The 500 series is our ”original” model, available in 5- or 6-stage configurations, designed primarily for most V8 engines over 500 CID. It’s available in multistages and suitable for 4- and 6-cylinder engines where vacuum is desired. This makes it a popular choice for drag racing and offshore marine engines.
Multiple bracket options are available for left- or right-hand BBC mount. The pressure sections range from 20–38 mm (0,787–1,496”), with high-volume gears 30–34 mm available upon request. Scavenge rotors are 43 mm (1,693”) for high vacuum performance. Optional features include a fuel drive mount or an air-oil separator available with straight or 90 degree AN12 fittings.
