BTW, here's some more mud for this particular puddle of water. In the two "screen capture" documents linked earlier (one each at 115 and 120 hp for the KX engine), there is agreement, if you look hard enough. The KW rating for that engine in both documents, is 88. It happens that 88 KW converts to 120 metric (DIN) hp. So... I would have to conclude there's a very strong possibility the 115 hp number is the result of someone using an incorrect conversion factor.
(OTOH, while the 120 hp number appears to be converted correctly, that conversion is to DIN hp, not the SAE net hp we're supposed to be using as the basis for the process. So just for giggles, if 88 KW is correct, we're talking 118 SAE net.)
Anyhow... this all makes me wonder what the KW rating is in all the "other" documents (shop manuals, owner manuals, etc.) that show 110 hp?
