Thestock oil pump is a great piece for up to 9,000 rpm in drag racing and 8,000 rpm in endurance racing. Past that, there can be cavitation issues and oil pressure drops as temperatures rise. Our ported pump increases flow by 25% and will allow continuous use above 9,000 rpm. The pump has been tested as high as 12,000 rpm with great success. We start with a brand new OEM oil pump from Honda, disassemble, port and smooth oil passages to increase flow. The pumps are then cleaned, oiled, reassembled and repackaged. This part is cheap insurance to protect your multi-thousand dollar investment.

Add a 4P Rooster Ring to help with the install! Simply slide the Rooster Ring onto the crank snout, then slide the oil pump over it into place. It perfectly centers the pump, expands the lip seal and keeps it in the proper orientation helping it slide perfectly onto the crank. No more fighting it. Once you use it, you'll praise how this simple tool can make such a big difference.

The stock K-Series oil pump is a great piece for up to 8,000 rpm. Past that, there can be cavitation issues and oil pressure drops as temperatures rise. The 4P ported pump increases flow by 25% and will allow continuous use above 9,000 rpm. The pump has been tested to 12,000 rpm with great success. The 4P Pump is designed to be used on all K24 and K20 engines (including the K20Z3). This part is cheap insurance to protect your multi-thousand dollar investment.

This pump has some advantages over the S2K pumps that are commonly used. The pickup is further forward, and lower in the pan, and it frees up an additional 1-2hp. This is the chosen pump for all of our racing engines for many of these reasons.

The stock oil pump is one of the weak links in your H22 engine. These pumps cavitate and lose pressure at high rpm and especially when oil temperatures rise in endurance applications. Our ported pump increases flow and eliminates cavitation to resolve these shortcomings. We start with a brand new OEM oil pump from Honda, disassemble, port and smooth oil passages to increase flow. The pumps are then cleaned, oiled, reassembled and repackaged. This part is cheap insurance to protect your multi-thousand dollar investment.

There are three main types of heat pumps connected by ducts: air-to-air, water source, and geothermal. They collect heat from the air, water, or ground outside your home and concentrate it for use inside.

Today's heat pump can reduce your electricity use for heating by approximately 65% compared to electric resistance heating such as furnaces and baseboard heaters. High-efficiency heat pumps also dehumidify better than standard central air conditioners, resulting in less energy usage and more cooling comfort in summer months.

Air-source heat pumps have been used for many years in nearly all parts of the United States, but they've not always been used in areas that experienced extended periods of subfreezing temperatures. However, air-source heat pump technology has advanced so that it now offers a legitimate space heating alternative in colder regions.

In addition, a special type of air-source heat pump called a "reverse cycle chiller" generates hot and cold water rather than air, allowing it to be used with radiant floor heating systems in heating mode.

Geothermal (or ground source) heat pumps have some major advantages. They can reduce energy use by 70%-80%, control humidity, are sturdy and reliable, and fit in a wide variety of homes. Whether a geothermal heat pump is appropriate for you will depend on the size of your lot, the subsoil, and the landscape.

They are different from compression heat pumps that are driven by mechanical energy and can be driven with a wide variety of heat sources such as combustion of natural gas, steam solar-heated water, air or geothermal-heated water.

Unlike standard compressors that can only operate at full capacity, two-speed compressors allow heat pumps to operate close to the heating or cooling capacity needed at any particular outdoor temperature, saving energy by reducing on/off operation and compressor wear.

Two-speed heat pumps also work well with zone control systems. Zone control systems, often found in larger homes, use automatic dampers to allow the heat pump to keep different rooms at different temperatures.

The variable-speed controls for these fans attempt to keep the air moving at a comfortable velocity, minimizing cool drafts and maximizing electrical savings. It also minimizes the noise from the blower running at full speed.

Another advance in heat pump technology is the scroll compressor, which consists of two spiral-shaped scrolls. One remains stationary, while the other orbits around it, compressing the refrigerant by forcing it into increasingly smaller areas.

Compared to the typical piston compressors, scroll compressors have a longer operating life and are quieter. According to some reports, heat pumps with scroll compressors provide 10 to 15F (5.6 to 8.3C) warmer air when in the heating mode, compared to existing heat pumps with piston compressors.

Although most heat pumps use electric resistance heaters as a backup for cold weather, heat pumps can also be equipped in combination with a gas furnace, sometimes referred to as a dual-fuel or hybrid system, to supplement the heat pump. This helps solve the problem of the heat pump operating less efficiently at low temperatures and reduces its use of electricity.

In comparison with a combustion fuel-fired furnace or standard heat pump alone, this type of system can also be more economical. Actual energy savings depend on the relative costs of the combustion fuel relative to electricity.

Even with the impressive performance of heat pumps, the U.S. Department of Energy (DOE) is still researching ways to make heat pumps more affordable and efficient. To that end, DOE launched the Residential Cold Climate Heat Pump Technology Challenge in 2021 to accelerate deployment of cold climate heat pump technologies.

Aiming at the problem that the flow rate of the two cavities of the differential cylinder does not match and it is not easy to achieve pump control, the team proposed the asymmetrical distribution principle of the axial piston pump with three ports, which can compensate for the flow difference between the two cavities of the differential cylinder without auxiliary components. Based on this principle, a new type of valve plate structure is designed by using the residual compression method. The pump performance is analyzed by PumpLinx simulation and experiment; the influence of the transition zone structure on the pressure and flow characteristics of the piston pump is researched. The basic characteristics of the pump such as pressure, flow, and noise under different working conditions were tested on the experimental platform, and the rationality of the new structure was verified. The new flow distribution scheme can not only compensate the flow difference of the differential cylinder, but also output two different pressures, which realizes the ideal effect of the hydraulic pump directly controlling the differential cylinder. The research work lays a theoretical foundation for the realization of the pump-controlled volumetric direct drive system.
