Can't this be determined quiet easily by doing a stress test?

 

I was hoping so, but I have been able to google any conclusive results. Im still reading up on alot of the theory behind the cryo treating, I like how it sounds, I just wanna find evidence to support it.

 

^ yah in my efforts to find a shop that did this I came upon lots of inconclusive evidence. But I also talked to several people who had ran 10 sec hatches on stock B-series trans and they kept breaking, then they cryo-ed almost every piece in the case except the case itself and it held a whole season. Granted talk is cheap but I am sure Cryo treating does work IMHO.

 

Write to myth busters

 

If professionals use Cryo treating, I'm sure it works (in some manner of speaking). I doubt they would waste time on a build to have their parts sent out to be cycled if they thought that cryo treatment wasn't working to their benefit.

Have you tried looking at WPC treatments, though? From the looks of it, you are planning on treating your engine and internals to make them stronger? WPC treating does make metal parts stronger, BUT it also reduces friction. The tests prove to reduce friction better than any of the best coatings available on the market right now (PC9, Molybdenum, etc..). The reduction in friction, on top of the strengthening properties are really what make WPC worth it (to me, that is). The only thing I'm not really sure about is the pricing..

I think a Mase turbo would be pretty sexy...! Good luck with your project, man!

 

So why aren't cylinder walls, bearings, etc being cryo'd?

 

Well, I'd assume you could cryo sleeves, and then have them installed, but if they are in the block then they would have to cryo the entire thing. My guess would be that it's expensive to treat something that large..

Bearings, pistons, etc COULD be done, but it all goes back to proving the treatment works.. I would personally go with the treatment that reduces friction for part like that.

I'm even planning to test a set of low compression CP pistons treated by WPC and using them with my stock FRM sleeves. Hopefully I can pull it off (until I save up enough money to get my spare block sleeve by Benson)! It just depends on how expensive WPC will be compared to just sleeving the block now..

 

Yes the WPC sounds good, what is it exactly? Also, some theory in cryo treating ferrous metals seems very promising, so how many people cryo the sleves? Is this common or not really necessary?

 

WPC is really the way to go when it comes to engine internals, differentials, and gearboxes. Friction reduction (increased life of the parts) and hardening properties.

From the website www.wpctreatment.com:

"What is WPC?


WPC is a proven process that has been utilized for many years in the racing and automotive industry. WPC is not a coating, it is a treatment that enhances the surface to reduce friction and strengthen engine parts.

WPC achieves this process by firing ultra fine particles towards the surface of a product at very high speeds. The resulting thermal discharge permanently changes the surface, strengthening the ionic structure and creating a harder more durable final product.

Why was WPC Developed?


The WPC process was first developed for the 24 hour Le Mans race. It was then introduced into Cart and other open wheel racing. The initial WPC concept has taken off and expanded into all aspects of motor sports. WPC has not only been limited to use in circuit racing, it has also found a strong foothold in the Drag and Rally racing industry as well.

Why is WPC Superior?


The WPC process is unrivalled in treating engine parts and other surfaces that have contact points of friction. WPC is superior because it is not a coating; it is a permanent surface treatment that reduces friction while strengthening the part. It's unique micro-dimple formation pattern greatly reduces friction and is unmatched by conventional methods of surface treatment.

WPC has the capacity to treat carburised, nitrated and plated parts without noticeable dimensional changes, and, upon completion of treatment, no further modifications are required of the parts. The strength and durability improvement on the surface after the WPC treatment is unsurpassed by any current methods.

Treatable products include steel, aluminum, titanium, copper and brass and soft surfaced bearings. WPC can treat any metallic item in a disassembled state."

I say check out the site, because I'm not really an expert on their treatment system. I just know that when race teams of that caliber use it and ask for complete confidentiality as to not be scrutinized by race inspectors for "cheating", there has to be SOMETHING there that makes it worth that kind of risk!!

In the mean time, I'm almost afraid to inquire with them how much it costs right now. I will eventually find out, but by then there will be no turning back for me, LOL.

"Frequently Asked Questions

Q.Will WPC Treatment change the dimensions of the parts I have treated?

A. No. The treatment doesnt add or remove material which would alter important clearances and tolerances for your parts. Strictly speaking there is a dimension change however the dimension change is almost undetectable. For example on a hardened surface such as on a crank shaft journal the dimension change will be +/- 0.00004 inches. On softer materials such as Piston Skirts and Bearings the maximum size of the dimples are less than 0.00008 inches.


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.


Q.Is the process done here in the U.S., or do I have to ship my parts to Japan?

A. WPC treatment is being done in the U.S now. We have been fully operational since Aug 2005. We promise a three day turnaround on all orders. (Some conditions apply)


Q. Do you have any minimum requirements for treating customer parts?

A. No. There is no minimum order required however we do offer discounts for people who send in more. Also we offer first time trial discounts and builder discounts to qualified builders as well."



Hope this gives you a little bit of insight on the subject.
