Or change the size of the alternator pulley - its basically a simple ratio thing - a smaller dia alternator pulley in relation to the crankshaft will drive the alternator faster, and a larger one will drive the alternator slower with a given crankshaft speed. This is true only for the alternator in this case. The same holds true for the water pump if you change the pulley on that, but again, it will only affect the water pump in this case. However, if you change the crankshaft pulley, that will affect the speed of everything it drives. if you use a smaller diameter crankshaft pulley, and change nothing else, everything it drives will run slower, and if you make it lager everything it drives will run faster ***********************************- >Joe Curry said: >> So, while I am in the market for a new pump, I decided to >> order one designed for a later car with an alternator >> (larger pulley). > >Ummmm, Joe, I'm not looking at my Spitfire right now but from memory and with the knowledge of just about every other car I've ever seen... > >The water pump and alternator are driven by the crankshaft pulley. So changing the water pump pulley size won't change the rate at which the alternator is driven, merely slow down the speed of the water pump (and require a larger belt). If you want the alternator turned faster you'll need to replace the crankshaft pulley with a larger one.
