M3 engine with Active Autowerke supercharger kit exploded (allgedly)?!?

[Kyoshi71]

Where's the connecting rod? First stab in the dark would be detonation. A knock is not just a knock with FI.

[per]

Doesn´t the active SC use meth? in that case there may be some stop in the flow,this could easily cause a failure like this.
Does anyone know what sort of safety system the active are using to prevent failures caused of stop in meth flow,safety valve that would reduce boost or anything else?

[zhangzeyuandss]

wow the repair is going to be expensive....I was told they are still trying to go back stock and do a warranty repair from BMW

[Dave07997S]

I understand that the SC may not be the cause of this major malfunction...however, it is a force multiplier. A hiccup in fuel supply, bad fuel or spark where there is a misfire or such and disaster can occur.

I may get flamed for this but here goes...if you wanted a SC'd car you should have bought one from the factory. Cars like the Mustang Shelby GT500, the AMG cars etc. from the factory are built for the rigours of SCing. Lower compression, forged bottom end and a hose of other enhancements that are meant to keep the engine alive during boost.

I am in no way disrespecting AA, Gintani or anyone else that has a blower kit out there for the M3, but if you blow up while you are SCd how in the heck would you expect the manafacturer to warranty the car.

Now I know a few of you guys that are running blowers are going to come on here and tell me that I am full of it, I understand. However, if and when a similar thing happens (I hope it doesn't) please remember this post.

The whole point of the M3 is a high revving normally aspirated powerplant. I feel that people who want to run a hairdryer or a huffer bought the wrong car.

ding, ding, ding we have a winner.

An amusing story..when I had my 04 E46 M3 some guy in a S2000 wanted to run me as we were getting on a freeway entrance (btw, I don't condone street racing) and I bit and we were off...all of a sudded from behind me I hear this BANG!! The guys S2000 hood flew off. So I get off the next exit, back track to see if he's alright...turns out he had a nitrous back fire (he was running a 150shot) blew the top of his intake manifold off and it took the hood with it. He was OK, but he was a young kid who kept muttering how his mom and dad were going to kill him because he didn't have the money to fix it.

What would cause you to throw a rod/piston ?

[WillC310]

WTF is going on here? The original thread was shutdown on ziptied, then there was another thread on e46fanatics today talking about the same thing but now that's gone too.

[Green///Hell]

Shady, if anything the threads shouldn't go away so easily. But cash runs everything I guess

[FStop7]

Looks like detonation to me.

So now the question is was it a defect in the motor, an issue with fuel delivery, or a tuning problem?

[mkPOTO]

Holy shit that's crazy

[iveman89]

wow if these guys win their claim against BMW, I would be amazed!! Have there been any other blown motors without superchargers? Even if it was BMW's fault due to a defective piece, if the only way to blow it was to put on a SC and increase power over oem standards that really isnt their problem right? good luck with that argument!

Yikes. http://www.ziptied.com/forums/index.php?topic=34449.45

That's why all the threads are being closed. Someone finally woke up and remembered BMW does check forums.

we will see how long this thread last

Someone a few months ago here said that running Meth would result in blown engines. Can't remember who it was though.

[m33]

BMW check's the forums for sure and this thread is killing any chance the owner getting his car warranted .
I would like to see how Active Auto plays this out !

[satinghostrider]

I have been through a similar thing with my car and I can tell you the 08 M3s and earlier are not advisable to be supercharged. At least for me, the main bearings pre 10/2008 were quite notorious. BMW changed the bearings after 10/2008 as a result. Hell could be a change of supplier like what some people mentioned but I think not. Even 1-2 guys with 2009 cars had some bearing issues. I don't know if it is the cause for this particular case but I believe that the M3 has a problem with insufficient lubrication. Couple this with bad bearings with an FI KIT, you have a ticking time bomb.

Completely agree with you on this. +1

Someone should tell the N54 guys, because almost all of them are running it.

Willing to bet it nothing to do with the failure.

i hope they win, just for laffs

You'd have to still believe in Santa Claus to think you could fool BMW that the blown engine was stock. I've come across a lot of (mostly rich) people who genuinely think everybody else is stupid. That guy, thread deleted or not, is f***ed.

[satinghostrider]

Anyone noticed the HKS R spark plugs? I thought the stock ones were NGK R. You do know the S65 uses the spark plugs as ionic sensors to detect knocking and the S65 does not have an independent knock control system. I have been advised by some tuners that the ECU is written in such a way that it works properly with ONLY the stock plugs. It's quite hard to say if this could be also the reason. But it should be considered as one of the probabilities together with some of the weaknesses of this particular engine blown.

[BMRLVR]

Methanol injection is a band-aid fix to a poorly engineered kit. If ESS can make their systems work without methanol why can't the competition.

Look at those plugs...... They were running extremely lean..... The kit was definitely a contributing factor to this failure. Anyone who thinks different is not all there. AFR's, IAT's and combustion temperatures need to be controlled very closely on an FI system being installed on an engine running 12:1 Compression. Methanol injection is not reliable enough to control this on a street driven car. On a race car methanol is good for squeezing out the last few HP but on a street car it is not ideal.
