Probably a daft question but where's the best place to get a N1 Water pump? I've seen some on Ebay but to be honest i'm a bit reluctant about the quality of the product.
Are you sure about that?Provides a higher flow rate so better cooling under load
That is right, Cavitation (Foaming of the water) can affect the engine cooling at high revs.Are you sure about that?
Looking at the design, I would say the Stock one flows more.
The N1 is supposed to flow better at high RPM's as the stock one suffers from cavitation at high speeds. ...............But that is something I read off the internet, so who knows if it is true.
