Another 2010 SS Camaro we just did. This car came to us & had a previously installed, Airaid intake, camshaft (specs unknown) & a single disc stall converter. We weren't able to get horsepower numbers before we started because the car had been taken apart & wasn't running. We installed a ZL1 supercharger with an ADM performance 2.75 upper pulley, a ZL1 fuel pump, an ADM Performance fuel pressure control module, Rotofab cold air intake & ID 850 fuel injectors. It makes 620 (rwhp) horsepower on 91 octane through the 6 speed automatic transmission, very quick, fun & fast car!
