Cryogenic Processing in Motorsport
We work confidentially with several professional and enthusiast car and bike race teams across the country (including Circuit racing, Rally, Hill climb, MX), helping them to both reduce team costs as well as improving performance.
Treated parts remain in an optimal condition for longer giving superior performance over an untreated part. Additionally the parts will require replacing much less frequently reducing service costs and frequency of failure.
Many parts are regulated or are mandatory so being able to improve the performance of that part will certainly give a competitive advantage.
For some teams we will treat the entire engine along with drive train components, for others we will treat just a few key items such as the camshaft and bearings.
Why use cryogenics?
Stability – ever wondered why you can get everything moving silky smooth on the bench but get wear spots when the engine has been running.
As engine components get to running temperature they are likely to distort, ever-so-slightly, causing those annoying little wear spots and small movements from when they are set when tuned. One of the main reasons is that when components are manufactured, stress is put into the item by the very method that makes them. It is this stress that causes the component to move, twist, distort as it gets to working temperature with in the engine.
The cryogenic process will dramatically reduce the amount of stored stress within a component by helping to form a unified bond between the crystals of the metal and so enabling the component to expand in a more uniform way as they reach their designed operating temperature.
The stress relieving properties of cryogenics work for both ferrous (by transforming austenite into martensite) and non-ferrous metals (by stabilising the crystaline structure previously set unevenly on fabrication).
Wear resistance – everyone knows that the continuous movement of metal against metal causes minute amounts of material to be removed. Over extended periods, over a race even, these small amounts add together to produce a significant loss of material and we all know the effects this has on performance.
Cryogenics will significantly reduce the amount of wear on a wide range on engine components giving the advantages of maintaining engine performance and reducing team running costs.
Most common items treated – Camshaft, brake discs, pistons & rings, bearings, valve springs, rocker pins, liners, gear sets, fly wheels.
