Hi,

That's not to technical. we do sonic testing at our shop as part of qualifing parts.
Thanks for looking up the address.
Iam thinking of sending my spare motor out to get it treated. our new motor was treated and it has show a major increase in HP,Torque. (well major for a KT100). along with our rear disk brake, and rear hubs.

Default Cryo-work

TIm,

My borther and I have been cryogenically freezing parts on our karts for years and use a place only about 20 minutes away from here. He is a Kart racer himself and runs 125cc Shifter class.
Give me or my brother Pierre a call at work and well talk to you about the cryo work. He does one run a week and takes about a a week to get your stuff back.

TURN YOUR PHONE ON!!!!!!!!!!! all I get is a recorded voice message and then it hangs up on me.

Good Luck on Saturday..remmember Fast is Slow..... (quoting Jacky Steward). also look for the new Red fronts we talked about.
run them batteries twice a day if need be you can charge up to 7 amps (more punch/less run time). and stay smooth.
I will call you on your cell on Saturday

ok I need some help......... I an looking for a place the does cryogenics to do some small parts (Clutch bushings and other misc things). since there is nothing in Mi I was hoping to find someone who knows a place where I can send these parts.

Thanks in advance

Tim

wow that red looks pimp...... black anodising would make that killer... i run for a pan car company and we did a few prototypes in red grafite with black anodising and it was killer...

dye those white ball cups ha ha.. go to a super market and get some rit clothing dye... i dyed my white cups to a perfect match with the red grafite it looked sweet....



we were going to do gold grafite with green anodising for that bling look.. but we thought it was a bit to guetto ha ha ,...

Uh, not to burst a bubble, but I'm a mechanical engineer at a Masters level with minor in metalurgy. I've read a few papers on cryo treating brake rotors and other parts for increased life etc...

Bottom line is there is no measureable impact on metalurgical performance of the parts after cryo treating them. There is no change in microstructure that would improve the performance. All studies to the contrary are of low sample size and not exactly of the scientific methods. Any improvements in performance are most likely perceptual and along the lines of the placebo effect.

Specifically, the metal does not go through a phase change to re-align the microstructre during the cooling or heating process.

Probably (speculation here...) the only impact you can make is the thermally induced stress gradients across the thickness of the parts. All this really does it work harden them. If at all or enough to matter.

This sounds like techno babble - but trust me. Cryo doesn't do d|ck. There is a reason you don't hear about everybody doing this stuff in major race classes. (shifters don't fall into that catagory, sorry)

Annodizing is another thing entirely....

Anyone wondered if BMI's nerf wings are worth the extra money? THEY ARE!!

That saved the wishbone and anything else on that corner, and the car finished the final easily. didnt even realise it had happened until an hour ago when i started to strip the car for a rebuild

burbs,

I don"t know about a gold chassis with all the aluminum anodized in green,that would definately look unique,but thats what is cool about this hobby averyone personalizes their cars to look good to their own eyes.I was thinking of anodizing everything gold to match the red chassis but i"m still debating that,as far as the white ball cups go,thats just what I prefer,I think it looks good with any car.

Scott
