Walkinshaw Performance is preparing to launch a supercharged Chevrolet Silverado 1500.

The sister company to HSV teased an audio file of a supercharged V8 on Instagram (below), with a spokesperson for Walkinshaw confirming to CarAdvice the high-performance Chevrolet Silverado will arrive in the first quarter of 2021.

A distinctive supercharger whine can be heard as the engine is taken up to its redline on a dyno, as the company finalises calibration.

HSV models of the past decade used the previous generation of the 6.2-litre petrol V8 currently fitted to the Chevrolet Silverado 1500, meaning local development of the new Chevy supercharger kit could be fast-tracked for our market, given the pre-existing local knowledge of the 'small-block' engine architecture's workings.

While details have yet to be released, it's expected the kit will deliver well in excess of 500kW – an increase of more than 50 per cent over the Silverado's current output of 313kW. Torque is thought to jump from 624Nm to more than 850Nm.

In 2015, Walkinshaw's aftermarket supercharger kit upped performance figures of the Holden Commodore SS from 304kW/570Nm to 547kW/880Nm, for just shy of $26,000 fitted.

The Silverado's supercharger kit will be offered as part of the company's 'Fury Pack' for the American pick-up, the company has confirmed, which adds a sports exhaust, a 2-inch (51mm) suspension lift, 18- or 20-inch alloy wheels, an optional brake upgrade, and some visual add-ons.
