Preventing damage to radiators.
Has anyone come up with anything to help protect the radiators on their 997 ?
Home Depot sells rolls of black plastic mesh for gutters the keeps leaves and other debris out and water in that might just do the trick.
Coochas, your post re:" What's in your air intakes ?" inspired this post. All sorts
of things end up in there leaves, pebbles, cigarette butts, sticks, bugs to name a few.

I've been looking for the same thing to attach to the Aerokit front.
I know Cargraphics makes a screen kit, but do not think it fits the Aero. It will fit a std 997/997S front, but you have to remove the front bumper to install them.
I'm still looking....

Deanski and meaker If we catch a projectile and damage a radiator the front spoiler will have to
be removed anyway for R&R radiator. Went through it with my 996. If my memory serves me correctly parts and labor for 1 radiator was in the $700 range. I thinking fiber glassing channels
on the backside of the air intakes that will accept a semi flexible mesh. If the mesh were ever to be
damaged a replacement piece could be installed with out removing the spoiler.

Why doesn't Porsche have a screen installed there? I suspect one (benign) reason is that the air capacity required to flow through the radiator would be significantly reduced by any kind of mesh - if 50% of the surface area is blocked by the mesh material, nearly 50% of the airflow capacity would be similarly reduced. Alternatively, Porsche is just cheap and uncaring.

Take a Colgan Bra for example. It has what appears to be a mesh as fine as a window screen.
I've read that a lot of people like to use them when tracking their cars. It would seem that air flow
would be put to an extreme test in this environment. Anybody out there notice higher oil temps when using a Colgan?

You don't need to know anything about cars to figure out that any decrease in air flow past the radiators will reduce the cooling capacity of the radiator. Since only air movement will aid in reducing coolant temps, INCREASING air flow should be your primary objective when tracking a car. As it is, the 996 and 997 have the minimum requirements for radiator surface size and less than minimum requirement for air flow past the radiators at less than high speeds. Unless the reduction in avalable air movement created by the mesh can be compensated for, you will experience an increase in engine temps, oil temps and a loss in engine perfromance.
One method of compensating for the restricted air flow is to run your engine compartment fan and front fans at full speed during track events.

Running the fans, no matter how hot and how hard you drive, will keep your engine at a minimum of 5% (10F degrees) cooler than if you do not run the fans. All 3 of my fans are fulltime in summer.

^^ I have the flexilite on my Turbo Mazda on all the time as well..
When you are moving the power requirement goes to nothing as the air is basically pushing the fan, not the electric motor..

On the 996, fan air flow is not overcome until you are at about 70 mph. I suspect that it is the same for the 997. This means that the fans will provide more cooling at speeds less than 70 mph.
NOTE: Some tests have shown that the air flow begins to surpass the flow of the fans at around 60 mph, depending on bumper style and 3rd radiator usage.
