According to the type certificate data sheet for the Pratt and Whitney
62,000 thrust engine, the max continuous thrust should be ~52,000 and
the 62,000 for 5 minutes max. The question is, does N1 @ 100% produce
52,000 lbs of thrust or does it produce 60,200 lbs of thurst? Any
airline pilots out there that can shed light on this?
Thanks, Kevin

Why do you ask Kevin? Are you putting a PW4000 on a homebuilt? G
