Hey Guys,
Anyone got a belly pan for my '85 that you want to sell?
Let me know.

Thanx

I might know of one in San Diego. It's off an 83 or 4 engine. I'll find out for you in the morning.

 

Anyone know were I can find a good used belly pan for an 87--&gt;?

TIA

Max

 

I need one as well.
regards,
Sab.

 

Go to Devek.net

They have the Aluminum belly pan...I believe single piece for $229 or $299. Stock belly pans have the tendency to break easily, as to what I heard.

As for cooling, it seems like it will do a lot for air passage through the engine bay. Also you'll have better aerodynamics for your 120MPh+ runs.

Andrew, I’ve seen those nice DEVEK pans and would very much like to have one, but I was hoping to save a few dollars and get a good - fair used one off the net.

Cheers

Max

 

Yes, me too.
That's a lot of cash for what it is - i think anyway.
I was also hoping that someone would have a spare one kicking around for cheap.
Oh well, there is always ebay.

Cheers

LOL, I dont have one either. Seems the first thing that the PO does to our cars.

My friendly mechanic had a few but said the shop he worked out tossed them without him knowing and I agree the price is high for what it seems to do - until I lose a compressor or something

I have only seen one on ebay that I can remember.

 

You Know....

About two years ago I took that thing off when I changed out my radiator. I was in a hurry, and left it in my garage. Leaning against the water heater. Some clown had used wood screws to hold in place, and I needed to go on a trip to Brussels. I resolved to go to Home Depot to get decent replacements when I got back.

Well, about 6 months later, I finally stuffed it up into the attic, where it currently sleeps.

My question: What is the use of this thing? I mean, I understand that it can deflect objects in the road, but I am carefull in my driving and it is so flimsy that I can't imagine it staving off an engine block/
sump puncture. I wondered if the radiator aerodynamics required it, but there was been no change in coolant temperature without it. So what gives?

&lt;--Now that I think of it, I need a cooling hose for my alternator...

?

Normy, I can’t tell you anything about the 85MY 928, the S4- cars are equipped louvered belly pans with cold air ducts, one on each side of the engine that directs fresh air up around the motor mounts and exhaust manifolds (main source of under hood heat). In general it is not only used to smooth out the airflow under the car for high speeds runs, but to controls air flow under the hood.

I think I will just save up and buy one of those Aluminum jobs from DEVEK.

Cheers

Max

P.S. I’m’ still open to a good used one

 

Max, that's an "Unterbodenverkliedung"

[Nicole can tell you if the German is correct-]

It's main purpose is to smooth the flow of undercar air so that maximum speed AND max stability can be achieved.

-Most drivers on the German autobahn do about 140-150 khm....around 86-93 mph. In other countries...such as Belgium, most people do less than 140. In Germany, however, stay out of the left lane, as someone is always going 250 or so. At those speeds, if there is a crest in the roadway, it is easy to run up against the power of the brakes to safely haul you down from speed if the other driver messes up and causes you a distance problem. Word to the wise- if you aren't flying....stay to the right in your lane! the "U" panels help to keep things stable-

Funny, the local trend here in SA is to take it off & throw away. You can walk into any Porsche workshop here and see tons of them stacked in a corner waiting to go to the scrapheap. Undertrays for both front engine & rear engined cars.

I've asked as to why, and been told that it was designed mainly for European conditions but here it's too hot and everything that's rubber under the hood gets cooked. They say if you keep it on you'll be replacing hoses every 30 to 50k.

Or maybe the mechanics are just too lazy to put them back?

 

If you drive through a puddle, and a decent amount of water from it splashes up into your alternator, you'll quicky think of another thing that a missing belly pan would have been useful for. Been there, done that with another car, whose alternator wasn't as low as it is on a 928. The car died instantly and wouldn't restart. That was at around 2:00 AM, and the tow truck showed up at about 3:00 AM. I replaced the missing lower cover on that car the next day.

 

Another function of the bellypan is to control airflow at low speed. If the bellypan is missing, hot air from the radiator will exit straight down while you are stopped or moving very slowly. This hot air is then pulled back thru the radiator, reducing the cooling quite a bit. This can lead to overheating in traffic.

With the pan mounted, the hot air from the radiator is forced to flow over the engine and exhaust, removing the heat from those areas as well as preventing recirculation thru the radiator.

 

Just another real-life story. The PO took the pan off my car for whatever reason. At some point after, he drove over something (a driveway lip, dead possum, ...) I am now the owner of a cracked alternator mount point on the block (PPI missed that one). Whatever he hit left deep scratches over most everything under there, including the alternator itself. My only option is to replace the block in the future.

Hope that helps.
