Most pulley or belt noises wont go away with rpm increase. Some will be louder while others might make a different pitch. Im not sure what kind of high pressure would encounter. Might be a vacuum leak.
hmm ima have to take a closer looks see if any vacuum lines are loose only reason i dont think its a belt or pulley is because it keeps going after the engine is cut-off. thats why pressure release sounds more like it..
