Factory Pulley size vs APR STAGE 2 pulley

[Ryan_qttro]

Figured since I had the 2 cars available I would post pics, It was discussed in the thread with RAD69 looking at a used S4 over the wknd, and wasnt sure if it had pulley upgrade or not.
This is Factory Pulley

This is APR's pulley

Sorry its flipped upside down, I've got the picture sitting the correct way in photobucket
Kinda worked out you can see the pullies closer to each other this way.
Anyway enjoy.

Normally you can tell if you put the supercharger/engine cover on, there is an a tad larger than normal gap between the cover and the pulley. I don't have any pictures because my car is at the dealership right now, maybe someone can offer some up.

edit:
My bad if you were looking for actual diameter size, didn't read fully

I measured them both with calipers, OEM was 69.69 APR was 64.64 Awe is supposed to be smaller but haven't seen one to measure it yet.

The only way to know is to measure the pulley diameter and compare to the known tuner pulleys.

The sizes in the table are measured at tips of the belt ribs.

I think the sizes measured here are at the tips of the shoulder.

Doing the shoulder is easier as you don't have to remove the belt.

@OP measure the pulley diameter and get back to us.
