E46 AC schnitzer supercharged - serpentine belt size
Discussion
Hi all
I'm in desperate need of help
I have an e46 330i with an AC schnitzer supercharger on it
My serpentine belt has disintegrated and I cannot find anywhere what size belt I need
I ordered the stock belt but as it incorporates the supercharger was way too short
Does anybody know what size belt I need to order

Do you still have the old belt or has it been completely destroyed?
The way I see it you have the following options:
-Wait for someone on here to say what size it is.
-Get your old belt and look for part numbers. If it is the original BMW belt it will have a Contitech no. on which you will then be able to source a belt with
-If the old belt is vaguely intact go to a motor factors, even GSF and see what belt sizes they have. IME Motor Parts Direct is better for this kind of stuff
-Try an Alpina approved dealer for the belt. It's worth a shot as you never know
.
The Contitech belt number will look like below:
Where:
6=No. of ribs
PK= The “P” indicates a metric designation, and the “K” indicates the belt is automotive as per SAE J1459
1990=The effective length of the belt in mm. In this case the belt is 1990mm.
The effective length (EL) is basically a measurement derived using the outside circumference of the belt as a reference. As a rule of thumb the EL is:
Outside circumference + 14mm.

In that case your best bet could be (if you know the route of the belt) to measure the run with the tensioner at one extreme & then at the other & find a belt with the same number of ribs as per the info above & if needs be buy one 10mm shorter/longer if you are unsure so that you have a couple of options.
Hi there - having similar difficulties to you - (gradually falling for it more since exchanging the E36 M3 I had for this unsensible family car). However trying to find out thing about part numbers and alike is an utter nightmare.
I believe that the belts come from a US company called Gates Belts - although which belt it is doesn't appear easy having just had a look. If I get home at a reasonable hour from work I will try and take a look at the one on mine and get you some details.
Clearly have to post a bad phone pic to show it off - why not!
Watch this space I work willing I will try and get you the number tonight.

This was going to be another suggestion. It could be a faff but get him in the ballpark
