What have you done to your Ecoboosted vehicle today?

[irondoor19]

Start of pulling the 2011 Motor Apart...

Looking to be a Nightmare as lots of Metal in the Pan

[SHOdded]

Will be interesting to confirm where that metal came from ...

We will be pulling off the Head Today, AND
will up date the progress as we Go..

picking up a Brand New Motor Today as well...

[irondoor19]

Yep:

As bad as it could be:

Hole in the Piston, Thanks Pickups Plus Cars,
AND me for breaking everything I touch.....

and Further to the Saga, Melted Right Thru:
Anyone Done this Before..Sort of Impressive

[SHOdded]

Surface rust.

[irondoor19]

Yea, we have been busy Today.....AND

Things are always darkest before the dawn,

So It is dawn again, The New Motor has arrived

[SHOdded]

Wow, must be nice to hold it, hug it, squeeze it ...

[FearlessAZ]

Needs more boost

I think that's NOT a melt,  that's a ring-gap collapse!  i'm about 95% sure of it... look at the side of the piston in pic#1 (top) it is protruding up...

NOS?  or really high boost ?

[irondoor19]

Yea:

We think Rings too, Turbos Went at the Same Time Tho,

So a bunch of Crazy Stuff at the same time.. TOO MUCH Boost

And how much was too much in your case? Did the turbos somehow cause an overboost situation when this happened or commanded boost made it go pop?

hmmm .. what kind of damage was done to the turbos?   they are upstream... other than a backfire with enough force to offset the incoming stream of air they should survive the rings closing/collapsing then the piston cracking and then exploding upward and inwward.  all the damage should be central to the combustion chamber, heads, connecting rods and inner block.  chunks noramlly would not make it back out past all intake bends..

AJP might have a batter answer as to pressure limits.  but what causes rings to collapse is heat.  hotter they get the closer the gap becomes to closed.   once the gap is closed all they can do is collapse upward or inward.  this ring collapse causes the ring ends to overlap, this overlap then fractures the piston since the piston sleeve can take it and redirects the force of the overlap back onto the piston

this is SUPER common among NOS users running NOS on unprepped blocks where the OEM piston ring gap is unmodified.  for NOS you end up filing the rings open a bit more to prevent this or buying pregapped NOS rings based on the shot of NOS your going to do.

this is a bit over dramatic but a excellent example : https://www.youtube.com/watch?v=AScojLj139A

15:15 to skip straight to the carnage of 300 NOS shot .. but the whole video is fun and informational .. actually the whole series is.

UPDATE:

Shot a video and posted it on YouTube.  I feel like a pro now
Here's my Livernois downpipe with OEM muffler.  Sound is a little noticeable at start up with a low-tone rumbling but when you drive it, it remains quiet as it was with stock.  You do notice it the downpipes when you punch the gas pedal.  I'll try to post video of that a later date.

Installed an RX catch can today. Nice spot next to CAI. Had them add some extra hose since most install on other side. Will do a full write up soon.
