Started with a yellow spring inside and had no "whoosh" noise. Then I tried a white spring with the same result. I lubed up the piston ring and I can see when I start the car the piston is closed. When I rev a bit, it opens but no noise at all. What am I doing wrong?

Are you building boost? It's not really going to make noise if there isn't any pressurized air to vent.

Have you driven the car in boost instead of free revving it in neutral?
