Need help with dry sump

I would suggest that the piston oil jets are primarily for piston cooling and have a by product of cylinder wall oiling. If the engine is under high load (WOT) for long periods the piston will soften (age) with time at temperature. The cylinder walls/pistons/rings should be sufficiently lubricated without pistons coolers as there is sufficient flow out flow from the bearings to lubricate these components. Cooling jets are never a bad idea but you should increase the size of the pressure section to compensate for the additional oil flow. All this is best for the engine builder to decide.
