Holden/Pontiac SS-V Superwagon, 603 HP of Power
When we see tuner cars like this Walkinshaw Performance Holden Supercharged wagon, based on the Pontiac G8 GXP, a tear sheds from our eyes knowing the end of Pontiac has already passed. Maybe it’s worth it, going to the Land Down unda’ – where the Pontiac-like Holden wagons are still for sale. Walkinshaw decided to take an already enhanced sports wagon and add 603 horse power to it. Crickey!
Walkinshaw’s Superwagon is based on a Holden SS-V Special Edition Sportwagon which comes from the factory with a 362HP 6.0-liter V8 with 390 lb-ft of torque. But Walkinshaw saw that as a starting point, packing on a roots type supercharger, bigger fuel injectors and custom 3-inch exhaust system to raise output to an passenger-rearranging 610 HP and 568 lb-ft of torque. The car also gets a stiffer set of lowering springs, new dampers and 20″ wheels and a powertrain warranty for all the work which matches the length of the original GM warranty.
