I have a hard time buying into your money emphasis.
The increase in horsepower between the current V8 and the new N55 (414 to 440) is a mere 26 HP. Dinan, as an example, gives you more than that (without turbo's) on an S65 + a substantial torque increase. A Dinan S65 cost 25k but If BMW put a Dinan like engine into assembly line production, I bet it would add, max, 5k to the cost of the car. I'm not sure, but ,to me, the re-worked N55 is going to add that and maybe more.
It just seems that some inexpensive off-the-shelf tweaks done by BMW (routinely done by tuners) to the S65 could have achieved the same power/torque performance as its evident replacement and at less cost.
