Pinning the ATI pulley Anybody have pics of this?How hard is it to do?
I've already got a ATI pulley on the car and it fought the whole way on.Is it possible to run 8lbs without pinning?

Well... a little more than that. 
You either have to have a keyway grooved in your stock harmonic balacer or get the superdamper (which comes with a keyway). If you do the lattter, you need another crank pulley that attaches to the Superdamper (ATI Procharger makes one now that is 8-rib).

I assume by ATI pulley you mean the ATI pulley that bolts to the stock balancer. If you have that you can get a pin kit from ATI (the supercharger company) that drills right from the front, they include them in the C5 kits and the magnuson kits also come with them. No need to remove the balancer, just the fans if you dont have a right angle drill. Takes about 5 minutes to do once you have the crank bolt off.
If you have an ATI superdamper it is already keyed and you need to buy their key kit, it requires you to remove the damper/hub but its still fairly easy once you get the hub off.
I have mine done with the stock damper, I had a pin kit from a C5 procharger kit here at the time so I did it for the heck of it. 8psi on a stock motor should be fine without it but anything over that, and especially a M6 car, I would get it done.

Slowhawk,
I can save you some $ i have the ATI kit cause of the vettes that I have done, its alot easier on an f-body than on a vette. I'll let you borrow it or I can swing down and help, unless you want to buy the kit to keep for future installs.
