ABSTRACT:
An adjustable turbocharger wastegate controller suitable for after-market installation is disclosed. The invention makes use of the existing factory wastegate mechanism to form a fully adjustable turbine-inlet pressure relief. The factory wastegate valve assembly and the wastegate lever-arm connected to the wastegate shaft are utilized. The invention extends the lever-arm, and applies seating pressure to the valve with a spring assembly using a substantially lower spring-rate than the factory assembly. The spring loading is adjustable over a very wide range, and improved pressure regulation is achieved.
