Magnuson is proud to announce our HeartBeat supercharger system for the 2010-2015 Chevy Camaro LS3 and L99. At just 6 psi, the Heartbeat adds over 125hp to the wheels. On our test car, a completely stock 2014 Camaro SS 1LE, bolting on the Heartbeat supercharger added 140hp to the wheels for a total of 530 rwhp (roughly 625 hp at the crank) on our Mustang dyno.
