I am converting to E85 soon and I was kicking around the idea of running E85 through a 7th injector pre turbo instead of methanol with the alky control kit (which I already have) as a solenoid trigger using rail pressure. As I understand, ethanol is much less corrosive and also good at cooling- not as good as methanol but still pretty good- I am decent with electronics and it seems like a relatively simple concept to use the alky control controller to trigger a solenoid under boost and run e 85 straight from the fuel tank using system pressure. It would take some tinkering but I feel like it would be a simpler thing to run- no worries about running out of alky in the tank, easier on the turbo and one less point of failure (alky pump) etc
I'm running a 1985 non intercooled set up and it needs all the help it can get ( I probably will build -or have built-a bad ass pissed off IC engine someday.....some day..)
My main question is whether I would see a comparable cooling affect with E85 vs meth? Am I correct in thinking that it would be easier on the compressor than pre turbo meth? Also wondering if the alky control kit ramps up progressively or is the pump simply on/off?
 
Would this be a safe thing to attempt and would I likely see any real world benefit?
There just my be a very good reason I haven't heard of this so if I'm going to blow myself up please warn me now. I am a diesel Tech not a chemist.

Thanks Chuck. This will work great on my stock apearing LS

what Im not understanding is how the tuning works with atomized fuel in the manifold that cant be metered through the injectors- from what I found on energy density and heat capacity you'd be super rich before you had enough volume to do a lot of cooling and then would the extra charge disperse correctly. Not as simple as it seemed at first. Late night reading binge and now I'm down the rabbit hole. Interesting.
