I'm still debating on running corn or pump w/meth.

I guess what I'm searching for are the problems with running now strictly E85. Wear on pumps, injectors, etc etc.

Setup will be twin bosch 044 pumps with -10 feed to -8 rails and properly sized injectors etc etc. coming from a fuel cell in the trunk.

So in my head corn is superior for two reasons, not spending another 1k on a meth kit. And two having more power while being safer.

Only real down fall that I currently know of, say s not having enough pump locations.

So what do I not know about it that I should know about it???

Someone mentioned to me I should run flex fuel so cute all issues of running just E85, but to me that's out. It's going to be one or the other. No flex fueling.

Any help is much appreciated!!

Thanks-Nik

 

You running this on a n/a setup?

 

bosch 044 pumps don't like E85 and 10an feed is WAY to big.

 

How consistent are the E85 pump stations you'll be using? If your tune is pushing the limits a different blend without enough E content can seriously hurt.

I've been told to get tuned on a lower blend during the summer (tune it rich and don't push the timing) and the computer should compensate for the small changes. In process of switching to E85 for the Subaru, might keep the meth kit running too because injectors are expensive lol

 

This will be on the V when it gets it's procharger.

-10an feed line for 800whp and E85 is what I was told to run. ? I mean I know it's big, and I don't mind if it is over kill.

And I had never heard of those issues with E85. Hmmmm....you thinking it's not worth it and go with pump and meth?

I have no idea if the E85 around here is good or not.

 

Flex fuel just means that you have a sensor that reads the alcohol:gasoline ratio, and adjusts the fuel map accordingly. That's a good thing because e-85 does have it's own issues. Pump e-85 isn't always e-85. Since the alcohol boils off faster, the ratio can change sitting in the tank. Alcohol is also hydrophyllic.

e-85 is nice because it runs cooler than gasoline. On a blown engine in TX, that's a good thing.

It also has a higher octane rating. Which is actually kind of deceptive. The alcohol has a rating of around 120 or so. But the gasoline that they use is the cheapest dregs out of the bottom of the refinery tank; and that can sometimes cause problems. The cheap gas can cause detonation under the first ring land, and you get this.


If you're going to crank up the boost for some track time, buy racing e-100 and add some premium fuel or buy racing e-85.

Pump location is a real issue. You're going to use 20-25% more e-85 than gasoline. How big is your tank?

On a street car that sees occasional track time, you're much better off with pump fuel and a meth kit.

 

Since when? We've been using 044's with E85 on German cars for years without issue. Sure -10 is slightly overkill but it works fine and I'd rather do it once and be done.


I have a -10 feed on my car, its then y'd into -8's feeding the rails with a boost referenced regulated return. Sure it might be overkill but so far I've pushed 26lbs of boost and haven't had a fuel issue. Nice being able to turn it up without worrying about it. Calculators and comparable cars put mine somewhere around 900hp, have no idea if that's accurate or not since I haven't dyno'd it. But I beat the crap out of it and haven't had an issue.

I have a 20 gal tank and get a good bit of range out of it. I can drive an hour and a half to the track, make passes and drive home. I've driven it out of state a few times couple hundred miles either direction without issue. To me that's acceptable MPG for a fuel I can have fun with, aka more boost! Granted I do carry a spare 5 gallon can full of E85 just in case.


Winter blend is actually lower E85 content then summer, usually like 70% winter and 80-85% summer. But really anything over 50% E85 content gets you most of the benefits without any negative.

 

Im still on the fence as to corn or meth

 

Same I have see. Many Bosch 044 without issues on E85.

I say this, if you get a flex fuel setup it's a no brainier to setup for E85 with dual tune or a tune with a range for both fuels. If you aren't then I would say go pump and meth and get a good meth kit. Personally I am going dual tune on my next setup and I am also in the hot *** Texas weather.

 

You're right, maybe thinking backwards...

Higher E content so tune will be a little fat when they change to lower E content. Right?

Summer heat won't allow as crazy of timing and a conservative tune should still hold very close in the winter. Right?

or am I still backwards?
