Does anyone have specs on the flow rate of the power steering pump for the (in my particular case) the 94-97 defenders? I know that the serp pump and the v-belt pumps are different as I did a front cover swap, but I bet the flow rates are pretty similar.
The reason I ask is that I recently did an LS swap and I know the LS pump puts out about 3-3.9 gpm depending on the exact pump, closer to 3.5gpm for my particular case. When I initiate turning, the turning is too quick--feels twitchy like it is going to turn too fast and keep turning. Since my steering box is the original Land Rover one, it could be the flow rate as it didn't do that before and my alignment is unchanged and still correct (I checked). I know I can go more toe-in to correct twitchy steering, but I don't think that is it. If it is an increased pump flow rate, that would cause it too.
Quote from DSE website:
This flow correction fitting will reduce flow from 3 gal/min to approximately 2 gal/min while retaining the appropriate pressure in the system. This flow correction fitting should be used when a GM power steering pump is used with a Mustang II rack and pinion.
Tech Tip: A power steering pump with a 3 gal/min flow rate can overboost a Ford rack and pinion. The steering will feel "twitchy" or "nervous" if our flow correction fitting is not used.

I am thinking of trying that. But I also wanted to know if the other pump (and our boxes) wanted a lower flow rate than I am currently running. Anyone know? I called Meridian (who rebuilt my box) but they are absolutely not wanting to even talk about anything technical--boy did they change...
