e90 335i Cooling Fan Upgrade from 600w to 850w

Описание: A fellow n54 guy at the track told me that the 335is has a more powerful radiator cooling fan. So I investigated and found that the 335is does indeed use a 850w fan along with the 1 series M. I found out that the 335d uses the same 850w fan. BMW Performance even has a N54 upgrade kit and this link has a copy of the installation instructions https://www.spoolstreet.com/threads/b... What's also interesting is that BMW Performance makes cooling kit for the M2cs the kit includes a 1000w fan. Can it be that BMW engineers actually made a cooling fan that will help with cooling at track speeds?
