My regret (not even a problem) was that when moving from E to F, BMW matched gearboxes and diffs more closely to stock engine torques, which in my mind was a bit of step back, because you could always count on 3 things with BMW gearboxes in the past 1. they did not provided greatest feedback 2. they always had decent of headroom potential tune 3. every-time you changed gear you felt like you reloaded WW1 full caliber rifle.

Original BMW coolant (the one in 1.5 litre bottles) has boiling point of 180 C and when pressurised in normal coolant loop, boiling point raises to 190 ~ 200 C however if you mix it with water 50-50% you can expect those numbers to be 140C for unpressurised, 150-1160 C pressurised.

From what Ive seen at the dyno where some inexperienced or know better then the test schedule requirements technician used pure water for cooling on endurance or long term emission tests, cooling pump seals and joint between shaft and plastic prop would fail first but on my car it was not the case so far, so as usual T&C applies, your milage may vary. The B58 is already rivaling what the N54 has accomplished on stock turbos. Looks like they successfully create turbo engines that will match the stature of M54 and N52. Thank you.
