FlowKooler Hi Flow water pumps cool BETTER THAN OEM

Whether it is in stop and go traffic, a slow moving parade, in line at a car show, off road on the trails or hauling a heavy load up a grade all cars face reduced airflow through the radiator at slower speeds.  FlowKooler hi flow water pumps push twice the coolant through the system at these lower speeds and help the engine transfer the heat.  The result is engine temperature reductions of up to thirty degrees, increase system pressure in the engine block which reduces ping and improved flow efficiency which means more horsepower. 

The Benefit of Hi Flow Rates

Most engines keep cool at highway speed.  It makes sense; the engine is turning at higher rpms the waterpump is spinning rapidly and sending coolant through the radiator.  The radiator has good airflow at highway speed.  Of course engines stay cool.  However, at low speed, it is a different story; engines tend to heat up when you face limited airflow, trapped airflow and slow moving coolant.  These condition exist in stop-and-go traffic, at car shows, rock crawling or offroad or in any vehicle under a load.rpm.

For the last fifteen year FlowKooler has focused on increasing the flow rates at lower rpms to resolve low speed overheating.  At idle our pumps pump more than twice other pumps and we outflow “performance” pumps by 20%.  At 3,500 rpms the gallons per minute flow rates level off to standard flow rates. 

Simply put, FlowKooler pumps take the coolant out of the engine and put it in the heat exchanger or radiator to keep you cool.

1. Ending Early Cavitation

Cavitation is the formation of vapor bubbles in a flowing liquid where the pressure of the liquid falls below its vapor pressure. When the vapor bubble that forms rapidly collapses it produces a  destructive shock wave that damages the interior wall of the engine block, other components, causes vibrations and noise and results in a loss of flow efficiency.

FlowKooler patented plate impeller systems reduce the onset of cavitation.

2. Eliminate Hot SpOts and Steam PoCkets 

Engine blocks machined with limited or no cooling jacket can result in steam pockets and hot spots.  This design is great for getting more bore out of your engine but notorious for overheating.  At idle the creation of a hot spot at the top of the cylinder may be enough to cause pre-ignition. At the extreme steam pockets can lead to detonation (hot spots in the cylinder wall); detonation leads to broken parts. At high rpm the coolant moves through the block fast enough to prevent any steam pockets from forming.

FlowKooler pumps suppress engine hot spots and steam pockets by sending more coolant through the system at low speed and simultaneously raise engine block pressure 22% to prevent their formation. 

3. Stop the Knock

Knock, detonation or ping…call it what you want - it is a problem.  Ping heard when the engine is shut off may be the result of pre-ignition.  Pre-ignition results from the air/fuel mixture igniting in the cylinder before the spark plug fires from an ignition source other than the spark.  Hot spots can damage to the point they actual burn holes right through the top of pistons.  Causes include:  

• Carbon deposits form a heat barrier
• An overheated spark plug
• A sharp edge in the combustion chamber or on top of a piston
• A sharp edges on valves
• A lean fuel mixture
• Low coolant level
• Slipping fan clutch
• Failed electric cooling fan

Flowkooler hi flow pumps help reduce engine temperatures and stop the after run or pinging characteristic of a pre-ignition condition.

Knock can also occur when the combustion of in the cylinder starts off correctly with spark plug ignition but one or more pockets of air/fuel mixture explode outside the envelope of the normal combustion front ignition.  It will cause the peak of the combustion process to occur outside of the optimum moment and results in a characteristic metallic "pinging" sound.  The other consequence is an increases in cylinder pressure which can be harmless or destructive to rings piston or bearings.

4. Gain Horsepower

A poorly designed water pump casting and impeller can result in wasted horsepower.  FlowKooler pumps are designed to move water more efficiently from the radiator to the block to keep you cool. 

But Doesn't the coolant have to have more time in the radiator to cool?

No.

In a closed loop heating system if you keep the fluid in the heat echanger your also keeping it in the block longer. Sending hot coolant from your source (engine) through the heat exchanger (radiator) to the sink (air) will transfer heat as long as there is a temperature difference between the source and sink. You have a far better chance of keeping your cool with a greater flow rate through your heat exchanger than gathering heat in your engine block.
