DO88 Side Chargecooler Radiator (BMW F8X M2C / M3 / M4)
Product Description
do88 performance radiator for the intercooler system designed for an easy drop-in-fitment in your BMW M3 / M4 F8X
The S55 turbo engine that powers the BMW M3 / M4 F8X 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 space in front of the right wheel arch of our M3 Competition both with and without the bumper. This gave us an exact 3D-model of the available space to build our radiator in. We found that the size of this radiator could be increased considerably both in frontal area and thickness if we also designed a new air ducting between the radiator and bumper cover.
Our final design have a 68mm thick dual row core with multi-channel tubes. We have kept the OEM style single pass flow layout. Our design extends both the core height and thickness by 28mm, all this totals into a frontal area increase of 18% and core volume of a massive 100%. To make it possible to install this massive radiator we designed a beautiful carbon fiber air ducting that is manufactured from prepeg material in autoclave process. Our radiator has a drop-in installation with the OEM cooling lines.
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):
- Greater core volume: 3393cm3 (1693cm3), 100% larger!
- Greater frontal surface area: 499cm2 (423cm2), 18% larger!
- Lower post intercooler air temperature at same conditions: 34°C (39°C), 5°C lower!*
- High efficient core with 8mm fin height of multi-louvered design.
- Multi channel core tubes
* Measured at 240km/h during full throttle acceleration 0-240km/h at air strip. Both tests was performed same day under same conditions.
