UPGRADED HEAT EXCHANGERS BOOST POWER OF SUPERCHARGED CARS AND TRUCKS

 

The Great Supercharger Power Robbery Solved!

Defeat heat soak and power loss with an upgraded heat exchanger

Upgraded supercharger heat exchangers for Mustangs, Ford F150 trucks, Cadillacs, Corvettes, and Camaros can improve the power of your ride by up to 20% with a bonus of maintaining the ignition timing and the fuel delivery optimal by increasing the coolers' duty cycles and halting the dreaded heat soak crisis. Units with fans are plug-and-play and they come with Spal fans and complete wiring, thermostats, and controls.

 

WHY YOU SHOULD  INSTALL AN UPGRADED HEAT EXCHANGER!

You see, the stock heat exchangers are very narrow, so they have a low duty cycle. Stock heat exchangers heat-soak rapidly, especially in hot climates or when you push the engine across its threshold of power and cooling ability.

OE manufacturers build their vehicles for "NORMAL" use! Well, you don't do normal now, do you?

 

No normal for you!NO NORRRMAL FORRR YOU

 As a "lead-foot" you know that hot laps around a racetrack, spirited driving, or repeated passes at the drag strip have nothing to do with normal driving. There, the event can exceed your original equipment manufacturer’s heat exchanger’s duty cycle, and it becomes overwhelmed with the dreaded heat soak syndrome.

HOW DO AIR TO WATER HEAT EXCHANGERS MAKE POWER?

Heat exchangers need a pump to circulate the water from a tank which is independent of the engine cooling system, through the heat exchanger where it is cooled. Then the water is directed to the intake plenum that contains a cooler through which the intake air dissipates the excess heat it gathered during the compression process. High volume heat exchanger pumps are available from Appliedspeed here.

The rectangular part sandwiched between the intake plenum, and the intake manifold contains the core where the freshwater flows to cool the air intake before it enters the engine.

Air-to-liquid heat exchangers hold their cooling fluid in a small tank, independent of the primary engine cooling system. A pump circulates the fluid through the cooler installed at the engine radiator exposed to the air flowing through the cowling. The cooled fluid only does its magic when it reaches the core beneath the supercharger, where it refreshes the intake air as it passes through it. Performance racing heat exchangers have a high cycle duty so they can repeat this function several times without heat soak.
The upper part of this photograph describes how the freshwater in blue flows through the heat exchanger where the air in red extracts the heat from the matrix. The part at the bottom of the picture is from the cooler under the intake plenum. There the hot intake charge transfers its excess heat to the cool water before it enters the intake manifold.
AFCO's upgraded heat exchangers are twice as thick as the stock variants. This feat and other cooling techniques developed in professional racing yield a 350% improvement in cooling the intake charge over the stock units.

C&R Tubes heat exchangerC&R Racing brings the same extruded tube technology they supply in Formula 1 and NASCAR radiators and heat exchangers to your late model street or race car. The image shows the partitioned extruded tubes that cause the fluid to swirl and lap the whole internal surface of the tubes for maximum heat dissipation. The partitions nearly double the heat sink surface, and they reinforce the matrix. 

Are you one who can benefit from an aftermarket upgraded heat exchanger

Is your car equipped with a supercharger? Are you one who has an eye on performance? On-off the gas a lot? Weekend drag racer, road racing, time trials, autocross, solo events, or just a high-spirited driver? Is your ride an LT swap? Use your F150 to tow a trailer or a race car? 

Heat is Power. Heat Kills Power. Heat is a Double-Edged Sword.

AFCO double passThe double-pass concept utilized by AFCO Racing in its heat exchangers (and radiators) channels the water through the radiator twice. The double-pass design creates a restriction that increases the pressure in the fluid. This event causes the fluid to lap the inside of the tubes to increase heat transfer, and to avoid it from forming a wall against the tubes. Formula1, Indy Cars, and NASCAR Cars utilize this concept extensively in their heat exchangers, radiators, and oil coolers.

Lawsuit depicts the urgent need for additional cooling in high-performance cars and trucks.

To what extent is an upgraded heat exchanger necessary?  Now, hear this!

This lawsuit demonstrates how manufacturers build their cars for "normal" driving but when pushed beyond their envelope limits heat can cause undesirable effects like sending the engine in “limp mode”. Limp mode cuts the engine's speed, and slows the vehicle to a snail's pace, potentially putting drivers and passengers "at risk of crash and injury."

Ford has sold these Shelby GT350 vehicles as track cars built to reach and maintain high speeds, but Ford has failed to disclose that the absence of some coolers can greatly diminish the vehicle's reported track capabilities. https://www.motorauthority.com/news/1109557_2016-mustang-shelby-gt350-owners-suing-ford-say-track-ready-cars-overheat-too-quickly

 

Older Chevrolet Muscle Cars often get an LT swap and a supercharger to boot. Many drivers of those cars have reported hot running and heat exchanger heat soak. The newer Muscle Cars like the Ford Mustang Cobra in this photo often sport a supercharger and a stock heat exchanger. Both types of cars benefit from an upgraded heat exchanger.

 

Are you still wondering why you should install an upgraded high performance automotive air-to-water heat exchanger on your supercharged engine?

Replacing your old factory heat exchanger in your car or truck with these modern replacement ones is the undisputed solution to increase intake cooling efficiency, torque, horsepower, and the duty-cycle of the cooler.

