The ColdFront Heat Exchanger
The AWE Tuning ColdFront Heat Exchanger was developed to reduce
high air intake temperatures found in supercharged engines. Designed and
conceptualized in house at AWE Tuning, the AWE Tuning ColdFront Heat
Exchanger should be a mandate for supercharged 3.0T engines looking to
keep things consistent and reliable.
The AWE Tuning ColdFront Heat Exchanger is a direct replacement
for the factory heat exchanger, fitting neatly behind the front bumper
and grill assemblies. This product was specifically designed by the
engineers at AWE Tuning to include a unique drain plug and bleed screw,
allowing the system to be bled without the need for external tools. In
other words, all the benefits of a cooling upgrade with none of the
fitment downsides.
Why a heat exchanger?
Insufficiently cooled air entering your vehicles engine will rob
power and performance. Modified vehicles, notably those flashed and/or
equipped with a modified supercharger pulley like the AWE Tuning Stage 2
Performance Pulley, are particularly susceptible to higher intake air
temperatures. Enter the AWE Tuning ColdFront Heat Exchanger: Proven
to maintain consistent intake air temperatures and power, even under the
most demanding of conditions.
How it works
The AWE Tuning ColdFront Heat Exchanger utilizes a larger frontal
area, resulting in in cooler supercharger coolant temperatures, leading
to better air intake temperatures and consistent, reliable power.
Partner products:
The AWE Tuning ColdFront Heat Exchanger can be used either in
combination with other members of the AWE Tuning ColdFront product
line, or it can be used as a stand-alone upgrade. Presenting the AWE Tuning Audi 3.0T ColdFront System. Designed in
house at AWE Tuning, our ColdFront product line is the solution for
consistent and reliable performance for modified vehicles looking for
maximum power and security. AWE Tuning ColdFront products are
available in the following configurations:
- Package: The full ColdFront product suite, featuring the AWE Tuning ColdFront Heat Exchanger, ColdFront Reservoir, and ColdFront
Coolant Pump.
- Package: The ColdFront Heat Exchanger and ColdFront Reservoir
- The ColdFront Heat Exchanger alone
- The ColdFront Reservoir alone
- The ColdFront Coolant Pump alone
- The add-on ColdFront Protection Screen
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.
