It must be a pretty sweet feeling to drive a car with your name on it. John Hennessey is fortunate to be able to do that every day and last week he took out the 2015 Camaro Z/28 upgraded with his very own HPE650 package. This provides the LS7 engine with 650 hp and, as you will hear, an unforgettable soundtrack. Awesome straight line speed is matched by phenomenal stopping power thanks to a set of carbon ceramic brakes, but this upgrade is all about the supercharger giving the 7.0-liter V8 insane levels of performance.

Hennessey thrashes the car so hard, OnStar called him to make sure everything is OK. His response is priceless. Check it out.
