Questions?? Anybody Cryo An Rc Engine Before?

I come from the world of motorsport's and we Cryogenicly treat a lot of high wear items on our race cars, brake rotors/pads, diff/trans, motor internals etc. and the results are amazing. Im curious if anyone has done this to an rc motor? I would think it might help with the longevity of the motor, keeping everything nice and tight for a longer period of time. I was going to try it on my next rc motor but was curious if anyone else had tried it with good results?

interesting , i have heard of it but not sure how it would work on a plated surface such as the a/b/c p/s system we use in our engines
would def. work on the crank

i am interested , whats the temp you guys go down to for steel ? aluminum?

Around -300 deg F? Pretty damn cold...

Do you cycle cold to hot, cold to hot? Or just go from cold to room temp?

The closest thing to it. http://z-carstore.com//catalog/produ...products_id=42 The ceramic coating of the piston has many benefits.
1 The friction coefficient between ceramic and the cylinder wall is WAY less than bare aluminum
2 The engine lasts 10 gallons+
3 It absolutely hauls ass
4 It revs really fast and sounds different most say

I thought that ceramic coatings inside the engine were illegal for racing.

I have a friend who has been doing this to his engines for years. He says his internals last a lot longer. I have not tried it yet.

would be nice to know what parts being cry'od would be beneficial and what would be harmful , what temps to go too , how long , so many things to try

Could you find out what temperature he is doing it at? I plan on trying it for my next motor to see if i can squeeze more life out of it. I plan on doing the rod, piston, sleeve and crank.

From what I've heard (a good friend of mine works with metallurgy in motorsports for a big company overseas) it takes quite a bit of skill and process to get cryo treating just right. If you do it wrong you make the part very brittle or cause internal cracks to start.

I'd just call up a company that specializes in treating parts like that. I have heard of folks racing using Diversified Cryogenics for some parts, not to mention they sell their own line of brake rotors which I ran on my last car.

you must be careful as cryoing items with more than 1 material integrated usually creates problems .
