Nobody knows performance like Walkinshaw.

In 2013 Walkinshaw Performance Products, following the launch of Australia’s most powerful road car ever built the HSV GTS, began to scope out a suitable package to compliment this magnificently engineered vehicle.

The journey began in the engineering division with an attempt to fit existing WP Products to the vehicle and it very quickly became evident that this was never going to be an option. The complexity of the design and setup of the LSA powered HSV required a complete rethink from the WPP team.

“There are critical components such as the main wiring loom that without the right clearances in the header area they can be affected overtime by the high heat generated – in excess of 1000 degrees Celsius” lead engineer Andy Richardson noted.

Extensive product development began in earnest. There were numerous iterations of exhaust, header and cat setup as well as a completely revised cold air intake. The pulley upgrade is entirely unique to WPP with the final version selected after comprehensive engine dyno testing.

The ECU calibration completes the package with the testing and fine tuning conducted in a secret locations throughout Victoria. The final testing was conducted in Shepparton Victoria with 20 Gen F GTS owners experiencing the upgrade for the very first time.

“When we set out to do this project we wanted to achieve an upgrade that delivers maximum excitement and great driveability” Richardson said. “The feedback from these GTS owners was invaluable for us but most importantly confirmed we exceeded their expectations with what we have produced.”WP-507-Supercharger-Package-10_full

The final outcome is a package that is completely designed, engineered, and developed by the team at Walkinshaw. “The torque is very linear and delivers on our goal of great driveability. Feedback from the owners centred on the refinement of the package, and a lack of harshness which some had come to expect” added Richardson.

General Manager Tony Harris stated that whilst there were many highlights in the history of Walkinshaw Performance Products “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.”

“As with everything we do the key objective is to engineer a package that exceeds our customer expectations without compromising the vehicle driveability,” Harris said. “Every single component that makes up this package is unique in its design and the pulley is actually manufactured in the Walkinshaw Racing production facility.”

The W507 package availability will be strictly limited prior to Christmas due to supply issues but will free up in the New Year. “There are over 200 orders waiting to be filled and we are confident we will have every one fitted by the end of February,” added Harris.

All products have been developed and engineered by Walkinshaw Performance Engineers to meet the exacting standards and high levels of quality that would be expected from an Original Equipment Manufacturer (OEM).
