Guys,
anybody knowing anything about the performance of the NE52 on the dynamometer (on engine and on wheels) with the SMG?
I am very curious about the actual performance of my car's engine (530i SMG) and I have not yet seen that piece of info anywhere!
my curiosity, please!

Let's take ~ %15 off of 255hp which is equivalent to ~216hp.

That number is a rough estimate which depends on how heavy the dyno tester is (130lbs or 250lbs which makes a big difference), 4WD or 2WD, drive line effiency, etc.

from all the dyno results i've seen, 12-20% drivetrain loss is fairly typical for all cars
Except for the cars that actually are understated - some can make as much or more than stated values. However, in general some reduction in hp is to be expected.
To the original poster, why are you interested in this figure? IMO, dyno testing is only useful when making improvements to one single car. Just doing it to "know" is a waste of money.

Since my 530 bears an SMG, I want to know whether anybody has actually read something specific.

And if you do some tweaks to the car how would you know the actual gain to the ground if you don't know the original stock value? In this case dyno-ing the car is also pointless.
