The mechanical supercharger compressor, driven at 5 times the speed of the crankshaft, mainly operates at low engine speeds from idle up to 2,400 revolutions per minute (rpm) to increase low-end torque. At engine speeds just above idle, the belt-driven supercharger provides a boost pressure of 1.75 bar (25.4 psi).
The GM High Feature engine (also known as the HFV6, and including the 3600 LY7 and derivative LP1) is a family of modern DOHC V6 engines produced by General Motors.The series was introduced in 2004 with the Cadillac CTS and the Holden Commodore (VZ).
The rating system for positive-displacement superchargers is usually based on their capacity per revolution. In the case of the Roots blower, the GMC rating pattern is typical. The GMC rating is based on how many two-stroke cylinders - and the size of those cylinders - that it is designed to scavenge , with GMC's model range including 2–71, 3 ...
The sedan's boot capacity was 475 litres (16.8 cu ft), up from the VS series' 443 litres or 15.6 cubic feet, while the wagon's maximum was 2,683 litres (94.7 cu ft). The wagon was bigger still in the respective dimensions listed above by 139 millimetres (5.5 in), 65 millimetres (2.6 in), 123 millimetres (4.8 in) and 150 millimetres (5.9 in). [ 4 ]
The VF Commodore was built on an altered version of the Holden designed GM Zeta platform, first used in the VE Commodore. The VF was an evolution of the VE, with several visual changes. The VF featured new styling at the front and rear, with a more modern, sculpted appearance replacing the VE's simpler design.
Volumetric efficiency (VE) in internal combustion engine engineering is defined as the ratio of the equivalent volume of the fresh air drawn into the cylinder during the intake stroke (if the gases were at the reference condition for density) to the volume of the cylinder itself.

Compared to the VF Commodore, Holden rearranged the specification levels and model nameplates, with only the Calais (and Calais-V) surviving into the ZB series, this name having originated in the VK-series Commodore of 1984 as a luxury focused model. Various price cuts were made and wagon variants are more expensive.
