How many of you are using gear pumps instead of diaphragm types and what filter element (micron) sizes are you using?

I think this is an interesting topic as well. You can always look at how Porsche did it with the 915 as a starting point. If I remember correctly, it used a gear type pump housed in the end cover, driven off the input shaft and a spray bar in the racing versions. I don't know if the factory system used a screen/filter.
WEVO has their own solution for the 915 and it includes a particulate screen. Not sure of the details on that screen, but their solution uses a Weldon Racing pump. If you goto their website... http://www.weldonracing.com They list a 100 micron filter/screen for their oil pumps. Also they don't say exactly what their pump design is, but it says no plastic parts, so I am wondering if that means it is not diaphram based. All of this is 915 related and I expect you would have to roll your own for a 901/911/914 transmission as I don't think there are many (any?) off the shelf solutions out there. Richard |
