bpd1151's 2010 SHO Rebuild Thread.....

[bpd1151]

@shoblock..... Since this question was posted during off business hours, I had to obviously wait in order to present your question to the machine shop performing the work. That said, his reply is posted below:

"Every production head and intake manifold is sand casted. So you always run the risk of thinning the walls. But to insure we don't thin them to much, the manifold and head get pressure checked to roughly 60psi which is over 3 times normal pressure, in order to assure no leakage and that a sectional area is not to thin. Also thats why I do a test port to get my data and flow test it (and pressure check it to) to assure we have no issues before I do all the other ports."

Hopefully that answers your question there shoblock.

I personally was happy to not only have recv'd such a quick reply from the shop, but more importantly, also happy for you having presented the question that you did.

My own head's on a swivel as I find myself learning more and more with this latest re-build.

Hope everyone has a great Thanksgiving!

It definitely sounds like you’re in good hands over there. The thing will be a beast man.

The car will die one day, but this engine will be passed down for generations.

I took a walk out to the line to look at head assembly. There is indeed a great deal of opportunity to smooth out the rough surfaces in the ports. Even if you don’t open them up by removing material, shining the surface by smoothing them out with a rotary sander will absolutely buy more horsepower as the air will have a less restricted flow when you’re finished. One analogy would be to think of bowling lane coated with sandpaper instead of waxed hardwood.

Happy Thanksgiving to you. Keep sending the updates. Its a fascinating saga.

Reached out to the machine shop today inquiring about any progress/updates.

Figured it'd be slow given the recent holiday, and likely will continue to be slow given Christmas and New Year's is quickly approaching.

I did hear from the body shop however and apparently the (several years) old 3M paint protection film was a real bitch to remove. Took nearly a full day to do so. They also stated it peeled all the paint off. Yikes! Which was/is fine, cuz it's getting entirely re-worked/re-painted anyhow for anticipated mounting of the custom splitter. But yea, I'm not even sure if any of that product was designed to be removed anyhow.

She's being prepped for priming now.

I also will be going with an entirely new product, which is a ceramic film called "Xpel Ultimate Plus". Guaranteed to never fade/discolor for the life of the film, and also is designed in some chemical/molecular way, in order to allow removal (w/o any damage to underlying paint) if it should ever be necessary to do so.

A picture of the pamphlet is displayed. Feel free to visit their website for details.

Hope to have more (engine) **** pics for the community soon. Hope everyone's well.

Good stuff Mike.

Chicago is a difficult environment for paint protection products, just like Arizona is. Looking forward to the new paint/film, should be a stunner

Arizona is brutal because of the dirt and blowing sand. It gets into everything. I need to get off my butt and re ceramic coat my SHO.

Bpd1151, will you hit up any car meets when it's done.. I've gotta see this thing in person and pick your brain. I'm a 2015 non pp sho owner, very interested in the ptu work your having done!!

Direct power does not **** the PTU's. It is lack of maintenance. BPD is a very special case because of the amount of HP/TQ he will be running. 99% of SHO owners will probably never see 60% of his power output, thus going over board on a PTU is just wasting your money.

Of course I will be. Gotta add to all the awards and plaques in the garage already on display after all.

I would disagree with this statement, mine blew up at 80k KM and I was religious with maintenance on my SHO. I could have possibly had a bad PTU, my SHO was not even close to Mike’s SHO in terms of power. I didn’t drive the car hard necessarily, but I did take it to the track a few times

You can disagree, but you are wrong. My PTU is golden. Well maintained, and thrashed every single time the car get put into service. I seeing as many street light to street light grand prix meeting as I can, it has over 50 dyno pulls, and over 50 passes at the track all in an extreme climate. 75K on the ticker. My transmission failed at 69k with zero issues ever with my PTU. Also my car is literally a 400/500 power car as well.

"PTU's don't fail at least not from a power handling perspective. These only fail from lack of maintenance. Spun bearings and galling of the gears from lack of lubrication.

High Heat dries up the lighter oil molecules in the ****, which causes more heat due to lack of lubrication (thermal runaway) which leads to the remaining gear oil turning to thick black paste which clogs up the vent tube in the ptu which cause pressure buildup in the ptu which forces the remaining, non-congealed fluid out past the shaft seals. Now the only left is a thick paste thats easily flung off of the gears, sticking only to the case. After this chain of events, the bearings run dry and begin to fail, next are the gears. Tolerances widen or things begin to sieze. Bearing and gear noise are usually the first signs of mechanical failure.

But the PTU internals are stout. The weakest part of our powertrain is the RDU Atc coupler. (The electronic coupler in the rear differential). At least in terms of tq capacity and power handling."


EDIT: I give credit to Mr.highcaliber for that bold information. I didn't relize that when I posted I didn't give him credit. My apologies.

 

[mrhighcaliber]

I run my sho the same way. Beat on it every time time I drive it, countless street races, track passes, 50+gallons of meth sprayed, and just hoonin' all the time. And I don't think I'm too far off from your power figures right now. No ptu issues. Ptu Oil is still clear as when I put it in 25k miles ago. 129xxx odo. Running Amsoil Severe gear.




The ptu is not scheduled maintenance. Ford says it's sealed for life and even if you ask them directly to change the ptu oil, most dealership techs will respond with " it doesn't require changing, it's sealed for life". That's what the service computer says, so that's how they respond. Which is probably why yours failed in 50k, Which is right about where quite a few fail.

I am actually really interested to see how BPD is going to answer the transmission riddle.

Still have no answers, although oddly enough, I too am curious what's going on with it, so I had asked my own mechanic friend the other day for an update (and again, just odd timing) but he replied today he was going to reach out to the vendor the trans was sent to, and ask for any details/updates.

Until then, I am as much in the dark as the rest of of you.

I'll post when I learn anything.

CUSTOM EXHAUST MANIFOLDS!

Jigs are being set up now, and exhaust manifolds are being prepped to be all cut up and rebuilt from scratch. All by hand!

Machine shop owner stated that he can, and I quote "most definitely can make more in the future". So good news on that front for those of you interested in investing in a future mod. No price point obviously, as it is way to early in the game for that, and no, I am not disclosing what the estimate is for me alone. Sorry. But not really. LOL.

For reference, 1/2" thick steel as support and a 3/4" inch thick base plate. Nice!!!!

So it's my understanding that these manifolds are really a manifold in a manifold...for heat protection purposes. Will they be doing something like that, or something more along the lines of shorty headers...
