What sort of power level and speed do you need to determine data?

There is a cheap and allegedly reliable one available for a PC.

As noted above, check out www.globalspec.com.

You will need to state Shaft O.D., Maximum torque

(or maximum power at a specific RPM), RPM range, any

transient conditions and any torsional resonances.

If the ambient temperature of the test is important,

be sure to state.

There are also numerous torque measurement methods.

Be sure you investigate which is best for your application.

The Rototest Dynamometer

Rototest's dynamometers have, over nearly two decades, repeatedly pushed the boundaries of what to expect from chassis dynamometers. The cutting edge dynamometer concept includes direct-coupled, hub-mounted dynamometers and a groundbreaking measuring system that brings the measurement accuracy to an unequalled level. The Rototest dynamometer has over the years helped auto manufacturers, research organisations, OEMs, tier-one suppliers, race teams, performance specialists and numerous others - to increase the quality of their products, make their cars win more races and to perform at a higher level.

Jamar Hydraulic Hand Dynamometer MODEL 5030J1 The classic JAMAR Hydraulic Hand Dynamometer has been the standard in grip force measurement for over 30 years. The tradition continues with enhanced accuracy and reliability due to significantly improved, virtually leak-proof hydraulics. Accurate and precise stainless steel gauge is protected by an exclusive shock-resistant rubber protective cap. Wrist strap prevents accidental damage. High quality, die-cast aluminum five-position handle easily adjusts to fit virtually any hand. Measures force from 0-200 lbs. Includes instructions and norms in an attractive carrying and storage case. Full two-year warranty. Price $239.00

Check out GlobalSpec, JesterTerrestrial. This link will allow you to search for a dynamometer by product specification. If a list of suppliers is what you're after, GlobalSpec also has a list you can use.

I have done this caveman style before.

Put the engine/motor on a hinged plate.

Put a bar on the plate that aims at the shaft CL

Put a loadcell or a 1" hydraulic cyl with a gauge

Write down the first gauge reading then put 100lbs at 10' on the bar. Then read the gauge this will be 1000 ft lbs. Subtract the first gauge reading from the last and divide it by 1000 to give the gauge increments of 1 ft lb. Measure the torque and rpm your done. In the case I did we ran the engine at several rpm to establish a base line for the engines external power use the hooked up a drive shaft to a gear head and did it again and them hooked up the gearhead to an axial flow pump (with a venturi meter) sans water and did the data again. All of this the isolate the power used. At last we ran the efficiency tests for the pump. With this test we new the power requirement of each component and the actual power requirement of the pump alone.

Oh yeah, I almost forgot we put a 5 gallon bucket on a scale to measure fuel usage. The 5 gallon bucket became the fuel tank and fuel was added to it to keep the scale in a bracketed accuracy range.

I said all of this to point out that a test that is incomplete is not a test at all.

I'll go reeeaalll slooooww so it's easy to understand:

1.turn on your computer

2.access the internet

3.in the space on your home page labeled "Search the Web" enter the word dynamometer.

4.read results

Where do all these underachievers come from that haven't the slightest idea of what a search function or engine is nor how to use one?

I'm amazed that they are able to even post their elementary inquiries on CR4 !

Then considering it was posted by "JesterTerrestrial" he is making an attempt at "Winding us up."

His name tells all. I'm surprised he didn't post anonymously.

In the future I will simply ignore such.
