ok i just want opinions on the function and where i can find an intercooler small enough to put on the front part of the frame for a tube frame buell. this is a non turbo application, so im just looking for something that looks custom and could quite possibly function a bit. would a small intercooler have a negative effect on a harley motor sucking air through it-remeber non turbo? i want a cone filter for a ramming effect at speed. any opinions would be great. i just cant find an intercooler small enough for the job yet.

Your idea might have merit if you were applying an intercooler (charge-cooler some call it) to an engine that was only run at a constant rpm.

On a motorcycle, I doubt you'd be satisfied with the near glacier speed throttle response you'd get if you tried this in a non-turbo application. You also might blow the whole thing apart if there was ever a backfire that ignited the mixture in the convoluted passages of the intercooler.

It would be interesting if you tried it, though.

Just get a forcewinder. Use the Search. It is a forward facing cone filter that may give a ram air effect. Good power, easy carb tuning and no knee clearance issues. There is a thread on here right now about it and you can search and find much more.

An intercooler's function is to cool air which has been heated above ambient temperature, usually by compression from a turbo or supercharger. In the case of naturally aspirated motor you are not adding heat to the incoming air so you could only benefit if you cooled the air below ambient temperature. I dont' think that an air-to-air intercooler would drop the incoming air far below ambient temperature even at cruising speed. I doubt that the tiny boost in power would make up for the weight or cost of such a system.

"looks custom"

Kinda like those fake kick starters for Softails that custom chrome sells?

While you're at it, see if you can find a real one for my actually turbo'd bike - I DO like your idea of having one that is small and custom-looking, it's just that to put one on a non-turbo bike would have no real purpose other than the first sentence above.

I agree, cooling you intake air with ambient air will serve no purpose except slow throttle response and look different.

Al, take a look at the coolers from the early '90s "Diamondstar" turbo cars - Mitsu Eclipse, Eagle Talon. They were tucked in one front fender and are pretty square. They may still be too big for a bike though. I'm pretty sure you can get one custom made by companies like Spearco. My friend Chris runs www.turbosunleashed.com based in Nevada, check out his site and drop him an email, I'm sure if he can't get you one custom-made, he'll point you to someone who can.

For LimitedX1 - unless you're boosting, I wouldn't bother putting one on. All it's going to do is restrict intake flow, whether you install it pre-carb like an air filter or post-carb with a lot of plumbing. Picture your engine trying to breathe through a honeycomb - no direct path, no air getting through.

Drag racers would use cool cans to keep their fuel cold and add tubs to their intake manifolds to add dry ice.

Now you can go a step further. Weld on a piece of 4" pipe and fill it with liquid propane. As it evaporates it'll cool off the air-intake and the propane will add extra fuel.

Or just make it easy on yourself and add nitrous...
