"To finish first, one must
first finish!"
Professional and amateur race teams have found that cryogenic tempering
saves money and gives them a competitive edge.
Cryogenic tempering is changing the face of motorsports!
Virtually all engine parts respond to cryogenic treatment. Treated piston
rings seal better against treated cylinder walls reducing blow-by and increasing
horsepower. Cylinder blocks do not distort when subjected to the heat and vibration of
racing so cylinder bores stay straight and smooth. Aluminum pistons and cylinder heads
resist detonation longer. Crankshafts and connecting rods have longer service life without
breaking. Camshafts, bearings, timing gears, valves and valve springs, timing chains and
tappets all last significantly longer under severe conditions. Bottom line:
cryogenically-treated racing engines last three to five times longer.

The cryogenically processed piston has a more wear resistant
surface, higher yield and ultimate strength. This alloy will display structural, thermal
and metallurgical stability not found in the untreated condition, as well as significant
abrasive wear improvement. The contact and fretting fatigue will be reduced due to the
tightening of the surface microstructure. In addition, the corrosion resistance to hot
reactive gases and moisture in the combustion chamber will be improved. |
The same is true in driveline components. Bearings,
transmission and differential gears and cases, all respond to the process. And, clutch
disks and pressure plates are much less likely to warp after they have been treated.
