Ahh, yes, the Chevy SS (no rhyme intended), how we love thee.
No, the car in the video doesn’t appear to be a Chevy SS, and that’s because the owner was smart and installed the Holden Commodore badge kit and front grille. It doesn’t add any horsepower, but for Holden fans, it makes all the difference. This particular LS3-powered big-body sedan was recently at Tune Time Performance in New Jersey for some much-appreciated upgrades, resulting in a great horsepower bump over the factory numbers.
When the SS was in the shop, the crew at Tune Time installed a 4.0-liter Whipple supercharger, Tune Time CNC heads, a Tune Time Stealth Blower Cam, and American Racing headers and mufflers. With every piece of new hardware installed, the car went onto the automotive lie detector to see what kind of power was made. As the car gets rolling on the dyno, it becomes more apparent that the American Racing headers and mufflers make the car sound like a total animal, and we love it.
Pulls one, two, and three were all really consistent, and the blower was at 8 PSI for all three runs. The shop claims that they made 245 horsepower over the factory numbers, which seems about right considering the SS’s LS3 makes 415 at the crank and about 360 horsepower at the wheels with an estimated drivetrain loss of about 15 percent. The SS is a great car and it can only get better from here, provided Chevrolet keeps it in the lineup. We hope they do because it’s the closest thing we have to a Holden Commodore.
