Testing CSF Charge Coolers for the F10 M5/F13 M6
After the impressive result of the CSF Intercooler for the F87 M2 we were keen to see how big of a difference the CSF Charge Coolers for the F10 M5/F13 M6 could be.
When tuning these cars the standard charge coolers start to struggle with keeping the Air Inlet Temperature down, meaning the ECU will start to pull Ignition Timing, and not making full power. This can be quite a big problem especially in hotter climates.
The CSF coolers are a full metal design, with cast end tanks and having been designed to maximise volume by utilising 3D Scanning and CFD to optimise flow. They also feature ports for an injection system such as Water/Methanol. In our testing they performed exceptionally well, with IAT temperatures 14c better than stock, but in hotter ambient conditions, meaning in identical conditions they should perform even better than our testing.
