Does anybody try to get the point. We are changing the gearing, or even the tires to turn the 4 banger motor slower. the same amount of cylinders is firing a minute. the reliability comes from a 4 turning at 2400 rpm and a 3 turning 3200 rpm. they are doing the same job but which would last longer. the effeciency comes from now turning the accesories slower like an underdrive pulley would. I do really like the destroke idea, along with the xfi cam (which would go in the engine evenwithout a destroke).
