Description

Upgrade your vehicle’s performance effortlessly with the GFB lightweight under-drive pulley kit. Crafted from premium 6061-T6 aluminum billet using state-of-the-art Multi-Axis CNC machines, these pulleys are significantly lighter than their factory steel counterparts, boasting an average weight reduction of around 2kg, with the impressive GFB 300ZX pulley saving over 7kg. This substantial weight reduction minimizes the rotating inertia of the belt train, enabling your engine to accelerate faster, especially noticeable in the lower RPM range before the turbo spools up. The under-driving feature of these pulleys further enhances performance by making the crank pulley smaller, slowing down accessories, and reducing the driven load, particularly at high RPM.

The Atomic Boost Controller takes your performance to new heights. Tested on an MY02 Subaru WRX with minimal modifications, this controller showcases remarkable gains, achieving as much as 18kW (23.4hp) at the wheels. The dyno graph illustrates the Atomic boost curve in green, outperforming the factory curve in blue. With the ability to allow boost to rise significantly earlier than the factory controller, the Atomic ensures better acceleration from a mere 1700RPM earlier in the rev range. Notably, this modification is particularly effective for MY01-02 WRX models, enhancing the driving experience by optimizing the torque curve and power delivery without exceeding the factory peak boost level.

For the SR20DET engine in rear-wheel-drive configuration, the GFB SR20DET lightweight underdrive crank pulley is a game-changer. This improved design not only reduces weight but also features a steel wear sleeve on the oil seal running surface, significantly increasing pulley longevity and preventing potential oil leaks over time. Available in Red and Black, this pulley suits Nissan SR20DE and SR20DET RWD configurations, providing a perfect balance of style and performance. Upgrade your vehicle with the GFB advantage ? experience the power, feel the difference!
