supramkivcork Posted March 30, 2010 Share Posted March 30, 2010 New NCT Requirements : Questions : To Whom it may Concern, With the new requirements for the NCT due, can you provide information on how the Decibel level of an exhaust is now measured? -Is it measured outside? - How far away from the car is the probe located? - at what RPM is the car taken to for the purposes of taking a measurement? - Is it a rolling test or a static test? Answers : · Distance from tail pipe to probe is 50cm at 45 degree angle · RPM is ¾ of max RPM to produce max output of motor · It is a static test (i.e. the vehicle is stationary) Should you require any further information please do not hesitate to contact me. Kind regards Cathy O'Brien Customer Service Dept. Quote Link to comment Share on other sites More sharing options...
