Supercharger whine

have someone weld the silencer ports on your supercharger (which involves removing the supercharger) add a underdrive pulley
 
Ditching the air silencer beneath the air filter box and installing a cold air intake that uses a thin wall metal pipe will increase the whine a lot. Doing same with IC tubes will make it even louder.
 
you want an overdrive pulley, not an underdrive. Ive also found using a custom raised top with a thinner wall also allows the acoustics to come through louder. welding the silencer ports as well. remove any hood insulation.

My fault I said underdrive but meant under sorry
