Now the engine is shot, no wonder. The Hahn Stage II installation manual clearly states not to drive the car if you have knock.

The Hahn kit and any other after market performance add-on is just that, an after market performance mod. When you "hot rod" any car you are taking a risk of blowing something up, it doesn't matter what the mod is (super charger, turbo, tune, etc.). When you mod a car you are trying to make the car respond to your extreme driving needs, so a modded car is generally pushed to the limits by its driver. Catastrophic failures in modded cars sometime have to do more with how the car is being driven than the mods themselves. If drive any car hard enough, stock or modified, you will have catastrophic failures.

I blew up the motor in my supercharged Boxster a few weeks back. I didn't go onto the Boxster boards and start crying that the supercharger kit I installed made the thing blow up. Me pushing the car beyond it's limits was the culprit. As a side note I just bought a Cayenne Twin turbo SUV yesterday (520 HP), it makes my Boxster and Sky seem slow. I know this forum frowns on kill stories but I can gleefully report that one Z06 in my town was embarrassed by an SUV cleaning his clock. My new SUV handles better than my Sky, thats just ridiculous. I digress.

Your post has been flagged unsubstantiated because it is just that. You heard that someone toasted a motor and they happen to have had a Hahn system installed. You are providing a third party account without even knowing the particulars of the engine failure or the circumstance of when it happened. I myself consider this rumor until I hear it from the horses mouth and all of the facts are presented.

I'd like to see how well your Cayenne Twin-turbo would hold up against an Audi R8.
