Land, Sea & Air
Whether you race cars, boats, or airplanes cryogenic processing can reduce the cost of your racing and help make sure you are running at the end of the race. Racing engines, transmissions, drive lines, suspension springs and more respond to cryogenic processing by improving performance, reliability, and durability. If you want to race for less money, you need to use cryogenic processing. Over 50% of the Sprint Cup racing teams do, and now many racing parts manufacturers are using Controlled Thermal Processing, Inc. to not only cryogenically treat their products, but to help them optimize the metallurgy of their parts.
Cryogenic processing is unique in that it reduces the cost of racing and makes the car more competitive at the same time. Many parts of the car respond to cryogenic processing. Cryogenic processing has been proven and continues to be proven race after race. Cryogenic processing allows a race team to win consistently, which is the key to winning championships.
Cryogenic processing has proven applications in every form of automotive, aircraft, and boat racing. Virtually any part that is stressed or worn during a race can benefit from cryogenic processing.
Increases Horsepower and/or Torque
Treating the block and piston rings helps assure better ring sealing, which raises torque and increases engine life by reducing wear on the cylinder bores. Treating the block also reduces distortion of the block during machining and running. Blocks should be treated after all heavy machining is done and before final boring and honing. It is beneficial to treat both aluminum and cast iron blocks. Sleeved blocks and cylinders (for instance, Harley Davidson cylinders) should also be treated.
Cryogenic Processing reduces wear in the valve train. This assures the valve timing remains constant. One of our pickiest engine building customers tells us his valve lash does not change during break in when he uses cryo 'd parts. Reed Cams agrees with him, as they offer cryogenic processing as an option on their camshafts and lifters. We see a lot less wear on solid lifters, and less breakage on roller lifters. Treatment of push rods changes the harmonics of their vibration, which helps prevent valve float. Our customers also report much longer rocker arm life. Treating the valves, guides, keepers, and retainers assures minimum wear in this area and minimum breakage, which results in reduced sticking and more accurate timing. Treating valve springs allows our customer much longer life. One Remax series racer changes springs once a year, where his competitors change theirs every other race. At $400.00 to buy a set of springs and $64.00 to cryo treat a set, you can see the economics. He consistently runs in the top ten.
Cryo Processing reduces wear and breakage of crankshafts. Two major racing crankshaft makers cryo treat their products as part of the production process. Cryo treating cast crankshafts greatly reduces wear and breakage. Cryo treating bearings helps to increase their life and reduce instances of cracking. Connecting rods respond to cryo by an increase in life and toughness. Dyer's Top Rods cryogenically treats all of its connecting rods and is known for having one of the toughest rods in the market. Pistons resist detonation longer when treated, and also distort less in use. Piston pins wear less. Piston rings seal better, vibrate less, and last longer.
Other Engine Parts
Timing gears, timing chains, distributor gears and shafts all benefit from cryogenic processing. Cylinder heads resist detonation better. Valve seats wear less. Water pumps last longer. A recent test on alternators revealed that we can gain efficiency and life on this part.
Any stressed part of a drive train will respond to cryogenic processing. All gears (Jerico Performance Products has all its shafts treated by Controlled Thermal.) Axles, ring and pinion, roller bearings, CV joints, and clutches all respond with beneficial affects of longer life and reduced breakage. One of our drag racing customers found both a longer clutch lining life and an increase in the coefficient of friction in cryogenically treated clutch parts. Their work was on an instrumented vehicle. Cryogenic processing is almost mandatory in tractor pulls and in drag racing of front wheel drive cars. A major European manufacturer of CV joints has confirmed through their research that there is a lot of life to be gained by cryogenic processing.
Suspension springs and torsion bars both gain in life and do not lose their spring constant when treated. Sway bars live longer and remain more constant. Treating A arms and other links helps control vibration. Treatment of ball joints increases their life. We have more than one customer interested in treating an entire chassis. Remember that the entire chassis acts like a spring. Vibration and flexing cause it to change it's spring characteristics and shape. Cryogenic Processing can help reduce these changes and also reduce the changes in handling that come with.
One of the most common parts of the chassis to treat is the brakes. Reduced wear allows our customers to get up to three times the life on their brake rotors. Greatly reduced warping and cracking is also a benefit.
What Should You Treat?
In November of 2001 Heat Treating Progress Magazine, the heat treating magazine for ASM International published an article by CTP's Rick Diekman and Roger Schiradelly on the uses of cryogenic processing in racing.
