Explicit resolution reports before identified causes, performed actions and suggestions. Within each level, matching component labels precede direct query mentions and inherited thread context; successful versus unsuccessful discussion counts, owner confirmations and independent discussion support determine order. This is not a probability of success.

My understanding is the power steering gear orifice changes based on vehicle speed so even though Lon increases as rpm increases, the amount allowed to affect the steering gear is reduced as speed increases.

I'd like to replace with an electronic hydraulic pump, but I need some specs and can't seem to find any.

These are separate views of the same evidence. Frequency alone does not establish a fix, and these counts must not be added together.

Coverage and how to read this overview

Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

5 eligible posts · 0 unverified posts · 1 discussions match the subject in their title or opening post.

POST 1 / ORIGINAL POSTEROriginal post

Does anyone know what the flow rate is for the 2002 996 C2 stock steering pump? It should be rated in liters per minute or equivalent. I'd like to replace with an electronic hydraulic pump, but I need some specs and can't seem to find any. Its for this project, BTW: http://kurtsprojects.blogspot.com Thanks for your help! -K

POST 2Original post

Actually the pump would be rated for liters/rev or liters/min at a given rpm since the pump rpm and flowrate varies with engine rpm. How will you manage flowrate at different speeds with the electric pump? Do you just size it for the max rate? I am not sure what this would do for your steering feel.

POST 3 / ORIGINAL POSTEROriginal post

I agree lpm vs rpm is a graph I have seen for other pumps. My understanding is the power steering gear orifice changes based on vehicle speed so even though Lon increases as rpm increases, the amount allowed to affect the steering gear is reduced as speed increases.

POST 4Original post

Don't know the flow rates but you might try renegadehybrids.com .They have an electric power steering conversion kit .

Hi Kurt. Interesting project you have going. I've bookmarked your BLOG, and look forward to following your progress.
