I have a friend that use his car for rally and we are looking for a typical function for cooling the head piston tipicall on rally cars

when you close the throtle on high RPMs (high RPMs and low MAP) it inject fuel for cooling head pistons

Overrun fuel will wash the bore down.

Honda uses an oil jet for piston cooling.

Another way is having the connecting rods EDM-drilled. It lubricates the wrist pin and the excess splashes around on the bottom of the piston crown.
