GZ Motorsports introduces new LSX Vacuum Pump Kit
(GZ Motorsports Press Release 6/13/2007)
GZ Motorsports, manufacturer of quality affordable racing vacuum pump kits, alternator kits and accessories, introduces their newest bolt on complete racing vacuum pump kit. This time it’s for the popular LS1-LS7 GM engine and specifically designed to fit perfectly in Pontiac and Camaro’s with LS engines. The LS engine is well known for a lot of blow by and resultant contamination of the intake charge with oil forced past the rings into the combustion chamber. This kit eliminates that and allows the rings to seal more effectively, thus adding horse power as well as eliminating unsightly oil leaks.
The new LS Pontiac and Camaro Kit uses the popular GZMS Sportsman vacuum pump (VP101A) which is bolted to the head on the passenger side with a custom stud bolt and set of spacers. A custom designed brace bracket attached to the vacuum pump and the head. The stock tensioner pulley is replaced by a custom designed billet aluminum, slightly larger, 6 rib serpentine with a 14 tooth Gilmer pulley combined to drive the pump. The pump is driven by a 46 tooth Gilmer pulley, which results in a perfect pump speed of 63% engine speed. The inlet from the pump is attached to a custom designed billet replacement oil fill cap, which also holds the vacuum control valve that comes with the kit. The outlet of the pump goes to a custom designed double baffled aluminum breather tank. #10 Stainless braided hose and #10 fittings are supplied with the kit for an even more simple installation. The provided Gilmer belt is the correct length and varies between tight and loose depending on engine temperature. The installed kit makes in excess of 15 or so inches of vacuum without the vacuum control valve, which can be adjusted lower to suit the owner and engine builder’s desires. Applications with Turbo chargers or blowers may benefit from a smaller vacuum pump pulley or the use of the GZMS Pro vacuum pump (VP103) .
