No A/C, the alternator is sitting where the pump would be. He's running PAS. He is running the standard CPS trigger wheel and single V which the alternator runs off of. He then modified an M43 6tooth crank pulley by machining off the trigger teeth and machining a spacer to sit between the M42 crank pulley and the M43 one running the charger. Can't remember his PAS set up.
