Some of my SR20 peeps are breaking transmissions when drag racing with drag radials. Does anyone know of anyone that cryo treats large object like entire transmissions? I think I've heard of engine blocks being treated, so it shouldn't be impossible.

 

sure you can cryo-treat 'em. Whats breaking? gears? cases? output shafts? diffs?

I've never had a problem personally. For some reason, transmission cases on B13/14 (91-99 Sentra/NX2000) Nissans crack when drag radials are used. Even if solid motor mounts are used.

Sounds like maybe solid motor mounts would only increase the likelyhood that it cracks - if a solid mount is in place its transmitting force/vibration rather than absorbing it. I would think that cryo treating would definately help these cases stay together, i gather that this is a stress failure. Its not that expensive ($600 or so for an engine block, IIRC), especially if it keeps you from cracking tranny cases and/or shredding gears because of it. Where do the failures occur? I would guess radially across the bellhousing (i.e. across the case from front to back of the engine bay).

That sounds right. Like I said I haven't had any problems. Oddly, it only happens when using drag radials.

I suppose one solution is they could stop drag racing the darn thing....

 

Yeah but its more interesting when you keep breaking stuff

He does it all

 

Thanks Elyse!!

 

You could also drop Bowie a line. I know he sends stuff to the nascar shops in Charlotte to get dipped along with their "big" stuff. Give him a call and ask what his connection is.
