    what do you think the fastest speed i should run my york at? i've decided to remount it and i was thinking on useing the pully that ran the air pump.. right now the yorks pully size is 6" and it runs of the alt pully which is like 2".(thats about 250-300 rpm at idle) The air pump is 6" and would run the york at the same speed as the engine which would be great at idle..

    I've read that the York gets better to around 2500 rpm or so. After that the extra rpm doesnt matter. Mine works pretty well at an idle, but I plan on hooking up a fast idle switch for the York and the alternator.

    If the pulley you run the york off of is the same size as the pulley that the acc. runs off of then you have not changed the speed of the york. If you are going to run the york off of the air pump pulley with a pulley bigger than the air pump pulley then you will increast the speed of the york.

    Actually using a bigger pulley on the york than the one driving it will slow it down (compared to the other pulley). The smaller the pulley the faster it spins (same reason the alternator uses the smallest pulley).

    ok i'am sorry i had a bit of a mental lapse. i thought that i could increase the speed of the york by moveing it to a larger pully. but i forgot that the alt is driven off the same water pump pully of 6". /forums/images/graemlins/crazy.gif /forums/images/graemlins/smirk.gif

    thanks for the link though thats what i was looking for.. i think i'am still might try and work out a pully set-up to get some more rpm's out to the york..

    i've heard the mind goes with age i guess i'am just getting a head start /forums/images/graemlins/smirk.gif /forums/images/graemlins/grin.gif
