What car? lol Nope man I have been busy with work and the family stuff. Coaching my twins in t-ball has taken any time I use to have to work on the car. I did take it for a spin a couple weeks ago and the supercharger shaft that holds the pulley on was moving out at least a half inch when you would burp the throttle. So I called off the dyno day, called ATI and sent it back to them to check out. They just did a complete overhaul on it last July. I have been following your crank pulley issues and agree that it helps to pin the crank. I did mine when we installed the supercharger, a buddy made the kit at their machine shop where he works.

I see.....did the blower pulley back out, or is the whole unit just flexing that much?

Also if the crank is keyed, is there a need to pin?

The whole center section/shaft is moving out about 1 in at 2500 rpms. I think on the crank pulley, as long as the factory balancer is keyed or pinned to the crank shft then you will be alright.
