I headed out to MSR Houston last weekend to visit friend of S:S:L, Michael Mills, and was pleasantly surprised to see John Hennessey and John Heinricy testing out their latest creations. The ZR700 is a tweaked version of the already potent ZR1. Hennessey claims 705 horsepower with the upgrades. The top video is one I shot from the end of pit wall as the ZR700 entered turn 1 at MSR Houston. The in-car video below is by Hennessey Performance and shows John Heinricy in action. Enjoy!
