Ive seen the cool cans for sale in jegs and summit. If youve never seen what im talking about is a can you fill with water and ice and there is a fuel line coiled up inside it to cool the fuel befor it goes to the engine. They claim you make hp because it cools your fuel. But wouldnt cooler fuel lead to worse atomization and therfore less power? Or will it only increase fuel consumption? Has anyone ever tried out one of these?

 

Good questions. Here are the answers.

It's only for the track, first off. You'll go broke buying ice to keep it filled up on the street.

Yes, it works. It's the poor man's intercooler. Maybe half a tenth or so at the track from using it, it my expereince.

Forget about atomization and fuel ditribution and all that crap that has a lot more to do with idle quality, drivability, part throttle responsiveness and all those other things that straight-line junkies don't give a hoot about. It cools the fuel, which cools the intake air which makes more power. If a few insignificant fuel droplets drop out of suspension becuase of that then so be it. Go up one jet size, problem solved.

Obviously, I'm having a little fun with this post but the dead-serious answer is that it's a good old-school hotrod trick that still works today.

Main downside to it (other than keeping it iced-up) is that you need an adequate fuel pump to keep fuel pressure up there after pushing it though that big coil of fuel line inside the cool can- it's a significant restriction to fuel flow.

 

Cool answer Damon.
