Engine Exhaust Flow Rate Calculation
The data shown in this section
Exhaust fow rate may be calculated using the ollowing ormula. Exhaust temperature and intake airfow rate must be determined to calculate the exhaust fow rate. Exhaust temperature and manuacturers maximum backpressure may be approximated using the chart below.
is a collection o inormation gathered by Donaldson rom various sources and should be used or estimating.

Exhaust Temp. (°F) + 460 540
Airfow x Intake = (CFM)
For exact inormation, consult your engine manuacturer.

Note: I you are spec’ing a dual mufer system divide engine’s exhaust fow (CFM) by two
Engine Airow Calculations CFM intake rate is available rom the engine manuacturer. I CFM specica tions are not available, use the volumetric eciency calculation. A simple calculation or cm is to multiple the horsepower o your engine by 2.5.

Engine volumetric eciency ratings are best obtained rom your engine manuacturer. Engines operating with electronic controls could have volumetric eciency ratings o more than 2.0. Airfow on these engines should be veried by the engine manuacturer.
