Oil pumps

[TimT]

Anyone have the specs for the various oil pumps used in a 911?

Im most interested in a GPH spec.

I have a 930 pump in my 2.2

I may be able to get my greedy paws on a GT3 pump. If this pump flows like i think it does I will be installing a racor oil filtration system... a racor full flow/w a bypass filter as well..

Just my way of making a bullet proof 8000rpm 2.2

The 930 is generally considered to be a pretty d*** good pump. I doubt that you need anything more.

The only basic requirement was established by Smokey U. ie 10 lbs for every 1000 rpm. Do that and your engine will survive. Only trick is to keep out the air bubbles.

I recently found out that the 930 pump is about 8mm longer on the pressure side than the other pumps. The 964 pump has the same size pressure side as the rest of the pumps.

The info I have from Porsche lists oil pressure after the springs and pistons...
