Walkinshaw Performance has unleashed a new W375 upgrade kit for naturally-aspirated Gen F HSV models. The kit lifts outputs to the 375kW of power reflected in its name, beyond the standard 317kW, 325kW and 340kW versions of HSV’s 6.2 litre LS3 V8. It also adds at least 106Nm of torque beyond the standard variants, with a new total of 676Nm.
These W375 boosts comes thanks to ceramic coated headers, high-flow catalytic converters, a sonorous stainless steel cat-back exhaust system, a revised cold air intake system, plus ECU revisions to make the most of the kit’s improved breathing ability.
“Our sister company HSV have delivered an incredible vehicle straight out of the box. But for those who want more, our W375 package offers the best naturally aspirated drivability result imaginable,” Walkinshaw Performance General Manager Tony Harris says. “This package puts you in serious European sports car power territory while costing a fraction of the European price.”
Priced at $6,495, the package is signified by a W375 build plate and badging on the rear, and Walkinshaw will back the kit for the duration of HSV’s 3yr/100,000km factory warranty.
The W375 package joins the existing 310kW W310 kit that arrived earlier this year for 6.0 litre V8 VF Commodore models. Walkinshaw Performance hasn’t specified performance gains for the W375 package, but it’s bound to take your Gen F Clubsport, R8, Maloo or Tourer that much closer to the 4.4 second 0-100km/h figure of the supercharged 430kW, but $92,990 HSV GTS.
