All New 2011 Jaguar XKR Special Edition Model
All New 2011 Jaguar XKR Special Edition – Supercharged! Gotta love the exhaust note!! A sixth-generation, twin vortex system supercharger is fitted to the Jaguar XKR’s 510PS engine. It is a compact Roots-type unit, feeding air through twin intercoolers, which in turn are water-cooled by their own discreet cooling circuit. The high helix rotor design improves the supercharger thermodynamic efficiency by more than 20 percent over its predecessor. It also improves noise quality to the point where the unit is virtually inaudible (making supercharger whine a thing of the past). The intercoolers reduce the temperature of the pressurised intake-air and so optimise power and efficiency. Mechanically, the new supercharger and its intercoolers are efficiently packaged in the ‘V’ of the engine to deliver a lower overall engine height in support of pedestrian safety requirements.
