Let's put it this way... If I put 2 brand new cars on the dyno and run them both at 2000 RPM over redline and one blows up before the other I can't really say that car was defective. It was being pushed beyond it's engineered limits. The other car just held out longer. Maybe the car that lasted longer was built a little better, maybe not.
