thank you. I have not slept and I was even concerned about posting I had the deposit until the car is safely in my barn. its never over until the fat (cooled) differential sings!

Congrats! You will love the car. Keep us posted of it's progress over time!

hmmm...

RP's ingenious antenna theory shot down by 2 owners in short work....any guess as to who the true dickhead is?

As they say...he who smelt it, dealt it...

Hope someone here picked-up this rolling resto B9.

Tim, Whohler bought that car. Its in AZ now. It is one of his restro projects that he refers to.

A bit harsh don't you think?

ahh, shucks, he's a big boy...just a little pin prick to the ego....we all need it now and then, especially when we get out ahead of ourselves (and become a legend in our own mind)....

he is a nationally recognized expert after all...

And your level of expertise makes you the guy with the pin?

no, not at all....never claimed to be an expert...i purposefully try to underplay my hand so as to not get caught with my pants down (so to speak).

Aren't we (mye28.com'ers)or most of us all legends in out own minds......that is what the rest of the Bimmer community would tell everyone else.....

I heard you picked her up yesterday! Are you driving east? Congrats!

i'm sure someone at BAT pointed it out, but the license plate was kinda clever.

Agreed...I like it too...

Hello. Car is safely in CT. Thank you all for the well wishes.

Hey guys, Can someone explain to me what this belt is?

That is an oil pump driven by belt that can circulate the oil through the oil cooler, in order to keep the oil relatively cool during high speed.

The short version is an oil cooled diff, although B7Turbo's answer is much better.

Theoretically it seems like a waste of energy to me but it may have been necessary at the time. I would assume that you could replace it with a more modern LSD now and eliminate it if you so wanted but that's just my speculation. I would also assume its not necessary here in the states where we don't have unrestricted speeds.

More modern LSD? WTF does that mean?

The diff design relies on airflow under the car. The Alpina Airdam hangs too low to allow sufficient airflow, so the fluid is pumped out of the differential through a heat exchanger that sits behind the left rear wheel and uses the airflow generated by the moving tire to cool the fluid.

E12-based cars had these as well.

Haha, I like your elaboration Wkohler, and thanks.

Do you think it would be possible that the oil itself wasn’t as a good quality as latter years or today’s quality? Also, I never saw these oil cooler diff on any models over 1984 and above.

Well does an E39's diff need to be oil cooled? Would there be another way to direct the airflow under the car to the diff so that it doesn't need the oil pump? Does a 400hp E39 M5 have an oil cooled diff? Are newer differentials designed to handle higher temperatures?

That's where I was going with my comment. Although I probably should have said something like 'a more modern differential design.'
