    You have to insulate the area around the turbo. I think they used to sell a custom fit graphite, fiberglass blanket that would go over the turbo but not sure it they still sell them. Check Summit Racing.

     WRONG FORUM. This is the Cars & Transportation Maintenance & Repairs forum. For HVAC air blowers you should find a different website than Yahoo. Try the manufacturer's website.
