Made from billet aluminum, 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.


This is a piston design bypass valve that is a direct replacement for the original fitment. This valve gives greater longevity than the diaphragm (OEM) valves but also benefits from its ability to be fitted with different springs when the boost pressure has been increased or the engine has been modified.

To avoid the possibility of a P0101 trouble code, the ECM must be reprogrammed with a tune optimized for atmospheric discharge.




Features:
 

• Crafted from 100% billet aluminum
• Increases throttle response
• Will last longer than original part
• Higher clamping load
• Able to be fitted with different springs to precisely tune the valve to be able to cope with the increased stresses of a modified engine or increased boost pressure
