It seem his mesh will offer some protection? Is it enough for a street driven car?

I've done the fender-liner vents along with center vents in front of the hood ... And closed off ALL underbody vents. The temp still climbs in traffic, but once the car gets moving, temps drop quickly to right at 180.

Any problems with damage to the radiators?

Can you show us a picture when you get a chance?

The factory and owners have been doing this to 911s for years .
The 73 rs had a lump cut out of the nose so air going through the front mounted oil cooler had a path under the car .
A few years later on the 935s they cut away the nose and had the path of air going upwards through the hood instead of below .
This was to aim it into the low pressure area above the front of the car .
Pretty much what you're seeing on a gt3 front bumper .
Another school of thought is to let it into the front trunk but exit through the sides into the fender arches so the air can be used to cool the front brakes .
This is pretty much what you are seeing in the pics of Eric's car , but with cutting into the tub .
I can post pictures if you like , but there are plenty out there on the interweb .

Okay...so as long as there mesh there we won't have damage occurring to the rads. I had wondered whether the mesh was enough.

To make things complete I would think the bottom exhaust route would need to be blocked...any pictures as to how these panels can made or bought? Sounds like I will have to make patterns and get hold of a pop rivet gun
