Hennessey 2017 Camaro ZL1 Gains Over 100 HP Like It's Nothing, Sounds Explosive

Last month, Hennessey Performance offered us a taste of its 750 hp 2017 Chevrolet Camaro ZL1 package. The Texan developer is now back in the game, this time taking the rear-wheel figures of the muscle beast even further.

On paper (make it the screen, if you must), we're dealing with the HPE750, package, which makes for a crank output of 750 ponies.

Nevertheless, the Lone Star State developer strapped the gym-visiting ZL1 to the dyno, with the results being richer than those announced last month. We're dealing with an output premium of over 100 hp and 130 lb-ft at the rear wheels.

In theory, we should multiply those figures with 1.15 to find out the muscle boost at the crank, but that coefficient is approximate, taking into account the losses experienced when using an automatic tranny. However, the Chevrolet Camaro ZL1 we have here comes with a manual tranny, as you'll be able to see in the piece of footage at the bottom of the page.

The goodies included in the HPE750 package include the obvious ECU remap, along with a few hardware changes that allow the new software to make the most out of the blown 6.2-liter V8 mill of the machine.

The heart of the Camaro ZL1 has been gifted with a cold air induction, long-tube headers built from stainless steel, as well as a lower pulley and belt upgrade. As a result, the V8 now works with 12 psi of boost.

The dyno run delivered by the piece of footage at the bottom of the page allows us to get a good taste of this Camaro ZL1's aural might. The Corvette Z06-borrowed engine screams like a bat out of supercharged hell, delivering nothing short of a decibel fest.

The clip also involves the dyno charts, which means you can check out the gains throughout the rev range.

If only such packages would include a complimentary set of rear tires...
