E85 vs Alky on H/A

[turbonut85]

So , any of you H/A guys running E85?? I'm looking into doing one or the other. (E85 or Alky) Just wondering what experiences anyone has had with E85 on a H/A. Alot of info on the Alky, but not so much on E85 in a H/A. Not looking for a track only car, mostly street driven with the occasional run to tune and to make me grin.:biggrin: Post up and share your ideas and thoughts.

In round numbers;
For every 10F decrease in temp, you gain about 1 psi equavalent in density.
For each 10F decrease, boost level will drop, and the WG compensates by keeping it constant (Compounded boost increase).
For every lb/boost you gain about 6 HP.

If you have aspirations of running E-85, I would add the alky.
E85 will definitely cool the charge prior to entering the chamber + add octane.
At 20PSI boost (arbitrary number), the intake charge is still around ambient + 200F (Give or take a few degrees ), so, why not knock that temp down a little with the alky, before it starts its path into the intake port.
So, You add alky and turn the boost up +10PSI (example), you get 60HP + net effect of temp reduction.
JMO

It's not uncommon with these HA cars to cruise around on a +90F day and see intake temps of +140F
No actual 100% E85 / conversion experience, but hope this helps.

Anyone else??

well a cool charge is a cool charge. Dyno tests have proven the same car ( intercooled in this case ) will make around 10-12% more power than the same car with 93 + alky. BTW these tests were done on many differnt cars and the outcomes were similar. E-85's cooling ability easily eclipses just alky injection. IMO E-85 is a great application for HA cars.

I'm sure it is posted somewhere, but will E-85 wreck the fuel system/motor?

 

[turbonut85]

From stock setup, what mods are required for the H/A cars to SAFELY run E85 for street use and the occasional track day??

Use E85 in an an alcohol injection system.

Thats a myth that has been formulated due to 2 things. 1. Methanol will eat your fuel system, ethanol is a very distant cousin and by no means has anywhere near the corrosive effects. 2. Old carbed motors will have have problems with E-85 because of the plated parts in the carb itself.


I've been running E-85 in my STOCK fuel system for coming up on 2 years now. No Problems just a hell of alot more power :biggrin:

You will need basically 2 things. Bigger injectors .. rule of thumb is that it will take 30% more fuel for E85 and a macthing chip. Eric at TT does chips, in fact I ran one of his first ones.

In my case I'm running 83# injectors, with an upgraded Kirbans pump from the previous owner and thats it. There is no magic to doing it.

Most street cars would do well with 60s and you will still be able to get into the mid 11s with those even with extrta 30% fuel required by E85.

You could but it will not work near as well as Meth...

Yea, but they don't sell methanol at any gas stations near me. E85 is cheap and easy to find in the Midwest.

You can find meth. pretty easy. You just have to do your homework. I choose to stay away from E85 due to the undocumented effects on the entire fuel system. The best way to get methanol is in a fifty five gallon drum for around $175. The downside is that it is very flamable. Good luck. Brad

Thanks for all the replies guys! This Board is the best tool in the toolbox when it comes to working on the TR! Because of you guys!!

I know the couple guys in our local car group said you want to make sure you tank is clean before running E85 because it works as a cleaner and if there's junk in the tank it will plug up carbs and injectors. The cooling effect from E85 I think would benefit a hot car set up. Might even have to test that theory, who knows what 2009 will bring.

jamie, hows the trans problem going? get it fixed? did u stick with the 200 or did u got with a 350 or 400?

The dirty tank will not apply to all cars. Most of the things that will stop up the injectors will be caught by the fuel filter... period. Yes it does work as a cleaner and it will keep the carbon out of the combustion chamber as well. Most of the dirty tanks I've known in all the years dealing with cars have been from "Garage Queen" cars.

The cooling effect of E-85 easily eclipses alky injection.

BTW: Those are great times for a Hot air, just think if you were running E-85 you'd be in the 10s :tongue:
