De powering via pump.....

Post by Choochoochoo » Sun Apr 03, 2016 6:39 pm

Eventually I plan to just de power the rack, but I've got a spare pump that seems to be seized hanging around and was wondering if I could just take the pump part out of the actual pump to eliminate the power steering for now..... Like I said, eventually I'd like to just de power the rack, but I don't have the $ for another rack right now, and I can't afford to have my car down, it's my dd......

Why are you wanting to depower the rack?

Don't need it, less drag on the engine without it.... I'm going for the simplest setup possible.. I just drive around town for the most part, but I ocassionally do some canyon carving too.. I think it's mainly that I just don't really feel that I need it...

Ill put it to you like this.

Ford used it on their rally cars. It WILL increase steering effort when "canyon carving". What does this mean? You will engage larger muscle groups which will remove some of your steering accuracy as you will disengage some of your smaller fine motor control muscle groups.

How much power is deleting powersteering worth? Maybe 5hp. Not worth it unless you are drag racing it, maybe. But then if you are drag racing you are using a poor platform to drag race with...


In any case there should be a write up of how to do it if you search or maybe on the merkur tech pages. Failing that you could always buy a manual rack from europe.

Keep the power steering, a depowered rack sucks if you drive on a regular basis.

Choochoochoo,

Yes you can de power the rack by removing the guts from the pump. Just keep fluid in it

having been there done that, i agree with others, it is not a fun time. maybe if you could find the unobtanium manual steering rack with a more friendly ratio, but with the stocker it just is not fun.

I depowered my rack and have been driving this way for 5-6 months now. I'm putting it back in as soon as i find the time. The car is daily driven plus i autox it and i notice that without PS, its a ton more effort for the 3-5HP gain.

Yeah I de powered my first white car.
I got a 4:1 manual rack from Europe.
That car was a daily around town & too heavy to steer + the extra turns with the 4:1 made it feel like I was driving an old truck.
