To David Buschur. What size injectors will I need for 450whp on your dyno on E85 fuel? The turbo that will be used will be a 20glt at 30psi. Will I also need to use you modified Walbro pump? You stated that with E85 you will need larger fuel injectors and a larger fuel pump. I would also like to keep the injector duty cycle at 80 percent at maximum load. Thank for all your testing and research!

I have no first hand experience with the pumps and e85 which is why I'm asking but I am planning on running it in my EVO and would just like to know if anyone can dismiss my worries about them.

So id say 880cc at the least, and yes you would need an upgraded fuel pump.

I hate to turn my own thread into a pile of crap but something that is interesting to me.
I get accused of doing nothing but wanting to sell/promote our parts constantly, which of course I know that isn't my primary purpose behind my posts.
This topic is typical of many others.
I do some testing, do something new whatever and then make a post about our finding. Then magically other poeple jump in and talk about what they did, their results etc. etc. That's fine but it pisses me off that I publically share the information so everyone can gain something from it (whatever the part/test was) and you don't see other shops taking their time to do this.
Just a quick rant.
I go through life pissed off.

Yes E-85 is very good stuff for the price. I was running E-85 for around half of last summer. I did plenty of testing on various seals, gaskets, aluminum, etc... E85 supposedly is pretty corrosive stuff but the only thing I noticed was a TINY amount of oxidation spots here and there. I was also running it with an aluminum fuel cell which looked brand new after many months of using E-85.
I have heard that Walbros dont like E-85 nor are they specifically rated to take it but the A-1000 I had in also wasn't supposed to run E-85 or Methanol but when I spoke with Aeromotive about it they claimed there should be no problems. All Weldon pumps are rated for Methanol.
As for the extra power you see, Alot of it has nothing to do with the Octane rating.. its because of the alcohol part... it keeps things extremely cool. I ran the latter part of the summer with no intercooler and around 23psi with more timing than I could run with pump gas... that is all with no intercooler at all. With an intercooler you should be able to run much higher boost with much more timing with no problems.
Here is some of the info:

anyone who's done any research knows the common FAQ of ethanol, and it really doesn't need to be rehashed in every E-85 thread. He's not selling it, he's just sharing his results.

Based upon my personal experiences you will need 1000cc injectors as a minimum. With my setup I'm seeing IDC as high as 95% running 31 psi peak and tapering to ~25.5 at redline. With DB's dual pump setup you may be able to improve your duty cycles, as I think my fuel pressure is probably dropping off at the top end.

I am thinking my fuel milage will be even lower on summer blend E-85 than it was on the winter blend E-85. Running 80 mph through hilly country I had around a 25% drop in fuel economy (24 mpg down to 18 mpg). I wouldn't be surprised to see 16 mpg highway milage on the summer blend.Keith

First let me answer the question what injectors and pump do you need for 450 whp on our dyno. A standard Walbo on E85 is going to marginal at that power level. The injectors if you intend to keep them at 80% duty cycle will probably need to be 1,000's.
As for V.8MR, you sir are not worthy of my answer. Go somewhere else. I do not want to answer you, help you are sell you parts. I missed your first question and haven't been back here to make a new post lately. Had you simply asked nicely again I'd be glad to answer. Since you want to act like an idiot, I have no desire to answer or do I have an obligation.
The fuel mileage really took a hit Keith, hate to see that. Still for the cost of the fuel and to have the car so smooth with 500+ whp right there all the time, I'd say it is worth it.
