Quenching metal changes its properties, that's basically what freezing it is doing, making it harder. Harder as in more rigid. Other things happen but in general, a rigid part doesn't flex as much resulting in less heat (energy) from internal friction. Ever bend a piece of metal until it breaks and notice that the break is rather warm... energy.... connecting rods, blocks, cranks, pistons, they all do the same thing. I can see how a more rigid assembly would save a couple horsepower in that respect, NOT because it's slippy, that just doesn't make much sense. Keep in mind that a hard metal SEEMS slippery because it's so hard.

pretty much the right idea. ideally, you would want to heat the metal, freeze it, heat it again and freeze it again (heat treat). the goal is to increase the strength of the metal. in iron, for instance, you are trying to make as much carbon as possible because iron is a relatively soft metal. ideally, you would want to cool the metal as fast as you can, then hold it at a constant temp. this allows martensite (hardest phase of iron carbide) to form. however, this is extremely difficult to accomplish as the quenching must occur in an extremely small amount of time. |
an extension of the rockwell principle.
this is not to be confused with certain engine "coatings" which supposedly add to the ability of the oil to do its job correctly, which is to reduce friction. add in cryogenic technology with certain coatings, and the result is a stronger motor with reduced friction. i'd say that would be the equation quoted above, which would save HP and torque, but certainly not 'add' any to the engine.
if you do the research, look around, talk with other racers, there is a bunch of misinformation out there - 'specially on the internet. sift through the ******** to find out what the truth is, then spend your money more wisely. there are also a bunch of 'snake oil' salesmen out there, who claim certain things to be true but ends up with you just forking over tons of cash and them ending up with a fatter bank account - and no increase in HP or torque for you and your motor.
