+1 I dont understand the point of doing something like this...
I mean I understand running pump and meth, but if you have e85 available why would you risk running it with meth, most people switch from running meth to E85 like I have to keep things safer...

you talk about it as if you have personal experience with it (ironically, you made this thread pertaining to asking help to understand e85 better and if it's worth it), and as if it's a fatal mistake to combine both.
you should probably stop trying to act like an internet tuner so others on here dont have to sift through your bs every time you make a new account after your previous one's get disabled.

You combine ethanol and methanol with a bit of gasoline thrown in and BOOM!
Well, not quite.
Actually, I don't feel there is any real power bonanza to be had in putting a typical methanol injection setup on top of E85. Why?
Well for starters, the stoichiometry of methanol already requires a sizable shot to account for an appreciable percentage of the fuel charge with gasoline, and with 30% more E85 required to reach the same stoichiometry as gasoline, the same methanol shot suddenly became 30% smaller when running on E85.
Secondly, methanol has a much higher effective octane than pump gasoline, but not so much higher than E85. That means even if the methanol shot were increased by 30% to account for the stiochiometry issue, it won't make the same impact with E85 as with pump gasoline.
It's an idea that certainly has crossed the minds of many methanol users, but I don't feel the risk/reward ratio makes much sense.
Just my $0.02.

i can see where someone uses meth inj on top of e85 when they ran out of injector, just to help them either add a "cushion", or to extend it beyond the injectors dc max (obviously not recommended, but people abuse meth injection anyways).
i run 100% water inj w/ e85 and love it, or sometimes like 80%+ water and the rest meth, then toss it in the freezer so that i can get it below freezing temps, then toss that in the injection tank... not necessary to do all that, but it works well according to my IAT logs.

I wish that the ethanol content was controlled better from the pump. I can't use it above 30-35lbs because the %'s are so different from fill-up to fill-up that I knock all over the place. Oh well, MS109 it is.

Yeah, not so much the case down here. I have seen some wild wild fluctuations from week to week during the same season, same batch of fuel, etc. I went one week and tested a sample and it was 75 and the next week with the same batch of E85, same gas station, and same pump, nothing changed except for time, I tested a sample and got 82. This was all during the summer as well if that matters. For the lower boost applications were I can only guess that the tune isn't realizing the full potential of the fuel, it doesn't really matter from what I have gathered, but for the few that run all out 35+psi ***** to the wall, it is no bueno.
