General Electric turbocharger model B-22 was fitted externally to a Pratt & Whitney R1930 14 cylinder twin wasp radial air-cooled engine for the supply of air at an increased pressure to the carburetor intake. This enabled the B-24 Liberator to maintain a maximum 1300HP at takeoff from sea level to 30,000 ft. ceiling and at high altitude.Round metal supercharger with inlet and outlet.General Electric turbo super charger.

Released in August 2004, the VZ series was a minor facelift of the previous VY series that featured a new V6 engine in different tune guises. The powerplants included 175 and 190 kW (235 and 255 hp), 3.6-litre Alloytec V6 engines in place of the older 3.8-litre Ecotec V6. Other changes to the V6 was the loss of the supercharger that was included in the S models The VZ Commodore was available in several model variations, most of which carried over from the VY range, with the exception of the newly introduced SV6, a specification level that replaced the S range. All models in the Commodore range (Executive, Acclaim, Berlina, Calais, SV6, SV8 and SS) were available as sedans. The advanced 3.6-litre Alloytec engines were more powerful, responsive and fuel-efficient than the outgoing Ecotec V6. To achieve 190 kW (255 hp), the Alloytec V6 gains variable valve timing on both inlet and exhaust sides as well as a dual stage intake manifold, while the 175 kW (235 hp) version retains variable valve timing on the inlet side only. Sales of the VZ series failed to match those of the preceding VY in light of rising small car sales, higher fuel prices and growing interest in the whole new replacement, the VE series. Selected models bring advanced active safety features that electronically assist the driver to maintain vehicle control in emergency situations.
