That's a quite a bit longer stroke than usually. Do any gurus know why we have do it this way?
I suspect that your engine runs much lower rpms than F1 racing engines and that stroke to rod ratios are also much different. Slow revving long stroke engines produce more low power torque as you see in tractors or ship engines. Your engines are made for ultimate efficiency. So the assumption is that they have a good thermal and internal aero efficiency as well due to the slow speeds. I would be surprised if your engines run more than 1,000 rpm. Probably they are even under that.
