I guess alot of people are starting to do this in the auto world. Miata guys love it, and mr2 spyders are getting there. Im pulling a motor out this weekend and ill pull the rack out and see if its possible with ours.

any other thoughts or ideas? Might be a cheap alternative to the Manual rack for 1g guys and a good option for 2g guys.

Nope.

Bump steer is a result of steering geometry which is unaltered during a "de-power". You might feel more bumps, but it won't actually be bump steer.

Read this. :cool:

I'm sure it will increase it.

Drive a Lotus Elise... hitting road reflectors wrenches the wheel from your hands lol.

Honestly it isn't that big of a deal unless you are a total tard.

My friend who has a mr2 spyder did this and he's big into autox and he was telling me that in a turn he can feel when the tires are starting to give so he can steer back into the turn, in other words he loves it lol

My bad, I forgot it's a private forum.
Here ya go:

A few pictures of my newest modification to my Talon.

The correct way to remove power steering from a car besides replacement with a manual rack. This is known as a de-powered power steering rack.... Enjoy.

Looks normal enough, right?

What's this? Are these fabricated plugs? Why, yes they are.

See anything missing in this picture?

Oh yeah, that's right. These are supposed to be there....

"What is this I'm looking at", you ask?

When you remove the belt that drives the power steering pump, you are removing the "assist" to the system. Therefore, the pump is no longer creating the pressure needed to assist with the steering direction. Aside from common belief, the resistence you feel after removing the belt is actually the fluid being forcefully redirected through the lines and partially reverse bias towards the pump. So what has been believed as "removing power steering" is a matter of looping the pressure and return lines together, creating a closed fluid circuit. The "feel" isn't as stiff as before the "removal" and is tolerable by some.

These pictures are of a "de-powered" steering rack. I prefer this method as opposed to replacing the rack with a "unicorn" manual rack because I still maintain the quicker turn-to-turn ratio which gives a more responsive feel when driving. "Isn't it going to be hard to drive at low speeds"? If you guys can deal with the feel of just the removal of the belt, then, this time, you are in for a treat...

No problem, thank you for posting it up. I actually joined the forum to see if he had anymore info of how it was done, but he only eluded to there being a few more things that were needed other than whats listed by Flyin' Miata. I am seriously considering this as something to do, but since my Talon is my daily, I want to make sure I can do it. Thanks again.

So all you do is plug the stock lines. Then cut off those 2 things that run fluid across the rack or what ever and weld them shut? He didn't really explain anything..

I've done it in my Expo van, (same thing). I love it, changing lanes has to be the funnest thing in the world right now. I tore the rack apart and hack sawed the seal off the rack. I also go new inner and outer tie rods and boots. I LOVE it....until i got my dui a few days ago

Even my little 120lb girl can drive it because shes the one driving me around now, she has trouble doing 90* turns and in parking lots. overall road feel is 1000x better. I always thought that the stock power steering was way to sensitive. It took me about 2 days, and an alignment later. I would put it at 7 on a one to ten, ten being the hardest.
