I know the stock Power is (SAE) 332 hp @ 7,000 rpm; 270 ft lb of torque @ 5,200 rpm in a perfect world.

What would be your guess for HP at 65ºF and 100ºF for a stock 370z?

The ECU starts limiting power when the Intake Air Temperature gets to ~85-95 F. You are not gaining power at lower ambient temps, the ECU is restoring normal operation. The question should be: How much power am I losing at 100 F? (My answer is: I dunno.)
