Exactly, I've run enough cars at altitude and know the effects they have on NA motors.

The CLS 63 AMG trapped at just over 107 at LACR the other day.
Stock 335i's were running 100-102
PROcede/AA Xede cars 104-105

I think a CLS 63 AMG will outrun the M6 Convertible by a touch too.

I remember a test in Motor Trend several years ago when they tested several wagons and ran several of them up to 10,000 elevation mark.
One of the wagons was the BMW 540i
One was a Volvo V40 1.9T

The BMW had 282 hp V8 (had a 0-60 time of 5.9 seconds)
The Volvo had 170 hp turbocharged 1.9 liter I-4. (0-60 time of 7.9 secs)

But they noted at 10,000 feet in elevation they "raced" the two several times and the Volvo would run side by side with the BMW at that elevation.

I remember outrunning a couple more powerful cars with my GTI 1.8T back in 2000 when I was at the Grand Canyon and surrounding areas with an elevation of 7-8000 feet. It was fun.
