Any issues running alcohol and e85?

Just that it goes rich fast and you'll want an aftermarket Ecu to control as much as possible, that includes turning on the pump.

I have my single pre turbo on the car (turbo was maxed) but even that went pig rich and would've needed a big VE tweak to lean out.

I figured as much Thanks

Not necessary. The fuel itself provides the cooling the injection of an additional fluid would provide. It's superior to water injection by far, and alky injection just creates a rich condition that's poorly controlled. E85 is alcohol. You have six alky injectors. A seventh is just going to create complications.

Water/alky injection is a hack. They're "solutions" to a system with insufficient thermal management. Running alcohol itself as the fuel does it all for you. It doesn't need more help.

I made the switch to e85 back in 2006, at that time the cars still had alky on them and I had it turned on at a low setting. After a while I removed it just to de-clutter the cars and get rid of it. The pumps were only gonna do one thing anyways. Quit working.

With E85 you can make enough power & pressure to push the heads right off a 109 and never be anywhere even remotely close to detonation. Lotsa fuel, lotsa boost, and low timing will get it done and she’ll stay together just fine. Adding methanol doesn’t really help anything when there’s no detonation in the way.

No issues whatsoever.
Colder denser air creates the opportunity to make more power.
E85 does not cool the air charge
Running alky through the up pipe does.
Nozzle size and adjusting the curve will yield gains.
But the time has to be put in.

 

[Mr.Spool]

All one has to do is look at intake charge temps and you will quickly realize how you intercooler is doing.

ya every square inch of air above the intake valve is very hot and taking up space my nice methanol cooled air is occupying today.

or not doing

Thanks guys

I'm not sure you mean what you wrote.

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.

I'm guessing you meant E85 doesn't cool the charge before the injector, which is true, but also irrelevant. Whether you inject the alcohol in the up-pipe or the intake runner doesn't matter. The temperature of the charge at the valve is where it counts. Whether you drop the temp in the up-pipe or in the intake runner makes no difference.

It absolutely does matter and does make a difference.
There are substaintial gains there depending on how much is injected spraying alky in the uppipe on top of e85.

Its very relevant

A seventh is just going to create complications.

Its going to create more power in the right hands.
Anything can have complications.
Me and many others have seen the power increases by adding alky before the manifold.
Looking at the air temp/pressure data at various points in the turbo system shows the behavior.
We had more injector duty cycle we could have given it and did try that but in the end more horsepower per lb of boost was achieved with alky injection on top of e85 not just running e85 through the injector.

My temp in the top of the doghouse is 174 No ALKY with E85
My temp in the top of the doghouse with ALKY is 88 logging with holley HP
I was having a problem with the system , good reason to be logging Did I hurt it? No
Some people will say that e85 was a good reason to ditch ALKY and its hardware and headache, as for me im sticking with ALKY

 

[Mr.Spool]

Im gonna throw the cheatsheet out there
Intercooler data is important as is piping size
And the big one=length of piping.
The further away the intercooler is the more time it has to cool the air charge.
Alky will also contribute to the reduction of air temps.

 

[THensley]

yes my cooler is a old 15 row ACUFAB SLC there are better coolers. so I defiantly need a ALKY assist.
But I believe every one would benefit with the use of ALKY

This right here ^^ . Why would you want to complicate your fuel system AND tuning ?? How many monitor their alky pressure or even check pump pressure with a tester ? Just because the motor bogs down when you hit the test button doesn't mean the pump is producing enough pressure overcome boost pressure plus still spray enough alky . On E85 the fuel itself isn't the limiting factor in making power . What are limiting factors in making power on E85 ? The Fuel Supply , (having enough pump , bigger lines & bigger injectors) . The rest is no different than Gas , the Tune , pulling plugs immediately after a WOT blast , be it on a dyno or down the street , seeing what the motor needs .

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?

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
