1. B58 Closed Deck setup is what will help the B58 reach bigger numbers safely compared to the open deck N54, there are however people like MMP doing closed deck N54's have seen any reviews though.

2. B58 Vanos at the rear is just dumb from BMW :rage:

3. BMW finally learnt their lesson about using electric water pumps:dunnoanymore:

Only thing is you only need a closed deck n54 if you want more than 750 whp... and that's already allot! on the road do you even need to get it built by mmp to be closed deck? i think only if you want to break records.

b58 might have a Mechanical coolant pump put it makes up for it with Vanos in the rear. Bmw have to make there money somehow :dunnoanymore:
