Talking WAGNERTUNING Radiator Kit BMW F-Series B58 Engine

The 3.0 Liter B58B30M0 turbo engine of the specified BMW models is equipped with an indirect charge-air cooling circuit. So the cooling of the charged air is not realized by the ambient air as cooling medium (as usual), but made with its own cooling water circuit. A reduction of the temperature of the cooling water is directly equated with an improved cooling performance of the charged air. This is exactly where the advantages of the WAGNERTUNING upgrade radiator comes into play. The new developed competition racing core of the WAGNERTUNING high performance radiator increase the radiator volume of the OEM water cooler by a total of 117 %. The calculated ratio between the inner and outer cooling surface generates a maximum heat transfer and allows at the same time enough air flow for the surrounding components (for example the engine radiator) for its own heat exchange. Furthermore, using an increased amount of cooling water, the entire system thermics can be kept at a lower level over a longer period of time.

All WAGNERTUNING radiators are equipped with a heat-conductive anti corrosion coating to ensure a lasting cooling effect. The plug & play installation of the system is simple and easy to perform (an installation instruction is included as well).

Dimensions OEM radiator:
576 mm x 495 mm x 27 mm
V = 7,70 Liter
A = 2851 cm²

Dimensions WT radiator:
524 mm x 468 mm x 68 mm
V = 16,70 Liter
A = 2454 cm²

To ensure I get it right - this is an upgraded radiator specifically for the charge cooling system.

Is there a series of typo's in the specifications?

I'm told the engine coolant capacity of the B58 is around 7 litres. You list 7.7 litres for the intercooler coolant, which doesn't make sense, as there would be significantly less in this circuit.

Then the WT one holds nearly 17 litres? I'm pretty sure an at least 10kg coolant increase is not going to be a good performance modification, especially as there isn't a documented issue with uncontrollably high intake temps. (My track day logs show pretty consistent AIT lap after lap)

The quoted “volume” is purely the space the intercooler radiator takes up (length x height x width), the coolant volume is going to be much less than that figure, probably about 25%. Notice also that the OEM intercooler radiator has a higher surface area, so will allow a greater air flow through it, but heat transfer on the Wagner one will be higher for a given surface area due to the extra depth, basically less air flow with a higher temperature increment in that air from front to back of the intercooler radiator.

Gotcha.

If only it worked like that huh! I'm talking thickness of core. Think I'd need empirical data before I was convinced a thicker radiator was actually an upgrade.
