I have gone under the nose and made a template of a belly pan of sorts that would integrate with the air dam and extend to the oil pan. How far do factory belly pans go?

I like polishing the inside and painting the underside matte black. The reflection in the engine bay helps illuminate and easy to see leaks of any sort

 

I need a belly pan for my recently aquired 85 if anyone has one. I'm in MA. Thanks.

 

Just measured mine, as its off at the moment. From the mounting hole in the centre to rear edge is ~ 8 1/4"; the outer ends that go under the A?C and alternator are ~10 3/4" back from the mounting hole.

Thanks for the dims, Jpitman2 I will use these as a baseline.

 

These are pics from a '83 belly pan, just back from powder coating.
Let me know if you need different measurements/pics before I put it back on.

Middle

Driver side (alternator side) There is a rounded out area under the alternator.

Passenger side (A/C side) On this side the area under the A/C compressor is less pronounced than under the alternator. That "tear" in the metal at about the 10.75" mark is damage to the pan. Not stock!

 

Perfect! Thank you all.

 

Before I get to the sheet metal,

Here's what I came up with. Comments?

 

Honest question: Does the pre 87 shield really have any practical value? If so what makes it worth the millions people seem to want to pay for it?

My solution for what to do when the temps outside hit 100-115 degrees is to park the Porsches and take the Insight.

 

That looks a lot like my 84 belly pan. If those are available, maybe it could be easily modified for your use.
Good luck,
Dave

 

I am already in the final stage of making my own. I wouldnt know where to start looking for a belly pan for a 84. My design fits somewhat flush with the spoiler and not partial like those I see above.

 

Sounds like the way to go.
Good luck,
Dave

 

Based upon the fact that on each one of the three used pre-87 pans that I have seen had scrapes, dents and/or gouges on the two concave areas that are over the alternator and the A/C compressor and their brackets, I would say that the pans have served some "practical value" in protecting those components! The attached pic is of a pan before I had it painted (pic in post #7 of this thread). If nothing else, the scrapes, dents and, in my case gouge, on the pan would have been to the alternator, A/C compressor and/or their brackets had that pan not been in place.

WALLSTAR -- to that point your mock-up appears to cut around the alternator vent and alternator, so it would not offer any protection there. You may be limited to just a flat piece of sheetmetal, which is why you cut around it, but the factory pans have stamped concave areas over those components, and in fact the pan extends further back over them.

Ok, I was thinking they were part of the air ducting system to keep air from being pulled from the back of the radiator to the front and re-ingested. I did hit a deer last winter with HirschJager, and it was annoying getting the leg meat out of the alternator and breaking the AC belt but things do happen.

Most times when my 928S grounds out it seems to take the hit on those two forward skid plates ahead of the suspension. The fact it does this either means the car is too low or it needs new front shocks, I'm not sure which. I think I'll measure people's ground clearances at Frenzy.
