Blown engine on 2015 ecoboost

yet another blown ecoboost engine. My buddy's 2015. He was running a turbo back exhaust, intercooler, intake and Lund tune. Cylinder 3 took a poop on him. He put everything back to stock and is now trying to find a dealer that will cover it under warranty.

I wonder what will happen with the Focus RS that has 350 HP. IDK if they've beefed up the engine more than the Stangs version.

V6 for 2nd place (we know who gets the win)

I think the ecoboost is a fine engine I just don't think Ford left as much HP on the table stock as some do.

Can we get the compression test results please? Not to be nit picky, but just coming in and saying a motor popped doesnt really help folks you know.

to say he should have just got the GT in the first place. I doubt the V6 is beefy enough on the bottom end to be subjected to high performance mods.

What exactly is your idea and definition of high performance mods because there are boosted V6 Mustangs out there. A 3.7's engine can easily and safely handle 450 to 500 rwhp on factory internals. Is that high performance mods, SC 10 pounds boost.

Just a near stock 3.7

I don'y know the answer to that, referring to what might be too much as far as performance mods are concerned. I do know they're blowing up. The GT has the power and torque that some are trying to get with whatever mods they're employing. As far as 6-bolt mains go, the journals may not be beefy enough--regardless of how many bolts connect the main bearing caps.

Same here, all 4 bangers are rice cookers, regardless of power. V8 or nothing you feel me?

That doesn't really mean anything. Manufacturers don't make costly design decisions unless it is required to meet there design goals and the 3.7 was never designed for performance applications. The fact that they have a 6 bolt mains in the engine is an indication that they are shoring up a weakness in the block or crank.

A Mopar small block with 2 bolt mains and a cast crank is stronger than a Chevy small block with 4 bolt mains and a forged crank is a perfect example of the number of main bolts doesn't mean the engine is string.

Can you explain the meaning of the bolts if you don't mind?

I do feel you if I can't have a V8 performance car I don't want one. I'd stick with my Jeep and play with that.

Whatever it is that is causing these engines to blow, man. Maybe the tensil strength of the bottom end is not strong enough to handle the heat and pressures created by whatever "mods" one is using. I don't think I actually said "beefy V6 performance mods," but if i did use that actual phrase, I can see why you might be confused. The b bottom end may not be beefy enough to handle the performance mods people are using.

Four bolts are bolted vertically and two are bolted horizontally. Never heard of a 3.7 blowing the bottom end! For the STI, you can have it and the bus to go with it. It's just butt ugly. Sorry but
I have a right to my opinion!
