FlowKooler Hi-Flow mechanical water pumps resolve low-speed heating problems by doubling flow rates at low rpm and idle. CNC precision-machined impellers feature larger diameters, increased vane count, tighter clearances, shrouding, and porting. These unique design features help drop engine temperatures by up to 30 degrees, increase the block pressure to prevent hot spots on cylinder walls, and stop the formation of steam pockets in the block, all while delaying the onset of cavitation at higher rpm. FlowKooler Hi-Flow mechanical water pump impellers are protected from electrolysis and corrosion with a military-grade Type II Class II anodized surface coating.

Tests prove that many standard engine-driven water pumps produce severe drag at high-rpm, absorbing as much as 15 to 20 hp. Here's the solution for that issue. Moroso electric water pump drive kits come complete with a 12 V electric motor, all drive pulleys, belts, fasteners, and a toggle switch. They fit a wide range of makes and models as far back as the mid-1950s, and the drive kits are ideal for drag racing applications.

• Milodon’s exclusive high efficiency impeller design is installed into new GMB castings using heavy-duty bearings and large-diameter shafts. It is the impeller that makes the pump work so much better than a standard, stock design water pump. • Milodon water pumps are available in high-volume (steel or aluminum) and standard-volume versions Pumps are direct factory replacements with OEM hose connections and bosses. • These high-volume pumps have a balanced distribution design (equal flow to both sides of the engine block) and a high-efficiency impeller that increases coolant flow up to 30 percent over stock. • These features increase coolant pressure in the block to prevent hot spots and air pockets and improve coolant flow in the radiator. • A high-flow thermostat is recommended when using a high-volume pump.

Get maximum cooling for the street or track. Edelbrock Victor Series high-volume water pumps are designed for maximum flow and equal coolant distribution in street cars, race cars, tow vehicles, and motor homes. The aluminum pumps have CNC-machined housings with special one-way internal passages that flow more coolant at higher velocities, even at low engine speeds. The CNC-machined impellers are larger than other impellers and have curved vanes that produce greater flow with less cavitation. Other features include heavy-duty roller bearing assemblies built to withstand higher torsional loads, billet steel hubs, leakproof seals, and gaskets. Most Victor Series pumps are available in your choice of satin, black, and polished finishes, or EnduraShine.
