John Hennessey has a lot of great things to say about the Hennessey Camaro Z/28 with the HPE600 upgrade, as he takes it out on a drive in this video. But you mostly just hear the car.

The noise from his Z/28 upgrade is just amazing. And it doesn’t look half bad as he takes it around a track at some speed. That’s what 636-horsepower gets you.

But that noise is still just… wow.

Watch it in the test-drive video and hear it even more in the dyno test.
