All good and well to build up motors to ludicrous hp levels, but some of these companies want them to go out the door and know that they won't break.

Touring the AMG factory last year in Stuttgart, we were told that many an AMG customer were ex Brabus customers who broke everything they ever bought.

AMG's less is best policy ensured that things did not break. I don't have a lot of faith in the super hp conversions.
