Haha, no flames that I know of at this time 
As for how it sounds, it's definitely different from the M96 flat 6. Not as smooth. It's got lots of the typical turbo bov/compressor surge sounds. It does sound pretty mean, especially when going through a freeway underpass or through a tunnel. 
Here's a video clip that Kent took while tuning the car earlier this year.

From the inside, it sounds pretty similar to his setup, just a little subdued due to me running a full interior. You can hear it in one of his race videos too. The engine in the video is now in his street car.

Nice .....can you contrast and compare torque curves? Do you feel there is a lot lost on the bottom end?
