That's the battle I fight every time I am in the paddock. Good news is you dont notice it while on track and I have never had a missed lap due to the crappy tendency of the OEM lines/rack/res to vomit fluid!
Might go to an electric PS pump eventually thinking being independent from the driveline may make it more reliable/tunable so overpressurizing doesnt cause leaks.

What steering wheel and disconnect are you using again? Someone stole my 15 year old setup out of my car sometime and need a replacement.....
I've driven 1/2 a lap w/o Power Steering, and I just don't see how you do it!
I'm considering a switch to an MR2 pump, supposedly pressure adjustable. OR, a Prius or similar electric column. Prius columns are cheap, under $200. Add the other parts needed, and I bet total under $400 (not counting fabrication time). I wish someone that's done that conversion would talk about the level of "boost" it has, I want like 50% of BMW OEM.
Steering wheel is an OMP WRC.
Quick release is the Rogue Engineering , https://www.rogueengineering.com/Rog...Hub_p_118.html
I've had no issues with it.
I also have a cheap e-bay 1" spacer.
There is a rebuilt electric PS pump for sale in the track section by the Mcoupe racer........
I was thinking about it but need to focus on more important items first....
Sold! (Not me)
Volvo Electric power steering conversion (Full write up) | Page 4 | Ford Mustang Forums (corral.net)
this thread in mustang land got an interesting update. basically pressure is adjusted via a can bus signal. an theres 2 kits forsale one with a gps sensor and one with a knob.
Well that's cool. I had considered the Volvo pump.
Having an rpm knob for ~$50 would be cool.
The steering rack has a min volume and pressure, so there would be a limit to the min rpm.
How am I just finding out about these? Power Pole connectors. Easy to assembly, can configure and reconfigure into as many I/O as needed.
McMaster Carr also has them.

Starting to do research on a Prius electric steering column. What I've found.
- In fail safe, the Prius column assumes a speed of 43 mph.
- Various random comments from users about steering assist amount and road feel. Can't find any concrete before/after comments.
- It has no return-to-center function, return to center is completely dependent on caster, etc.
- It does require the control unit to be connected to the motor.
- Total weight is ~18lbs.
- I'll have to find a quick-release steering hub for a Prius.
Details matter.
Don't dismiss the Chevy Equinox/Saturn Vue electric steering columns. That vendor from the Mustang thread above has systems for controlling them as well.

this is what wierds me out the most about the column mounted assist. that and it basically acts as a third hand on the wheel. working correctly when letting the wheel slide through your hands to catch the rear dosnt seem to be a discussion ive found at all.. seems most people running these are more hot rods then canyon/track cars.
i did find some rather negative complaints about the volvo setup i think on grassroots forum. i think all that predates the control box dude man is selling now. again related to a loose car not hard steering inputs. sounds rather miserable to have the steering tighten up when you expect it to be its lightest.
So if I lift the car and start it, turn the steering wheel to the left and let go, nothing happens. The wheels don't return to center.
Does hydraulic steering really provide an RTC function?
Return to center is a function of caster.
Whatever power steering you utilize may or may not provide some resistance in returning to center as the
force is coming from the front wheels and not the steering wheel.
it is, however ill say from experience loosing a power steering belt doing donuts is a bit of a code brown moment. not as bad as loosing a swaybar endlink/mount but close.
im totally confused by this electric power steering without trying it. there really dosnt seem to be any confidence inspiring testimonials outside of "my hod rod can pull into a parking spot" the more ive read the more confused i am.
Yea, I'm with ya, I want to see a review by someone who isn't trying to sell something and has more than 1 day on track. Vorschlag put an aftermarket kit in a customers car, but no comments from them on how it worked on-track, and I thought BW put a Prius unit in a project car.
So the ZF rack in my ATS-V was great. Nice feel, plenty of feedback.
The same ZF rack in my M4 felt artificial and provided no feedback.
I guess we get into programming and all that. Too much for a track car for me.
Nothing fun to report.
New springs and ride height. I'm now at 850f/1008r so I could get the ride height down a bit. I may regret these high rates.
Which means alignment time.

I'm still getting noticeable power loss once the engine gets up to operating temperatures. Noticeable, as in 7-8mph top speed drop at the end of the straight. Engine doesn't miss, it just gets very lethargic. On a hot day, it's bad. Logging AFRs with a wide band and they drop from 12.3ish WOT to 10.9ish WOT once engine is up to temp. I've checked the basic stuff, IAT sensor is ok. Just put in fresh injectors. If that doesn't fix it, I guess Link ECU here we come. Can't log or see crap with an OBD1 ECU.
FWIW It may just be pulling timing.
The last 3 engines I've done for myself 11.7 to 11.2 CR have experienced knock when they get hot on 93 pump.
The slowdown from start of first session to final laps is pretty significant. On the dyno it's around 30-35 hp. The DME pulls way more timing than it needs to prevent knock.
I've resorted to spiking the fuel with 100 octane.
At 11.2 I run a 50/50 mix (about 96 octane). Car pulls no timing and is consistent throughout a session. Makes very good power too.
Log your actual timing to see if that's the case.
Thanks for the ideas pshooter! Early in finding the issue, I tried 5 gals of 100 in a near empty tank, and didn't notice any improvement. I have a better handle on when and how the power loss occurs, so I'll try again at the next event.
OBD1 .... so unfortunately can't log timing.
I have not ruled out it's something in the tune. My tuner has spent time with me on the phone coming up with ideas, but so far all have been a dead-end.
I'd love to be able to download the tune and view it, I guess tunerpro is an option?
Current tune is by Kassel Performance, York PA.
Recent lap/session videos???
Sure!

Damnit. That looks fun! Shenandoah looks like it would be a blast in the e36. Is the wheel straight ever?
Car looks seriously quick. Maybe I need to yank the dash out of mine too
VERY nice driving.
Yep, Shenandoah is a fun fun track for the E36! The car is really hooking up this year, so what do I do? Change spring rates of course. lol.
I have a rule, if I remove it from the car, I don't put it back unless it makes me faster or safer.
Thanks, it's a fun setup, so it's easy to drive well.
