We need to remember how highly variable chassis dynos are. There will be readings all over the map. I find chassis dynos only to be good for baselining a car you plan to modify, assuming you use the same dyno for your post modification test. To put a car on a dyno and then back-calculate flywheel HP is hogwash. No doubt that Ford is getting every one of those 662 HP and the same for Chevrolet and the 580 HP the ZL1 puts out. I struggle when I hear people speculating about flywheel HP based on chassis dyno results. Too much variability to get good relaibale data. Take it for what it is worth. Trust me. I know what I speak of here.
