Uhh, that belt looks awfull. Wonder what happened....
You don't need larger valves with Stage II cams on S4. Larger valves will slow down the air velocity even more
and you only loose the bottom end torque and won't gain any extra hp.
Nice MAP setup, was that easy to tune and how is the idle? I have been wondering, what's the best place for MAP on stock intake...

The gear walked forward and shredded the belt.
ILL see what the flow bench test GB did say but I understand totally what you are saying and the reduction of velocity is true.
That is not the MAP, that is just an aluminum tube with a temp sensor where the MAF use to be.
I mounted the MAP here, see orange connector

Here it is under the flappy solenoid

I'd be carefully checking everything in the belt circuit to make sure it wasn't additional stress due to another failed component.. are the rollers running true, no pins bent, tensioner all there correctly etc.

Running the aluminium oil pump gear didn't cause your failure. Plenty of 928's running the aluminium gear for over 100k miles without walking off like you experienced. (I removed the original one off my 89 at 152k miles)

If I had installed the steel gear, the torque on the nut "may" not have come loose.
