Made from billet aluminium, the Forge Motorsport atmospheric diverter valve dumps the charge-air to atmosphere creating the “Whoosh” sound most commonly associated with rally cars when the throttle is lifted. This increases both quicker throttle response and higher clamping load to maintain boost pressure more reliably.
