Because you can run a lot more timing and boost, therefore you can make more power.

I am making 466 WHP on a mustang dyno using 93 OCT pump gas, when I also do my E85 tune, I'll expect my horsepower to be 580WHP+, with the only mods being E85 and a tune.

What ^ said. E85 doesn't burn longer to my knowledge. From what I have read is its a cooler burn allowing you to run alot more timing and boost and get away with a lot less chance of detonation.

 

so i've found a few dual pump hangers, one from Full Blown and the other is Buschur Racing. the full blown dual hanger (bottom link) doesn't have a float hanger on it anywhere from what i can see or how does my float and wiring attach to that?

Don't bother with the full blown unit. It has a bunch of issues. One in particular is when you run the car around or below a 1/4 tank of gas, the gas pickup tube is too short and you won't get any fuel.

Stick with the Buschur double pumper. It's a nice unit. Hardest part of the install for me was getting the new fuel line over the side of the fuel tank without kinking. After that it was a piece of cake.

yeah i've changed my fuel pump quite a few times not, it's easy but it's time consuming, and i have yet to find a actual "tool" that opens that damn black notched lid. so everytime i've welted a bracket together to act as a giant vice-grip.

also recently found a 76 gas station that sells trick fuel(101 octane), 114, 119, 130, and 150 octane. i live right next to Pacific Race Ways in kent, wa. but never realized they sold high octane/race fuels else-where besides AT the track, which they charge way to much for.

so i figured i'll get my car tuned with 92 premium pump gas, then on the trick fuel that's 101 octane.
