|We put this complete vac. pump kit together using the Star Machine Sportsman Vac. pump.
We made our own billet Pontiac specific bracket that can be mounted on either the pass side or drivers side head along with our own heavy duty one piece billet drive mandrel that accepts all the Star Machine drive pulleys and utilizes the standard Pontiac 4 bolt pulley pattern or the 3 bolt Chevy pattern found on ATI super dampers as well as others. The kit includes the Star Sportsman pump with aluminum 24 tooth pulley, SD mounting bracket with spacers, SD drive mandrel with hardware and 12 tooth drive pulley, gilmer belt, aluminum catch can with breather and hose with required fittings. This is a great kit which we've tested both on the street and strip. We typically see 15-30hp gains running this setup
