Any issues running alcohol and e85?

[vacuum 6]

My gain knob was on 2 with e85 before i pulled the system out, the car seemed to run better with the knob on 2 with e85 then on 6
but that was probably a tuning issue

makes sense 6 had tuning issues.

Modern ECU's have safeties available for things like AFR and fuel pressure. These safeties watch for AFR running too lean, or fuel pressure not keeping up. When one of these safety monitors activates it shuts off the injectors in order to protect the engine from an impending meltdown. When running an ignition module like a stock ignition or a TR6 you do not have the option of shutting off spark too. In this situation, the alcohol injection system is still going and injecting methanol, so you get a super lean condition (engine at WOT, alky injection on, ignition on, and injectors off).
Try not to let that happen with your setup.

Would be nice to see side by side comparison E85 vs E85 with alky logging air temps, HP gains, etc.

On E85 how much are you turning down the alky?

THensley gave air temp data
With his turbo system.
There is more horsepower per lb of boost when the air is cooler and there is a rule of thumb but there are variables that can affect the power as the motor is an air pump

 

[Mr.Spool]

Why would you want to complicate your fuel system AND tuning ??

Because if you don't have the intercooler to get the temps down enough and the backpressure low enough to move the air with a turbo that has its tongue out (super heating the air) the power won't be what it can or even controllable to reproduce passes at a consistent power level.
This is just one situation where liquid intercoolers,sparaying nitrous in or out of the piping or alky injection with further distances from the intake shine.

Don't you think there should be more definition of how the alky is being used?
By what I read
Your scenario is a car that is spraying alky for fuel displacement.
Say a 15 to 30%
Am I correct?

That is a tuning issue
The alky curve or stage needs to be turned on much later

Alcohol will drag the temperature of the charge going through the valve by down by 15-30 degrees F more than gasoline. Doesn't matter if you inject it into the up-pipe before the throttle or at the injector. You can't say alcohol injection cools the charge and E85 injected by the fuel injectors doesn't. If one is true, they both have to be true. They're the same thing.

Just to add maybe be clearer
E85 and methanol will lower the temps more than 30 degrees more than gasoline.
Both fuels will pull heat out of the area where they are injected into.
