Stop in for a cup of coffee

when I was working as a dyno tester, we normally figured on a 25-35% drop in power at the rear wheels vs flywheel power depending on transmission and type. More power loss in new autos than older ones.
Hey Chris, FYI...the modern Mopars (like my SRT) have drive train losses more in the 15-18% range. For my '06 SRT it is around 16%.

The Hellcat is down in the 12-15% range.
