compared to the other factors involved .... not really.Referring to the first post, would the weight of the rotating /reciprocating assembly actually make a difference in torque production?
Any torque production is all about getting and trapping air fuel mixture in the cyl. at any rpm. So how can lightweight pistons have anything to do with the lack of low rpm torque?My question was prompted from a discussion on another site. Someone there was blaming lightweight pistons for lack of low RPM torque production. By low RPM - think 1,500 to 2,000 RPM. More the RPM range where you would be using a diesel IMO.
The trouble is... most would never add reciprocating weight to gain torque because this will limit the engines ability to RPM. But what if you really never did take the engine over 3,500 RPM or so? Would you actually WANT a heavy reciprocating assembly or would you want more rotating mass?
