About the HSV GTS Walkinshaw Performance W507

Manufactured globally between 2013 and 2017, the Holden Special Vehicles GTS equipped with the Walkinshaw Performance W507 package represents a formidable chapter in Australian high-performance motoring. Taking the already potent supercharged 6.2-litre LSA V8 found in the Gen-F series, this comprehensive enhancement aggressively dials up the output to a staggering 507 kW and 850 Nm of torque through a combination of a modified supercharger pulley, ceramic-coated headers, a high-flow exhaust system, and a bespoke engine calibration. Within the contemporary collector landscape, a genuine, well-documented W507 commands a substantial premium over standard factory examples, maintaining a strong and resilient market value. Its desirability is immensely high amongst enthusiasts who seek a visceral, tyre-shredding driving experience intertwined with the legendary Walkinshaw motorsport pedigree. Consequently, the buyer pool is highly competitive and deeply passionate, consisting predominantly of dedicated Holden aficionados, modern-muscle car investors, and V8 purists who aggressively pursue these immensely powerful super-sedans to serve as the ultimate centrepiece of their local automotive collections.
