Here are some Frequently Asked Questions regarding our
Dyno services:
- 1. What is a chassis dynamometer?
- A chassis dynamometer is a treadmill for
cars. When your car, truck, bike, etc., is driven
on the dynamometer rollers. Road, track,
off-road, etc., conditions can be simulated:
• Low speed,
high speed
• Normal
level road
• Up hill,
down hill
• Trailer
loads
- 2. Why is dyno tuning better than
“ordinary” tuning?
- You drive your car in gear and under load.
You should get it tuned in gear and under load.
This can only be done on a dynamometer.
- 3. Why is your Dyno Dynamics
dynamometer better than other dynamometers?
- Dyno Dynamics dynos enable us to accurately
diagnose a host of problems. With it, we can
safely operate a vehicle under any load under the
control of the dyno. No other dyno offers the
accuracy, sensitivity, and vehicle safety of a Dyno
Dynamics dynamometer.
- 4. Can you tune fuel mileage on the
dyno?
- Yes, we can lean out the part throttle and cruise
areas to net better milage and actually save you
money.
- 5. Why is road load testing better
testing at rest?
- A vehicle in "neutral gear" at rest on the workshop
floor does not behave as it would "under load" on road.
It’s quite possible for instance, for and engine to run
rich at idle and just above idle, but be dangerously
lean when cruising along the road. Spark plugs,
injectors, fuel pressure, carbs, fuel pumps, electronic
sensors, may be fine at idle or "free revving", but
perform poorly under load. So, these components can
never be checked properly inside a workshop without a
dynamometer. To road test a vehicle for a slipping
clutch, a misfire, a flat-spot, or vibrating
tail-shaft, takes time. A road test also introduces the
prospect of an accident with your car. Our Dyno
Dynamics dynamometer saves an enormous amount of
valuable time, and complete isolation from traffic.
This totally eliminates accident damage to your car.
Because a technician can produce "hills", "level road",
etc. at the flick of their fingers, much time is saved.
Our Dyno Dynamics dynamometer saves you time and
money.
- 6. Can my car be damaged on a
dynamometer by putting on too much load?
- No. Assume a car is being driven on a level road at
say 55 MPH in fourth gear. The car comes to a hill
(more load), the driver does not move the accelerator.
What happens? The car simply slows down. If the hill
becomes steeper (even more load) and accelerator
remains constant, the car slows down more. The
situation on the dynamometer is the same. If your car
is driving on a Dyno Dynamics dynamometer and load is
increased, the car will simply slow down. Apply more
load, and it will slow down more.
The load the Dynamometer applies cannot stress the
engine any more, (or any less) than a hill.
- 7. Does running my vehicle on a
Dynamometer wear out my tires?
- No. Tires wear out when ever they are being driven
on the road or on a dynamometer. Our Dyno Dynamics
dynamometer has advanced design. In particular the
roller surface is knurled with a square cut knurl. This
knurl combined with specially designed Dyno Dynamics
Traction Control System provides excellent grip and no
excessive tire wear common on other dynamometers.
- 8. Can the dyno check my
speedometer?
- Yes. Our Dyno Dynamics dynamometer can check
speedometers. We can also check your odometer accuracy
as well if you like.
- 9. Can I test to see if my new high
performance part actually made more power?
- Yes, absolutely you can make a baseline pull in the
stock configuration and then return at a later time
with you new part installed and see what kind of gain
you actually made.
- 10. My car already runs very good,
why would I want to have you dyno tune my car?
- There is a lot of power in small things like timing
and spark. Sometimes small things like timing can net
30 horsepower.
