...not if you're using big doses of nitrous or cramming a ton of boost in the cylinders.  Hypereutectic pistons work fine for stock type replacement pistons in the daily commuter. For any serious effort a quality forged piston is the only way to go.

This is something that has troubled me for a long time and i've never heard it explained to my satisfaction .... the cylinder walls and to some extent the cam lobes (not journals) get lubed by oil splashed up from the crank counterweights. So when you put a deep sump pan (lower oil level) or a windage tray in you lose that splashing oil. So now how do the lower cylinder walls and cam lobes get lubed ???
As to the Hypereutectic piston thing ... i don't think you guys are giving nearly enough credit to the new technology in Hyper pistons. They have vastly improved ... true, if you're gonna build a monster 8,000 RPM motor or one thats gonna get a huge dose of nitrous or ton of boost, the forged pistons give you a lot bigger safety margin (will tolerate detonation longer before meltdown)... but the newer high performance Hypereutectic pistons will hold up to all but the most punishing of motors, and they are quite a bit more streetable (you can run them much tighter because they don't expand when heated nearly as much)... so they don't slap when they're cold.
