    AA absolutely will be allowed to respond, no reason they wouldn't.

    Again a bash the vendor story.... I'm always wondering a bit about the purpose. And with the highest respect, why should a company go public on Bimmerboost? Is this a court? I mean let them do their business, people do not have to buy stuff from them. And that is something completly different that a shame and blame approach bimmerboost intends to take, is bimmerboost a party in this issue? Don't think so.. so why should they come to you? Because you force them by a one side story? Does not look that well! Focus on technical content and sharing knowledge and experience... this looks very negative for this nice site...

    I wasn't insinuating you weren't going to, I just felt this thread was not fair as AA needs their opportunity to say their end of the story and I felt the first page or so was not fair to them, that's all

    I hope I did come off the wrong way there, guest vendors are allowed to post for this very reason. We'll see what AA has to say.

    Got this in my inbox:

    Click here to enlarge Originally Posted by viral@activeautwerke.com
    To address the allegations laid against us by Jordan Russ of Import Motor Werks, formerly M Powerered Automotive, please see as follows:

    Jordan purchased a Level 2 SC kit for his E92 M3 from Active Autowerke, it was installed at our facility in August, 2010, mileage 24,345. In October, 2010; approximately 6-7 weeks after, we were informed that his engine blew . We immediately requested pictures of spark plugs, etc., and also to look at the ECU as this will also provide information on what went wrong; all were provided along with the request from Jordan to return the ECU to stock.

    Real evidence lies within the stored ‘Shadow Memory’ of the ECU. Active Autowerke never suggested that Jordan take his car to BMW to claim any kind of warranty, as we know it would be a useless claim because the shadow memory would be checked and the data would show cause of engine failure. Here were our findings when we viewed his ECU:

    The Maximum engine speed recorded indicated 8705+ RPM when the factory rev limiter is set to 8300, and Active Autowerke clearly set the rev limiter to 8100RPM for the supercharged cars.

    He was not at 6000 RPM when the engine failed.

    The throttle position showed 36% opening and not 100% opening when the engine failed, this would indicate that the engine most likely was in a deceleration mode. Active suspects a driver mis-shift going from 4th to 5th gear and hitting 3rd by mistake. Why? Because the road speed at the time with the 36% throttle opening indicated a 207 KM/hr speed (128 MPH). If the supercharger created excessive load on the engine to break the connecting rod, the shadow memory would most likely indicate that the throttle would be closer to 100% opening where the maximum supercharged power is developed.

    He claimed that his car was pushed on the dyno to 190+ MPH, the gearing on this vehicle makes it impossible for this to happen; it allows for maybe 183-185 MPH at 8150 RPM, this is the rev limit that was set by Active to the SC. In addition, Active Autowerke’s Mustang dyno does not allow for road speeds above 160 MPH.

    He said he drove the vehicle for only 1,200 miles, the recorded mileage in his ECU was 26,183 (42231 KM); therefore 26,183 less 24,345 = 1,838 miles driven after the SC install. If the SC system was the problem, damage should have occurred within 200 miles and not after 1,800 miles.

    All his spark plugs showed that the engine had no problems with any kind of improper tuning that would lead to “meltdown” due to lean mixtures or improper ignition timing, also, the pistons were not overheated due to ‘meltdown’, ‘meltdown’ is indicative of poor tuning, too low a fuel octane number, lean fuel mixtures..

    The engine connecting rod that failed clearly showed that it was still free to move on the crank pin journal, it was also free to move on the small end where it is attached to the piston; this was confirmed by Jordan when he was asked, his pictures also supported this. This verifies that lubrication was sufficient and the failure was not due to the connecting rod “seizing” against the crankshaft rod journal.

    There was no evidence of valves floating or broken due to contact with the piston of the damaged cylinder.

    In summary, E9X M3’s equipped with Active Autowerke’s Level 2 SC have run on the race tracks for driving and racing events, of which there has been no engine failures. Dan Schaut ran his 2008 BMW M3 equipped with the Active Autowerke Level 2 SC system in the 2011 One Lap of America event placing 1st in his class. In this race, cars are subjected to maximum use of power under the most rigorous condition for 7 consecutive days and covering over ~~4,000 miles of road and track. The E9X Active Autowerke supercharger system in Level 2 configuration has with stood the test of maximum reliability and at the same time delivering maximum performance under rigorous conditions and has shown that our SC system is well engineered and manufactured.

