Ed Pink Racing Engines Dyno Test With An Extreme Muffler
Ed Pink Racing Engines (EPRE) is one of America’s premier auto racing engine building, rebuilding, testing, design and development facilities.
Below is a dyno test that Ed Pink Racing Engines did on one of their 4 cylinder Toyota USAC Midget engines with and without a muffler.
Muffler used is part number 3525-3030-8
Notice how actually running with the muffler did not effect the horsepower or torque curve. If any thing it improved it a small amount.
