NOVI-1000 System for 1999 4.6L Ford Mustang GT The modular motor is here to stay, and Paxton Automotive Corporation has introduced supercharging systems for all '96-current 4.6 liter Mustang GT's, featuring the NOVI-1000RR (reverse rotation) gear-driven centrifugal supercharger. The NOVI-1000RR is the same as the original NOVI-1000, except everything is built in a mirror image so the supercharger can be mounted "backwards," with the intake facing towards the front of the engine. This allows the drive pulley to be spun by the engine accessory belt, eliminating the need for an additional supercharger drive system. At a conservative 6-8 psig of boost, this NOVI-1000RR supercharging system produced over 360 horsepower and nearly 390 lb/ft of torque at the motor on 91 octane pump gas with an automatic transmission! The NOVI-1000RR system for the 2001 4.6 liter Mustang GT is the only supercharging system that features beefy 1/2" thick, billet aluminum black anodized mounting brackets, and cast aluminum, rock-honed discharge tube. The 2001 Mustang, with its "returnless" fuel system, receives high-flow injectors to provide the engine with the additional fuel it needs under boost conditions, plus a voucher for a custom-calibrated computer chip to maximize engine performance. Like all Paxton Automotive street supercharging systems, this NOVI-1000RR supercharging system for the 2001 Mustang GT is 50 state legal, OBD II compatible, and comes with all necessary hardware, plumbing and a detailed instruction manual.