    In conclusion, Senior Technician, ‘Scrappy’ and Technical Director, Karl, in looking at the recorded data in the “Shadow Memory” of the engine’s ECU along with all of the stated observations, have concluded that the damage done to the engine was due to “driver’s error.”

    After no determination was shown for fault due to the SC system, an agreement was made for reimbursement for the cost of the system. Evidence of this reflected in the fact that both Import Motor Werks and Active Autowerke have mutually enjoyed a year of business relations. Recently Jordan emailed and demanded us to pay $25,000 or he would go to the forums. Although sympathetic to his loss as no one ever wants to ever have to pay for a broken motor, Active Autowerke cannot accept liability for damages it did not incur.

    Active Autowerke is a reputable BMW tuner and is now in its 31st year of business. We have sold innumerable forced inductions kits since 1995 and have always stood by our products.

    AA has always been a great company to deal with.
    Some people live long, meaningful lives.

    Other people eat shit and die.

    I'm not racist, I hate everybody equally; especially fat people.

    Checking the math Active is wrong here. The manual gearing allows for 205 mph in 6th gear at 8400 rpm. Even 8100 rpm is going to be enough for 190.

    What you guys say about the Mustang is likely true though.

    If you have this e-mail I would post it.

    Secondly, if you have proof of reimbursement I would post that as well as it would be proof of you have stated.

    I do not understand why he would e-mail and demand $25,000 after you already reimbursed him for the system. That was an amicable resolution.

    so, root cause of the mechanical failure is over-rev causing the rod to fail in tension or compression. correct?

    It would seem that way from the details on the ECU. Mechanical over rev due to a missed shift - no rev limiter can stop/prevent that - ie, the good 'ol MONEY SHIFT.

    Like I had said previously, now that both sides of the story have been stated, its a crappy situation none the less, but AA is a stand up company and a great family of guys that dedicate their passion to their customers and dealers.

    You will see more AA E9x M3's rolling out our shop soon enough!

    IMO? I think it's downshifting and bouncing off the limiter sharply (if that is what happened) that is worse than just the revs by themselves.

    BMW tested the motor to 10k rpm. There are people revving it to 8800.

    I don't like that they take the redline down, I wonder what their reasoning is.

    If you look at the piston travel and velocity compared to crank rotation at those revs you would be amazed. Every hundred rpms and the velocity and speed of the piston and rod is exponential. Just a few hundred revs can kill and engine easily....I think we've seen that lately with these motors. When you say BMW tested the motor to 10k, what do you mean ? How did they test it ? I find it hard to believe that this motor could live for any extended period of time at those speeds.

    Although not entirely relevant, I used to own a stage 3 AA E46 SC system for 2+ years and putting in under all kinds of abuse imaginable; street racing, road racing, drifting and some light drag racing, you name it and I've done it, and did it on a weekly basis.The ONLY mishap I've experienced was the meth tank (located at the trunk) came off under high G force conditions at the track with very tight corners; so the cause was 80% extreme driving condition and maybe 20% installation.AA's supercharger system had been rock solid based on my first-hand experience and they had ALWAYS been very easy to deal with.If I were ever to FI another NA BMW, AA will get my return business, and trust it will deliver the same level of satisfactions; simply don't care if others are advertising 100% more power.

    Once i downshifted a couple of gears and hit 8900. After that the engine started making a tlick tlick noise and the idle valve was damaged iirc. but that was it, no rod problem.

    Most of the time in a mechanical over rev situation the top end it the first to go as the valves cannot handle it and end up getting bent of not broken, and beats a hole in the piston, cylinder wall or lodges in the head. That may have been what happened here but with this amount of misinformation from the OP there's no way to tell and also it's pretty difficult to find out what actually broke first when you have a catastrophic engine failure like this.

    Definitely right and I think it was the bottom end that gave here.
