Eisenmann E82 1M exhaust testing.
As Eisenmann GmbH approaches the end of the research and development stage of any exhaust system, final tests are conducted to ensure perfect fitment and function of the new design.
Eisenmann technicians dyno test the prototype exhaust system to ensure that the flow improvement predicted in their CAD modeling shows itself in the real world, and use acoustic testing and waveform analysis to check the sound output of the exhaust system. Eisenmann’s testing and development equipment allows the engineers to simulate exhaust pulses through test mufflers before a real car is ever run on their dyno, but nothing is as accurate as real world testing. For this, Eisenmann’s microphones allow them to do acoustic sampling and advanced wave form analysis to not only detect but also tune out unwanted sound frequencies. Finally, Eisenmann uses a Zeiss FaroArm to rescan the finished exhaust system, in order to verify that the production system is millimeter to millimeter the same size as the exhaust system originally designed by Eisenmann’s engineering team. This allows Eisenmann to verify their fabrication jigs and create an exhaust that is a perfect fit, every time. Please follow the below links for tours of Eisenmann’s manufacturing facilities and more information on Eisenmann’s development process, and enjoy the photos! http://eisenmannblog.com/2011/04/08/ind-eisenmann-tour/ http://eisenmannblog.com/2011/04/08/...outsourceable/       + 10 BHP; +10 N
