Quantum Fuel Systems - High Performance Power Steering
Improve steering feel with MM’s new High Performance Power Steering System. A
common complaint about the Fox chassis Mustangs in high performance driving
situations is the over-assisted stock power steering system. The high assist
level of the stock system makes the steering feel extremely light, and reduces
the usable feedback to the driver. This light feel causes the driver to turn the
steering wheel much more than intended, which leads to a lack of driving
This MM kit greatly improves the steering feel by reducing the amount of power assist. Steering effort is increased just enough to provide good feedback to the driver. The MM kit optimizes the pump’s output pressure, without reducing the output volume, by having a larger pressure regulator shunt path than does the stock pump. Home-brewed efforts to improve steering feel by using larger pulleys or restrictor orifices can cause a sudden loss of steering assist during rapid movements of the steering wheel, a potentially dangerous situation. Because the MM pump maintains the proper output volume, the level of power assist remains constant, regardless of how rapidly the steering wheel is turned.
The pump in this MM kit requires less engine power to operate than the stock power steering pump, freeing up horsepower for quicker acceleration. It can be run at over 7,000 RPM for extended periods of time without overheating the power steering fluid. Install this kit and put an end to the problems caused by the stock pump: Over-assisted and imprecise steering, fluid spewing because of fluid overheating, and that annoying whine! The reduced pressure of this pump also reduces the likelihood of blowing out steering rack seals. Except for the serpentine belt, the MM kit includes everything needed for installation: High-performance pump, a pump mounting bracket designed specifically by MM for the Mustang 5.0 engine, a fluid reservoir, a large fluid cooler, all necessary hardware, and all hoses and fittings. Does not reuse any OEM hoses. The MM kit converts the pump’s inlet and outlet fittings, as well as the steering rack’s inlet and outlet fittings, to easily serviceable AN fittings and hoses.
The level of steering assist can be adjusted to suit personal preferences by changing the outlet restrictors on the pump. This can be done with the addition of the Restrictor Valve kit, part number ST-71.
Note: A belt with a different length is required. Does not fit with air conditioning.
