Blackbird Transforms to 935 K3 Phase 1
#72
Phase two, in efforts to replicate the factory look of the very early turbo race cars (baby turbo 2.1 and 935-001) I did my intercooler plenum externally as I saw on the factory early cars. Not only is this my first time doing fiberglass work but at the same time the inside of the box is perfectly smooth for non-turbulant airflow etc.
The IC core has AWESOME flow through, but even so at 200+ mph the volume of air will be large that is moving through the compartment. So with the angled sides this is to discourage air stall or hot pockets of air as in box corners after studying some airlow diagrams, that is where the air would go in lieu of being pushed through the IC.
Ducting is 5" hose from the side intakes (top of each quarter panel)

Also just for reference each lower intake in the rear quarter panels goes to an oil cooler (as well as the center air dam in the front end) so all intakes and NACA ducts are functional.
