This 650+ HP Z/28 Camaro Pulled So Many Gs, So It Called OnStar Thinking It Was In An Incident
The sound that this Hennessy Modified Camaro makes is just insane. You better put on some pampers just in case before taking a ride with this speed demon. The stock Z/28 Camaro is also pretty wild but with the touch from the team at Hennessy, you feel a little scared when you hear the exhaust roar coming from this 650-horsepower Chevy Camaro. The car is really fast, we mean so fast that while John Hennessey was testing it, OnStar called him to check if everything was OK.
Let’s see what we got in this HPE 650 package according to the stock Z/28. The stock Chevrolet Camaro Z/28 is equipped with a 7.0-liter LS7 engine under the hood. The LS7 is based on the Gen IV architecture producing 505 horsepower when reaching 6300 RPM. The peak output is 470 lb. ft. of torque at 4800 RPM. One interesting fact about this engine is that it is hand-built by the General Motors Performance Build Center in Wixom, Michigan. Most of engines are installed in Corvette Z06 or sold as crate engines to individuals for project cars.
This engine is not installed only in Chevrolet Corvette Z06, you could find it in cars like Hennessey Venom GT, 2015 Chevrolet Camaro Z/28, Vertical Hummingbird helicopter or 2007 CSV GTS. On the other hand Hennessey created a special package for one of these cars: 2014 – 2015 Chevrolet Camaro Z/28. The package is called HPE650 upgrade. After purchasing and installing the package you could feel all 667 horsepower reaching 7,000 RPM. And this is just the beginning.
