When you rev it up (past 3k rpms) it seems like its making a sound kind of like a supercharger. could it just be my alternator? Its got 600 kms since i put on the gt40s. Havent changed break in oil yet...

Could be anything that moves. Water pump is my guess. Pull the belt and see if it still makes the noise.

I know they changed the cam profile in 89 to help with valve train chatter which resulted in a slightly less cam but I don't know my 88 doesn't make any noises and I'd also check out your alternator. I had one make that noise for a few day of daily driver duty until it started smoking and ****.
