Torque = angular acceleration x inertia.
From the torque� it is easy to� calculate horsepower, and this is presented in graphical form.
Rates : $50 for first hour, after that, negotiable....

| The most accurate way to test your gokart engine is to use a dynamometer.� I have an inertia dyno capable of testing kart engines up to 50 hp. At present the dyno uses the standard kart engine mounting system. I hope soon to have a chassis option available.� A test run takes no more than 20 seconds, and you will receive a graph of hp and torque: | ||||||||||||||||||||||||

| This graph shows some of the improvements I made on my Suzuki RGV 150 kart motor. The black line is the stock motor, the blue line is the new expansion chamber we designed using MOTA ( two stroke simulation). | ||||||||||||||||||||||||
| �The red line is the step up from standard to carbon fibre reeds. | ||||||||||||||||||||||||
| ���� | ||||||||||||||||||||||||
| �The dotted lines show the torque produced on each run. | ||||||||||||||||||||||||
| The power is measured at the wheels after all the gearbox losses. | ||||||||||||||||||||||||
| �� The inertia dyno works by measuring� the� acceleration of a known mass� ( a 100kg disc) and� Torque = angular acceleration x inertia. From the torque� it is easy to� calculate horsepower, and this is presented in graphical form. |

| � Is the dyno accurate? A common question. In reality, I don't believe there are 2 dynos in the world that will give the same readings on the same motor. It is much more important that the dyno be repeatable, that is, if you change nothing on the motor, will the two runs give the same results. My dyno is corrected for temperature, pressure and humidity, so runs done on different days will be corrected to a standard day and can then be directly compared. | ||||||||||||||||||||||||
| �� The dyno is best suited to exhaust, ignition and carburetion changes. I can quickly show you whether that $450 pipe you bought actually works. I can also check the accuracy of your tacho.... Rates : $50 for first hour, after that, negotiable.... |
