Re: Rotational Weight Question
Unfortunately, there's not a hard fast rule for the question you ask.
You need to look at the rotational weight AND the effective gear ratio to truly determine the gain you might see.
Translated, rotational weight removed between the tail shaft of the transmission and the tires is not very effective.
Rotational weight removed in the transmission is very effective. Ask the guys Pro Trans or Scott McClay if reducing transmission rotational weight is effective. You won't see the gain in mile per hour, but the lighter transmission will ET better.
Rotational weight of the engine is even better than the transmission. Ask the quick stick guys if they like a light or heavy flywheel.
Reciprocating weight of the engine is beyond my understanding to say how much better it is. I tried to figure it out once but it was beyond my ability to comprehend. But lighter is better.
