Default Loud grinding noise from D-1SC

Had my D-1SC installed and dyno tuned last week. I put about 150miles on it since the dyno session. Last night i took my wife out for a short sprint in 3rd gear to red line ( 1st,2nd absolutly no traction)and coasted to the upcoming
stop light.When sitting there waiting for the light to turn green i heard this real loud grinding noise,it was my Procharger . I take it home let the car cool down.I check the oil level on the Procharger, it was fine. I then drain the oil on the blower and look at the magnetic drain plug, a little bit of black dust on it but nothing alarming. I put 6oz. of the ATI supplied oil back in the blower start it up and everything seems fine(just the normal Procharger whine).Well take it for another ride and hammer it to redline in third.Now the noise is louder . HAS ANYONE HAD APROBLEM LIKE THIS OR ANY SUGGESTIONS? Please

Thank You

My D-1 started to 'chatter' a lot after I changed to a larger pulley.

I freaked out and did the same thing, it doesnt sound good, but its normal from what I have gathered.
