Generates 1000 to 1800psi to the calipers and fits a 1.125\" bore size master cylinder. The Hydropower® is powered by hydraulic pressure from the power steering pump. It requires 'no vacuum'. This has several advantages. No external vacuum pump required on low vacuum high performance motors. No 'small bore' master required. Firewall and valve cover clearance is increased. Frame mounted clearance is increased. Frame mounted Hydropowers® are the same width as a master cylinder, giving additional exhaust clearance.\u003c\/p\u003e\n\n\u003cp\u003eThe Hydropower® can be fitted any where a vacuum booster will fit. It can use stainless braided hoses or rubber type and brackets are available for most applications. The Hydropower® uses fluid pressure from the existing power steering pump. The average power steering pump puts out from 800psi to 1400psi. The Hydropower® uses this pressure that is always circulating through it, to convert to pressure to apply against the master cylinder.\u003c\/p\u003e\n\n\u003cp\u003eThe output of the Hydropower® is affected by three factors.\u003c\/p\u003e\n\n\u003col\u003e\n\t\u003cli\u003eThe pedal ratio. We prefer that the pedal ratio be between 5:1 to 6:1.\u003c\/li\u003e\n\t\u003cli\u003ePressure output from the pump.\u003c\/li\u003e\n\t\u003cli\u003eMaster cylinder bore diameter.\u003c\/li\u003e\n\u003c\/ol\u003e\n\n\u003cp\u003eThese are factors necessary to design the system that will work for a given application. It is imperative that the system be clean. Any residual metallic sediment laying in an old pump or steering box, will be floated up and through the system when the fluid comes through on start up. If any of this sediment lodges in the relief valve of the pump, there will be no pressure from the pump. This will result in hard steering and no power brakes. A filter or a new system is required to maintain any warranty.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eKit includes:\u003c\/strong\u003e\u003c\/p\u003e\n\n\u003cul\u003e\n\t\u003cli\u003eHydropower brake booster\u003c\/li\u003e\n\t\u003cli\u003eMaster cylinder, 1.00\" bore\u003c\/li\u003e\n\t\u003cli\u003eProportioning valve, bracket and lines\u003c\/li\u003e\n\t\u003cli\u003eMounting brackets\u003c\/li\u003e\n\t\u003cli\u003eLimited Lifetime Warranty\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003cp\u003eHydraulic hose kits sold separately\u003c\/p\u003e\n\n\u003cp\u003eNote: These are remanufactured  Hydropower® units.
