What does it do for a naturally-aspirated Gen-F? The name is a not-so-subtle clue. Walkinshaw's exhaust, intake and ECU modifications net W375-equipped HSVs a huge 375kW of power and 676Nm of torque - big numbers in any language.
That's still well shy of the flagship GTS' 430kW and 740Nm, but 35kW and a whopping 106Nm over the next most powerful Gen-F - the Clubsport/Maloo R8 with the SV Enhanced package.
The W375 package retails for $6495 and can be applied to any non-GTS Gen-F HSV.
For your money, you get a new exhaust system consisting of ceramic coated headers, high-flow catalytic converters and stainless steel piping from the catalysts back.
A low-restriction intake and a Walkinshaw-developed ECU tune round out the rest of the powertrain mods, while a Walkinshaw build plate and boot lid badging lets others know you're packing a few more horses under the bonnet.
Don't have a Gen-F HSV, but want to screw a bit more performance out of your VF Commodore SS? Luckily, Walkinshaw has you covered there as well.
