Thats a term for a poor tune on a roots blown engine.
It can't idle smoothly and surges. Goes from 500 to 2500 rpm and back repeatedly.
Makes it extremely hard to get staged in the lights and just sounds like crap.

Most people thing it's cool

Blower surge is when an engine idles high for a second and then drops in rpm a lot and because the supercharger is not spinning the engine gets a lot of fuel and idles higher because of that the supercharger add or air and evens out the mixture because of that the engine idle lower and then the cycle repeats

O K. I've heard supercharged cars idling eradicley like that before. Never heard it being described as a good thing.
