Boost Recirculation Valve

This a pair of recirculation valves

The 997TT Boost Recirculation Valve is a direct replacement for the OEM unit and features an improved and more efficient design. Our BRV is CNC machined from aircraft grade 6061-T6 aluminum, hard anodized and utilizes military spec Viton™ O-rings. Our CAD designed BRV employs the same operating principal from our 996TT piston diverter valve which has been successfully operating for nearly 8 years.
Combining our successful design principles, stringent theoretical computer and real world testing, the 997TT BRV eliminates issues of boost leaks and diaphragm sticking and deterioration that is consistent with the OEM valve in higher than stock horsepower applications.

This a pair of recirculation valves

DesignTek has developed these OEM Boost Recirculation Valves (BRVs) for the Porsche 997 Turbo VTG turbochargers. Like on the older 996TT, the stock valves use a rubber diaphram which will leak boost on the higher RPM. This part also deteriorates over time leading to boost failure. The new Agency Power BRV uses a piston and spring design like our other popular diverter and blow off valves we have been producing since 2005. This design holds boost pressure all the way to redline and with the VTG design, helps boost come in stronger. The 997 VTG Turbos have the valve mounted directly on to the turbocharger. To add this enhancement on the 997 Turbo, DesignTek had to engineer a product that would be a functional OEM replacement.

Each valve has been CNC machined from 6061 aluminum. The base of the valve was precision engineered down to the ten-thousandth to fit into the stock VTG turbocharger. Inside the base is an aluminum piston that has been 3D machined. This piston is hard anodized and inconjunction with the provided grease and o-rings, provides an air tight seal as the piston moves up and down. Agency Power then had to get the proper spring rate to handle stock boost or high horsepower cars. The top of the valve mates to the base and then 3 allen head bolts fasten it to the turbochargers. The top features a boost nipple for easy connectivity of the stock vacuum line like the OEM unit. The valves are sold in pairs and fit all Porsche 997 Turbo and GT2 vehicles
