Using A Dyno For The First Time

A dynamometer is a useful tool when trying to improve the performance of your machine. However, when you are using a dynamometer, it is easy to make mistakes that will cause the reading to be off. Making certain corrections to your engine will ensure that you will get a much more accurate reading. 

Determine Whether To Purchase One

When using a dyno, it is important to determine whether you should purchase one or find a shop that has one and take your engine there. Shops that can test a dyno are very common and it is likely unnecessary to purchase a dyno that you will not use frequently.

Choose The Right Type

Make sure that you are using the right type of dyno. An engine dyno is designed for when the engine needs to be removed from the car to be tested. The chassis dyno, on the other hand, is designed for when the engine can be left in the car when testing it. Since the chassis is much easier to use and less expensive, it has become a much more common option.

Know What You Want To Test

Before you begin using the dyno, make sure that you know exactly what you would like to test. Do you want to test the exhaust, emissions, throttle body, fuel injection, or valve timing. When you know what you are looking for, you will be much more able to identify problem areas. 

Make Sure The Temperature Is Right

The drivetrain must be at the operating temperature. If it is at less than the operating temperature, the lubricants will be thicker, which leads to a reduced power output. You will need to measure the oil temperature using an infrared thermometer and point it at the oil reservoir. If the oil temperature is not at least at 180 degrees Fahrenheit, you will not get a consistent result. 

If your engine is overheating, this can also lead to an inaccurate reading. The last test might show less horsepower than what it should. This is an indication that your engine has overheated and will need to cool down. 

Check Pressure

When you have low pressure tires, this can lead to an inaccurate reading. For example, a low pressure rear tire can lead to excessive friction and heat, which can reduce the power of the engine. If the tire might be the problem, fill or replace the tire before performing the test to make sure that you get an accurate reading.

If you prefer, have professionals, such as Power Test Inc., do it for you.
