OK guys I'm looking to replace the belt drive water pump in the C-3 (has 458 hp ) We are looking at going to an underdrive pulley system to drive the power steering pump and the alternator (the brake vacuum booster system runs off the P.S. pump) along with an electric water pump.

Has anyone done the conversion - and are you happy with the results? Any numbers ? Hp increases?
Most importantly - any suggestions - brands kits etc?

Belt and pulley advise?

Thanks

I went with a Proform electric water pump... Works great! HP gain depends on engine rpm. The higher the rpm, the higher the gain. Expect somewhere between a 5 to 15 HP gain..
