Currently, Walkinshaw Performance is involved with various forms motorsport and also the manufacture of high-powered Holden Commodore sedans. The company’s latest W375 Package is designed for the already extreme HSV Gen F range, based on the Commodore, and takes the cars’ 6.2-liter LS3 V-8 engines and extracts 502 horsepower and 498 pound-feet of torque from them--without the aid of forced induction.
The upgrades include ceramic-coated headers, a high-flow exhaust, a cold-air intake and a recalibrated ECU. Walkinshaw Performance also puts each car on the dyno to ensure claimed performance levels are reached.
The LS3-powered Commodore will be sold in the U.S. later this year as the 2014 Chevrolet SS, but output will be capped at 415 horsepower and 415 pound-feet of torque. We’d like to see Walkinshaw Performance offer its W375 Package in the U.S., though we’re doubtful of it ever happening.
If you’re lucky enough to live in a market where Walkinshaw Performance products are sold, the W375 Package will cost you around $6k. Not a bad deal considering the improved performance.
