Show original supplier description
The Go GFBT9001 Respons TMS is a direct-fit, bolt-on blow-off valve (BOV) designed to provide performance and customizable sound. Its patented adjustable venting bias system allows users to infinitely adjust the ratio of air vented to atmosphere versus recirculated, ranging from completely silent to fully audible. This flexibility helps to prevent common issues like backfiring and stalling often associated with fixed-ratio atmosphere-venting BOVs. Employing GFB's proven TMS Technology, the Respons valve ensures rapid boost recovery upon gearshifts and maintains optimal throttle response. It is engineered to withstand boost pressures exceeding 100psi, ensuring it can handle the demands of most turbocharger systems. The valve is manufactured in Australia and is ISO 9001 certified. The product offers a huge range of direct bolt-on kits for popular vehicles, with additional hose and flange adaptors available for custom fitments. The product page notes that the team has not yet provided specific fitment data, recommending customers get in touch or check back later. It is manufactured in accordance with ISO 9001 standards.
