Cryogenic Hardening ?

[B-Man]

Hi,

Has anyone done this cryogenic hardening on any engine components - I have just been reading an article on it in an old Zoom - The theory makes sence, but I understand it is still relatively new in Aus. The mention a mob in Revesby that does it - Cryotuff or something ??

Calling out for any real life experiences as I am 'thinking' of doing this to some of my engine bits during the rebuild process.

I spose the bits to do are : Block, Crank, Valves, Springs, Rods, Bolts - (assume forges pistons don't need it)

Thanks in advance.

The article in zoom was pretty good, i guess the only info you are missing is performance increases on a similar engine. I'd suggest its minimal, but in terms of a high end engine it would be worth wile, and a race car would be noticable because every small bit counts.

Brendan,

Look it up in google - lots of articles.

I am doing most of my motor (ie. pistons, rings, head, valves, crank, rods, maybe even block, cams).

LSW in Revesby charge $80 min. for 16kg - can't hurt

Tony, are you just going Cryotuff or do you linish aswell ?? FIIK ???

It certainly sounds good.

I'll take a look on google - Actually I did, but it didn't turn up much - but I'll try again.

What components are you getting done ???

Crank

Block

Cams

Valves & Springs

Head

Rods & Bolts ?

What about bearings ??

And what about the new bits you buy ?? Do you do these too or not neccessary ???

Tony, I reckon I am going Arias Forged and Eagle Rods, maybe Carillos. I wanna build it tuff and strong cause I wanna hang onto the car for a fair bit longer.

Try this:

On some components it doesn't do all that much - but it certainly does not hurt. Obviously parts under low stress do not benefit.

It seems to be that you can do them on new or used bits. They said it would be no problem treating the existing crank, cams.

For the money, it's a bargain.
