Cryo'd Input Shaft

[Octafish]

Has anyone cryo'd their input shaft?

I'm sure this is a cheaper alternative to billet but someone mentioned it and I'm curious.

If my thinking is correct, cryoding things make it stronger on the surface not internally. So like wear parts such as crank,  cam, even pistons will probably double the lifetime. Metal itself is only as strong as what it's made out of and the process of how It's made. 

Someone school me on this

I think its more fun to watch you eat popcorn. 

 

@Octafish I cant add anything to cryo stuff.

If I remember right from metallurgy u are correct

How about Looking at the final ratio? Tires sizes? 

 

So far I've got close to 378k miles and never broke a input shaft on NV4500. This is strictly because my final ratio has either been 3.55 or now 3.69 which takes the stress off the shaft then being I'm running 245's now the tire gladly break lose before the input shaft does. Now with my economy tune and the fuel map its limited to 30 PSI of boost which is fine.  Still running the OEM input shaft.

 

Even better yet never had a 5th gear nut issue either.

 

Now what I have broken was my main shaft.

I went with both billet input and intermediate shafts on my rebuild and can confirm that they are ridiculously expensive.  If I remember correctly about $600-700 each.  Only reason I didn't do the output shaft is because it can be changed without removing the entire tranny...and of course I didn't feel like shelling out another $600-700.

I think the base material becomes stronger because the molecules line up throughout. Or at least I think that's the thought process behind the deep freeze

Has to do with grain structure

 

[Evan]

Yes instead of spurratic structure it's more composed and lined up. Is it woth it? I dunno I have  chryoed rife barrel I think I could have put that 100 $ to use somewhere else
