87... $3.15/gal
89... $3.25
93... $3.35
Race fuel... 100-116 octane, $5-8/gal
E85 (none local yet but lots around and more all the time)... $2.40, 105 octane
I am seriously thinking of doing an E85 turbocar as soon as we get more local infrastructure. Not rotary though, my RX-7 runs in a series that specifies gasoline or Diesel only. E85 is basically Ethanol denatured with gasoline so you can't drink it. (Could you imagine it? Nobody would pay $20 for a liter of booze when they could get it at the pumps for $.50
)But I am thinking "different"... E85 for efficiency... run a small engine with standard compression and stoich AFRs, and the turbo is more of a lost energy reclamation device. E85 for the octane requirements necessary for running under boost under pretty much all conditions except idle.

About that here too, i'm not pimp enough to run that stuff.
A friend is currently rebuilding his motor and is going to run E85 once its back together, so we are going to see what it can do. Should be a full bridge with a T04R and about 25 psi or so. Will be AIing meth if needed, since it is currently installed on the car, but probably won't be needed in the dose that he was running for pump.

For a naturally aspirated car E85 makes no sense. That is unless of course the cost savings makes up for the extra fuel required to go as far. There is also a power penalty. For forced induction use though at least you get a power benefit. Around here with E85 prices right with gasoline prices, it only makes sense for performance reasons when used on in forced inducted engines. You guys that can get it cheap are lucky.

Shoot, we have corn everywhere around here. The prices of bread/wheat is going up because everyone is backing away from farming wheat and moving to corn because of E85.
We also have a billion dollar E85 plant being built down the road from my house.

Naturally aspirated engines can and do benefit from alcohol. Now, naturally aspirated *rotaries* may not benefit, or at least may not benefit as much (it may still help with reflected heat coming off of the rotor face), but to say that alcohol doesn't benefit naturally aspirated cars is ignoring a *looong* history of alcohol powered dragsters and roundy-rounders. As well as some moonshine runners
Most racers use methanol and not ethanol, true. But that is mainly because the BATF doesn't care if you buy methanol by the 55 gallon drum, but ethanol is a major hassle.
We have a T/A dragster... 400ish inch SBC or a "big block" (although a Chevy engineer would be scratching his head if he saw it
, 60psi and lots and lots and lots of alcohol...

True but, im also concernend that the oil will get saturated with ethanol (blow by) that it may cause lubrication issues. Will we need to change oil more often? how much lower is the operating temp? crispeed do you have any info on these questions?
i want to see some people that are using this for a decent amount of time and a decent amount of street miles before i take a chance and possibly blow up my new 20b motor.

??? nothing happens here!
Crispeed... did you try 35-40psi.
Iam still @ 32psi I hope my new engine will be in the enginebay next month, I will try to turn upp to 40psi just cant decide wich turbo to use!!!

let me get this straight. E85 is less energy dense than gas so there is less miles on a gallon E85 than gas (assuming the engine efficiency is the same). BUT E85 is higher octane and better charge cooling properties than gas.
So in a turbo rotary, which uses extra gasoline afrs just to help cool and avoid knock, couldn't you use leaner gas afrs with E85 in moderate boost to augment the lower energy density of E85 without detonating?
so basically, a turbo 13b in vac needs 30% more E85 to get same power but the same 13b in boost needs only 20% more E85 to get same power (because you can run leaner without knock).. right or wrong?
anyways the way i see it, with gas prices now, e85 costs a little less but u have to burn a little more so it comes to about same fuel spending but with the race fuel and AI advantages.. so u still come out on top.
this is of course if u take all the E85 precautions like using premix and extra injector.

Not to mention anouther 044 pump. CJ

I'd rather spend $2.50/Gallon on E85 than $13/Gallon on C16................ and in the end, E85 has the cooling effects alcohol.

going to tune my car soon and we'll see how far i can go with 8500cc of injectors
here v-power 99 octane is $8.82/gallon E85 $5.04/gallon

for your info e85 were +100hp at same psi compared to 95 octane
