Weird sound in high RPM? (H22)
 

hey guys, as the title states, I've got an H22 in my integra and when I get into HIGH rpm's (5900++) vtec is LOUd of course but its accompanied by a loud screeching kind of noise (kind of sounds like a grinding sound). Is it just vibration? the car has AVID motor mounts and avid axles if that may be the cause... There is also no decline in power in that range, it pulls even harder! but I've never owned one of these type of cars and am not sure of some noises I hear lol!

thanks in advance,

Mike.
