Abstract
A pneumatically controlled altitude compensating boost control for maintaining a constant intake manifold pressure on a turbocharged engine having a wastegate valve for selectively bypassing engine exhaust gas around the turbine. The altitude compensating boost control comprises an altitude compensating bleed valve means which varies the compressor outlet pressure in the control in response to the change in ambient pressure and a wastegate actuator which is responsive to the ambient pressure and the varied compressor outlet pressure.
