She Ded....rod through the block ded

[MurderedOutSVT]

sorry to have you join the club. my motor crapped out last month while driving on the highway. i didnt throw a rod, but my motor is definitely seized. just like you, no warnings, it just went

That made le laugh at mystory an

Well that sucks... How many miles did ya have on it with the Pro-Charger?
Unfortunately the weak link on the 6.2 is the pistons then the rods. Usually on boosted 6.2 the piston fails, gets cocked sideways in the bore causing rod failure and a nice window in the block.

If you need to do it on a really tight budget, find a good recycler and pull a newer SuperDuty 6.2. You will need to swap cams, intake and oil filter housing (SD is on the side) but everything else is the same.

Had no idea the 6.2s had weak rods. Going to b read up on that

I feel for you. I was in the same boat about a year ago. Just now financially recovering haha. The question now is go back with a stock longblock(heads are trashed most likely. Mine were) or going built and pulleying d

Sorry to hear that happened. Reminds me, if you'll indulge me, of my buddy and I in his 1968 Dodge Superbee, circa 1976, on our way home, drunk as skunks, from a visit to another buddy at SUNY Binghamton. Middle of the night, only car on the NYS Thruway and we hear a loud tapping coming from under the hood.

So what do we two drunk, stoned out hippies do? We light up a doob and turn up the music full blast. Few minutes later, like a loud pressure release, as pistons shot through oil pan and we come to a skidding stop on the shoulder. It was like 10 degrees and we were now freezing. No cell phones in the 70s, no nothing. We sit in the car deciding what to do. About an hour later a car pulls up. 3 big African American dudes in it. My buddy gets out. I could barely move. They said hop in, we'll take you to the next exit (which was like 25 miles away) and you can call a tow.

I figured he's history, I'll never see him again, they'll **** and simonize him. About an hour or more later the same damn car pulls back up. Not only did they take him to make a call at a pay phone(remember those?) but they drove him all the way back. He thanks them. I'm huddled freezing in the Superbee. He says "Tiny from the local gas station is on his way."

I'm tellin' ya, you can't make this sh i t up. I remember it like it was yesterday. It was 2 in the morning. After another hour or more a tow truck pulls up with a Gigantor, Hulk-like dude stepping out of it. That was Tiny. he hooks up the car, we jump in his cab. It was the bumpiest, noisest ride I'd ever taken. My head was pounding from about 20 beers.

We get to his station. We have zero dough. He takes the car in exchange for the tow.

My buddy's parents happened to be about an hour or so away in the Catskills (lovingly called the Jewish Alps back then) and they come and get us in the morning. We ruined the remainder of their weekend. We get back to the hotel which I believe was the Nevele, and we are starving and hungover. We need food. And money. There was a huge fountain in the lobby, like a wishing well, filled with rusty coins. We both lean in, grab as many coins as we can, go into the coffee shop, order sandwiches and drop wet, rusty coins on the counter.

Oh, did we have fun when we were young.

Thank you, i needed you story, and, no you could have made up

Iv'e had many high horse Fords, mostly 5.0 Foxbodies, several 5.8 F150's. First rod I have slung.

I'm not sure if 6.2 rods are all that weak. S.h.!.T just happens. I known guys don't take care of anything cars run like clockwork vs. Guys that are meticulous about servicing their cars and their stuff breaks.

Not as weak as lightning 5.4 rods. It cost ford 6 dollars per rod in the lightning 5.4s. 48 bucks per engine vs manley rods in the 03 4.6 cobra. That was 300+ dollars a set cost to ford. Anybody buying a performance vehicle would opt for stronger rods,bean counters always win and maximize profits.

Weak Rods is relative.. At 411HP stock they are just fine. When you start pushing 600 you are not far from the ceiling.... 750 is probably the limit.

Unfortunately the pistons are not super strong and have been known to fail in stock engines, so add boost = Heat & Preassure and you only need a bit of bad fuel to have them come apart.

I was fortunate with mine, it made 507 at the tire for 120,000 miles and is still going strong.

The one big problem unfortunately is the Procharger has spool up lag and it's something the software in the PCM cannot handle very well.
The same goes for the Whipple and Roush just nowhere near as bad, but the PCM has a difficult time with the By-pass valve and boost.
Ford engineers never intended running boosted application with the 6.2L so the software was never written nor are there chips and sensors for it like the Ecco boosts.

In your opinion, what issues arise from the PCM not handling the “spool up lag”?

As in what bad conditions does it cause in the cylinder?

Lean, very lean, that was Hennessy's problem, but they sold it anyway and many blow holes in the piston heads.
Destroyed Procharger's chance the be popular with Raptors.
Then Hennessy move to Roush units and it was "Flame On"

Livernois has a pretty good Tune for the Procharger but still, it's not their preferred application for the Raptor.

Interesting, at first blush I would have assumed it would be rich if the pcm is expecting more air than it is getting due to the lag.

Think it has to do with the ramp up of the boost?

 

[MTF]

Well that's just it, PCM has no clue what's coming.
Throttle and injector response comes from the trust values from the tranny but the power isn't there so the PCM holds off on AFRs and then the air comes now the PCM tries to make up for it.
