WALKINSHAW PERFORMANCE has announced a new addition to its product line-up: the new WP190 Supercharger. Developed for use with the GM LS3 V8 found in HSV’s V8 range, the WP190 succeeds the WP122 Supercharger.

Walkinshaw says the new supercharger is good for drawing up to 422kW and 727Nm of torque out of the LS3 V8. Utilising Eaton’s Twin Vortices Series “twin four-lobe high-twist 160º helix rotor group” to force 1.9 litres of intercooled air into the big V8, the WP190 produces more useable low-down torque.

WPP describes its new supercharger as being up to 35 percent more efficient than the outgoing model.

Maximum power with the standard WP190 Supercharger kit - which includes intake manifold, water-to-air intercool, high-flow injectors, cold-air intake and ECU recalibration - comes at 9.5 to 10psi boost. Walkinshaw Performance also offers custom projects to produce even greater power.

The new WP190 Supercharger kit comes with a one year/20,000km warranty as standard.
