By fitting the supercharged HPE650 package to the Camaro Fifty, HPE raised the power output to 589.55 horsepower and 500.93 lb-ft of torque at the rear wheels. This gives the car ZL1-like power, which translates into fantastic acceleration. The 0-60 time of the Camaro SS with this upgrade is actually 0.2 seconds quicker than that of the ZL1. This enables the Camaro to run down the quarter mile in 11.5 seconds, with a trap speed of 124 mph. The top speed is also raised to 190 mph.
