Sorry for the delay but here is the page out of the TAIC manual....I added the normal (continuous) rated from one of the aircraft data sheets.
Yes WEP is obtained thru ADI. The numbers followed by the * are estimated by TAIC. It appears all ratings are at non-ram altitudes.
Hope this helps. Imagine if the Zero designers had stayed with the Kinsei 44 from the beginning instead of the Sakae, the Kinsei 62 could have been installed in late 1942 (a.k.a. Zero Model 64).
