This car will never see the dragstrip unless it's probably a private track rental and even then it's more than likely to break something in the drivetrain. You know how that goes.

MERRY CHRISTMAS everyone.

Hey Chris, have you worked on the base map and if so does it seem to be ingesting more than usual at idle/cruise than it did before? How does it compare to regular 93 in your experience (fuel consumtionwise)?
BTW are you going to be up north any time this week?

I don't get the whole e85 thing. You have to burn more of it to get the same power, so it pretty much negates any cost savings. Is it that it doesn't detonate as easily?

and it's better then most racefuels that are 4-5 times the price. so it's def worth using compeard to race fuel.

Def worth using compared to race fuels and pretty soon the way gas prices are going up (news reports say it will go up another $.75 by spring) it will be the deffinate alternative! I don't understand why everyone else doesn't jump on the ethanol bandwagon(Mazda, Toyota, Nissan).

E85 is really all about alcohol.
alcohol in it's 3 forms, methanol, ethanol and isopropyl is a completely different animal than gasoline. to the point that it doesn't even mix w gas... so, for example you can't just add some to your gas tank like you can add racegas.
yes, there's less energy per volume in alcohol so you have to run more of it.
the reason you should give it a look is that if you do elect to use it you will gain certain important advantages V gasoline.
gasoline auto ignites at 660 F. that's for race gas and pump.
alcohol autoignites at 858 F.
one of the engine killers in the turbo'd rotary is autoignition and alcohol delivers another 200 degrees of cushion.
alcohol "flashes" atomizes/mixes w the charge air immediately and provides great instantaneous cooling. my upper intake manifold after a 2000-8000 4th gear dyno run is very very cold to the touch. imagine how cold the air is going into the motor. any tuner will tell you that one of the most important metrics as to engine life while on boost is the temperature of the incoming air. w alcohol it is literally frigid.
alcohol has a high octane rating. the problem w coming up w the number (there are many) is that octane is rated at a certain temperature and pressure and it is imposssible to get alcohol up to that temperature due to it's cooling properties.
so even though you have to run a bit more it transforms the dynamic metrics of the air and fuel going thru the motor to the point you can really crank up the boost and the engine is happier (less knock) than at lower boost levels on gas.
i run alcohol (methanol) as an addition to pump gas. see the Auxiliary Injection section. i can also see the merits of running E85.
Alcohol, it's not just what's for dinner.

Nice writeup howard. Im so looking forward to dynoing my T04Z with E85 and 30 psi off boost 
Here E85 is about 40% cheaper then the 99 V-Power fuel i would be using if would run normal gas. Or Race fuel that is 4 times more expensive then the 99 V-Power.
E85 here cost about 5.85 USD pr gallon, and normal 99 V-Power is about 9,09 USD pr gallon. And 102 octan race fuel is about 26,5 USD a gallon. So E85 is the only solution to keep the fuel cheap. Even tho i will use more fuel, and will need to uppgrade the fuel system.
Will be running 6x1680cc injectors.

Performance Veteran...
30PSI from a T04Z ?? Do you have a street port or bridge port as well? I thought the T04Z was pretty much maxxed out by ~28PSI on a ported 13B...
Keep us posted on your results*

How much do you think the additional volume itself is affecting the cooling capability of the fuel?
In layman's terms, the alky nature of the gas is providing better cooling, yes, but how much of that extra cooling is additional volume alone responsible for?
Its really a moot point since whichever way it skins the cat, it sure does skin 'em, but I've thought about this aspect for a while and figured I'd ask now that we have some preliminary results.
