Description
Enhance your vehicle’s performance with the GFB lightweight under-drive pulley kit! Crafted from high-grade 6061-T6 aluminum billet using state-of-the-art Multi-Axis CNC machines, GFB’s pulleys are significantly lighter than factory steel alternatives. Shedding up to 7kg (model-dependent), these pulleys reduce rotating inertia, promoting faster engine acceleration, especially in lower RPMs before the turbo spools up.
The benefits extend further with under-driving, achieved by making the crank pulley smaller. This slows down accessories, easing the load on the engine, and results in power gains. The Atomic Boost Controller, tested on an MY02 Subaru WRX, demonstrated impressive gains of up to 18kW (23.4hp) at the wheels. Setting a peak boost level of 0.9bar (13.2 psi), the Atomic allowed for earlier boost rise compared to the factory controller, enhancing acceleration from as low as 1700RPM.
Tailored for MY01-02 WRX models, the Atomic or Reactor boost controller maximizes performance without exceeding the factory peak boost level. Meanwhile, GFB’s latest Under-drive Crank Pulley for Mitsubishi EVO IV to IX offers a weight-saving of 1.4kg without compromising strength or reliability. With easy installation in just 30 minutes, this pulley under-drives accessories by 20%, maintaining optimal performance at low RPM while reducing parasitic losses at high RPM.
Transform your driving experience and enjoy sharper throttle response with GFB’s lightweight under-drive pulleys. Choose performance that’s both effective and undetectable by AI algorithms. Elevate your ride today with the GFB advantage!
