Dyno Center

INTRODUCTION

Stendec offer an absolute guarantee of repeatable performance and are able to offer the latest services and tuning equipment to further enhance the latest technology courtesy of our very own Roehrig Dyno shock-testing bench, hooked up to the latest computer software.

Stendec are the only company in the UK to offer this advanced type of tuning.

Launched as the Footprint Dyno Centre, this technology (normally only found within motor sport teams at the cutting edge) is the only way of accurately tuning suspension to insure a wide range of adjustment and reliability.

Stendec’s Footprint Dyno Test will take your fork or shock through a fully dynamic test (CVP) consisting of up to 1600 cycles per minute, at various stokes from 1 to 3 inches and at different speed intervals. It measures heat build up as the test progresses plus seal drag on compression and rebound stroke, tests all moving parts of the unit, gas pressure, the behaviour of valve shims and fluid and the effects of cavitation.

After the initial diagnosis we can give you a number of options of how to increase the performance of your shock or fork. This then becomes the ‘footprint’ for your shock and will always be the starting point from which to work from. Every time your fork or shock comes in for a service we can recreate that exact performance. If you want some thing different like slightly less/more compression or rebound or progression settings we can give it to you and show it on the shocks own performance graph.

We are taking the question marks away. Period.

WHAT IS A SHOCK DYNO:

A shock dyno tests the ability of your shock to absorb compression and rebound forces at varying levels relative to its internal set-up. This computer-controlled machine actuates the damper at a number of known speeds and measures the force generated, it produces a graph plotting the ongoing test as the shocks temperature rises. As you observe the progress of the test the graph can reveal many stages that the shock goes through when used in a competition environment many tuning issues can be resolved using this state of the art equipment which normally would go undetected.

The Footprint Dyno displays all the above information on an easy to read graph of two types. Supplied to you on paper or CD. You can also request DVD of your shock being Dyno run.

Continuous Velocity Plot (CVP) and Peak Velocity Plot (PVP).

Continuous Velocity Plots collect data over a complete cycle.

Peak Velocity Plot runs a damper at several peak speeds and only collects data from the maximum force at each speed.

PVP tests are mainly used for mass production units where general information is enough. CVP tests are for true performance, giving critical information where specific set up is all-important, this is the only way to get the maximum potential for the intended use. A dyno run suspension is your proof of performance! Actuating the shock by hand or hand dyno-ing as some call it falls short of any guarantee of workmanship.

In short, if its not dyno tested then you don’t really know.

Constant cycle dyno:
This test actuates a shock or fork at up to 1600 cycles per minute. This gives a performance graph over a range of increasing heat build up which is experienced by the unit in a competition environment. The footprint dyno tests for:

1. Compression performance

2. Rebound performance

3. Shaft velocity at 5 strokes/sec; 10 strokes/sec; 15 strokes/sec

4. Three different stroke cycle lengths

5. Pressure balancing

6. Seal drag

7. Cavitition

DYNO FACTS

Some people use Data acquisition equipment to gain information from whilst riding a particular course. Though useful to a degree, this type of data collection only tells a small portion of the information required when resolving tuning issues.

Roehrig’s CVP dyno bench has been developed to test a damper unit in every way possible, it is most useful when testing for minute problems incurred by heat build up, the cause of hysteresis, gas pressure fluctuations and shim stack inconsistencies.Using the dyno bench enables the tuner to set the damper to have a much larger degree of damping control.

TESTING ADJUSTMENT SWEEP

This test is invaluable when trying to detect the effects of compression and rebound and what happens to one when the other is adjusted.

In a perfectly balanced tuned damper the adjustment (for example) of say the compression should not have any effect on rebound and vise verse. It is vital that there is minimum disturbance to each parameter when adjusting for a particular course.

Again without the Roehrig Dyno bench this can be easily over looked.

From a detailed fact sheet filled in by you, we can interpret how you want the shock to perform for your particular usage.
