S58 Technical Document
- Thread starter doublespaces
- Start date
Unlike the introduction of the N54, it looks like BMW is taking cooling in a competitive environment quite seriously in the S58:
According to BMWBlog:
“Three large radiators, an additional engine oil cooler and a separate transmission oil cooler keep the temperatures under control. A map-controlled oil pump with additional suction stage in conjunction with the oil sump, which has two chambers and an integrated suction channel, enables reliable lubrication even at high lateral accelerations.”

Here are cliff notes:
They've dropped the CR from 10.2 to 9.3
Oil sump is cast aluminum AlSi9Cu3
Crankcase is gravity die-cast Al Si 7 Cu 0.5 Mg
And everyone's favorite subject:
Crankshaft is a steel alloy 42CrMoS4 Mod which is nitrocarbonized. Lower bearings are Federal Mogul G488 and uppers are G490. Rods are taken from the S64B44T4.
Forged 'slipper-skirt' pistons are made by Mahle. Material is M142P alloy.
The turbos are off-set and the turbine housings are part of the manifold:
DME is made by Bosch: DME 8.6.S (Gen8, 6 cylinders, M Sport)
