The original NOVI-2000 is the centrifugal supercharger that revolutionized the supercharger industry in 1995, and remains Paxton Automotive's most popular supercharger today. Though the NOVI's unique impeller design and compact scroll housing make it capable of producing 27 psi of boost and sustaining 900 horsepower, most Paxton Automotive NOVI-2000 systems are designed to deliver 8 psi of boost. This moderate boost level delivers maximum power and torque, yet is safe for today's engines running on 91 octane or better unleaded pump gasoline. A horsepower gain of up to 50% on most big and small block V8 engines is typical without a loss of fuel economy in cruise situations.
