It was a perfect day for dyno runs, and the Hellcat boys were all pretty cool guys to talk with. Those cars are making some serious jam.....the two stock Hellcats were putting down 640 RWHP on the Mustang Dyno (Mustang AWD-1750 Dyno). The biggest number came from a 2017 Hellcat Challenger with upper and lower pullies and a tune........he put down 780 at the wheels!
My car made 469 RWHP and 463 RWTQ. The stock Callaway tune looked pretty rich above 4000 rpm (10.4 : 1) so I know I've got some room for improvement once my warranty runs out
