Morning everyone. Finally getting back to work on the rambler. I cut a hole in the rear of my hood to help get some heat out of the engine compartment and fabricated an aluminum bezel to go around it and hold the grille mesh.
I have stainless button heads in it now but thought counter sunk flat heads might look better. I'm also going to fabricate similar trim bezels to go around my exhaust tips that exit through the rear quarters so I'll use the same type screws there. The bezel is going to be painted the same color as the rest of the car, viper red, so the only shiny stuff will be the aluminum mesh and the stainless fasteners. I'm a bit concerned about painting into the countersunk holes for flat heads and having them pop the paint loose when they're tightened.
What do you guys think about flat heads vrs button heads and which looks best?
Just try to visualize the hood and bezel painted the viper red.

Thanks

I like the button heads and would try to carry that over to the front grill hardware if possible.

Good looking vent!

You should be able to find captive washered flat heads that would be easier on the finish.

But I'd go w/button head allen's w/a thin nylon washer under it, loctited.

If you go w/button heads, clean the socket real good and use a bit of clear on them. Even many so-called stainless fasteners will rust some.

Does it need to be removable? If not you could use flush pop rivets, fill, and never see them again.

Only one problem, at speed that's a high pressure area. Air will be forced in instead of out.

I always thought a cowl induction-type opening worked because of a low pressure area created at the base of the windshield. Counter intuitive at any rate.

May be a moot point because of where that vent's located, it may work on a different principal.

I'd like to keep it removable and I kind of like the looks of the stainless fasteners. As for the front grille, the mesh will sit behind the original trim piece so no fasteners are required I did think about the low pressure area but I'm more interested in removing hot air at low speeds and when the car is stopped. I thought about doing two vents in the hood somewhere around the center and just above each turbo but did'nt think I would like the way it would look. There are two input vents in each front fender that I have'nt finished yet that will duct cool air up around the air cleaners and hopefully across the turbos. I'm hoping these will supply cool air to the engine compartment at higher speeds and help force some hot air out. The summers here are brutal and with turbos and a/c this car will need lots of help to stay cool. If it doesn't work out, I have another hood. I do appreciate the input though, its how I learn.
Thanks

Brainfart! again. You're right Low Pressure.
