  1. @1969 Mach 1: I am very curious now! I only wish I had a length measurement too so I can compare with my 16:1 box. BTW the saginaw pumps (if thats what you're using) work great at idle, but for me when cruising or going fast the steering is way too light. There are valve kits offered to tune the assist down and eventually I will get to that.


  2. My Mach:

    I just realized that I may not have posted everything on this forum yet oops... Let me know if you want me to PM you some links but I'll summarize here. I am running 6.7 degrees of caster. They based the 16:1 boxes from some Isuzu or Toyota or something and I am sure they weren't setup with more than 7 degrees of caster. There is terrible on-center numbness caused by this bind, which is what causes the car to wander like you have read from other peoples experiences. The bind I speak of is because of the following for those people interested.

    The borgeson, although in line with the steering column like it should be, puts the center link in a lower position than the factory box does. This is because of the box being longer so they mounted it so that it would bolt on which it does. This wouldn't be a problem if the idler arm had a joint at the connection with the center link but its just a pivot point. The hole in the center link for the idler to go through is at a different angle than the idler is set up for from the factory. It works, but the junction is such that smooth movement is only happening with the wheel turned more than about 1/2 turn or so. Once the wheel is turned this much the angle of the idler arm better matches the center link and the steering feel is there/fine. 

     

    1969 Mach: I would love pictures of the new box, as many as possible please! I am wondering if they started with an entirely new case etc. If the problem I speak of above was fixed via design that would sure make a huge difference for how the car drives. I have fantasized some way of creating or modifying an idler arm with some kind of ball joint type thing or just one with correct geometry with a Borgeson...


  3. Just so you know the lost turning radius is significantly more than the drop bracket does with stock P/S. My opinion on this subject is the following:

     

    If the stock system could have a better ratio gear box, that is how I would have done mine (even in hindsight). I have a Borgeson 16:1 and its ok, but a design flaw creates bind between the center link and idler arm at the center of steering. This makes the car not return to center well and creates numbness in terms of steering feel which I hate. I have other posts you can read with more details if you're interested. I have heard the newer 14:1 boxes are a different design but to me that has not been seen/verified. My stock leaky system had better feel and way better return than my Borgeson does. Caster band aids this issue but doesn't fix it contrary to what some say.

     

    For a rack, IMHO its not worth it unless you really spend a lot for something top end like the TCP setup, the RRS setup (my personal favorite) or the like. They all have their drawbacks, either with install, fitment, design etc. 


  4. As someone that has been looking for 164t parts, I am finding much more options for the 157t setup. Either will work, I just wanted to maximize clutch size. Boss 302's ran 164t but that may have been because twin disc setups weren't around yet.

    I'm going aluminum for my flywheel, and my car is mainly street. The 164t in aluminum is still like 7 or 8lbs heavier than the 157t aluminum so I figure it's a decent compromise for a street machine that sees track time. I fell in love driving a friends car with an aluminum flywheel , and since I am planning my toploader swap I figured I might as well. Anyone got a 164t manual block plate lying around?


  5. For the record I have posted why the return to center issue exists if you're wondering. To be honest I hate the steering feel because of this with my borgeson box, and it definitely makes me wonder if an EPAS system with the factory box (+ lots of caster like I have) would work better. I am pretty anti-rack for old mustangs and just wish the borgeson/others were designed with the proper geometry in mind. I have been tossing ideas around in my head for how to modify the idler arm to take into account the change in geometry because I think this would help tremendously...
