Who's interested in replacement belly pan ducts?
#16
If the new factory plastic pans actually have ducts for $230, then this would be the way to go, and I'll probably not waste any time on this project. Coming from a background in metal fab, my guess would be that these wouldn't come in at less than $150/pair in a decent quantity. I thought they were no longer available.

When I first bought my GTS I got a replacement pan from Porsche and its been fine ever since.
I have also seen many cars without the pan without ill effects.
I have fitted the aluminium one from 928Int - great and no ill effects without the ducts.
So the ducts direct air to somewhere? MM maybe.
I have seen no conclusive proof that any of the above combinations have a detrimental effect on the car in normal use.
As for protection I would go with the aluminium one.
For a reduction in drag coefficient I would think having one is better than not.
Other thoughts welcome.

Roger-all valid points, it would seem that the greatest asset of the belly pan is the protection aspect, and to your point alumiNIUM (!!) would work best.
The only thought I had here was the thread I referenced where it seems more than a few people were "ductless", and if they were **** like I am, they may want to rehab to original specs. I was having coffee with a friend yesterday and he mentioned the fabricator, and something in my head clicked on this...

Oh.....put me in for a couple of sets.

Ed,
Sorry did not mean to HiJack the thread - coffee has not kicked in yet and my fingers ran away with me.
I would like to have the option of being able to get the ducts and I am sure 928 Int would like to sell their aluminium ones with the ducts.
If they can be had for a reasonable price and emulate the factory I am in for a dozen sets.

FWIW, aerodyn and sand go hand in hand; there is strong updrafting under there. My '85 has a pan and still had considerable sand in the lower regions; I believe it only spent a couple years near a beach, maybe the PO had the pan off, but he didn't do a lot maint, so I doubt it, but the grit was doing its thing on the crank pinch roller.

Just a random thought on plastic vs aluminum pans, plastic might have been used to do very little damage if it got snagged on something, break away easily etc.
I am still curious about where the air goes from the factory ducts.

The airflow is directed at the engine mounts

As 50 lightbulbs go off in the heads of 928'ers everywhere, I'll vocalize it: do the OEM hydraulic mounts fail prematurely due to chronic overheating in the absence of directed airflow? Is there any data (anecdotal or otherwise) to support the hypothesis?
Why couldn't these ducts be made from fiberglass or better yet carbon Fiber? I'll bet I could make one out of fiberglass in less than a day, just make a mold of the interior shape from a metal one, position the tabs for the mount and fiberglass goes on!
