SC offering Cryo Treatment Service
Turbo Mini Forums

I've added a link to the info on our site. Essentially we are offering a pick up drop off service for gearboxes initially - other engine components can be catered for on request, blocks/cranks/pistons/rods/heads/cams/driveshafts/pot joints etc.

We will arrange courier pick up of the parts, treat them, then courier service them back to you - within 10 days for £280+vat

what you get to treat for this (minis only) -

gearbox casing/diff casing/end covers
all gears inc synco hubs
laygear + shaft
f/d gears
drop gears
selector forks etc

basically so long as the package weight is under 15kg total once its wrapped and packed.

- the box must be dismantled as the alloy goes through a seperate process to the steel
- all parts must be as spotless as possible as grease pays havoc on re-tempering messing the chambers up.

Any queries let me know

cheers

If Carling made Mini engines
it would probably be like this one!

ok

So that's why you sold your engine - good investment.

How is the dimensional stability of the treated item? Do we need to straighten things out afterwards?

Will you be able to offer the same service for crankshafts and rods? Does it have the same benefits?

Sorry for all the questions, but very interested for my next build.

PMSL @ joey!

John, what about if the ally has had helicoils put in? does this mean it then can't be treated?

excellent service johnny k
i love the LCB you do as well ... stainless

yes if you fell into the chamber it would hurt every so slightly- but only for a short while.lol!

- the facility isn't ours - I wish it was but the experience which goes behind the basics is huge way over 25 years of expericence in this field- I started talking with the guys when I knew what my next engine was going to be and what it had to withstand(this is where the investment went!)

yes cranks and rods/ flywheels etc can be treated using this method ( we are about to start offering cryo treated brake discs - the results from back to back tests look very encouraging for life expectancy and increased fade ressitance). Dimensional stability - I've had my block put through the process after it was "mid" way through machining. Post treatment any diffferences was not determinal by measuring before final hone/line bore etc. Same with the gearbox casing - no movement.

Small amounts of ferrous in the alloy wouldn't make any difference - its just large pieces like cranks/ally heads have to run seperately, I put a friends Saab Turbo gearbox through the process and it did release an outer bearing race - but this is a large piece compared to a helicoil, I think it was the post tempering process which did this rather than the cryo treatment, circa 140 deg C.

If we can keep our ickle motors + boxes in one piece under that little bit more pressure has to be a good thing.

great!

thanks for clearing that up John,

can you also clarify the pricing?

i would have expected the price to go by total size of the area of the chamber that they would occupy, you are stating a price upto 15kg, is that due to courier weight limits?

Steve, fitted one of those stainless lcb's yesterday, very very nice bits of kit, will post some pics tomorrow

JohnK,

Any idea how much extra torque a treated gearbox can take?

We generally reckon on 100 Lbft being the maximum for a well built helical gear setup. Roughly how much extra would you expect from this treatment?

mini13 - typically a gearbox (not including the diff lump) will be about 10-12kg) so our pricing is based on two things - the size of the gearbox itself - the larger the pieces the greater amount of nitrogen is need to cool and yes the courier weighting system. Hence we started with the gearbox first as its the weak link but we could arrange treatment of anything size wise up to v8 blocks etc.

Joe - good going!

Paul - that is a good question as nobody has done it yet for a mini. Lots of Saab and Nissan people have and going from feedback I've heard the difference should be pretty marked. One guy drag running a Sunny gtir broke gear sets frequently running 400bhp, post cryo treatment of the casing and gearset the car has completed over two seasons without a blip, similar story with the Saab boys, I think the testament to the process is that it is sanctioned in the US for motorsport use by the major bodies, in the UK lots of the superbike teams run the process on full engines as do touring cars etc. But when it comes down to the mini nobody has done it yet on a syncro box. I have on my box/casing but its a dog affair - so will see how that goes.

Cryo treatment really is the way forward, now get a ceramic coating service set up and your laughing!

Hi,
Would it be wise to do the transfer housing to match?
I take it this treatment isn't suitable for bearings?

Bat - works on bearings to!

Paul - yes or someone whom regularly throws gearsets out as service parts!!
