Let's hope your AA SC'ed M3 doesnt go boom because if it does the tuner will always find a way to blame it on you.
Or you can sell the car at the first indication of the ticking noise. Haha

I have no words for you sir.

I always ran 93 in Texas. It started to blow a lil bit of smoke when I gassed it. I think something was worn out already. When I first drove the car in SD it already started making a slight ticking noise (with the 93 gas in).

The guy has not pointed the finger at anyone. Let him tell his story in another thread. It is my understanding that he was noticing the engine acting differently prior to the 89/91 octane episode. It would be nice to hear a full story with an accurate description of what happened.

Sorry to hear the bad news. Things happen and we all have to learn from our mistakes no matter what caused the issue. Good luck with the rebuild.

I had bmw inspect the car when it was in Texas and they said everything was okay.

It was an abnormal ticking you could hear bouncing off walls or a sidewalk like some have described. I'm not blaming anyone or the kit.

When you ran anything under 93 octane, was it for a prolonged period of time? If you ran 91 octane and kept the car at extremely low RPM I dont think that would have caused the motor to pop - my buddy Salaccidentally threw 91 in his VT2-650 kit when he first had it installed and had to run the gas out by putting around at low rpm before he could get on it. His car is fine. If you hammered the car while consciously knowing that the car didnt have sufficient octane for its tune, well, thats an entirely different story.

h4nh,
I feel bad for you but no offense that was a pretty damn stupid move on your part. If the owner and manufacturer STRESS running 93 and not only do you use 91, but 89??? WTF!

Sorry if I sound harsh but you probably shouldn't drive an FI M3 to begin with


Enlighten me on why you put 89 in the car? Stupidity fascinates me. I'm not ESS or Biglare who sold you the car so I can tell you exactly what everyone is thinking...

Gentlemen lets all take a step back and not kick him while his down. Who really knows what happen to this engine. Yes, it could be a lot of things, wrong octane, preexisting rod bearing or valve defect exacerbated by a SC etc, etc. Ultimately his going to have to dig deep in his pockets to buy a new engine. I'm sure he posted here to blow off some steam and not to get grief from everybody. GL

His posting is a good lesson for people who supercharge their cars. It's pretty obvious that if you run 89 or 91 octane fuel in a supercharged car that requires 93 as a minimum you are going to damage the motor. I agree that kicking a guy when he is down is not cool but he is not going to get sympathy from anyone when he admits he put his motor at risk by not following the directions he was given.

The bright side is it is a killer car and maybe he can build the motor out so he can run higher HP safely

This makes me want to rethink purchasing a SC.


How many blown motors with SC'ers have been listed on this forum?

Most of the blown motor issues are from stock vehicles even 2009 and up have experienced issue from what I've read. From what I've seen the superchargers are not an issue, sure at higher miles one should consider mileage before supercharging/turbo on any vehicle.

That all depends on which company supercharged it

OP: Thank you for creating this thread!

Call me paranoid but after reading this thread it did raise some concerns for my 08... I remember hearing some abnormal ticking sounds just after my spark plugs were changed at 30K.. However it has since disappeared?..

At idle, the car makes all sorts of noises as Im sure all normal vehicles do... there is a slight ticking noise Im sure... but its not what the videos suggest (Random ; No rhythm)..

I am out of warranty... Should I be concerned?

I had the same concerns after the spark plug change hence the reason behind reviving the thread. But the ticking noise I heard have since disappeared and from the feedback from members who have listened to the YouTube video, all is well and healthy. Back to sleeping well again.

I'd suggest sending an oil sample off to Blackstone with your next oil change.

I was told from a very reliable source that the sky is falling.

Can anyone confirm this?

I hate seeing this.. Now I'm paranoid!! Fml!

Me Too! I looked out the window, and didn't *see* the sky falling.

...but like I said, a VERY reliable source told me it's happening. There's even a big thread on the Internet about it and like, 4 other people claim it happen too!

I assume that means I'm next.

How much does a S65 block cost? And where can it be bought from.

This is actually a great idea. We should probably ALL buy spare blocks just in case. Maybe ESS and AA should start packaging an extra with their S/C kits? The only issue for some is going to be storage.

Luckily, the bomb shelter I built for Y2K hasn't been getting much use. Well, of course, I stocked it back up for the end of the Mayan calendar, but that was a big disappointment too.

If anyone needs extra canned food - PM me.

Did you blow your motor?

It also depends on what the cause of the blown motor is.
