Dump Valve (polished reenforced recirculating dump valve)

Parts for Saab

All RBM performance Motorsport dump valves are made from billet aluminium and operate with a 10mm larger diameter port than the standard item. This increased area produces both improved throttle response and higher clamping load to maintain boost pressure more reliably.
Our dump valves are all piston operated and suffer none of the failures associated with diaphragm type dump valves.
The Recirculating type dump valves pass the spent air from the turbo-charger back into the intake system with only a small but sporty noise as the air rushes through.
