The tests Flowmaster mufflers go through
It is known that Flowmaster mufflers are one of the best there is today, but how do these exhaust parts become like these? Numerous tests and research had to be done to ensure each part’s efficiency. Flowmaster said that real-time track and highway testing are done, but aside from that its own SuperFlow dynamometer perfects each muffler and exhaust part for the optimum performance.
Flowmaster also uses Bruel & Kjaer real-time spectrum analyzer that takes care of the muffler and exhaust system research and development. According to Flowmaster, “not only can the analyzer be used to measure sound levels, it can also be used to fine-tune exhaust tone and locate unwanted vehicle interior resonance sources.”
Flowmaster also has a SuperFlow SF-7100 Engine test system which is a water brake engine dynamometer capable of determining endurance and performance. According to Flowmaster, “the brake will absorb up to 2000 lb-ft of torque and the computer-controlled system will record up to 50 separate channels of data each dyno pull.”
Along with this facility, Flowmaster is also equipped with a SuperFlow SF-840 chassis dyno. It is a Inertial type chassis dyno that is controlled by Eddy Current electric brakes through a dual computer. The dyno can keep the vehicle steady and can power up to “1000 hp at the rear wheels, and a 200 mph top speed.”
From these technologically advanced procedures come high quality mufflers that can increase horsepower, torque and fuel economy while minimizing exterior sound levels and reducing interior resonance of the vehicle. One of these is the Delta Force race mufflers. Backed by the Delta Flow technology, this muffler “provides superior scavenging of exhaust gases.” It achieves this by using multiple deflectors, which has an advantage over a single deflector because the multiple deflectors reduce the chance of turbulence.
Performance can be heard and that is what Flowmaster does best.
