Default Power Steering Pump Modification

Hi Guys. Unlike many that have upgraded to the Borgeson steering box, I was not happy with the extra effort required at the steering wheel while driving. Maybe I'm getting too old and have been spoiled by modern rack and pinion daily drivers. I certainly appreciate the more direct feel compared to my original steering system inspite of having totally rebuilt most components previously. At the risk of compromising the feel of the Borgeson box, I wanted to modify my original Saginaw steering pump to provide more pressure and flow than stock. I apologize there are no pictures, but I just followed the instructions on the link below. Prior to starting the project, I was figuring out what was going to be involved in removing the pump to make the necessary modifications but then realized I could remove the fitting and valve from the pump from underneath the car without doing anything else as it relates to the pump. What a pleasant surprise. After the modifications the feel is perfect for my taste. Not too light, not too heavy, but just like Goldilocks said "just right".
Probably not helpful for many out there but wanted to share it none the less.http://73novacustom.blogspot.com/201...p-upgrade.html

This is the first time I’ve heard anyone wanting to raise the pressure or flow, usually it’s the other way around!

I've got a Borgeson kit to install on my car, and from all the prior comments I've read about it people seem either happy with the feel or think it feels too light. I've read very similar comments about the R&P conversions.

I've done some limited research into it, and it seems like reducing the flow is the better way to go to reduce the light feeling. I was going to install the kit with a flow reducer in the PS pump because I prefer a 'heavier' feeling, but after reading your feedback maybe I'll install it as is and go from there. I just hate doing things twice!

I'm curious why your experience seems to be the opposite. Was your car a PS car before the conversion?

My 72 was a power steering car initially and unlike some seemed to perform adequately, however as it is a daily driver, I was looking to extract as much control as possible. I wrestled with either R&P or Borgeson and ultimately went with Borgeson. I have semi coil overs with Global West upper control arms at 5 degrees castor. All components are virtually new. I am thinking maybe my existing Saginaw PS pump could be the weak link, however, the modifications to increase flow and pressure have given me the feel I was looking for. Previously the effort at the wheel was greater than before the conversion. I anticipated just the opposite. I would recommend doing the upgrade and depending on the your assessment, make the changes accordingly. Either way fairly simple to perform. Hope it goes well for you!
