Just wondering if a fuel cooler could help make any extra power? If so how much. I guess cooler fuel would be denser, causing it to make more power, but flex a lite advertises up to an 80* drop, that seems like a lot to me. Any opinions?
I understand how a cool can or something like that would help, I'm talking about the tube/fin cooler.

 

We use the fuel coolers on our dirt track cars. Fuel coolers and fully insulated lines help out a lot, i would assume that if you did something similar on a truck that it would have the same effects.

 

I honestly cannot see where it would make much of a difference. Cooler fuel would not make as much difference as cooler air would. It won't get much more dense than it already is.

 

i think thats more of a specialty item then what we are in the market for, prolly good for full out race trucks i mean when does your fuel get much over 100* anyways?

 

Also, with fuel injected engines the fuel is constantly cooled by the return lines going back to the tank. (when applicable)

 

Note this: BMW or Mercedez has their fuel lines going through the A/C system somewhere coiled up under the hood.
At least I was told they done this in the past. Not sure if they still do this.
I guess you would definately have to have the A/C on for it to work though.

But if the A/C is on it would mean that its hot outside, thus the vehicle being in the situation when the fuel would need to be cooled.

 

The fuel cooler, or "cool can", can be found in jegs. You won't notice a "seat of the pants feel", but you will notice it on the clock. The logic behind it is that when the air hits the fuel it will remain cooler. Keep in mind were running this on a dirt track race engine in a race car, not daily driven. I dont think there is enough room in our trucks for these, it would have to be a completly different setup probably with a fuel cell.
