Hey RSR
Yes standard short neck
great link and think that must be what I'm hearing. Do you know if it only happens low in the rpm band ? I went out and played with it somemore and when I first crank it I here the knock one time, then I here it when I step on the throttle and maybe when I lift but the muffler is loud. My car has about 40 k miles and has sat a large part of it's life. I will put a stethescope on that area and hope that's the sound.

Ed, are you running the standard "short neck" intercooler configuration? It "may" be the stock recirc valve gaskets. Check here: Changing 930 dump-gaskets, pictures galore
