Most builders chasing horsepower focus on the obvious stuff: cam, carburetor, compression.
The mechanical water pump bolted to the front of the engine rarely comes up in that conversation. It should.
A traditional belt-driven water pump is a constant parasite on your crankshaft, and on a performance build every bit of power it consumes is power that never reaches the rear wheels.
Switching to an electric water pump removes that parasite entirely.
What a Mechanical Pump Actually Costs You
A belt-driven water pump is spinning whenever the engine is running, drawing power directly off the crankshaft through the accessory drive.
At high RPM that load increases significantly, the pump is working harder precisely when you want every available horsepower going elsewhere. It's not a small number either.
Our PROFORM electric water pumps can free up 15 to 20 horsepower compared to a mechanical pump setup, depending on the application.
On a bracket car where you're chasing fractions of a second, or a street machine where you want everything the engine can give, that's a real and measurable gain.
How an Electric Water Pump Works Differently
Instead of pulling power off the crank, an electric water pump runs on a dedicated 12-volt electrical circuit completely independent of the accessory drive.
Our pumps draw only 6 amps at 12 volts — a minimal electrical load that has no meaningful impact on your charging system — while flowing 35 or more gallons per minute through the cooling system.
That flow rate handles V8 engines up to 650 horsepower, covering the vast majority of street and strip builds.
Removing the water pump from the accessory drive also simplifies your belt routing and can free up space at the front of the engine, which matters on builds where header clearance or tight engine bay packaging is already a challenge.
Weight Savings on Top of the Power Gains
A cast iron or even aluminum mechanical water pump with its housing, pulley, and associated hardware adds meaningful weight to the front of the engine. Our SBC and Ford electric water pumps come in around 6 lbs.
Our BBC unit is approximately 7 lbs. That's the entire pump, ready to install. For a car being built with weight distribution in mind, removing a heavy mechanical pump and replacing it with a compact electric unit makes a difference you can measure on the scales.
Built for Street and Strip Use
Our electric water pumps are designed to handle both environments without compromise.
The heavy-duty brush motor runs continuously at the flow rate your engine needs, and each pump is built with a solid one-piece base construction that reduces the chance of leakage. A common weak point on pumps that use multi-piece housings.
Life expectancy is rated at 2,500 or more hours, which translates to years of real-world use on a street-driven car or a full race season on a dedicated track vehicle.
A 1-inch NPT inlet adapter for 1¾ inch slip hose is included with every pump, so you're not hunting for fittings to complete the installation.
Application and Finish Options
Our electric water pump lineup covers the most common performance V8 applications:
Chevrolet® small block Gen I, Chevrolet big block, and Ford 289-302 engines. Each application is available in multiple finishes so the pump integrates cleanly with the rest of your engine bay.
SBC and Ford pumps come in blue, black, red, polished, and chrome. The BBC units are available in blue, black, and red.
If you're building a show-quality engine bay, the polished and chrome options hold up visually the same way our valve covers and alternators do. If the car is a dedicated race vehicle where appearance takes a back seat, black or the colored finishes work just as well under the hood.
One Thing Worth Knowing Before You Install
An electric water pump needs a switched 12-volt power source and needs to be wired so it runs whenever the engine is running.
Unlike a mechanical pump that operates automatically, the electric unit depends on your wiring to keep coolant flowing. On a street car this typically means wiring through your ignition switch.
On a race car it means making sure the pump circuit is on your standard pre-race checklist. It's a simple installation consideration, but worth planning before the pump goes in rather than after.
Every Pump is 100% New
Like everything in the PROFORM lineup, our electric water pumps are built from 100% new components. Not remanufactured, not rebuilt cores. A pump going into a fresh engine build or a car you've put real time into deserves components with no prior wear history.
