Some factory turbocharged cars have a switch to regulate boost pressure, such as a setting designed for fuel economy and a setting for performance.
42.
The valves limited turbo boost pressure to 4.0 Bar where previously boost was only limited to what the engineers felt the engines could take.
43.
Even higher inlet temperatures ( 246�C or higher ) and boost pressures may be necessary to comply with the emissions standards in the future.
44.
But a programming change in the engine-management system increases the boost pressure under full throttle, creating 240 horsepower instead of the standard Turbo's 222.
45.
The tighter the spring, the more boost that is needed to unseat the ball, and allow the boost pressure to reach the wastegate actuator.
46.
The hydraulic boost pressure to the ailerons was reduced back to as a consequence of the external tanks'weight in the middle of the wingspan.
47.
It displaced per set of three 654 cc chambers ( counting only one chamber per rotor ) and used of boost pressure to produce and.
48.
Due to the lower intake temperatures and denser air charge, more boost pressure and timing advance can be safely added without using higher octane fuel.
49.
Fuel injectors or the fuel pump may not be able to deliver additional fuel needed for higher air flow and power of higher boost pressure.
50.
Opening the wastegate allows the excess energy destined for the turbine to bypass it and pass directly to the exhaust pipe, thus reducing boost pressure.
