pulleys

the points of the other cutouts that aren't the circles will cause cracks

you have to use a radius to stop such a thing, not to mention a CNC machine won't be able to make it without the radius...

are there any options for a 2belt lightweight dampened pully?

The ATI dampener is ~5 lbs lighter than stock...the AC pulley can can be removed making it lighter still. Suprarich sells them.

BTW - underdriving the water pump is NOT a good idea.

only time I'd underdrive the water pump would be if you where spinning high enough to cause cavitation...
