Turbo “flutter” is the reason blow-off valves and wastegates are installed on turbo setups. Blow-off valves divert high-charged compressed air that is traveling in the direction of intake manifold out (and not backwards into the cold side of the turbo) when you let off the throttle. Wastegate does essentially the same thing, but on the hot side of the turbo….but it does so by regulating hot side turbine speed.Really ? I've heard somewhere that flutters don't damage turbos. I guess its kinda like those things noobies like me dont know much about .
Appreciate the reply tho
That “soootoootoootoootooo” sound is high-charged compressed air trying to escape somewhere when the throttle is closed and the least point of resistance is backwards into your turbo (that is already spinning at god knows how many rpm’s in one direction). It’s the sound of your turbine trying to turn an opposite direction when it’s already doing x-amount of rpm’s in another directions.
