So why did AR not take the Full Termi system and tune it as best they could with their RB or TB units then get some base line runs on the dyno to compare with the extensive time they spent fine tuning their own system?
Apples with Apples. Oh thats right that would not have helped with the sales or establishing a reputation for their new product.
I still have not received any communication from your lawyers Rich!
I think this shows the fully Termi tuned by rich with rapid bike:

Using the same model ad year bike on the same dyno can give different dyno readings, some will show higher HO and some lower, this is especially important when arguing about a 10 hp difference.
Please check out the following information at
Factory Pro: Producers of the EC997 Low Inertia Eddy Current Dynamometer Series and Quality MC performance products a link was already posted here previously:
Factory Pro has confidentially refused to exaggerate measured and corrected horsepower figures to sell more dynos.
Since Factory Pro hasn't rescaled horsepower for the last 20 year and our software reads the same files the same from the very first EC997 dyne system.
Some Dynamometer companies add to measured rear wheel power readings a factor that is based on ESTIMATED rear wheel power losses (under what power conditions? 125cc? 1200cc? under coasting conditions? with a 3.00x17 bias ply tire? a 190x17 radial tire? New heavy radial tire vs. worn old, light, stock bias ply tire? Who knows?)
In short, there is NO meaningful "average" tire to get a correct rear tire power transmission loss measurement for all bikes - so obviously, unless they actually measure the power lost in the rear tire, under driven load conditions, NO dyno company should BE ADDING incorrect power figures into the measured power. It's simply wrong.
The fact that they add varying amounts of power to the actual, "true" amount of power delivered and measured to the surface of the drive roller creates a situation that makes it an onerous task to compare power figures from different brands of dynamometer systems.
On simple inertial dynamometers, some (most, actually, all that I know of in the MC market) companies use an average for the inertial mass value of the engine, transmission, rear wheel, sprocket and chain on every bike - as if a YZ125 has the same rear wheel or internal rotating mass as a 1340cc Harley Davidson. Needless to say, if the software thinks that the YZ125 had a HD rear wheel on it, it would look like the 125 makes more HP at the rear wheel than it does at the crankshaft. It's simply wrong.
And - that's why you hear of 125cc Karts that make 43 hp at the rear wheels!!!!!
It's expensive to measure frictional losses in the engine and drivetrain, requiring the dyno to be able to drive the vehicle with engine off. Add the cost of a 50+hp electric motor, controlled power supply, etc. It's just not likely that $20,000 dyno will be equipped with that equipment.
It is also common for dynamometer companies to add to the power readings by adding transmission and primary gear/chain losses back into the measured power readings. Some companies make a concerted effort try to measure frictional losses and, optionally, add the power to the measured readings. Other companies - some that would surprise you - say that it's not important and give a blanket, single factor for frictional losses in every engine. That includes some $25,000-$35,000 dynes.
Some simply say that there is a meaningful "average" for every motorcycle,(2 stroke, 4 stroke, 1 cylinder/1 transmission, 4 cylinder/1 transmission) and apply it to every bike and that it is not a significant difference.
Blanket estimates of "average" losses and corrections are, quite simply, incorrect. At the upper levels of the industry, (we are talking about $150,000 - $500,000 AC or DC 4 quadrant dynamometers) it is not tolerated - shouldn't be - and needn't be.
There is a dyno company that actually has different versions of software that displays their own identical data files as different amounts of power depending on whether you use the DOS version or the Windows version of their software!!
