Still following, still interested.  So cool to see this project on the road this spring.

Glad to have you  :bigsmile: I haven't had time to do much with it lately, weather turned to crap (got about 16" of snow which is very uncommon here and has caused a lot of drama). I also had to build some hand rails/steps for our refurbished deck (still not done there).

All that said, I have a list of things to do once I get back onto it;

1. replace the plugs (going 1 step hotter)
2. replace the MC (have a new 15/16" bore MC to replace the 1 1/32")
3. modify the clutch pedal (add a bracket to increase the stoke of the rod)
4. turn the T bars down (or move the rear shocks up)
5. remove the PS system and install the OEM one (my "experiment" didn't work)
6. drive the car to let it tune

As stated above, I am going to remove my power steering experiment. For those new to this thread and don't want to read through it all, I elected to use a late model GM PS pump and attempted to develop an adjustable PS system. In theory this would allow me to tune the steering feel. This required me to install a remote reservoir, a regulator and make lines for everything.

I am removing it for 2 reasons, first is that I think the pump is bad, very noisy and second is the space. It is currently a spiderweb of hoses and is far more complicated than it needs to be. The regulator does not work as advertised so there is that as well. Granted, this is a brand new build and I could probably work with it some and perhaps sort it out but to be honest, I just dont like it in its current form.

Seemed like a good idea at the time, but I need to simplify it, thus I am going back to stock.

What fluid are you running in the pump?

I think Im on my third GM Type II pump and this one is finally quiet.

Good question actually, I am running inexpensive O'Reillys house brand. What are you running?

I found these pumps are very particular, while many people are likely "fine" with that type of fluid, it didn't work for me.

As I found out, there's no real standard to what "Power Steering" fluid is, so who knows what it is actually intended for. That said, I completely flushed mine out and use AC Delco (GM) #10-5073 fluid. I've found that PepBoys is the only place around here that stocks it.

In the same breathe, I got pretty serious with my bleeding method this last time. I actually just had PSC go through the pump to address the whine 2 weeks ago.
  • I removed the tie rods from the centerlink to ensure I was getting the full stroke on the steering box.
    • I found that at full lock I'd get the tire just kissing the frame and that may have contributed to my issue last time.
  • I cycled the steering wheel as many times as I could, but ultimately had to start the engine for a second to get the fluid throughout the cooler and back
  • After getting fluid everywhere, turning the wheel allowed me to bleed air, I used an oversize funnel to hold additional fluid and provide more head pressure (as shown)
  • As I churned up the fluid, I let it sit for 10-15minutes and settle so that I didn't continue pushing air around unnecessarily
  • When I actually fired it up, I didn't need to add any fluid, so it must have bled very well that way.

Excellent information. In my case I cannot determine a good reason to run this pump over a factory pump. Going back to the factory pump should lessen the issues and free up a bunch of space. I understand why you are running that pump on your G3, but I don't think I have a good reason to run one on my LA motor.

All this said, I think I smoked this pump by inadvertently connecting it incorrectly. I had the high pressure side of the pump connected to the wrong port on the regulator and when I first started the engine it didn't whine, however once I started working with it and run the engine more it began to make noise. Once I got it all connected correctly (had no PS assist before hand), it did work as far as providing PS assist but not a huge amount (definitely not over driven).

Another issue I may have with is the pulley. When I bought the pump it did not come with a pulley. I bought a pulley from Canton Racing (I believe) and I may have gotten an under driven pulley (larger than stock).

Regardless, I am going to go back to the stock pump and see how that works. Everything is bolt in/on so I can go whatever direction I need to. At this point I need to get to a neutral position when things just work and then I can tweak things to make them better as I go on.

If I recall correctrly, haven't you already had a Firm Feel level three rebuild?  Have you looked at the Borgeson for the space and weight opportunity?

Yes I have, but I am not talking about the steering box, rather the PS pump.

LOL no worries. I've done the same thing far too many times myself.

Its been a little while since I posted on this thread which is a result of a lack of work on my part. You would think that since I got it running and driving I would be all excited to get it finished, however that was not the case as the weather and domestic duties somewhat stole my enthusiasm. That said, I have been doing some small things to move forward. I removed all of my "high speed" PS system as I was not happy with it and am returning to a factory system. This necessitated some refurbishment of the factory pieces I removed from the car initially which I now am finished with.

When looking at the stock pieces I realized that I was going to have to make some other "adjustments", specifically with regards to the alternator set up. When I built the engine and assembled the car, I made mounts for the GM pump and modern alternator which was all fine and aligned, however I had the alternator using the front groove in the pulley on the dampener, which is normally occupied by the PS system. So returning to a factory PS system I then had to figure out how to get the alternator to work off the rear groove and return to the original style water pump pulley. Because I am running Edelbrock heads, they do not provide enough clearance to put the alternator in the normal position. Subsequently, I had to rotate the alternator outward toward the passenger inner fender and then make a new tension rod. I've got it sorted out now and while it is not optimum in terms of positioning, it does work and actually puts the alternator connections out past the head where they are easily accessible.

I thought about getting a new Power master or similar retro high amp alternator but just could not justify spending ~$200 for something I already had. I will use this system until I have a reason not to.

Here are pictures of the before, after and the new tension rod I made.

Working on getting the PS system and alternator sorted out, I was able to get the factory PS system back in and should be getting the alternator back in soon.

You lost me. It appears you moved the alt. out, closer to fender. Why? I thought you needed to move it to a different pulley groove, forward or back...

Yes I moved it out closer to the fender. I had to do this because I needed to run it off the inside groove (one closest to the engine) which meant that I had to move the alternator towards the head. That alternator is fatter than the old school type and is fattest in the center of the the alternator.

In stock configuration, the alternator runs off the inside groove and the PS pump runs off the outside groove.
