My Ford Capri 2.0 motor has a stock water pump pulley a little over 4" in dia. I have a 6" dia pulley from a Pinto 2.3 which I'm adapting to fit. I will also be increasing the alternator pulley from approx. 3" to over 5" dia. This change will reduce the speed of my alternator and water pump. The alternator probably won't charge until 2500+rpm but does anybody think I'm going too far with the water pump, reducing the speed by almost 1/3rd? Car has never overheated with the stock pulley.
