All drag racing teams know that the power that doesn’t last fails to ensure a trophy. They have learned a lesson the hard way how easily both money and win can be easily lost because of the thermal stress-related component failures. Now, thanks to the cryogenic processing, even a small investment can save literally thousands of dollars in replacement costs, not to mention all the lost races.
Drag racing pushes engine and all components to the very limits of durability.
The catch is to extend these limits in order to ensure better safety, more speed, and power. For these reasons cryogenic treatment has become an inseparable part of the drag racing industry. Cryogenic processing is much more than exposing the racing components to the extremely cold temperatures. We are talking about a strictly controlled process that provides permanent changes to the treated materials, which alter many of their wear and stress resistance characteristics.
How can drag racing benefits from cryogenic processing?
- Improved abrasion resistance
- Improved fatigue resistance
- Improved electrical conductivity
- Changes in vibrational damping
- Positive changes in heat transfer
- Stabilization of metals
- Reduction of warping
- Improved heat, stress, and vibration resistance
- Less taper
- Higher RPM
- Higher horsepower
- Longer engine life
- Less breakage
- Less vibration
- Lower cost of racing
- More trophies
According to experts, almost 3 out of 4 engine component failures occur as a result of the fatigue. Both engine builders and drag racing teams have begun to recognize the benefits of the cryogenic treatments that are increasing the dimensional stability, ensuring stress relief, and improving wear resistance. The durability is also one of the benefits. However, the drag racers put the strong emphasis on a hidden benefit – and that is more power. Less wear for drag racers means reduced friction.
When you reduce friction, you can expect higher torque and more horsepower. It may seem like a subtle difference, but when you deal with the wear resistance problem, then extra horsepower makes a difference between winning and losing a race. Professional drag racers see a huge benefit from cryogenic treatments. Above all, they can save a great deal of money because they won’t have to buy racing component and replace parts so often.
