2016 Chevrolet SS – Whipple Supercharged

Chevrolet | SS : May 9, 2020

Devon brought us his 2016 Chevrolet SS to inject a little Australian HSV GTS spirit (i.e., BOOST) into this displaced Holden Commodore VF!

Up first, John performed pre-work dyno pulls to establish our starting point (baselining at 391.08whp & 391.49lbft), then she went to the shop for Louis to set the LS3 up with a 2.9L W175AX twin-screw unit from Whipple Superchargers connecting nicely to the existing air-intake system from Roto-Fab, LLC, 1.825″ primary OD long-tube headers from Kooks Headers and Exhaust Cerakoted by Detective Coating, TR6 spark plugs from NGK Spark Plugs, spark plug wires from MSD Performance wrapped in Protect-a-Boots from Design Engineering, Inc., dual valve spring & steel retainer set from Total Engine Airflow, rocker arm bronze bushing trunnion upgrade from Smith Brothers Pushrods, 160° thermostat from Lingenfelter Performance Engineering, a Mild catch can setup from Mightymouse Solutions, along with the miscellaneous OEM and aftermarket odds-and-ends to bring it all together.

With the mechanical work wrapped in the shop, John strapped her down to the rollers for Vlad to perform a custom calibration via HP Tuners. With 93 octane in the tank, and the Whipple 2.9L delivering ~11psi, Vlad increased the boosted LS3’s output to 623.63whp & 579.63lbft through the automatic 6L80E transmission — a gain of 232.55whp & 188.14lbft! And that’s how you make the motherland of ‘Straya proud, mate.
