I posted this in the grandstand, but figured you guys would be interested too.

I'm doing the AGR power steering setup on 1728. Got the rack and pump from AGR and the pulley, mounting bracket, bracket mounting kit from Jones Racing.
The pump is a TC series 1100psi low flow unit (w/ reservoir)
The pulley is 4.25"

I ended up not being able to use the bracket from jones racing because it puts the pump reservoir right where the steering shaft is , so I had to fab up my own mounting bracket.

MY bracket I'm planning on trimming some material off to make it a bit lighter. If there's any interest in these, I'd be willing to consider having a batch made at a CNC shop, but I couldn't justify the programming time for just me. If anyone is interested, the mounting plate is 1/2" thick bar stock 4" x 6" and the spacers are 3.5" long.

The pump mounted in place.

First layout with the hoses. The pressure line ended up too long, so I'll have to cut some off and have a new end put on.

i swapped to the AGR rack and pump a year or so ago. it is slightly better than the autozone rack i had before (less shaft free play), but mostly, i cant tell the difference. there is more freeplay now than when i installed it.

i initially had a problem with AGR sending me the wrong part and suggesting i pay to fix the problem, but in the end they got it right.

nice looking install leonard!

I was pretty happy how the bracket turned out considering I don't really have the proper tools to do fabrication work. I did all of my work with a jigsaw, a hand drill, a file and some sandpaper.

Had to laugh - when I was looking hard at the pictures I could not tell why the hose went into the top of the little plate.

Then I realize the hose when under the plate but in the photo it was perfectly lined up with the hood pin

Looks good - still driving in manual mode. Hope to start my first season this year.

Well, I finally got to test drive the power steering setup today after some 'technical difficulties'.

The first time I fired it up after filling the system with fluid, the main rack seal blew out. The driver side boot filled with fluid and blew off baptizing me with fluid while I was leaning over the reservoir wondering why the level was dropping... I called AGR that night and they asked that I send both the rack and pump back. They wanted to inspect and rebuild the rack to verify that all was well with the pump (they suspected either a bad rack or something internally wrong with the pump causing an over pressure situation). The end conclusion was that it was a bad seal in the rack. While they had the pump, they modified it to produce 1000psi instead of 1100psi. All in all, I'm satisfied with how they handled the situation. It always sucks to get a defective part, but it happens to everyone from time to time. AGR didn't give me any hassles with making the situation right. The only complaint I have is that it took around 3 weeks for me to get everything back from them.

It's NIGHT AND DAY from the de-powered manual rack. I took a rough guess on the front alignment and it's got a 'bit' of toe out (enough to just barely see, so I guess that's more than a bit) so it feels quite twitchy at the moment. At this point I'm totaly satisfied with the steering effort although I can see myself eventually wanting a little less assist than I have now. I tend to toss the car around a bit and will need to slow down my input speed.

For those that are curious:

AGR PN: 732581 15:1 Rack w/ ure-Steel Bushing
AGR PN: 804412 Aluminum TC pump low flow 1100 psi (modified down to 1000psi)

Rack AN fitting adapters:
AGR PN: 910800

I got my pulley from . Talk to Chuck Jones and he'll tell you exactly what size you need for you application (it'll be dependent on the max rpm of your engine so you don't overdrive the pump). Don't call if you're in a hurry... he's got lots of stories. [img]smile.gif[/img]

Bracket & Mounting kit:
I got the one from Jones Racing, but it put the pump right where the MKI steering shaft goes. I fabbed up my own mounting bracket and modified the mounting kit from jones racing to work with it. You could just as well get some hex rod stock and make the mounting kit from that as it's pretty simple. I can post more details if anyone wants them.
