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.

First off, where does this 26 hp increase to 440 N55 number come from? Do you know something no one else does about the F80/2?
I don't have time to look up the Dinan S65, but I doubt it's making making more than 400lb/ft from about 1500 rpm as the new engine most likely will or achieving more than 25 highway.
I love the V8, but i refuse to discount the heavily modified 3 liter turbo until independent road testers and myself have had a chance to drive one. The 4.4TT in the M5 is towering.
