That noise is from the slow blower speed due to the large pulley and low idle rpm. A 3.5+ pulley with a 550-600rpm engines idle speed causes the gear case to make that noise. When you pulley down and/or raise idle rpm it quiets down.

Thanks, yes Im aware of that being a common issue. Mind you mine still has some rattle above idle and seems to have gotten louder not quieter over time. I actually wonder if its the coupler/front bearing (assuming there is one?) rather than the screws. Despite that, its an annoying sound for an otherwise great sounding car.
