It is defined by the Physikalisch-Technische Bundesanstalt (PTB)[7] in Braunschweig as exactly:
1 PS = 75 kilopond-meters per second
(75 kp·m/s)×(9.80665 N/kp) = 735.49875 N·m/s ≈ 735.5 N·m/s ≈ 735.5 W ≈ 0.7355 kW ≈ 0.98632 hp (SAE)
The PS was adopted by the Deutsches Institut für Normung (DIN) and then by the automotive industry throughout most of Europe, under varying names. In 1992, the PS was rendered obsolete by EEC directives, when it was replaced by the kilowatt as the official power measuring unit. It is still in use for commercial and advertising purposes, as many customers are not familiar with the use of kilowatts for engines.

Is this supposed to be the answer to my question? Here is a blurb from a link:
In order to discuss powerplants in any depth, it is essential to understand the concepts of POWER and TORQUE.
It often seems that people are confused about the relationship between POWER and TORQUE. For example, we have heard engine builders, camshaft consultants, and other technical experts ask customers:
"Do you want your engine to make HORSEPOWER or TORQUE?"
And the question is posed in a tone which strongly suggests that these experts believe power and torque are somehow mutually exclusive.
In fact, the opposite is true, and you should be clear on these facts:
1.POWER (the rate of doing WORK) is dependent on TORQUE and RPM.
2.TORQUE and RPM are the MEASURED quantities of engine output.
3.POWER is CALCULATED from torque and RPM, by the following equation:
HP = Torque x RPM ÷ 5252

So using the simple HP equation at the bottom of the blurb the answer is obvious, in order to get more HP with the same torque output you need to increase RPM, thats it.
