Last month, Hennessey Performance offered us a taste of its 750 horsepower 2017 Chevrolet Camaro ZL1 package. The Texan developer is now back in the game, and this time taking the rear-wheel figures of the muscle beast even further.
On paper (make it the screen, if you must), we are dealing with the HPE750, package, which makes for a crank output of 750 hp.
Nevertheless, the Lone Star State developer strapped a gym-visiting ZL1 to the dyno, with the results being richer than those announced last month. We are dealing with an output premium of over 100 horsepower and 130 lb-ft at rear wheels.
In theory, we should multiply those figures with 1.15 to find out the muscle boost at the crank, and that coefficient is approximate, taking into account the losses experienced when using the automatic tranny. However, the Chevrolet Camaro ZL1 we have here comes with the manual tranny, as you’ll be able to see in this video.
The goodies included in the HPE750 package include the obvious ECU remap, along with the 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 a Camaro ZL1 has been gifted with the cold air induction, long-tube headers built from stainless steel, as well as the lower pulley and belt upgrade. As the result, the V8 now works with 12 psi of boost.
The dyno run delivered by this video allows us to get a good taste of this Camaro ZL1’s aural might.
