Description
Upgrade your vehicle’s performance with the GFB light-weight under-drive pulley kit, a game-changer for enhanced throttle response and increased power! Crafted from top-grade 6061-T6 aluminum billet using cutting-edge Multi-Axis CNC machines, GFB’s pulleys outshine their factory steel counterparts by significantly reducing weight?up to 7kg in the case of the GFB 300ZX pulley. This substantial weight reduction minimizes rotating inertia in the belt train, fostering faster engine acceleration, especially noticeable in the lower RPM range before the turbo engages.
The benefits don’t stop there! GFB’s under-driving technique further optimizes power output by reducing the size of the crank pulley. This slows down accessories and lightens the load, delivering additional power gains, particularly at higher RPM. Rest assured, this modification does not compromise accessory efficiency between idle and 1400RPM, ensuring your battery charging and power steering remain unaffected.
For a turbocharged boost without increasing the pressure, consider the Atomic Boost Controller. Tested on an MY02 Subaru WRX with only a turbo-back exhaust modification, the Atomic outshone the factory controller in spool-up time, exhibiting impressive gains?up to 18kW (23.4hp) at the wheels! Notably, the MY01-02 WRX benefits significantly from this modification due to its conservative factory boost mapping, providing a more lively driving experience without exceeding the factory peak boost level.
The three-pulley Subaru kits, inclusive of crank, alternator, and power steering pulleys, along with required belts, are designed for MY99-00 Subaru Impreza, Forester, Liberty, and Legacy models?both turbo and non-turbo variants. These under-driven sets minimize parasitic losses from accessories, resulting in more power, while their lightweight composition enhances engine response for improved acceleration and a more free-revving feel.
Choose from Blue, Red, and Silver options for a personalized touch. Elevate your driving experience with these meticulously engineered upgrades, providing the best “bang-for-your-buck” modifications available!
