Ok, when driving my mustang after we just replaced the clutch, flywheel, pilot bearing, and throwout bearing, when at high rpms, in N, it will make like a metal spinning on metal noise, kind of a whine, is this a bad throwout bearing or what?

because if its the throwout bearing im gonna be pissed after i spend $600+ for this clutch kit, then the bearing is bad, and i have to rip it all out again...

Thanks for the help SCS!!
