Description
The factory diverter valves are prone to leaking pressure under increased boost when the car has an upgraded ECU flash. As well, these factory Bosch valves will taper boost off with their diaphragm design even at stock boost levels. To help keep the boost pressure constant all the way to redline, upgrading the stock diverter valve to the VR Racing Diverter Valve Kit will improve your cars overall performance. The VR Diverter Valves are sold as a pair to work specifically for your Porsche Turbo model.
These valves are CNC machined 6061 aluminum which have been precision engineered to fit with the stock or aftermarket boost hoses. The internal construction of the valve uses a machined piston with proper o-rings to ensure a smooth motion that is air tight to prevent any boost leaks. The spring has been engineered to hold moderate to aggressive boost increases on your turbo car. We do supply additional springs and washers should you need the piston to be stiffer or softer based on your needs. If needed, the top of the valve unscrews allowing you to re-greased and service the valve. Valves are available in a black finish that features the Vivid Racing logo laser engraved.
Fitment:
Porsche 991 Turbo
