Just curious if you still like the Borgeson conversion after 5 months and if you got all the leaks stopped.  I purchased a '74 coupe last May as a project car for me and my grandson.  It's a no-options car, mostly original.  Seriously considering converting it to power steering so my old arms don't have to work so hard to park it :)  When I discussed Borgeson with the owner of one of our local Corvette shops, he said he had installed a lot of them and a lot of them leaked.  Any feedback you can spare would be most appreciated.

Hmmm, not sure about any Borgeson setups that still use the valve and cylinder.  IMHO, there are two main advantages of going to the Borgeson for C3 owners: 1) you get to get RID of the leaky cylinder and valve, along with two of the four hoses and 2) quicker ratio.  

I know that both Corvette Central and Ecklers offer kits that look like the Borgeson unit, but they're not identified with that brand.  I don't know if they're knock offs and made by someone else or if they just have an agreement with Borgeson.  I got mine on eBay from a reputable seller and it came in a Borgeson box with printed materials from them and their stamp on the parts.  

Out of curiosity, I did a little research.  Borgeson started in 1914 making steering components and that's all they make today.  In the 50s they started on power steering conversions for GM cars and other makes.  In the 60s and 70s it became popular to replace stock GM saginaw boxes with a Borgeson since they're stouter and have the quicker ratio.  But most GM cars with P/S have the boost built right into the box so it was really just a direct bolt in-replacement.  But C2 and C3 Vettes have the system we know all too well that relies on the external valve and cylinder to provide the boost.  I've always wondered why they went that way for the Vette - the Saginaw P/S box was already designed and being used.  Maybe it was space considerations.  But the fatal flaw with that design is the hoses that have to flex every time the car is steered.  It also reduces ground clearance and is susceptible to road debris.  

LOL, you'll have to ask me next summer!  Summer was pretty much over when I got the conversion finished up and I drove the car very little this summer anyway due to COVID (no shows to go to and such).  

I think I've got the leaking resolved, but it's something I'll have to watch.  At least on here I haven't seen a lot of negative feedback about leaking, but the owner of that shop probably has more experience with that.  

In the handful of times I've driven it since the conversion I have an overall positive impression.  The quicker ratio is great but the effort is lighter than I was hoping for so that's a bit of a disappointment.  (Lighter than stock P/S on my '76)  That, coupled with the fact it needs an alignment is making it a bit of a learning curve in driving.  Also the center "dead zone" is reduced greatly from stock so all those things combined can make it a little twitchy at speed.  Borgeson recommends a 4 wheel alignment after install with at least one spec (I think it's camber) changed from stock.  I'm hopeful that once I do that next spring some of that twitchiness will decrease.  (or maybe I'll just get better at driving it).  But as I said in my last post, the best benefit for me was getting rid of the cylinder, valve and hoses that have to flex at every steering input!  So tired of P/S leaks!

Hi Dave, check in Borgeson for a washer kit. It lowers the fluid pressure in the pump. Goes on the pressure end. I used this on my steroids rack and it helped the dirty feeling.

Thanks for the tip - that would make sense to reduce the pressure, thus lowering the boost.  I'll check that out!
