For those looking to maximize performance on your P3 Volvo S60/V60, XC60, V70/XC70 or S80, GoFast Bits (GFB) T9358 Diverter Valve Upgrade re-circulation valve upgrade is essential to sustain peak boost levels and extend reliability of your turbocharger.
On the SI6 3.0L 6-cylinder turbocharged engine, Volvo uses a simple, electronic compressor re-circulation valve (eCRV) to recirculate boost pressure when the throttle body plate is closed. The factory eCRV unit are prone to mechanical failures like ripped internal rubber diaphragm or a stuck and seized piston. Lastly, the eCRV is controlled by the Engine Computer Unit (ECU) which results in additional downsides. The ECU is designed to release boost through the eCRV in an “on/off” fashion, like a switch, requiring the turbocharger to spool back up to full boost pressure when it is needed. There is a delay between throttle plate closing and the eCRV releasing pressure. This can result in decreased performance, damaged turbocharger components and pesky check engine lights (CEL). The eCRV is also not considered a “service” item from Volvo, which means if you ever needed to replace it, you’d need to purchase a complete turbocharger assembly; last we checked, they cost over $1000!
GFB solves this problem by replacing the valve parts with anodized billet aluminum housing fitted with a brass piston and machined to perfect tolerances. This results in sharper throttle response, lightning-fast actuation and can hold as much boost as you can throw at it.
