Is this typical? After several hours on a hot day it will even get a very high pitched hum. On a cool day, or before warm up, it is quiet.

Yes, from what I've been told, a certain amount of gear rattle is normal and it should go away under load. What I have a problem with is a loud high pitched whine that developed after 4.5 hours of hyway driving on a warm day. The car sat over night and the whine was gone, but returns, though not nearly as loud, in similar conditions. I plan on checking the oil return line Monday, and sending the blower to Paxton for evaluation. I have done several auto-cross events and a hill climb that didn't seem to effect it.

I have had 3, all of them sounded similar to that...the only thing that I would add is there is a very small oil port in the feed line, and if anything blocks that feed line the SC will be oil starved. The only reason I know this is because I starved a nv1200 and it seized up. The guys at Paxton said to never use the Teflon tape on the oil line fittings. They suspected that a small piece got clogged in my port...but could never prove it.

Thanks for the input. We found a kink in the air to air return hose which I'm sure effected cooling over long drives. Since the unit is out I am sending it for evaluation just to be on the safe side. I would also like to thank Evans Tuning, the folks at SoS, and Paxton for support and advise.

I had that exact same metallic rattle sound decided to send my novi 1200 in for a rebuild and we discovered the bearings were worn and so was the back gear case where it holds the bearing. Mine was due to excessive belt tension. I did not trust that metallic sounding rattle.
