WPCtreatment

[4sfed]

So...based on the revelation of what bpd1511 is doing to his PTU....I have a thought (which I'm REALLY thinking about pulling the trigger on).

Buy a new PTU (which I've seen new for about 650-ish), disassemble it for the wpc treatment. Then swap it in and sell the old one on eBay. Or wpc treatment the old one and keep it for a spare.

The only thing stopping me right now besides the cost, is....will the wpc treatment ACTUALLY help the PTU durability/longevity.

Is there any way to measure the wpc treatment "effect" on the PTU? ...other than the PTU not blowing apart?

Really anxious to hear how this works out for bpd1511

Thoughts?

Machine shop that tore down my motor, forensically analyzed it, and recommend all the things they are..... swears by the WPC Treatment.

Expounding that the foreign model owners have been using it for years.

Shop said it absolutely will make a drastic difference/improvement.

I'm just as anxious to find out myself.

I would think oil analyses would be helpful. Of course, taking abrand-new one and running it for a year, with oil changes over time, and then a WPC-treated one for a year so you could compare would be a tremendous effort.

You'd have to get a bunch of people together, and get them all to do oil analyses and watch the degradation over time

TBH, I think there's something fundamentally out of whack with quality control when it comes to these things. The "reverse ring and pinion" (as I call it) that sends power to the driveshaft is the most suspect. I'd love to see a contact pattern of a few new ones to see what it looks like.

Somebody make us a billet case and that will fix most of the problem at high hp...

...using mainly spoons and some 2x4s, we've managed to bolster the PTU's durability by 0.07%

While I'm still anxious to hear your results, I don't this is something you'll feel; more like something you'll know after 1,000 passes at the track.

However with THAT said, if the import group have been successfully using it, and it has proven results....that might just be good enough for me!

Reading more details on their site;

"Q .Does WPC Treatment improve the strength of parts as well, or is it just for friction?
A. Yes. WPC acts in two ways to strengthen parts. First it adds an extremely high level of compressive stress at and near the surface. The second point is that WPC Treatment creates a Nano - Crystalline structure at the surface of the metal. Both of these mean that metal fatigue and crack initiation are both noticeably reduced."

Does this mean that it could strengthen the case, even though there's no friction points, just by applying the treatment to the outside (and maybe inside as well), of the case?

Too many questions!!!!!

Strike my last! Their site states that they do the treatment to headers, to prevent cracking at the weld zones. So it's a "yes" to my question.

The issue is case flex which will cause gear clearances to open and then the gears fail.

Anybody have any idea on cost to have said treatment performed on an item such as a PTU case and related internal components???

Also, with a nice deep pan and external cooler. Looking at you Gearhead???

 

[bpd1151]

I'll find out at some point when mine's ready to be sent off along with all the internal components.

I'll re-post when I find out.

Although my block has yet to return from the close decking work. So it might be a bit.

Too may irons in the fire at the moment. Not my forte but someone with the capability could make a good profit with these things....

An external oil reservoir would probably be easier to make. Two lines, one in the drain plug, one in the fill plug, probably enough movement in the oil to keep it circulating. Where to put it would be the question

 

[Zpak]

I’ve thought the same thing, but there lies the question, movement of the fluid, would it circulate? Wouldn’t do you any good if it just sat there.

That's why I'd have to check what's possible. A small tube on the end of the drain fitting, with the end cut at an angle, facing a gear that's pushing fluid might do it. Lots of possibilities.

On the other hand, I think changing the fluid often and using a really good fluid would be just as good.

Yes please!

I emailed him and he's like an exploded view diagram, to give me an idea of what he could treat and how much it would cost. And I can't find one for the LIFE of me. So anxious to hear the price range.

Has anyone seen the demo videos on their site? They are INCREDIBLE! I highly recommend checking them out. Makes me want to have my engine done as well.

So how much flex are we talking?

Would something like a strap around the thing (like a blower strap or a tie down), keep the flex down?

No just needs more rigidity. Just think about how another 5-10 thousandths of an inch extra clearance (backlash) can affect the strength of a gear. You end up with all the load being on the end of the teeth vs deeper in the gear. That's what breaks them. When the case deflects just a little bit, the backlash of the gears increases.
