What is state of the art in Radiator venting?, Show me you vent holes, water pumpers Options

Hey guys,

As I mentioned in my resto thread, the PO of my V8 car made the vent cutouts in the wheel wells WAY to big, resulting in dangerous cracking. My body guy has just filled the holes back in, so we can start from scratch.


Several of you had mentioned the the current wisdom on these holes is that they can be much smaller and still get the job done. I did a search, but the huge number of possible search terms makes finding much of anything tricky. Soo. . . . if any of you could post some pics of what you have had success with, I would be grateful. I'll update my other thread, but he is nearing completion, and I am so excited, I can't stand it. I want to get the cutouts right, and get some paint on this beotch. (IMG:style_emoticons/default/driving.gif)

Of course the (IMG:style_emoticons/default/driving.gif) part presumes that the freakin' snow will ever be gone, which seems iffy at this point. This is the view of my driveway this minute, and we are due to get a couple more inches tonight.

It seems to me, others have found that exit venting though the hood will only work if you also build a lip to change the air flow, or you end up with a low pressure area due to the normal flow in that spot. Low pressure = low velocity = not great cooling. I've seen at least one really nicely executed example with the lip (Andys), but I prefer the stock sleeper look. The other issue I've always wondered about with a hood vent is whether it doesn't drop hot air right into the cockpit with the top off (think "major low pressure area" with the top off).

I'd love to vent it out the bottom, but I don't think anyone has made this work well. Even going out the wheel wells, with the top on in the fall, if I roll the windows down part way, I suck the hot air exiting into the cabin some. I discovered this a few years back driving to the MWC with the wife. I cracked the window at highway speed to get a little cool air, and the cabin temp actually went up.

I'm just hoping to see what the minimum size is that guys have used successfully.
