The ELEVATE Volvo P3 T6 Dual Port Turbo Compressor Recirculating Valve (CRV or eCRV) is a bit of engineering and manufacturing brilliance that will help keep your turbocharger functioning at its full potential, making maximum boost--and let it be heard. Co-developed and manufactured exclusively for ELEVATE by long time development partner Turbosmart, our Dual Port CRV Blow Off Valve performs! Our robust solenoid and piston design is fast acting and designed to last. Our testing has found that the weak factory solenoid actually gets pushed open (unseated) as boost increases within the turbo compressor housing--actually acting as a bit of a torque limiter by limiting boost pressure. Our stout solenoid keeps the brass valve closed until the computer triggers the valve to open as the throttle is lifted to prevent the turbo from stalling.

The ELEVATE Dual Port design lets your turbo's voice be heard with its blow off valve sound and functionality. Around town with light throttle/low boost driving will not sound much different than stock. The reason being is that the valve piston only cracks open a bit when the throttle is lifted, redirecting all of the boosted air back into the turbo, just as the stock CRV does. However, when you have the throttle down/high boost and snap the throttle closed, the piston in the CRV opens more, directing some air back into the turbo and the remainder being vented to atmosphere through a vent window on the side of the valve, achieving the "whoosh" / "pshhh" sound enthusiasts appreciate. For those that want a stronger design than factory without any change in sound, ELEVATE offers a standard CRV.

Unlike other "upgraded" CRV components that retain the weak link (the factory solenoid), the ELEVATE solution is a complete replacement for the factory CRV including the solenoid and a piston valve assembly in one compact, direct replacement unit. Fits all variants of Volvo 3.0L T6 engines including Polestar models.

What is a Compressor Recirculation Valve (CRV)?
When your turbocharger is generating boost and you release the accelerator (closing the throttle), the boosted air essentially hits a wall (the closed throttle). The pressurized air must be redirected back into the intake of the turbo to prevent turbocharger damage (at the worst) or turbo lag (at the least). A Compressor Reciruculation Valve is activated by an electronic signal from the ECU. The CRV stays closed under boost conditions (directing all boosted air to the engine) or snaps opens when the computer directs it to, redirecting the boosted air within the compressor housing. The factory turbo system utilizes a CRV integrated into the turbocharger compressor housing which essentially closes and opens a port which can be seen in the images.
