PIPE – A DELICATE MATTER

As you know, in most classes sports modeling the success of the competition partly depends on the power and reliability of microcomputers mounted on the engine. One of the most effective ways to increase the power of the motor is the use of exhaust energy through resonant pipes. They are widely .used by athletes to improve SSS-Rostik characteristics of models. The proposed materials are considered methods of calculation of length, volume, and other geometric parameters, allowing to improve the characteristics of the resonant pipes (at the end of the article, SPICON see references).
