Those that I know that have power steering run a pump off a belt on their motor. I have seen some homemade brackets to some well machined ones. Depends on what you want to do and pay for. The Wild Kids |

There are basically 2 setups you can use. The first and simplest is the Torque generater. It is mounted between the steering rod and the Rack and is the power assist. The pump mounts to the motor or frame and is driven off of a pully bolted to the crank in front of the alternater pully. (BTW I have a brand new pully I will not be using if your interested). The down side of the Torque generater is all of the load is on the rack. The second and better system is the Servo/Ram. The servo mounts in the same place the Torque generater would go. The ram is attached to the rack and the frame. This system works kinda like a hydraulic log splitter. But instead of useing a handel and a valve body to control the fluid flow to move the ram back and forth the servo does that for you. As you turn the wheel the servo directs the flwo to the corresponding end of the ram and pushs on the ram slider. Keep in mind that there is still a mechanical connection to the rack from the steering colume just like if you did not have power sterring. So if you lost a belt etc. You would still have sterring. I bought most of the parts for mine on ebay at a fraction of the cost buying new. A completes system new is $1500.00 I have around $600.00 in mine. |

I had a servo ram system it sucked it is on a chaindrive I sold Jeff Busby he then sold it to Mickey mouse both will tell you . they both have the torque genarator now I have been running a torque gen for 8 years on the same rack .My wife has run one for about 6 or 7 years with a econo rack ain't broke yet and we don't baby them and a chain drive is a hole lot harder on a front end than a conv buggy |

IT was to slow unless you had it wide open it was not power at idle no power mine you can sit next to a tree with motor idleing turn wheel and move the buggy over with your pinky finger turning the wheel .And I said mine sucked I didnot say yours sucked I hope you like yours I sho do like mine torque gen $328.57 saco rack $350 pump off a hundia $25 lines $50 around $753 bucks sounds good to me |

I think it depends on the pump and ram that are used. A lot of guys are running the servo ram setup on rockcrawlers that rarely rev above 2500 rpm's and turn 40"-50" tires standing still or against rocks. A ram with too large of a bore will be very slow. If you buy a ram buy one specifically made for your application not an off the shelf ram from tractor supply that is made for a log splitter. The torque generator is proven also for forklifts. |

I have had to machine different size pulleys to increase or decrease the pressure at lower rpm's---just another thing to consider. |

rockrockets1, I know you did not say that mine sucked, I was just wondering what was it about yours that you did not like. I have not even used mine yet. Thats why I asked. I had considered that possiable problem at idel. I had purchased a pully and when it came it was only 3" diameter. Just be sure I had enough pump speed at low RPM I went with a 4" pully. I also used a Sweet ram that has a 1 1/4" Diameter piston to help with low speed driving. |

Eric the 4" pully is for the motor. The pully on the pump is 6". The 3" motor pully I had would be a 2:1 ratio. The 4" gives me a 1.5:1 ratio so the pump turns faster. |

At idle but whay about 8800 rpm then that sucker is pumping air bubbles and foam |

My motor will never see 8800 RPM. Even if it did the Pump would only see 5867 RPM and most pumps have a max of 6000 RPM. My cam is only going to allow the motor to turn at max 6000 RPM and the pump would see 4000 RPM. I would think that the average Motor RPM will be around 4000 so the average pump RPM would be at 2667. My recieving canister also has a defoaming baffle so that will help a lot. I think Im covered |

I have a grandam rack and it works great, but it (the pump) needs to be a little faster then idle, and I already have it turning a lot faster (smaller pulley on pump) then it was on the car. Maybe the car had a |

Yes you can turn a pump to fast. I believe tha max is 6K in general before they start to cavitate. As you said Its possiable that your rack needs more volume that the pump is capable of providing. Basically a mismatch. |

Has anyone tried the electric pumps from the newer chevy cobalts? Sounds like a good idea if it works.. |
