This weekend I had some time to remove the water pump pulley from the Metro and measure it up. It looks like it'll be a little tighter than I had initially thought, but still plenty of room.
Here are some pics:
This is the clearance between the water pump and the frame.
This is the OEM water pump pulley removed. WOW the water pump is ridiculously easy to spin by hand. It spins and coasts. It'll be interesting to see how much power the pump actually draws once its spinning a few thousand rpm.
Here we have the bolt centers measured up so I can update my pulley design with the correct spacing. I'll also be incorporating 2000mc's idea of adding a hole in the center to aid in cooling.
