VTA Adapters for the McLaren M838T and M840T Engines
The Weistec VTA (Vent to Atmosphere) Adapter is designed and manufactured as a complete and simple bolt on solution for attaining the "blow-off" sound that many people are fond of on turbocharged vehicles. The 3.8 and 4.0 Twin Turbo engine comes equipped with electronically actuated bypass valves integrated in the turbochargers that recirculate back into the compressor inlet for near silent operation. With the Weistec VTA Adapters, there will be no check engine light as the factory valves are still used, and no tuning or ECU calibration is required.
