new belly pan was created by 87 Shark
I bought my car in January and ii did not have the belly pan . I now know how important it is after reading several posts in various forums. I have ordered a new alumnum pan. I know about the ductsto divert air to cool the motor mounts. I'll cross that bridge when the new pan arrives.
My question is that it appears that the car came with 2 belly pans: afront and a rear pan. Is the new pan from 928 motorsports or 928 intl. just the front pan or both pans incorporated into one? If it is just the front pan do they make an al. rear pan?

I suspect it is just the front pan, as it is the one more commonly damaged or lost. If you ask them, you can let us know :)

I guess I should put the pans back on my GT then, huh?

If it's the ~$300-350 version, it's just the front/engine pan. I just got the one from 928 Spec last week. It has holes to allow the engine belly pan to connect to the 'rear' (more like middle) belly pan.

I've been driving around here(home) without the belly pan but have read about the potential hazards of driving long distances without the pan installed. Will have to do without the back one for now. Planned trip to Boston shark party in Sept. is to far to drive without the pan. I will call and ask once the pan is delivered.

928 racer if you don't want it I'm sure I can find a home for it.

I definitely want them, thanks for the offer though :D

They came off because of the oil leak, that seem to come up after I had the dual disk clutch upgrade done... :mad:

The oil leak is resolved now though, had the rear main seal replace, and replaced the oil soaked clutch parts too.

I have been tempted to ugrade to the x-pipe, but going to high performance cats is costly. Mass. has been picky about inspections in the past, but it is getting older....

I just have been too lazy to put them back on, figuring as soon as I do there will be a reason to take them off. My driving is just around town for the most part.

My 87 does not require emission testing due to the age of the car. I'm still working on my must do list . Rmb and high flow cats are on my nice to have list(at the top).

I believe that is where I am now too. Mass. changed to testing via OBDII interface, and since the 928 doesn't have one.... Of course I need to review their visual inspection requirements as well, as I really want to install an SC sooner rather than later too.

Ontario has some strange rules.In larger pop. areas,e-test are mandatory every 2 years along with a visual inspection. If any thing looks out of place you fail. In small pop. areas this does not apply. When we modify we keep the old parts to re-test. Governments can be a real pain!

Sounds like California. I think their emissions vary within the state. I do know there are those who r&r their SC units before/after inspections, but I don't see me doing that!

My feeling about the belly pan is that it is more of an inconvenience than anything. It's supposedly been proven that a 928 will run cooler with it than without out. If there is any truth to that theory then it sure isn't significant enough to be reflected on the gauge. Just my two cents.

I have never seen a belly pan as my 89 never had one when I got it.
Dose it need one?

The only thing that I saw in this thread that caught my eye was that the pan keeps the engine mounts cool.???
I changed my mounts to the 928MS mount so they are not fluid filled, so I wonder if it is a issue?
I also changed the alternator to the 200 amp which dose not use the cooling duct.
I removed my cats and just run straight pipes so maybe this will create less heat in the floor as well?

What do you guys think?

We do not have an inspection here in MI.
I never ran a belly pan as car came w/o one, however I just picked up a used front pan (different one from the 87 up). If looking to re-install one check for all the clips and brackets I see many missing on car I have worked on.

Cooling is not my main concern. Protecting my alternator and ac compressor not to mention the belt from road debris and small animals( lots on the move here) is why I ordered the pan .400$ is cheaper than spoiling a weeks vacation.There is alot of nothing between here and anywhere I want to visit. The car's only been on the road for 2 months and I'm still learning.

One failure seen too often is when the car is lowered and on a big bump impact, the air conditioner will break off the mounting ears from the block. :eek:

I presume you understand an aluminum belly pan won't prevent such an issue. I expect it will do wonders in prevention of cooking small animals on the exhaust though :D

ugh, that is low. Make sure you have your ride height up high.

I surfed a dead deer once on the way out for a weeks trip in my lowered M3. It took a few days for my wife to query about the smell. I was trying to get a hunk of meat off the exhaust in a self serve car wash.

Did you let Carl know that it didn't fit right? Someone with less skill than you might struggle with it. I would also wonder if he has any comments on how low it hangs.

No I didn't, I thought that it was to use the original brackets but I couldn't make it work.

To low for my ride height. I would loose the whole unit trying to get into the garage. Does the alt. sit lower than the front spoiler?

Yeah that is low, it looks to be as low as the Front Brake Air deflectors, and they will rub going over speed bump strips.

How could it be so low when Carl mostly sells racing stuff and track cars are not set up high ?

Also I don't see how my stock pan or any would work w/ that Alt.

My new pan is comming from 928MS. I just want it to stop the local road kill from ending up as a stew on the undercariage. It should also stop any other debris from going where it does not belong.
How did you mount the new alt.?

Where the old Alt. bolts to the engine, 2 flat bars about 4" long bolt to each side and then to the new Alt. making it lower. The hole for the original bottom adjustment bolt is only 5/16 and not the 10 mm like the original so I used the air pump adjustment bolt which is longer but I cut it to length. (I have removed the air pump)
The Alt. swings back and forth on the flat bar bracket, so it swings up but it hits the PS hoses that come out of the pump restricting the swing upwards. I will look into it and mod it more later but needed it to work for my holiday trip.
As you can see in the picture I removed the air dam for city driving, curbs ex-cetera

That install looks unusually low and I wonder why.

We have photos of a correct installation here:
ftp://12.234.229.133/installpdf/alternator%20installation.pdf

...and you can see the alternator is above the oil pan.

(If your browser does not automatically open the alternator installation instructions, go here and click on "High Output Alternator Installation" www.928motorsports.com/install.html

You are right to be concerned about hitting the alternator on the ground. I would not worry about the alternator, but rather the engine. I have written extensively about engine damage from panning the alternator or the air conditioning compressor on the ground. It often breaks the mounting ears off the block and ruins the engine!

A thorough explanation and the cure for this condition is here:

I took some pictures from the front (close up) and it dose not look as bad.

Carl I should apologies because when I look closer it is possible the belt was not on during that first picture.
I posted new pictures

Let me be clear that I am a new 928 owner and am still learning what is normal.

As the pictures show, my install is the same as the 928 MS except for they used a bolt on the belt tensioner and I used the same style as what came off except I used the smaller bolt tensioner with nut that had been used on the air pump bracket.

I had to ad an extra washer for alignment to move the ALT. forward.

The thing that bothered me the most was that the original bottom brackets, sliding adjustment tensioner bolt did not work. If I had not discarded the air pump I would not have had this piece to adapt over.

I could have easily rethreaded the ALT., and due to my newness considered this a design that would fit more then one application, so I used what was on hand.

If I had more time (ILL fix this later) I would also have reshaped the original slotted bracket with an ark so that when tightening, it would follow the natural pivot of the ALT. (can't believe Porsche did not do this)

I am sorry that you were all deceived by the error of my first picture.

When I took new pictures to compare to the 928 MotorSport instructions, I realized that it was not as low as I originally thought.
I think I finished that install around 2 one morning.

I might add that I am extremely happy with the 200 amp Alternator and with very little mechanical knowledge, easy to hang and it is worth the time and money.

That 200 amp alt. is now on my wish list. There is a visible drop on my volt meter when the lights are on as well as the interior fan. I can see when the cooling fans cycle on and off. Minor concern now but will keep an eye on it.
Brad the second set of pictures are much better than the first.
