth for a couple of years now

FYREANT

So if I running 20* timing at peak on a dual meth/no E85 setup, would you say my tuner is playing it safe? Or would you say there may be some power left on the table if I switch to like E50 blend with the dual meth? (I realize you may not be able to truly answer that without seeing my tune entirely)

I love running meth and e85. Been using them both for over two years. Best of both worlds.

Billy you guy have got to stop all this crap. I told my self was not going to do nothing to my c7. Was going to keep it 100% stock I shot all of that to ****.

You guys are doing good man really keep it up man. Robert

0Billy@MTI

lol Well I am sorry.... Well not really, lol

0Billy@MTI

Depending on boost level. I stay around 19 on 93/meth

FYREANT

Good to know thank you. If E85 were added assuming an e45/50 blend, how high do you typically take timing for those at peak?

Detoxx03

Just depends on what the motor likes. Every car is different. I’m flex fuel son on 93/meth my car has 14* in it and when I’m on corn it bumps to 16*. We can go higher if needed but it’s still stock bottom end so keeping it together while I still drive the crap out of it.

0Billy@MTI

Lets just say... Many people would say it won't live. I don't really give out my e85 tuning info out.

FYREANT

fair enough

I'm in the process of looking for a tuner for adding E85 to my tune so was just trying to get an idea if it was worth it or if I simply don't have any improvement to gain from adding it.

It’s well worth it
