Drivability blower vs turbos

Gen 3 Hemis have no keyway on the crank to hold the harmonic balancer on. They rely on a press fit.
ProCharger has a pinning kit for use with centrifugal blowers.
If you run a Roots blower, have the crank double keyed before assembly.
Those 6-71 blowers take lots of HP to turn, but they look cool and make instant boost.
The screw type supercharged Gen 3 Hemis are quite impressive!
