I wish someone would throw 20psi at there set up and do a dyno comparison of 93/meth and E85. I would guess that E85 would make more power but like everyone is saying, it's just not convenient most of the time. I will be running 93/meth on my set up

 

Depends on how much meth... I finished Ahmad's truck a couple weeks ago, and at full tilt the fueling is about 35% methanol. There is no power enrichment in the tune lol. There are some crazy people on this site who run even more...

 

Go over to Lightningrodder forums. Or talk to their tuners, they deal with very high AIT temps from their blowers, more so then us turbo guys, but E85 setups all make more power then the traditional 93/meth setups. I've seen and heard it first hand on Lightning only dyno days here in Charleston.

 

That is pretty funny What size nozzles are you using in his truck?

Yea there is no doubt E85 makes more power. It would just be cool to see a back to back dyno graph of how much power us 93/meth users are leaving on the table at 20psi.

 

im no scientist by any means but i have a friend that is a chemist by profession and he is the one that introduced me to e85 and i wish he was apart of the forum to break it down to you why its better but i cant. one thing im convinced of is how e85 is like adding a safety feature to your engine. while in full boost (18psi at the time, with 20* timing +) i had one of my 2 pumps quit on me , air fuels with through the roof (started at 13afr when pump let go and worked its way up to 17+ afr's) no i didnt lift lol . no damage was done and truck is still on its stock internals ,needless to say im a believer of the stuff . if your meth pump went out while you were in full kill race would your motor be ok or even ok to finish out the race ? obviously meth and 93 work and work well, only thing i would be worried about if i were you is if your ok with the inconvenience of running e85 (limited pumps) and if your ok with the crappier mileage your going to get . on the power side of things ive never ran meth on my truck but going from pump to e85 was a HUGE difference , we were able to go from like 16* to 23/4* of timing and not to mention it burns allot colder then regular fuel so you dont need to spray meth .ive been running e85 since 2009 in the same truck so this is just speaking from personal experience not from a book or web page so i dont know if it helps, obviously what your doing now works but i would like to see if e85 would help you , it would be interesting to see .

 

2 15s and 1 10gph nozzles.

Also, lets keep in mind here that introducing fuel sooner in the intake increases cylinder air charge density, so you can get more air into each cylinder before the intake valve closes. E85 does most of the heat absorbing once it gets into the cylinder. So, adding fuel sooner or later each have their own benefits and help make more power, but they do it in different ways

 

Well , I am running 2 m15 nozzles of straight meth and 93 and was at 20 psi doing some street tuning. I was cautioned by 2 very well repected guys (they are on here) to tone it down or it wouldn't live. Just trying to understand why all that high octane cool meth and 93 can't cope with 20 psi! Thanks for the discussion so far!!!
Please continue!

 

Only reason it wouldn't live is if it has a jackass tune on it.. Now will it make as much power as more nozzles or adding e85...probably not.

 

I run corn solely for the smell.

I have a very tame setup so far, but once I have everything lined up (have my rear end, and more fuel left) I plan to push 20+ psi. People asked me last year at a big event locally why I was running e85 with only 6 psi, they couldn't understand I just wrapped up my install and had plans in the future to turn the wick up. I only have two stations in my town, one about 5 minutes away, the other about 10. There are a few more in surrounding cities.

 

I also don't understand why people say meth injected engines won't live long. Can someone explain how the meth could be harmful? I have seen it hurt roots blower internals but never on a turbo set up.
