The
Paxton name has been synonymous with automotive performance
for nearly five decades. The company produced the original
production centrifugal supercharger and has made its mark
in every decade as a leader in high performance applications.
Paxton Automotive continues to build on that legacy with the
highest quality supercharger systems available on the market
today.

The legend
of the Paxton superchargers dates back to the inventor Robert
Paxton McCulloch. The original McCulloch supercharger began
production in 1937 for flat head Ford engines. Over 5,000
units were sold in the late 30s. The early 1940s shifted
production to wartime endeavors and supercharger production
was discontinued. The idea for new supercharger capable of
quiet operation, low-end boost and self contained lubrication
emerged in the late 1940s. In 1953, McCulloch released an
all new supercharger to the public.
The new
McCulloch supercharger utilized a planetary ball drive that
offered a 4.4:1 step up ratio from the input shaft to the
impeller. It was lubricated with a mechanical oil pump and
a self contained reservoir of transmission fluid. The supercharger
offered a maximum of 5 psi and significant bottom end power
with the aid of a variable rate input pulley. The V-belt system
allowed the pulley diameter to essentially change based on
engine RPM and power needs. The McCulloch ball drive supercharger
was used on a wide variety of vehicles at the time including
the Kaiser Manhattan, the Packard Panther (five show cars
built), the Studebaker Golden Hawk, the 1957 Packard Clipper
(4,809 produced and rebadged as Studebakers) and the 1958
Packard Hawk (588 produced).
In 1956,
McCulloch set up a special automotive division, Paxton Superchargers
(his middle name), to handle the supercharger division. The
same year the company changed the name of the ball drive supercharger
to the VS-57 and developed a new variable rate supercharger
called the VR-57. The new supercharger incorporated a variable
rate internal planetary drive ratio that could alter the step
up ratio from 3.5:1 to 5.5:1. The variable rate was achieved
by a spring pack that would change the distance between the
ball races based on RPM. The supercharger experienced a one-year
victory in NASCAR causing officials to ban superchargers in
the sport. The supercharger was most notably used as the F-option
on the 1957 Ford Thunderbird (211 produced).

In 1958,
Paxton Superchargers was sold to the Granatelli brothers.
The design of the dated VS-57 was updated to a new model that
could withstand higher RPM and increased boost. The SN-60
required fewer components and eliminated the variable rate
components found in the VS-57 and VR-57.
In 1965, Carroll Shelby contracted with Ford to build a high
performance version of the fastback Mustang, the GT-350. Paxton
Superchargers worked in conjunction with Shelby to design
a limited production run of supercharged GT-350s. The vehicles
were produced in limited quantity from 1966 to 1969. The systems
were also available as a dealer option for Mustangs from 1965
to 1972.
