Typically, an oil cooler will not increase power, and in fact may actually reduce engine power, as cooler oil is thicker oil, and thus takes MORE energy to pump etc.
However, many modern cars monitor oil temps, and if gets too hot, the computer will start to REDUCE POWER, in an effort to keep oil temps out of the danger zone ...
So, IF the car in question does reduce power when the oil gets too hot, then, YES, an oil cooler could allow the engine to make full power under extreme oil temp conditions. Note... not MORE power, just better use of the engines available max power.
Controlling the oils temp whether a fast warm up or to prevent excessive oil temps yes there is a power gain ,probably not seat of the pants noticeable and this would require a thermostat setup. Not too cool not too hot right in the optimum temp range.
