Well I tried the fixes suggested..air box...synthetic oil and the whine died down a little. I used the stick to the ear on the turbo method and did not hear any whining it sounds like it is coming from the belt. It does not start until it gets to temp. It goes away while accelerating comes back when coasting. The A/C is not working I think it has aleak could that be the issue??? By the way your PT is my PT's twin brother same color....
