WebOnce your compression test is complete, your results should consist of six numbers (one per rotor face) plus a cranking speed. Most specialists will provide you with the six results already normalised to 250 RPM. This is important because the cranking speed has a direct impact on compression test results and any changes to the standard RPM rate ...
