Furthermore, Walkinshaw's 122 Supercharger also boosts torque from 550Nm to an impressive 715Nm (529-lbs /ft). No performance figures have been announced, but let's just tell you that the standard 431HP VRX8 with an automatic gearbox accelerates from 0 to 60 mph (96 km/h) in just 4.9 seconds...
For the record, Vauxhall did not only bolt-on a blower to the LS3 V8. The engineered package also includes a large capacity intercooler, high-flow fuel injectors, a separate cold air intake and Walkinshaw-developed ECU map, while the standard manual gearbox is upgraded with a high-torque capacity clutch.
Buyers also have the option of adding a new Bi-Modal Exhaust that raises power by up to 10-horsepower and allows drivers to select one of two noise settings: 'Street', with an upper limit of 92dbA, or 'Optimum', which releases the LS3 V8's full 102dbA. The two-and-a-half inch diameter system is manufactured from stainless steel with unique chrome tail-pipe finishers and costs £1600.
Other modifications concern the new six-pot front and four-pot rear brake calipers stiffer, height-adjustable springs and Walkinshaw-developed coil-over dampers that have 15 separate valve settings with independent corner adjustment for the owner's preferred setup.
On the outside, the Bathurst S is identifiable by a distinctive graphic pack, front fog light covers and 'Bathurst' badges while inside a console-mounted badge showing the car's build number complements the 'Walkinshaw Performance' tread plates found inside each door opening.
The Vauxhall VXR8 Bathurst S will be produced in a limited number of units with prices in the U.K. set at £44,995 which comes to $66,520 U.S, $99,520 AUS and €51,300 with today's exchange rates.
