direction of air flow on IC??
Found an 88TC IC that I want to mount on the "project" sand rail with an 83 TC engine. The IC has different sized openings. Which way does it go on, with the larger opening towards the turbo or the larger opening towards the throttle body? One person said the larger opening is from the turbo and the smaller is towards the throttle body, is that correct? Something to do with velocity???

The smaller opening goes to the turbo, the larger to the TB
