Yes Im on the the 15-17 stage 2 crank pulley, 8". MAK inlet as well - full stage two kit with 3.85" 8 rib pulley rev to 7600 which puts the P1 impeller speed at 64748 rpm (65000 max). What pulley size are you running to get 16psi?Stage 2 crank pulley? And the P1X is much nastier than the sc-1. on mine to make 16 @ 58,000 blower rpm with 63K max 21 sounds about right in dense air.
