Here's a thread I started over at bimmerfest that describes my experience with software that actually is pretty accurate:

This is a follow up to the other thread that discussed how underrated (if any) the hp and tq are on the 535i.

I bit the bullet and paid $12 for the NxGTR sim software. You can read about the software here: http://www.nxgtrsim.com

I wanted to see if the 8 speed transmission made as big of a difference as I thought it would when compared against the 6 speed of other vehicles used to guess the 535i's true hp.

It turns out, the 8 speed makes a bigger difference than I thought.

I basically inputted all of the information I knew about the 535i automatic, my weight of 185 pounds, and ran it. The results were very much inline with actual reported track times from actual 535i owners.

Here are the results:

Time to Speed
0-30 mph: 1.873
0-60 mph: 5.424
0-100 mph: 13.83
0-200 kmh: 22.85

Time to Distance
0-100 m: 5.887 @ 63.2 mph
1/8 Mile: 8.997 @ 81 mph
1/4 Mile: 13.94 @ 100.4 mph
0-1 KM: 25.46 @ 129.5 mph

Top Speed
172.93 @ 96.92 s

At the end of the day, while horsepower is cool, it is not everything.

I've attached screen shots of the settings I plugged into the software. Not shown in any of these screen shots is my 185 pound weight, which was used in the simulation. Please let me know if you see any errors in what I plugged in. I believe I was accurate.
