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

 

[Mr.Spool]

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.

please explain "further distances from the intake shine".

 

[Mr.Spool]

please explain "further distances from the intake shine".

Intercoolers require time to cool the air charge
Distance is a strategy that helps

Yes that would be the typical or more common setup (ie a typical alky control kit install)

A setup injecting much much more methanol from an auxiliary system that's not controlled by the engine computer would be in a similar / same situation, rendering the safety shutdown system ineffective when it sees that something has gone wrong.

Using direct coil control instead of an ignition module would allow the ECU to cut spark and provide some protection.

Running a 2nd fuel system for M85 (or whatever fuel) with a second set of injectors (12V switched) would also allow the ECU to maintain control and protect the engine. Plus you'd have the benefit of closed loop AFR control.

If E85 goes away, I'll be engineering "dual fuel" fuel systems for my cars. Like turbo1dr has been doing for years on his malibu.

I have a lot to learn about e85 and spraying ALKY but it can't be that hard to learn as Ill be baby stepping it. I can't spell worthy hoot but I know 185 degree IAT is not going to be the best thing to shove down a 231 throat and hope to make a Hell Cat run home with his teal tucked between his legs.
Today I don't see it as added fuel to my fuel, but cooling, yes it is passing the intake valve as burnable fuel., we can meter it in and measure the results out.
It was not a guessing game with the OE ECU and the new ECU makes it even easer.
Finding the coolest air we can, to be sucked down the engine has be an edge old speed not trick but fact.
I find it odd that so many just hang a big open filter under a hot hood and call it good. Just more work to cool the air charge.
I see a lot of 900 hp capable turbos going high 10's making just 500 mathematical horsepower. Yes there getting the job dune and doing a darn fine job putting the LS and mustang to sham. and when they asked what size turbo I was running and I said 58 mm. most could not believe me and one called me a lier. That was my old combo.I get this new combo sorted out it will send a lot of them home butt hurt.
