When the pull was over and dyno screen lit up with the results, the Hennessey Performance DynoJet spit out 645rwhp and 653lb.-ft of torque. That’s over 100hp more than a factory ZR1! Hennessey tested their ZR1 back in December and pulled off a very impressive 530rwhp and 524lb.-ft of torque. However Hennessey doesn’t do second rate and they wanted to make sure they had the baddest Camaro in all the land so they cranked the horsepower up to 11 and we think it sounds just perfect.
