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.

    Would be nice to know how much and what we can expect in added horsepower.No idea why they would want to make it quieter though.I would say seems kind of odd there’s no power figure, considering that’s the whole point…!
