  • Steering: EPAS on Buttercup

    Besides working on the front disc brakes, I've been doing some shade tree engineering on Buttercup's steering.

    The first two pix are of the column with the Saturn upper part attached.

    Whatdya think? Am I crazy or what!

    Jerry is leading edge (as usual). Although it has been used for a few years in new cars, electric power steering is starting to happen for hot rods. Relatively simple, no plumbing, no pump, no engine load. There are new units available just for rods and you can always adapt an OE unit.

    Nicely done, Jerry!

          Are you tying that to the original box or another R&P setup? And what did it come from? Inquiring mind need to know.

          As usual, nice and creative work, Bob

            Original steering box.
            Donor parts from a 2002-7 Saturn Vue (also Equanox).
            Also you have to go to EBAY and get a controller/potentiometer from a guy in Portugal.
            I got the power unit (lower half of the steering column) from a You-Pull-it for $55.
            The next day I realised I also needed the upper half. That cost me another $45.
            If I had gotten it all at the same time it would probably have been $55 for everything. Live and learn.
            The controller/potentiometer was about $75 including shipping from Portugal.

              Very interesting Jerry. I saw that done on TV on Phantom Works on an Avanti. It seemed to work great. They've been doing it for years on ATV's with great success so why not on cars.

                I tracked down the control box and while finding it I see the prices on the used Saturn EPAS units. Your's was still a reasonable deal. I'm not sure how you find what you find but kudos to you for finding and posting same. "Did I use find enough in the sentence?"

                This one stays in the file. Thx, Bob

                  Interesting idea, but I still don't see the need for power steering or brakes in these cars..!?
                  Though I do have four wheel disc brakes on both my 54 wagons, neither have power assisted brakes and they work great. Just pick the right master cylinder piston size. The Stude OEM pedal lengths (both upper and lower lengths) are already very good for this application.

                    ha ha Jerry you surprised me on this one! your earlier post on the 'surprise on the other side of the firewall' had me figuring you placed the 'speeder upper/slower downer' gizmo you posted about a few years back. I was thinking about the aftermarket eps units but the price was scary...kudos to ya for going oem. Not that it matters to you at this point, but there was a thought provoking article in Car and Driver a few months back about the different methods the OEM have created eps systems. thumbs up on this creation, so exciting!cheers Junior

                          A vendor at the recent Portland, OR, swap meet was selling similar, complete set ups (I'm not sure of the OE steering column he used or where he got the controller/potentiometer). I played with his set up some. One thing that is super neat is that you can dial in the amount of assist the EPAS provides...and you don't have to leave it alone if you dash mount the pot. You can dial in a lot of assist when you parallel park, and dial most out when you are on the freeway (or track).

                              That's one reason I'm doing it. Who needs power assist over 15 miles per hour.
                              Now I'm starting to sound like another guy on this forum that thinks anyone that wants more that 175 HP must be crazy. Why would anyone need a car that would run more than 60 MPH. <G>
