I will need to let the trapped air out somehere on my front wings/fenders and would like to mount my intercooler in the path. Would it be better to channel the air into a narrower spot farther back the fender or closer to the front as in just a few inches behind the slope of the fender opening. I figure I will need an inner wheel well to channel the air /debris trapped over the wheel out seperately as to not trash the cooler. Any ideas.
Thanks

general rule is smallest air intake you can get away with (smaller=less drag), and a much larger exhaust. If the air behind the cooler is lower press than the air in front it will flow better. So a straight, even tube from a high pressure area to the intercooler, then an expanding tube to a low pressure area after the intercooler.
Have a look at some LMP cars. They all vent the wheel arches, and often the brakes/pods around where I think you want to.
Cheers.

My old 200SX used to vent to the intercooler through the back of the wheel arch with a simple slotted panel. It very quickly got clogged with road crud so some kind of baffle would be a good idea, although you don't want to restrict the airflow too much.

Nothing to do with the thread - but that car is starting to look very nice!

Thanks for the replies. may have found a solution for most of the trapped air between the body and fender/wing.
Insperation via mgtd andbmw 328. Will still have to get air into the intercooler and out but this should help a fair bit.

I will have to round off the top of the fender though.
