That is why the HP vs Torque curves must cross at 5252 rpm, and it is also why Torque generally cannot remain constant as HP increases beyond that rpm.
How I'm I being misled? While I do agree hp is a product of tq using the formula, tq falling off has nothing to do with the formula and all to do with the efficiency of the engine. Look at a mid-80's Chevy Crossfire, tq will fall off WAY before 5252. Then look at an S2000, peak tq happens way after 5252.
