How much power with a manual water pump?

Anyone producing 625-650 hp and running a manual (crank driven) water pump on a street car?

Which pump?
Any issues?
Any failures?
Any success??

Thanks!

Yeah sure, why not? I run manual water pumps on both of my cars and they both have stroker big blocks making more than 600 hp. The Duster has a Cordoba radiator with shroud and clutch fan. All set up like the factory would've done it.
