I was a diesel mechanic for years, talk about high compression engines.
piston cooling nozzles pumping oil up to the bottom of the aluminum pistons keeps them from overheating, oil ccolers that exchange heat to keep the oil cool, now they all sport turbos, with charge air coolers to keep the intake air temperature down, this all with an average increase in horsepower from 350 now up to 600 and up.
Throw in the fact the old top-stop rocker arm operated injectors have now been replaced with electonically controlled "spark plug" type injectors that are fired via an ECM that reads exhaust, inlet air temperatures to adjust the amount of fuel required, and we have a " fuel efficient" nightmare when a small electrical connector fails.
What we used feeler gauges for on a tune up now is read by a computer talking with an on board computer.
I think a piston cooler squirting oil on the bottom of the piston would solve the non-available forged piston issue. That or we all pool together & have someone start making forged pistons for us. With the oil companies going to lower & lower octanes to keep within federal mandates, we are going to have to find a refinery willing to produce 93 octane just for Ag use. Until we can come up with one, the other or both, a simpler solution must be out there somewhere.
