do88 performance engine oil cooler is designed for an easy drop-in-fitment in your BMW F8X M2C/M3/M4.
The S55 twin-turbo engine that powers the BMW F8X M2C/M3/M4 has a horizontally mounted engine oil cooler positioned underneath the center cooling module. This stock engine oil have a tube and fin core which is a bit sensitive construction and therefore it can be damaged by road debris. So with this type of core installed in this position it is not very unusual to get a sudden oil leak caused by a small stone or other debris hitting the stock oil cooler and this can be fatal for the engine.
With our performance oil cooler, we like to offer a much more durable design and of course at the same improve the performance!
To get an exact 3D-model of the available space to design our oil cooler in we did a detailed 3D-scan of the mounting area of the oil cooler. With the help of this 3D-scan model we could design a new performance oil cooler with bar and plate core that improves both cooling and strength. Our design increases cooling area by 20% and core volume by a massive 63% compared to the stock oil cooler. Our bar and plate core structure is much more robust so it can handle potential road debris better and on top of that better it offers performance!
Significant advantages with do88 engine oil cooler (stock comparison numbers):
- Improved reliability
- Greater frontal surface area: 1185cm2 (984cm2), 20% larger
- Greater core volume: 4503cm3 (2755cm3), 63% larger
do88 performance radiator for the intercooler system designed for an easy drop-in-fitment in your BMW F8X M2X/M3/M4.
The S55 turbo engine that powers the BMW F8X M2X/M3/M4. uses a Top mounted water-cooled intercooler instead of an “regular” air-cooled intercooler. The coolant in this system has its own separate cooling circuit combined of two parallel connected radiators and a pump. The larger one of these two parallel connected radiators is positioned in the front of the center cooling module, the second smaller one is located in front of the right-side wheel arch. Reducing the water temperature in this circuit is directly equated with improved cooling of the charge air (lower IAT). Due to this reason, it is important to have high performance radiators in this system to maintain as low and stable IAT as possible during tough driving. During all test we have carried out during the development of our entire BMW F8X M2C/M3/M4 product range we see clearly how the peak power is directly equated with the IAT (Intake Air Temperature).
When designing our upgrade performance radiator, we started with 3D-scaning the front of the center cooling module of our M3 Competition. This gave us an exact 3D-model of the available space to expand the core in. Since this radiator is positioned in the front of the center cooling module, we have optimized the frontal area / thickness / fin specifications to maximize the cooling performance but in the meantime allow enough air to flow through for the other cooling components behind it. It is critical to design a radiator positioned in front of others with a system view instead of just optimizing one part leaving the others over heated due to insufficient air flow.
Our final design is a 32mm thick single row core with multi-channel tubes. We have kept the OE style dual pass flow layout which allows the coolant to flow across the core two times before exiting the radiator. Our design extends the core height by 166mm and the thickness by 5mm all this totals into a frontal increase by 48% and core volume by a massive 75%. These improvements have in our tests resulted in a 5°C IAT reduction in combination with our side mounted radiator upgrade.
All this hard work result in a product that in one way or another really will enhance the performance of your vehicle no matter if it is a standard car or a heavily modified monster! On track, on street, on strip, this radiator will be your true companion!
Significant advantages do88 radiator (stock comparison numbers):
