Me too. It's going to let me do a two-step process:

1) This coming "down" season (Yeah. I know... we're not done with THIS one yet.), build the engine for gasoline, with ~10.5 static compression.

2) The following down season, build an entirely new fuel system, seperate from the stock one, add an X-Trim and control the whole thing with FAST.

 

What vehicle are you starting with?

I'm looking at doing this with my 96 impala SS and much later with my 91 caprice. I need to find out what parts in the fuel system that I'll need to change...

 

Fred, thanks for that tip

 

Here is some info I've found out.
Fuel AFRst
E85 stoich 9.765
E85 Max power rich 6.975
E85 Max power lean 8.4687

OK, even if it were a 50/50 mix, I would still be very interested. The Octane rating is only half of it. The natural cooling ability of alcohol is very good compared to gasoline. I betcha you could run factory hypereutectic pistons up to 600hp with no problems.

On the fuel system I have decided that the simplest thing is to just put a cell in the trunk and running new lines up front.

I was thinking of this pump with this regulator

I am also considering building a kind of odd intake manifold. Which reminds me... There's a question I need to ask in the advanced forum.

 

I wouldn't. The issue with hypers is their propensity to shatter when stressed. Forged pistons just deform.


I mean sure, that's oversimplified, but that basic point is accurate.

 

Howard Stewart has worked on that pump for a long time. I have held one in my hand and it was going to be tested but the design wouldn't fit the mechanical test stand due to an unforgiving clearance issue. My problem with the thing is that it runs off the cam lobe of course which pumps for a fairly long duration every two engine cycles. As far as I know all fuel pump lobes are the same. Now there isn't a huge stroke there and there is no compounding of ratio as its a straight shaft. How is that going to provide a smooth flow of 200 gph?
I guess I really just want to talk to someone who has actually ran one that had some high volume fuel demand. I'm a skeptic I guess.

 

Well one good thing is that if you do have any questions or problems you can email or talk to the man himself. He has a forum on his site. That's kinda cool.

 

my god thats alot of fuel

 

Anyone have an opinion on what the max DCR you could run on 104, 110, etc would be?

If 9.0:1 is the limit for 93 octane...

A fraction comparison would be:

9.0:1 = 93
10.0:1 = 104
10.6:1 = 110

However, I have a hunch it is way more complicated than that .

E85 has 72 percent of the energy content by volume, of
gasoline.
To compare price, multiply the price of E85 by 1.39
and compare to gasoline.
Others have written that even non-FlexFuel
cars can run 20 30 40 percent E85.

in other fuel news,
the federal requirement that RFG contain uxygen,
is being dropped, effective May 6.
Note, some MTBE could still be used in RFG gas,
after May 6. but I thik it will soon be either,
less or none, rather quickly.

 

The midwest states will just mandate the crap at their level. The masses are too friggin stupid to understand science and would rather believe a line fed to them by a lobby group.

 

That's probably a better question to ask that what I was asking
