To conclude; the reports are consistent that the P-47 wasn't as good at power-dive as it was publicized, in fact it was worse in respect to it's maximum safe dive speed than it's contemporaries by a considerable margin. Although being heavy, very good at accelerating on initial dive.

I could add this reference, that supports your statement: http://www.wwiiaircraftperformance.org/t...I-cfe.html

It's a Tempest II tactical trials report (May 1945) that says:
- "49. Dive: The two aircraft are identical" when comparing Tempest II with Tempest V
- "59. Dive: The Tempest II always out-dives the Thunderbolt, the advantage being more marked at full throttle" when comparing Tempest II with P-47

So, according to this document P-47 was inferior in a dive to Tempest V (and to post-war operational Tempest II too).
