Walkinshaw Performance has introduced their new W507 package for the HSV GTS and Maloo GTS.
Designed to give the cars plenty of extra kick, the package includes a cold air intake, a cat back exhaust system, ceramic coated headers and an upgraded pulley. There's also an optimized ECU, decals and a certificate of authenticity.
The package costs $7,990 AUD ($6,566 USD / €5,248) and enables the supercharged 6.2-liter LSA V8 engine to develop 689 PS (680 bhp / 507 kW) and 850 Nm (626 lb-ft) of torque.
According to Walkinshaw General Manager Tony Harris, “This is the best engineered package we have ever produced. It feels incredibly powerful, even more than the 507kW indicated, and that is due to how each component in the package has been designed to complement each other.”
