Blow Off Valves (BOVs)
FB?s range of Lightweight Under-Drive Pulley Kits are designed to improve acceleration by reduce the rotational mass (inertia) on the crankshaft as well as parasitic loads from the driven accessories.
The pulleys are manufactured from 6061 T6 billet aluminium on the latest precision CNC machines, and typically save up to 2.5kg of weight over the factory pulleys.
Under-driving is achieved through the use of a smaller diameter crank pulley, which reduces the amount of drag from the accessories, particularly at high RPM. Note that GFB take care to ensure that accessory performance is not affected.
GFB Blow Off Ventile are available for e.g. Audi A3/s3, A4, TT, Mazda MX-5, MX6/626, CX7, Mitsubishi Lancer Evo, 3000GT/GTO, Galant VR4, Nissan Silvia, Skyline, GT-R, 300ZX, Skoda Octavia, Seat Ibiza Cupra, Leon, Subaru Impreza WRX, STI, Toyota Celica, Supra, VW Golf GTI, Polo GTI and much other.