The new and upgraded performance heat exchangers supply your engine with a denser oxygen-rich charge. Upgraded heat exchangers are three times more efficient than the stock ones so they can lower intake temperature up to 50° F over the stock units, and they carry a duty cycle several times higher than the OE units for repeatable performance. They are laser cut aluminum TIG-welded construction with NASCAR and Formula 1 technology of extruded tubes with internal fins.

Major Benefits Include:

  • Aftermarket performance upgraded heat exchangers cool 350% better than the stock variants  
  • Higher intake air charge and oxygen content for higher HP and torque.
  • Drastically improved duty-cycle for repeatable, reliable power.
  • Direct bolt-in using factory bolts and hoses, saves time and money.
  • Improve ETs and lap times! You can win more!
  • Minimizes heat soak reduces timing retard and fuel enrichment for reliable and improved power.
  • Prevents engines from going into limp mode, for safety and reliability.
NASCAR standout Smokey Yunick stated in his books: "Each ten degree of temperature reduction equals from one to two percent in horsepower increase."

Experience Additional Benefits

High intake air temperatures also affect timing and fuel injection. When overheated, the intake air can cause detonation and engine damage. At that time, the ECU pulls timing to prevent detonation, and it corrects the fuel delivery; but those adjustments further reduce power by an additional 10 to 20%!

 

This photo demonstrates how crowded engine compartments have become in modern automobiles. The lack of space prevents the hot, expanded air that has passed through the radiator and coolers from escaping. Not only does the air heats the engine bay, but since hot air expands, it also creates a high pressure that forms a barrier to the exterior air from flowing through the cowling.

 

Heat is a double-edged sword. While intake charge coolers remove the excess heat, the result is an air mass that is two to three times its initial volume. Chrysler solved the under-hood hot-air-stuffing challenge with generous vents through the fenders and in the hood. These modifications helped to prevent overheating in hot climates and when racing. Further, reducing high pressure under the hood encourages better handling, acceleration, and top speed.

 

Air-to-Water or Air-to-Air?

Water is a much better heat transfer agent than air. Any cooler will benefit greatly from using water as a heat transfer medium Air-to-water coolers are easier to package, and they do not "heat soak" as readily as the air-to-air types. As such, they are ideal for daily driving.

Whether you drag race, drive in autocross, or just use your supercharged truck to tow a trailer, you can experience significant driving improvements with upgraded air-to-water heat exchangers.

Reducing the intake air temperature also affects timing and fuel injection, which could cause detonation, limp mode, and engine damage. But here, the ECU is the savior as it pulls timing to prevent detonation, and it corrects the fuel delivery. Those adjustments further reduce power by an additional 10 to 20%!

 

ATTENTION READERS

Beware of copy-cat, imported knockoffs, and even counterfeit units whose manufacturers disregard all best practices. Those are often peddled on eBay and by sketchy overseas websites.

Buy from reliable and trusted sources, well-established manufacturers. At APPLIEDSPEED.com we only sell Made in USA cooling solutions. There you can purchase the latest iterations of upgraded truck or car heat exchangers from trusted American manufacturers like C&R and AFCO.

 

Some race cars like these drift cars at Irwindale Speedway in Southern California rely on upgraded heat exchangers to keep their intake air cool. Drift cars spin their superchargers or turbos at full tilt as the runs can be at wide-open throttle for several minutes. Dependable and repeatable power is crucial in this form of racing. The drivers upgrade to high-performance supercharger heat exchangers because they cannot count on reliable power when they need it with wimpy heat exchangers. Note to what extent the air intake opening has become restricted from the cars driving sideways. (Ed.)

 

Why Does Temperature Affect Power?

Heat is Power. Heat Kills Power. Heat is a Double-Edged Sword.

As pressure increases, with temperature constant, density increases. Conversely when temperature increases, with pressure constant, density decreases.

www.skybrary.aero › index.php › Density_Altitude

Compressing a gas increases the amount of oxygen it contains, but compressing a gas increases its temperature and reduces its density. The higher the temperature delta between intake and combustion, the higher the power the engine can make.

Theoretically, when you reduce the intake pressure by 1 PSI, it increases power by approximately 7 percent...but, there is a price to pay!

Superchargers are compressors. As Charles' Law dictates, the pressure of a gas is directly proportional to its temperature. As such, if we increase the pressure of the air intake, we also increase the temperature by a proportionate amount.

Charles' Law dictates that the temperature of any gas is directly proportional to its pressure. As such, if the ambient air temperature is let's say, 70 degrees, and the supercharger further compresses the air to an additional 14.7 PSI, the intake charge now reaches 140 degrees. Click the image and see it work.

NOTE: Charles' Law is more complicated than can be detailed here. For the full formula link to https://en.wikipedia.org/wiki/Charles%27s_law. For our purpose where ambient temperature averages around 70 degrees F, we can assume that every 10 degrees of temperature change impart a power change of one to two percent.

 

This image demonstrates the difference in thickness between a stock heat exchanger at the top with an upgraded one from AFCO. The increased thickness allows for more material to absorb heat and more surface for the air to dissipate it. Manufacturers like AFCO and C&R rely on their racing experience and utilize the same principles developed for their racing radiators to their heat exchangers.

Ease Of Installation

The cooling products sold by Appliedspeed.com are from reliable manufacturers who test their products on the track and with professional racers.
