The DYNOMET portable road dyno
is a device mounted on a vehicle's wheel which
measures the vehicle's power by accelerating it in one
gear on a stretch of straight road. It can be used on
many types of vehicles regardless of the power they
generate and what type of drive they have.
The DYNOMET portable
road dyno can measure the power of
passenger cars, sports cars, 4x4s, SUVs, vans, light
trucks and heavy trucks! If you can attach the sensor to the wheel and
accelerate the vehicle on a stretch of road,
the DYNOMET will measure its power.
The DYNOMET portable road
dyno differs from typical roller dynos in that the sensor usually located on the rollers
measuring their rotations is attached to the vehicle's
wheel measuring its rotations. The typical roller dyno's software knows the roller weight and
circumference thereby allowing it to measure power. The DYNOMET
portable road dyno's software simply uses the weight of
the vehicle and the wheel's circumference. That's it -
that is the only difference and the principle is the
same - a certain mass is accelerated to a certain speed. The rest
of the test looks exactly the same. On the roller type
dyno the car is accelerated in selected gear and the
rollers simulate the road; when using the DYNOMET, it is
accelerated on the road.
The DYNOMET portable dyno can measure:
- power and torque,
- any acceleration (0-100 km/h,
0-160 km/h, 80-120 km/h itd.),
- 1/4 mile time and speed,
- braking distance.
The sensor has a resolution of 60 impulses per one
revolution allowing for precise measurements.
The DYNOMET portable dyno
has many advantages:
- precision: if the weight and wheel circumference are
correct, the margin of error is less than 1%
- the vehicle is tested in its natural environment, with
perfect cooling of all crucial components, which can be
a problem while testing in a workshop,
- the software was developed with road tests in mind - to
perform a standard power test usually around 800 meters
of relatively straight road is required.
The DYNOMET software allows comparison of up to 4 graphs and has
in-built DIN70020 temperature and air pressure compensation.
Advantages over a standard roller set dyno:
- no maximum power limit; the DYNOMET portable road dyno
will measure any power as long as an adequate stretch of
road is available,
- ability to test vehicle's acceleration,
- tests cars in their natural environment,
- does not take up valuable workshop space,

Price: 2190 Eur
(this is the net price exclusive of VAT for companies
with EU VAT number; prices for companies outside
of EU are +23%)
A laptop is needed
to operate the DYNOMET dyno and it is not
included in the package.
portable dyno is upgradable to a roller type
dyno since the controller and software is
the same throughout the entire dyno range.
