What are the benefits or drawbacks if I use hypereutectic pistons in this new 292? The supplier says this about the pistons "...16% silicon. No lead fuel alloy, better ring groove life, 15% less thermo expansion. 1.5mm top and 2nd ring, 3.0 mm oil. 40-60% savings in parasitic ring friction."
My other piston option is a run of the mill Cast unit with 5/64 compression rings and 3/16 oil ring.
Is the life expectancy going to equal standard pistons? Can clearances be tightened up?
