Description

Product Description

FMINT24 is a performance intercooler for the 2021 onwards MQB platform 2.0 DNF code EA888 EVO4 engines. Produced, designed, and tested, at our headquarters in Gloucester UK. Throughout the development process we have strived to improve the efficiency and performance of the EA888 GEN4 engine. Our project brief was to develop an intercooler that utilised all of the available space in the original position of the OEM intercooler, and to ensure the inlet air temperature is reduced, without any negative effects on the boost pressure or engine and transmission cooling.

In the MQB chassis the intercooler housing is particularly restricted and confined to a small amount of space, due to it not only housing the intercooler, but also the radiator and air conditioning condenser. The front panel in theory is a sandwich pack that houses the auxiliary cooling components. This means in order to increase the size of the intercooler without paying detriment to the performance of the surrounding items, and with also having very little extra space available, that it can be very difficult to execute the perfect blend of a high flow intercooler within such a close proximity.

Our research and development engineers started with a brief to fit our existing intercooler (FMMK7FMIC) that was for the MK7 platform, to our development VW MK8 Golf R. Upon installation, we then tried to establish if we could re-engineer the intercooler with an increased inlet and outlet size along with increasing the volumetric capacity to increase flow along with future proofing the design to work well with highly tuned stage 3 plus EA888 Gen 4 engines.

Using a combination of scanning software and traditional measuring methods, the design was created. This was then fine-tuned by our flow dynamics simulations programs (CFD), and the end tanks were initially created by 3D printers. This enabled us to ensure the fit was perfect on the vehicle before any prototype castings or machined billet end tanks were produced ready for dyno testing.

Several baffle configurations were designed, and flow simulated to ensure the maximum performance was obtained to keep the core working at its optimum, along with ensuring all its cooling capabilities had been upheld, and that the total volume of the core internal is utilised for optimum performance.

With an increase in inlet and outlet sizes, we then turned our attention to the design of our silicone hoses. With flow in mind, we have created a step within the hose so where the hose meets the hot and cold side of the inlet and outlet junctions the transition is seamless, this helps to lesson any disturbance to the airflow and prevent unwanted turbulence. To further aid with flow, the inlet and outlets have been increased to 76mm from the OEM size of 63mm which equates to a 45% increase in surface area.

The consideration of space and our clever design has led us to produce several intercooler cores with different fin configurations and internal capacities. Depending on the core design, testing results led us to choose a bar and plate design with over 83% more volume than the OEM intercooler, and with a frontal area increase of 10%.

Why do we test different cores?

Here at Forge Motorsport, when developing an intercooler, we will test several different cores for each application. For example, a bar and plate style core, a tube and fin style core along with different fin pitches and heights, as well as changing the internal fin pitches/shapes and density within the tube; thus enabling us to fine tune the amount of pressure drop the intercooler produces. Pressure drop is not always a bad thing, as our testing and research has proven on various projects. This is because the pressurized air velocity is being stalled by the pressure drop within the cooler thus allowing more time to cool the air within the cooler itself, as air passes through the non-pressurized face of the core, that is open to the atmosphere. 

Too much pressure drop can of course have a problem on the higher performance engines as the intercooler reaches its maximum efficiency the turbo has to work a lot harder to force the air through the core. This in turn creates higher inlet air temps (IAT’s) due to the turbo creating more heat as it is over stressed and worked harder. No pressure drop can also prove to be inefficient as the cooler will not lower the charge temperature again resulting in higher inlet air temperatures.

Dyno Results

Testing was completed using Performance Remap in Gloucester with their VTEC 4-wheel drive dynamometer. This was to ensure all our data has been achieved with results as accurately as possible by an independent tuner. As you can see from the dyno results below, peak power was increased from stock by 11bhp and 20nm of torque at 5500RPM with the Forge Motorsport performance intercooler installed.

The best news is that there are significant torque gains throughout the rev range, meaning that the car power will pick up quicker and pull the whole way through to redline, including an impressive gain in BHP from 5000 RPM TO 6500 RPM. Gains on vehicles with re calibrated software and further hardware performance parts can be expected to be a lot higher due to the substantial drop in IATS when FMINT24 is installed.

During our extensive testing, we let the car heat soak on the dyno until the radiator fans tripped on and off (which gives an inlet temperature of around 40°C). We then did a dyno pull from this point which gives a more consistent result and reflects real-world driving conditions more accurately. You can easily see the Forge intercooler cools much quicker and delivers a much greater drop in temperature compared to OEM.

 

 

After more than six pulls on the dyno we still had super safe IAT’s, and the Forge Motorsport intercooler gave results of 34°C at 6548 RPM giving a reduction of 58% over the factory’s intercooler intake temps from 58°C at 6508 RPM. These tests took place in relatively hot conditions with an ambient dyno cell temperature of 23°C proving how inefficient the stock intercooler is.

In the summer months, the stock intercooler along with higher inlet air temperatures will have a hugely negative impact on the engine’s performance. In these conditions, the engine management will retard the ignition, resulting in a lower powered engine as temperatures rise and the ECU then pulls out the timing to stop detonation. On a mapped vehicle, the results will be even more detrimental and can lead to possible premature engine wear. If you use your car for fast road or have a high-performance tune in a hot climate, this product is essential. 

Why do we try to decrease IAT's? (Inlet Air Temperature)

Temperature and volume of air supplied to your vehicles engine that is compressed by the turbo charger has a better effect on performance when cool as this is to provide the engine with more oxygen (denser air), thus improving the combustion in each cylinder. In addition, by regulating and reducing the air temperature, it also increases the reliability of an engine by keeping the AFRs (Air Fuel Ratios) in each cylinder at a safe level, which in turn, can increase an engines power due to the air being cooler. A bigger bang is then created within the cylinder, providing the correct amount of fuel is added. This can equate to an increase in BHP and torque.

​​​​

The Forge Motorsport intercooler is a perfect performance enhancing product that fits directly to the OEM mounting points, making for an easy install, in a relatively short period of time. No cutting of any components is needed, making the installation reversible if the vehicle needs to be returned to stock at any time in the future. The core and end tanks are finished in our black textured anti corrosion coating that also aids with its thermal properties and keeps the product looking that bit stealthier or OEM+.

The Forge Motorsport lifetime warranty on all hardware products shows the trust we have in the quality of our products while they are being enjoyed on your pride and joy.
