2.3 engine swap, methanol injection, wrap and new rims

It’s toasted for sure. It looks like a big section of piston chunked off above and below the ring which usually means the rings got heated up and expanded pushing against each other with no where to go. That ends up putting tremendous pressure on the piston and will break a chunk off.

It usually just chunks the top of the piston off because the lower half of the piston has a bunch more metal to push away from the rings. In this case it looks like the lower part of the piston got pushed away from the rings expanding as well since there’s not a lot of piston material above the lower ring and below the upper ring. Above the oil control ring as well. Pretty wicked.

This is what happened but it didnt take the top of the piston out and when disassembled the broken peices were within the rings in the bore. Ecoboost rotating assemblies are all forged, including the pistons. Im doing things the engineers just didnt plan for.

For sure. It’s very common on cars not build for forced induction and then someone throws a supercharger on it. The ring gap is set for NA for mileage and emissions and when it gets too hot pop goes the piston. Hemi 392’s are known for it.

Weirdly my last late model car was a Challenger with that motor. Being so limited in what I could do with it kind of killed the fun for me. So in a strange way the Mav is a much funner car for me even if the end result in my case is slower.

Hey Mike Check out JST performance, i think he's in NC, was very popular with the Focus ST/RS crowd, awesome reputation , was always a Tie between JST & Alan at Edge for best Focus Tuners but Alan is in CO

Really I’ve been in to and still am into focuses. Both those are good timers but I wouldn’t say they would even be considered the top tuners for them. Would have to be Livernois or Randy Robles. Tune plus has a big following but also a big horror story list.
He’s only a 9-10 drive from Livernois and has the tuner. Zero way would I buy another tuner to have it done. I just drove back from Nc last night. He will take not 3 tanks of gas to go up and back to have it on the dyno and done from Livernois.

I think ill be trailering it up there and back. Hate to think of what could happen when pushing the envelope on a dyno. Mabey I can get a tuned on the f250 6.2 gas while there.

Heck ya that’s the way to go. I also prefer to tow. Not because dyno is dangerous but better to have it tuned properly before a drive like that.

Let me know when it up. If you don’t mind I’d love to check it out. I’m 3 hours from them but work that way a decent amount.

Even "experienced" tuners of an engine/model can get bitten in the ass by that ring gap thing, because after 3 or 4 engines of "paying their dues" they figure they know enough now to "do it completely right with big money, dot every i, cross every t" and they might have had them die from other things, because they had well worn bores, leading them to think "stock ring gap is fine". So they get the ultimate motor, and maybe it's a fresh fresh block, or they get an 040 overbore, 040 pistons, 040 rings and fit them with the stock gap. Well guess what, no wear, no extra room. So get a couple of thousand miles on it and jam up the rings, where as mentioned various kinds of hilarity can ensue. However in modern motors, bore wear can be very very minimal with moly faced rings. I could still file my nails on the hone in a 250,000 mile motor I had the head off, and low modern ring tensions, due to thin rings, will not be sending it the other way any time soon.
