As if the massive V8s from GM were short of power to start with, Aussie-based Walkinshaw Performance has made a new supercharger kit that’ll pump an LS3 V8 up to 566hp (422kW) and 727Nm (537lb-ft) of torque. The kit is also available for the 6.0L L98 V8. Either one will run you somewhere around $14,000 installed - but a lighter wallet will just improve acceleration times, right?

The big Aussie blower features Eaton internals, a custom Walkinshaw Performance inlet manifold and drive system, high-flow fuel injectors and can be outfitted with an air-to-water intercooler as an option.

Utilizing a twin four-lobe high-twist 160 degree helix rotor group to force feed 1.9 liters of intercooled air into the engine, the WP190 produces more usable torque lower in the range at a dramatically more efficient rate (up to 35% more efficient than its predecessor).

Maximum power of the standard kit comes at 9.5 to 10psi boost, although Walkinshaw is willing to discuss even more performance on a case-by-case basis at any of its Australian or international offices. The entire package is enclosed in a special housing by Walkinshaw and comes with a one year/20,000km (12,000mi) warranty as standard.
