The Super Sport (SS) nomenclature has represented many variants within the Chevrolet lineup, ranging from performance packages to “Lick’em-Stick’em” marketing techniques. Between 2013 and 2017, “The Chevrolet SS” stood for a hot little sedan sent over to the United States from the land down under, where it was known as the Holden Commodore. Although, this BoostDistrict SS is quite a bit more “Red Hot” than when it left the factory.
At the heart of the Chevy SS was the torquey 6.2L V8 known as the LS3, which had been used in Corvettes since 2008 and is considered by many as one of Chevrolet’s best and most versatile engines. In Chevy’s sporty sedan SS, the LS3 was rated at 415 horsepower, which was plenty of power for an aspiring 19-year-old enthusiast such as Roshan Poptani.
While on a trip to visit a friend, Roshan stopped by a local Chevrolet dealership and spotted this 2015 Chevy SS languishing on the lot. The car came in late that year, and the 2016 models soon up-staged the brand new, but not as new car. Roshan admits that he has a soft spot for sedans, and the car’s color, entitled “Some Like It Hot Red Metallic,” describes him perfectly.
Roshan purchased the car with only 300 miles on the odometer and almost instantly began making it more to his liking. At 3,800 miles, Roshan disassembled it in preparation for a cam, full exhaust, and a supercharger before the car had its first oil change! He started the task Friday night after work and had to have it running by Sunday evening so he could go back to work on Monday!

Six years have passed since Poptani drained the OEM oil for the car’s first engine upgrade. Since then, the vehicle has undergone several stages in the progression to its current status. The earliest modifications included the cam, exhaust, and supercharger, which helped the LS3 produce approximately 650 horsepower to the wheels thanks to 10 psi of boost. The next power iteration came from a Gen-I prototype 2650 supercharger that produced 17 psi and around 800 horsepower at the wheels. Then, wanting even more, Roshan built a forged 6.0L to withstand more boost and made over 900 horsepower to the pavement.
Bigger IS Better!
As we all know, there is no replacement for displacement, and even with Roshan’s boost gauge well into the double-digits, he still wanted more. That’s when the boring bar came…
