The factor is more like .83 for the 4.7L PowerTech V-8. I will need to
prove this on a Dyno run in April (Escondido area). I have seen the Dyno on
a GC Jeep with a 4.7 and it read around 195 at the rear (stock).

Subject: Re: DML: HP AND TORQUE NEEDED
I believe it is rated at 250 hp, 335 Ft./lbs.s of
torque, or roughly.. 250 x .8 = 200 hp at the wheels,
and 335 x .8 = 268 ft./lbs. of torque. That's real
close, as my '00 RT stock did 203 hp @ 270 ft/lbs...
I recently dyno'd it again after headers, 1.7s, and
Gen II.. 227 hp & 320 ft/lbs... or 227 /.8= 283.5 hp
and 320 /.8 = 400 ft/lbs at the flywheel. Probably
+-5% of those figures would be a good range. The 4.7L
with a 5 spd would be hp x .82 to get rwl HP/torque.
