Hellcat on chassis dyno

You know... Its actually just making more HP than you are giving the Hellcat credit for. Lets say that the car has a 12% driveline loss (that is more realistic yes?). So doing the math you take rear wheel HP @ 650 and divide that by .88 = a crank HP of 738.6.

Hauling that 4440# lug around at the ET & speeds we all have been seeing probably takes more than the advertised 707HP. See how they do that? The 707 advertised rating is simply a tad low.
