Did a clutch change on the pathfinder and replaced with the blue print single mass flywheel kit

everything seemed fine but after about 60 miles or so the gearbox has developed a "Light windy sounding howl" which stops when the clutch is depressed

There is more vibrations at low revs which i expected with the sm flywheel conversion...but is the windy howl noise related or could i have damaged the gearbox input shaft or something??? I am not an expert in transmissions so any advice would be appreciated

Who fitted the clutch?

Does sounds like it could be gearbox input shaft bearing, also sounds like the SMF hasn't been balanced. (did you see any holes drilled or weights welded/bolted on the wheel?
Check your gearbox oil level, I would be tempted to drop the oil out of the box and see if you have metal fillings stuck on the bottom plug magnet.
If you do or don't find anything, I'm afraid either way, your taking your gearbox off.
