Blow Off Valve Shortie Plumb Back Mercedes A45 AMG Series 1 2013 - 07.2015 Turbosmart TS-0203-1262 - сервиз

Despite the high boost pressure figures of the AMG four, these vehicles are not fitted with a bypass valve ex works. This is likely because the plastic valves typically found in OEM systems would not be able to handle the A45\'s 26 PSI boost pressure without failing prematurely. As a result, the AMG 45 models suffer from significant supercharger surge. Supercharger surge combined with the high boost pressures of the A45 is a recipe for disaster for the bearings in the turbocharger. This is where Turbosmart\'s Compact Shortie Blow-Off Valve for the A45, CLA45 and GLA45 AMG comes into play. This high-performance valve made from billet aluminium is screwed directly onto the compressor cover of the AMG turbocharger. Both dual port and plumb back variants are available. The owner has the choice between the classic blow-off valve sound of the dual port valve with a 50:50 split between recirculation and venting to atmosphere or the quieter OEM-like operation of the plumb back valve. Both variants drastically reduce the compressor surge that occurs in the standard version of the A45. Thanks to the shortie\'s billet construction and high performance plunger design, where no O-ring is required to seal the body of the blow-off valve against the plunger due to excellent machining tolerances, the valve can easily handle the boost pressure generated by the AMG turbo, ensuring tightness and extreme durability - even if you decide to increase the boost pressure. The VR03 compact shortie kit for the A45, CLA45 and GLA45 AMG includes a boost reference adapter that allows the blow-off valve to respond instantly to the vacuum in the engine, providing better control compared to electronically operated valves. This is possible because the valve can access a pressure reference in the AMG\'s otherwise closed system - without destructive methods such as tapping into the intake manifold. The Boost Reference Adapter provides two pressure ports so that you can connect a second boost pressure controlled accessory, such as a boost pressure gauge.
