It's fine IMNSHO to go a bit off topic, but to deny the original topic altogether is just plain wrong.
Me thinks you're getting your back up because Greg Lee is a pedantic grammar nazi (not that there's anything wrong with that
).

The problem is that until someone on the Honda engine design teams posts, we are working with a puzzle of both mechanical and psychological issues, and have only information on the f20c as a starting point.

if someone can give me the rod length of the engines (F20c and F22C) and the stroke of the engines, i can create some graphs so we can see what the accleration(and forces) on the pistons would be at 9000

I don't think the accel is supposed to be symmetrical due to the changeing angle of the connecting rod. The acceleration of the crank is symmetrical, however the acceleration of the pistion (which is what I was going after with the equation) is the acceleration of the crank, plus the acceleration of the pistion relative to the point on the crank where the con rod is attached. (Relitive to the crank attachment point, the pistion sweeps out an arc with a radius = to length of the con rod)

what have i started. although i understand your point guys it will be hard to decide what components since some have been changed, the crank is changed and comp ratio changed a upwards a bit which i think means pistons are diff too, but im no where as close as smart as you guys so dont take my word for it.
