for my application that would be 420rwhp * 5% = 21 extra RWHP. Assumed across most of the powerband which is VERY important and noticeable.
Not to mention longer joint life due to less lash pounding of its own weight-( I would think?).

The alloy yokes were definatly sturdy and light.....but a pretty large diameter.
