Collection: Go Fast Bits

Blow-Off Valves & Boost Control Since the Late 1990s.
Go Fast Bits
Founded in the late 1990s in Sydney, Australia by engineer John Adrian — who started out chasing more performance from his own Subaru WRX — Go Fast Bits (Accurate Repetition Pty Ltd) designs and manufactures forced-induction hardware to an ISO 9001 quality system. GFB engineered the world's first dual-port blow-off valve, the Hybrid, which won a 2017 SEMA Global Media Award, and grew that technology into the Respons TMS and the electronically adjustable Deceptor Pro. Built around a philosophy of Performance Without Compromise, its valves, boost controllers and wastegates are engineered to bolt onto specific vehicles rather than rely on universal fitment.
