Does anyone have before & after dynos for the power steering delete?

My Citroen was 2.0 LTL and there is a limit to how steady you can be in a DD, especially if you still have a pulse. Turn to talk to a passenger or sneeze & you can find yourself in the next lane...lol

Not a legal option in a Spec E30.

I figured that was the case in your car.

In time. Z3 rack right?

I have a regular e36 rack in my car and it feels right to me. The stock E30 rack is really slow, you get used to it if it's all you drive but switching back and forth between my cars really highlights the situation.

With the E36 rack in, i don't feel the need to go quicker (Z3)

Some think the Z3 is quick to the point of being twitchy. Stock e36 rack is great IMHO as well as cheaper and easier to find in a boneyard

Crap, I just threw one of those away.

Install E36 rack. BAM! done.

One of the nice things about power steering on the track is that it also reduces
the hit your hands take when you pummel something like a curb-
the shuttle valve doesn't care whether the turn force is coming from the
steering wheels or the rack, it just tries to do what the steering wheel is doing...

interesting. I wouldn't mind reduced power assist. My e30 currently has the p/s deleted and to be honest, it's not hard to turn at all.

I would think there is some form of hydraulic pressure regulator on the market that doesnt carry too high of a weight penalty that can be adapted for your application. change the pump and rack lines to AN fittings and you should be able to get something to work

Hydraulics 101..get a variable output pump. I sold Toyotas when they were made from beer cans and I think they had them then.

Someone should do this mod and report back ;)

Your turning horsepower goes down definitely.

I've thought of a bypass type pressure regulator and of fitting a larger pump pulley. But haven't yet tried to do anything along those lines.

What I'd really like is "dial back" the pump for less assist.

I've heard numbers from 4-6hp, but what I saw on a dyno was more like 1-2hp. Which is on the order of the repeatability/uncertainty in dyno runs. So I'd have say the power advantage is pretty much nothing.

I deleted the power steering on my race car and have run it like that for a long time. But I've recently learned that really isn't a great idea. The lack of power steering increases driver fatigue and means having to move your hands around on the steering wheel for leverage, though deleting PS does increase steering feel. AFAIK, all pro road race cars have some form of power steering. I've put the system back on, but one of the small rack lines is leaking and will have to be changed.

+20-30 bhp.. depends on the width of the belt being removed , wider belt more hp gain.

And if you can't properly maneuver your vehicle at all situations without power steering you are indeed a 10 year old girl.

+1000

I'm a twig and I don't miss ps at all.
