[QUOTE=oil pan 4;378547]I finely got around to measuring how much power it takes to turn a P/S pump.
It looks like if you can keep the P/S turning at 850rpms it takes hardly any power to turn, around 150 to 200 watts.
But when you bring it up to a more normal cruse speed say about 2,000 rpms power draw goes up quite a bit. It took a little over 500 watts to keep it turning at that speed.
For my suburban 500w gets about a half MPG.
I'm going with a clutched setup.
I seen where you posted on a diff thread about this. was this just free circulating into a bucket or beltless on vehicle test?
