The difference between the SC and Carrera het exchangers inso far as the heat is concerned in the angle and position of the heat inlets
SC heat inlets are in the same position and angled as in the SSI shown here at points A,
ie angled outboard
Carrera heat inlets are similar to the 964 s shown here, angled more to the back, the CArrera inlets are rounder than the ovalized 964 inlets.
