Vibration, as a result of unbalanced turbochargers, is the main issue when dealing with unbalanced turbochargers. It absorbs a great portion of the energy produced by the turbo, which is wasted because it does not contribute to the engine’s overall performance. Instead, vibration becomes the main source of premature failure in an engine and mechanical parts, such as bearings, bolts, and belt may be destroyed – in worst cases the turbo will make unacceptable noise during operation and fail within days.
Using parts which are not precisely manufactured to the specified flatness, tolerances or dimensions, can lead to an accumulation of component imbalance issues, again causing premature failure of the turbo.
