Sound dogs is a good first stop, but let's clarify. The ones you wrote are cartoon sound effects... not exactly comprehensive.
Do you need the sound of a blender -- start, run and stop?
The bridge of an American Los Angeles-class fast-attack submarine as it dives?
The sound of a BMW touring motorcycle driving by at 35mph... not Harley Davidson and not Honda?
3 minutes of ambience from the food court of the Mall of America?
They really do get that specific.
