The crankshaft drilling issue, I took my photos from the Rennlist, I have them and can send them to you or you can try a search first.

O.K on the rpm limit, my friend is an engineer and we did some mass calculations and 7250 is under the same mass forces with the lighter weight components, that is hollow stem valves and Ti retainers for the top end and for the bottom end lighter forged pistons and pins along with lighter than stock rods, balance pads and square edges removed.
O.K to the dry sumping, where to put the oil, BMW thought lets put it in a sealed container in the sump! What a good idea I said, I'll copy that. I will also use a small recovery tank that will has some capacity for oil storage.
Three stage compact size hopefully will fit but the two stage will. One stage front and rear and one in the middle.Drysump pumps
Thanks Greg for sharing.

Thanks Greg,
Still a ways off, but needs to be done.
Also, with the smaller battery box, I'm assuming the battery is smaller on the later models as well??!!

Greg Gray,
I can't tell exactly what you have done, and what you have'nt by the wording of the title post, but you got some serious stuff going there.
More info on the exhaust valve please!
Forget BMW, the Cayenne's have an in-sump oil reservoir:
