Paxton AutomotiveA stalwart in the automotive supercharger industry, Paxton Automotive needs no introduction for many enthusiasts. Paxton blowers have been available for automotive applications since the '40s. During the mid-'50s its VS-57 with patented ball drive proved popular enough that it was listed as a factory option on some Studebakers and Ford vehicles. A derivative, the VR-57, incorporated a variable rate planetary drive ratio to increase the step up and hence promote increased power via greater boost at higher rpm. This blower was installed in the legendary '57 F Bird and dominated NASCAR racing to such an extent that year that blowers were outlawed in the sport. In the '60s Paxton worked with Shelby American to develop a line of superchargers designed for the small-block 289/302 V-8. These blowers, dubbed the SN60, which featured a stronger internal drive mechanism than the VR-57, became factory options on Shelby GT350 Mustangs from 1966 to 1969. Smog regulations and fuel economy concerns in the early '70s sounded the death knell for supercharger development (albeit temporarily). By the mid '80s, with the auto industry embracing electronic fuel injection and coping with emissions and fuel economy targets, the supercharger started making a comeback. Paxton reintroduced the SN60 for the 302 V-8, this time on the Fox 5.0L Mustang. It was later joined by improved versions of the ball-drive unit, designed for higher boost-the SN89, the SN92, and finally, the SN93. As enthusiasts started craving more power, the ball-drive mechanism in these blowers proved to be somewhat fragile, so in 1995, Paxton launched the first of its NOVI direct-driven superchargers-the NOVI 2000. This featured helical gears and a 3.50:1 step up. It was designed to withstand up to 1,000 hp and 20 pounds of boost, which was almost unheard of at the time. Since then Paxton has introduced further versions of the NOVI, including the 200R and RR race-oriented blowers as well as the milder NOVI 1000 and 1200 series. All are aimed at the street crowd, which wanted a dose of extra horsepower. Unlike some of its rivals, Paxton currently offers supercharger kits for fuel-injected and carbureted engines. Take note, vintage Mustang and Ford owners.
Current applications for Paxton superchargers include the following:
