If you're the kind of guy that thinks a 430kW car could do with a bit more juice, Walkinshaw Performance wants to talk to you.

Releasing its 77kW/110Nm upgrade package for the HSV GTS sedan and GTS Maloo, Walkinshaw have taken the HSV flagship above the 500kW mark for the first time.

For just $7990 fitted, your GTS could have a grand total of 507kW at 6200rpm and 850Nm at 4400rpm.

Those are big numbers in anyones language. Supercar numbers, in fact.So how does Walkinshaw do it?

By increasing boost from the 6.2 litre LS2 V8's supercharger with a different pulley, tweaking ignition and fuel settings in the ECU, changing the headers for free-flowing ceramic-coated items and adding a low-restriction intake and exhaust.

The rest of the driveline is unchanged, and Walkinshaw says is perfectly capable of supporting the W507's incredible output. You'll also retain the balance of your car's warranty.

Walkinshaw Performance General Manager Tony Harris says the W507 package "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," Harris said.

Supply wil lbe constrained, however Harris says interest is already strong with over 200 orders already placed - enough to keep Walkinshaw busy until the end of February.
