4.1. General requirements
There are many possible facility requirements and room layouts for a
chassis dynamometer. Testing needs vary from basic power runs to
extensive R&D to mileage accumulation, with power levels ranging
anywhere from 50 to 1000+ HP. It is not possible to recommend a generic
design which will fit every customer’s needs and budget. These
instructions merely attempt to point out the issues you need to be
aware of when designing and building your facility. There are four
general categories of such issues:
1. room issues
2. safety / environmental issues
3. technical issues
4. convenience issues
In all cases, you should consult with your architect, contractor, me-
chanical and electrical engineers, and with city planning and regional
building offices. Your SuperFlow Sales Associate or Customer Service
representative will be happy to assist you with general design advice;
however, they cannot reasonably be expected to provide detailed
engineering services for each facility.
4.2. Room
4.2.1. Room size
The dynamometer room should be at least 12’ (3.6 m) wide, 26’ (8 m)
long, and 8 to10’ (3 m) high. The larger the room, the more expensive
the construction, and the more difficult it is to achieve significant
ventilation air speeds. A larger room will however have greater thermal
mass and is easier to maintain at a constant temperature.
Your room should be large enough to comfortably accommodate your
vehicles and accomplish your tests, but not much larger.
You will need to determine if you prefer a pit-mounted or a surface-
mounted dynamometer, and evaluate the resulting lift and platform
requirements, or the pit size. SuperFlow has typical pit drawings
available. They are included at the end of this section. For surface-
mounted dynamometers, a platform kit is also available.
The AutoDyn design is essentially uni-directional , although opposite
rotation is possible without negative consequences. The position of the
dynamometer in the room depends on the requirement to test either rear-
wheel drive (RWD) or front-wheel drive (FWD) vehicles. If both RWD
and FWD vehicles will commonly be tested, the room should be longer
to accommodate both, while maintaining the same direction of rotation
on the dynamometer. If your room size and dynamometer positioning
requires turning the vehicle around for testing either RWD or FWD,
