The difference is that compressor surge occurs while you're on the throttle and compressor blades in the turbo stalls. This causes loss of boost pressure, thus loss of horsepower, probably bad AFR. Over time, repeated compressor surges damages the bearings in the turbo and it goes kaputz.

What happens when a compressor surges?
Surging can cause the compressor to overheat to the point at which the maximum allowable temperature of the unit is exceeded. Also, surging can cause damage to the thrust bearing due to the rotor shifting back and forth from the active to the inactive side. This is defined as the surge cycle of the compressor.
Is compressor surge bad for your car?
Since the turbo is actually making significant boost, is at high RPM, and the pressure is fluctuating wildly because of the surge, these conditions do have the potential to cause greatly accelerated turbo bearing wear and/or damage to the compressor wheel.
Is turbo flutter bad?
If this is the noise that you associate as turbo flutter, then you're in luck. Blow off release isn't harmful to your engine or turbocharger in any way. This satisfying, turbocharger-specific noise should dispel any lingering doubts your friends had about what you have under your hood.
Why is my air compressor surging?
Surge occurs when there is no forward flow of gas through the compressor and a reversal of flow occurs. The gas that is being compressed gets pushed backward through the centrifugal compressor. When this surge (flow reversal) occurs, which can happen in milliseconds, the rotor is affected.
How do you detect a compressor surge?
Generally, the occurrence of surge is inferred from a rapid change in any measurement that is a direct function of compressor flow or head. As mentioned previously, compressor flow, discharge pressure, and inlet temperature are signals that can be used for surge detection.
Is compressor surge bad for the turbo?
The difference is that compressor surge occurs while you're on the throttle and compressor blades in the turbo stalls. This causes loss of boost pressure, thus loss of horsepower, probably bad AFR. Over time, repeated compressor surges damages the bearings in the turbo and it goes kaputz.
Why does my turbo flutter when I accelerate?
That fluttering noise is the sound of a turbo operating in compressor surge, as the compressor 'chops' through the air rather than pushing the air into the engine. ... To do this, it opens as quickly as it can when there is a rapid change in engine load from boost to vacuum — such as when a throttle plate closes.
Is no BOV bad?
Without a BOV, compressor surge can be a real problem on older, worn-out turbochargers — resulting in premature turbo failure.
Does a wastegate increase horsepower?
False! A wastegate is possibly the only component in your whole engine package that can be made smaller as you increase your boost/horsepower output – in certain circumstances. A wastegate drives exhaust gasses away from the turbocharger to regulate turbine speeds and boost pressure.
What is surging and choking in compressor?
Surge is a violent flow reversal that occurs when the process restricts the compressor flow below a certain minimum value. Choke occurs when the process does not create enough restriction to the compressor flow and the compressor operates at its maximum flow for a given performance level.
Does reciprocating compressor surge?
Surging is not witnessed in Reciprocating Compressors, as they are positive displacement Equipments where the pressure increased is by volume reduction, hence providing anti surge in reciprocating is not envisaged and not proper.
What is surge protection in compressor?
“Surge” phenomenon is common in Centrifugal compressors. ... To prevent the compressor from surges, a reversal of flow, process instability, and compressor damage, the compressor discharge flow is diverted to compressor suction via an anti-surge / recycle control valve.
