FDS (FLOW DISTRIBUTION SYSTEM)

The IE FDS (Flow Distribution System) has proven to distribute charge air uniformly across the inlet end of the core. In contrast to other intercoolers on the market, which rely on natural airflow across the core, our FDS technology uses precisely shaped and placed fins cast into the inlet plenum to fully take advantage of the large core volume effectively using the entire core. As a result, the IE FDS intercooler has been proven to reduce IAT (intake air temperatures) more so than competing intercoolers, thus offering the largest power gains possible.

 

TECHNICAL FEATURES

 

Increasing the horsepower of your B9 is a simple task with several tunes and upgraded turbos available. However, it is important to keep in mind that increasing horsepower will result in heat soak of the stock intercooler and parasitic power loss. The IE front-mount intercooler system was designed to replace the factory unit directly while utilizing a much larger core and our proven FDS (Flow Distribution System) to effectively utilize that larger core. These features allow for much higher cooling efficiency than the factory system, thus reducing intake air temperatures and safely increasing horsepower output. The IE FDS intercooler is also a direct fit, requiring no cutting, modification, or time-wasting hassle during installation. Read below for more in-depth information on each intercooler feature.

 

ELIMINATE HEAT SOAK

 

Heat soak occurs when the heat generated exceeds the cooling capacity of the intercooler. The most common symptom is the noticeable loss of power after long-term acceleration, or several back-to-back power pulls. By greatly increasing the core size and useable area of the core with FDS technology, we have eliminated the heat soak, keeping the intake air temperatures consistently lower than OEM and competitor intercoolers.

PRECISION ENGINEERED

 

Unlike other intercoolers put together to fit on the car and offer a larger core, the IE FDS intercooler line receives special treatment from start to finish. Our engineering department uses Computational Fluid Dynamics (CFD) software to optimize the end tanks and FDS system for minimum pressure drop and maximum flow and cooling.

 

DECREASED PRESSURE DROP

 

Along with lower intake air temperatures, the large core within the IE intercooler also decreases pressure drop compared to the factory unit. Simply put, pressure drop is the amount of pressure that is lost as air travels through the intercooler. As airflow boost pressure is raised, pressure drop typically begins to climb. Using a larger core that flows much more freely than the factory core, the pressure drop is reduced, decreasing the need for the turbocharger to work harder to produce the required boost levels. This allows the turbocharger to deliver more usable boost pressure to the engine. (See dyno chart in power charts tab)

 

HIGH-QUALITY CONSTRUCTION, PERFECT FITMENT

 

Not only does it offer the highest cooling efficiency on the market, but the IE FDS intercooler also offers perfect OEM replacement with absolutely minimal modification. It has CNC machined mount points, and every IE intercooler allows you to reuse the factory mounting points and installs as if it were a factory piece. You will also find that the IE intercooler receives the same attention to detail and quality as every other IE product, with cast and machined end tanks, precise TIG welding, and a dense bar and plate core. Every intercooler is tested on our in-house intercooler testing station before shipping, ensuring that it is ready to install.

 

COMPLETE KIT

 

The kit comes complete with one FDS intercooler and all hardware needed for installation.

 

INSTALLATION

 

Install for the IE B9 FDS Intercooler will require a standard toolset, a couple of torx bits, and some technical expertise. We recommend reviewing our install guide and install an overview video before attempting the install.

 

HORSEPOWER & TORQUE RESULTS

 

The IE Audi B9 FDS Intercooler increases horsepower & torque by decreasing IAT (intake air temperature) and reducing knock. This makes your car much more predictable and consistent because it will not rapidly soak like the OE Intercooler.

 

 

PRESSURE DROP RESULTS

Typically upgrading to a larger intercooler core results in added pressure drop, resulting in power loss. IE's FDS design eliminates this problem and delivers more boost to the engine by minimizing pressure drop across the intercooler. On the B9 platform, our FDS Intercooler reduces Pressure drop from 1PSI to .3- a drop of approximately 70% at Stage 1 power levels!

 

INTAKE AIR TEMPERATURE RESULTS

Our unique IE FDS Intercooler design for the Audi B9 platform consistently results in an IAT drop of approximately 20C-30C average at the end of open throttle pulls compared to the factory intercooler.

 

 

IE FLOW DISTRIBUTION SYSTEM (FDS) FLOW RESULTS

The highly engineered FDS design unique to IE intercoolers uses a carefully shaped fin system located inside the intercooler end tank to force the intake air path. This ensures charge air utilizes the full intercooler core more effectively than conventional intercoolers resulting in less pressure drop, lower IAT temps, and more power resulting in the most efficient intercooler design on the market.

FAQ

At what point will I need the IE FDS intercooler for my car?

With extensive testing, we have found that all B9 chassis vehicles have very poor factory intercoolers and can benefit greatly from our intercooler upgrade. Most beneficial on vehicles equipped with stage 1 software or higher, it is necessary to upgrade with a big turbo setup.

What all is included with the IE FDS intercooler?

The intercooler kit includes the direct-fit core, install brackets, necessary bolts and washers, and an installation manual.

Are there any modifications required to install the intercooler?

No! The IE FDS intercooler is a direct replacement for the applications listed above. There is no trimming, cutting, or modification needed for installation.

Do I need to purchase anything else to install the IE FDS intercooler?

This intercooler includes all necessary hardware and parts for installation.

What kind of power increase will I see with the IE FDS intercooler?

The power increase is dependent on the tune or turbo setup and the boost levels that you are running. Tuned ECUs and larger turbo setups run higher boost pressure, higher boost yields larger gains with the IE FDS intercooler.

How much horsepower will the intercooler support?

We have tested the IE FDS intercooler to over 600hp successfully with room to grow. Supported power is in the 650-700hp range but will ultimately depend on the turbo setup and operating conditions.
