Thread: Water pump question

Will this cause cavitation its on a N1 engine so N1 pump and a underdrive pulley as standard, and does anyone have the measurements of the diameter of the inner and outer crank pulleys and a gspec underdrive pulley

i don't think you will have a problem with that setup.

Do you have the belt on the outer crank pulley? That's going to be a bad idea for the water pump. It will spin much too quickly. You have the water pump pulley on backwards?
I would use two belts...

I have seen it done that way on a couple SCCA race cars ... they had to notch the frame to fit the water pump pulley when on backwards .... seems to work ok for them ...

Ill have to change it I will not notch the frame. I will be running a meziere pump when funds allow things are tight at the moment cars getting too much spent on it
