shit, I'm actually thinking I remember it being $0.64 for a very short period of time... (like a day or two)

and I"m not that fucking old! (21)

I told myself a couple years ago I was giving up cars and taking up stamp collecting.

I think now is the time to go through with that.

yep, time to sell both the cars and find something efficient.

15mpg in the explorer and premium (granted I can get 20+) in the Tbird....

ack.

I remember....

Thanks

you people all need to do a lot of research before you even think about putting e85 into your cars.
first- if you would google for "e85 blend," you would see that ethanol is about 113 octane and e85 is about 110. or i could save you the time:
http://www.hannity.com/forum/archive/index.php/t-14622.html <~~ find octane on the page
second - have you ever looked at drag cars that burn alcohol? how big are the injectors? 1000-2000cc/min is not uncommon, because alcohol has much less energy than gasoline.
third - kiss all the rubber and aluminum in your fuel system goodbye, because alcohol will eat it over time. it's recommended to not use more than 30% alcohol in normal gasoline engines, but you would need more gasoline (as opposed to less with higher octane gasoline).
fourth - because of it having less energy per unit, mileage would decrease relative to what percentage alcohol is in the system... so the final fuel cost to travel x miles would be almost the same. however, because of all the modifications necessary to run it safely... e85 would cost more with a normal car.
i've tried, it works, but not as well as 92 or 93 octane. don't use it.
and for the rest of you children spouting off about something that you don't know anything about... perhaps you should do a little research before spreading false facts?

me personally, id build a motor/fuel system that would be able to handle e85...also, i think 1000hp with 1000-2000cc of fuel isnt bad...remember, drag cars are designed to eat up fuel and make 1000hp/cyl on average...trust me, ive been researching this idea for months, so im not a total idiot on the subject...

If one were to build a motor to run off of E85 specifically (somewhere in the neighborhood of 13 or 14:1 compression, tuned accordingly with a standalone) you could get some serious HP and not too shabby mileage out of it.

Now, Ive been looking into it just from a fun standpoint. Considering building a high compression(11:1) low boost(7 or 8psi) combo. I think you could have a lot of fun with that. Another bad idea would be to make an overly complicated turbo header with a jake brake type SWING valve to switch between routing the exhaust to the turbo (E85), or just straight to the exhaust (gasoline) and running it on MegaSquirt & Spark Extra with 2 different VE tables and just switch them depending on whats in my tank or if Im at the track or not.

it's not how high of octane you can run, it's how low. you're not going to see performance gains running 93 in a car that runs fine on 87 (or anything worth noticing) - so if it doesn't detonate, use it. too high of octane, I believe it won't burn it fully (It hink that was result), too low of octane will leave your motor in the street.

While this is true, some race fuels are oxygenated and therefore can actually add slight power increases while still preventing detonation.

So what's the highest octane my 4 banger can run? It has the usual aftermarket stuff. Intake, header, exhaust, ignition. No internal work.
