I'm finally in the process of putting everything back together with my car, and I'm planning on getting my tranny built. I was considering Cryo or REM treatment, but then I heard about WPC Treatment. Any opinions on this? Here's an article about it in Turbo Mag: http://www.turbomagazine.com/tech/tu...reduction.html

Website for the company that performs the service: http://wpctreatment.com/index.htm

 

Gary just picked up components from there for our Time Attack tC

 

Well, that's all I needed to know! =p

 

interesting... price? The article states it isn't cheap

 

Around $4-500.

 

from the article it looks like it can be used on every internal engine component. and after looking at the price it isnt that bad when you compare it to shot peening. i might have to look into this a bit further, good find

 

It's a process that was talked about a few years ago. Seeing as it's in Turbo that would suggest it being a few years ago. I was reading on this but have had no practical experience. From what I read it was the newest thing to come out and be used in motorsports. Nascar was using these processes.

 

The NSX boards have some nice pics of parts before and after treated:

So normally, what parts of the tranny would go to get CRYO or REM treated? My power goals are around 700+

 

It's the best option for working with what you have.

The optimal option would be to have a straight cut dog box created. The stock gears physical size limit the amount of torque they can handle. Cases flex under that kind of stress pulling gear shafts out of line (thousandths) which change the gear contact pattern towards the ends of the gear teeth which puts extreme stress on the edges leading to cracking and ultimately shearing of a complete gear.

 

I only really here guys treating the gears, shafts, and bearings, but for a build with 700+hp, would that be enough?
