Oh yah. 'Do over' is becoming the theme in my garage. Little things like the engine, transmission, and rear axle/suspension are next.

Look forward to seeing you and Payback next month for sure!

That is why we sell the LEE Boxes! Tom has been designing and building power steering since before most of us ever herd of power steering, he is the one that builds steering boxes for Tony Stewart, among others, ALMS cars. Ford / GM sends stuff to him to evaluate. i am sure he has forgoten more than we will ever know.

So perhaps, "Do Over" is an option---although I did really like "Setback"---lol. That was a good one. Have you wife name it---or not.

Dude, the dented headers would really bug me, especially because the driver and passenger sides would look noticeably different. Rather than spend the money having an exhaust shop cut and modify several of the primaries, might a suggest a cheaper alternative:

Exhibit A:


As you will see from the picture above, it has already been made to match your driver's side header. If you are interested I am willing to negotiate a reasonable price.

I asked Lee to rebuild to match the new box and to rebuild it so that it would take some occasional racing. So it's slightly lower pressure at low RPM which causes a little more effort in steering, but hopefully that saves me from having too much pressure at high RPM. I don't get over 5800RPMs so I'm not stressing the pump too much like some folks might.

I've talked with people that have had good luck with AGR and talked with people that had the same experience I did, so I think it's a bit random. Honestly, I don't think there should be that much randomness for that kind of money. When I spoke with Lee, they actually had a good explanation for why that randomness might occur with other vendors and it's why they completely disassemble and rebuild each unit they get from GM. Who knows, maybe a 4th try with AGR would've worked out, but it's such a pain in the arse for me to remove that box so I just wanted to try something new that might eliminate 'chance'. Each person I talked to that used Lee was very happy, so I gave them a shot. Now, if the Lee box blows out at RTTC, I'm going yank the whole steering system and just tie 2 ropes to the steering knuckles and go that route.

Thanks for the reply Chris. Since I have the AGR 12:1 box I think I'll try matching it with their upgraded pump. We'll know soon enough how it works!

Personally, I like Fumigator for your car name.

I am a bit confused as to the need to have the pump"re-valved" to "match" the box. All of the effort valving is contained in the box, the only thing in the pump is the high-pressure bypass and any lowering of that value can cause a lack of assist when assist is most needed.

Or am I not understanding things here?

Bill -- Don't try to use a Chevy pump on a Ford rack.....

That's what's being changed -- the orifice in the pump on a Chevy is too large for the Ford rack...

Not sure what is what on these boxes and pumps being discussed in this thread - but obviously there is a mis-match that has to be "adjusted".

you can effect the "FEEL" of the steering by playing with the flow valve. if the flow is too hight the steering will be really twitchy.
if you restrict the flow you can firm up the feel of the steering. it is especially easy to do with the TC serice pumps that come on the LS motors as the valve is rigth on top and easy to access and lots of companies have different orifice sized valves.

Hmmm... but "twitchiness" should be a function of the torsion valve, yes? Any unused volume should be dumped by the pressure relief valve...

I am still confused I think...

great, now I'm confused about being confused!
