Roush Help with My Rattling Series IV Supercharger

[spikestas]

Ok you Guy's - I had my Saleen Series IV Supercharger rebuilt by Saleen( SO they say). Upon recieving it back and putting back on my 2001 Saleen (#434) - it rattled worse than before I sent it to them. They claim that it rattles because it was rebuilt to finer spec's that before. I don't remember it rattling when it bought it (Purchased it new from Saleen and Had Saleen dealer install). It sounds ugly idling and rattles till about 2200 rpm's. Then there's no problem. THe intercooler seem to be working fine. Performance doesn't seem to hurt - still kicks butt. Do I take it back off and send it to someelse (PSE). Know a little about the twin screw operation but? Am worried about summer performance will this thing blow up on me at the track this summer?
Any help would be appreciated!

I may not be able to help except to say that mine makes a similar noise.
I called saleen and they said 1600 for a rebuild. I think i'll stick with the noise, especially since it's not hurting performance.

My blower rattles at idle, 17k miles on it (so I was told), must be somewhat common.
