Active Autowerke already blows E92 M3 S65 V8 Motor with their Supercharger kit?
It seems that the Active Autowerke supercharger for the E92 M3 has already claimed a motor. We were suprised to learn of this since AA took so much time to come to market and did extensive testing. The vehicle in question has meth in addition to 93 octane so we don't feel this was a fueling issue. If the motor blew with meth as a safety on top of 93 octane it leaves either the tune as the issue or a defect in the motor. Additionally, Active changes the plugs on the motor to colder heat range HKS plugs. Take a look at the shots of the plugs to see that they may have played a part in the motor blowing. The factory plugs are an intricate part of the knock control systeml.
The car itself was a dealer demo car. People beat the crap out of these cars so keep that in mind. I would never buy a demo, you should never buy a demo. There is a reason customers are encouraged to "test" on demos. The motor only had 25,000 miles.
Here are pictures of the installed AA SC:

We will have more as we find out more but it seems there is going to be some explaining to do. Will be interesting to see if the failure was mechanical or the tune itself. For those with Active SC's, we advise you to monitor the situation closely.
