The ColdFront Coolant Pump
The AWE Tuning ColdFront Coolant Pump is the final member of the
ColdFront family. Manufactured by the cooling-system wizards at Meziere
Enterprises, who have nearly three decades worth of experience in
engineering and manufacturing performance cooling system components, the
ColdFront Coolant Pump replaces the stock heat exchanger pump -- and
out-performs it to the tune of an impressive 100% gain in flow-rate over
the factory pump. During excessive dynamometer torture testing on our
in house 3.0T, we recorded an additional 8% decrease in intake air
temperatures when the pump was combined with the ColdFront Heat
Exchanger and ColdFront Reservoir. Cool.
Partner products:
While the ColdFront Coolant Pump may be used in conjunction with the
stock heat exchanger, it cannot be used without the ColdFront
Reservoir. Please note, AWE Tuning ColdFront Systems are for racing use only.
- Racing Use Only
Below are graphs of the performance testing done on the ColdFront - System. All tests were performed on the AWE Tuning Mustang MD-500-SE
- AWD dyno using a 6-speed B8 Audi S4 equipped with G.I.A.C. Stage 2
- Performance Pulley Software on 93 octane pump gas in a controlled
- ambient temperature of 90F.
-
- Above is a graph showing the supercharger coolant temperature difference
- of the coolant before entering vs. after exiting the ColdFront™ Heat
- Exchanger. The red line represents the pre heat exchanger coolant temperature. The green
- line represents the post heat exchanger coolant temperature. The top
- graph shows the temperature difference the stock heat exchanger is
- capable of producing, the middle graph shows the temperature difference
- the ColdFront Heat Exchanger is capable of producing, and the third
- graphs show the temperature difference the ColdFront™ Heat Exchanger and
- Reservoir are capable of producing.
- It can be seen that the stock heat exchanger struggles to keep the
- supercharger coolant temperatures low, especially at high RPM, yielding a
- maximum temperature drop of 8.6F @ 4760 RPM. In contrast, the
- ColdFront Heat Exchanger produced a maximum temperature drop of 13.7F @
- 6960 RPM, and 14.5F @ 7100 RPM when adding the ColdFront Reservoir to
- complete the ColdFront System. This results in a total maximum
- temperature drop of 24F when compared to the stock unit.
-
- Above is a graph showing the intake air temperatures when performing
- back to back pulls on our dyno. (Eight in total using 30 sec.
- intervals). The red line represents the stock heat exchanger, the green line represents the ColdFront™ Heat Exchanger, and the blueline represents the ColdFront™ Heat Exchanger and Reservoir.
- It can be seen that the stock unit suffers greatly from heat soak.
- During the eighth pull the intake air temperatures had climbed upward of
- 180F at redline. In contrast, the larger ColdFront Heat Exchanger
- produces a maximum air intake temperature of slightly over 165F after
- eight pulls. Adding the optional reservoir to complete the ColdFront
- System results in a maximum air intake temperature of just under 165F
- after the eighth pull, with lower temperatures throughout the first
- seven pulls as well.
-
- Above is a graph representing the horsepower produced when performing
- back to back pulls on our Mustang dyno (Four runs in total). The green line represents the wheel horsepower during the first dyno run. The red line represents the wheel horsepower during the fourth dyno run.
- It can be seen that the stock heat exchanger suffered from heat soak,
- resulting in a power loss of 12 WHP @ 6900 RPM. In comparison, the
- ColdFront Heat Exchanger had a power loss of just 4 WHP @6900 RPM. When
- adding the optional AWE Tuning ® ColdFront™ Coolant Reservoir to the
- ColdFront™ Heat Exchanger, there was no power loss at all even multiple
- back to back dyno pulls.
- Below are graphs of the performance testing done with the ColdFront™
- Coolant Pump installed. All tests were performed on the AWE Tuning
- Mustang MD-500-SE AWD dyno using a 7-speed DSG B8.5 Audi S5 equipped
- with G.I.A.C. Stage 2 Performance Pulley Software on 93 octane pump gas
- in a controlled ambient temperature of 85°F.
- Above is a graph showing the supercharger coolant temperature difference
- of the coolant before entering vs. after exiting the ColdFront™ Heat
- Exchanger. The red line represents the pre heat exchanger coolant temperature. The green
- line represents the post heat exchanger coolant temperature. The top
- graph shows the temperature difference the stock heat exchanger is
- capable of producing, the middle graph shows the temperature difference
- the ColdFront™ Heat Exchanger is capable of producing, and the third
- graph show the temperature difference the full ColdFront™ package, with
- the ColdFront™ Coolant Pump, is capable of producing.
- It can be seen that by simply replacing the stock coolant pump with the
- ColdFront™ Coolant Pump, coolant temps are decreased by a maximum of
- 6.2°F @ 4169 RPM.
- Above is a graph showing the intake air temperatures when performing back to back pulls on our dyno. The red line represents IATs recorded using the stock heat exchanger coolant pump, and the green
- line represents IATs recorded with the ColdFront™ Coolant Pump.
- It can be seen that the ColdFront™ Coolant Pump, due to its increased
- flow capacity, yields not only more stable IATs, but also cooler IATs,
- with the IAT temperature peaking at 165°F after eight pulls. The stock
- coolant pump, in comparison, yielded IATs of more than 175°F.
- Above is a graph representing the horsepower produced when performing
- back to back pulls on our Mustang dyno (Four runs in total). The green
- line represents the wheel horsepower during the first dyno run. The red
- line represents the wheel horsepower during the fourth dyno run.
- It can be seen that the addition of the ColdFront™ Coolant Pump to the
- ColdFront™ Heat Exchanger and ColdFront™ Reservoir helps maintain power
- after repeated full-throttle acceleration runs, reducing power losses
- from 23 WHP @ 6900 RPM to just 10 WHP @ 6900 RPM.
