I was surprised the RX8 cart. was so light.
It is a lot smaller and probably runs much faster.
The 13B pulley weighs a pound too.

The RX8 housing is also die cast so that saves
a bunch.

Paul,

The 20B water pump at 6.4 lbs is approx. 50% heavier than the 13B pump.
Lots of potential weigh savings here.  Has anyone flow-tested the Renesis
pump?

Not that I know of. The 13B pulley is about 3.7 inch OD.
What is the OD on the RX8 pulley? That will tell us how much
faster it goes.
