B&m 420

i just bought an Apache with the same blower if you don't mind what pulleys are you running and how much boost. Mine are underdriven thinking about 8% over and app 10 lbs of boost.

Doubt that you would get 10# on an under driven B&M Blower. Attached is instructions with pulley sizes and boost. Lot depends on compression and engine size.
