1. Stock MAF is 70mm (with ~58mm actual area), stock rubber boot is ~70mm inlet - 67mm outlet & PLEATED, stock TB is 60mm. Nothing optimized with that.
2. My idea is a large mouth filter (no restriction) to a 75mm bullet MAF (that exits at 70mm) to the stock rubber boot (MINUS the pleats - remember 70mm to 67mm taper!) & a 65mm optimized & polished TB.
The dual honed SVT upper intake opening is ~66mm for reference. That's a gradual taper from one end to the other. Inner wall "smoothness" very close and very sheer.
3. The stock MAF bar does disrupt laminar flow. It would cause eddies of turbulence on each side thus disrupting flow characteristics and velocity. BTW I specifically stated "Laminar flow disturbance" not the entire definition of laminar flow... Also if you wanted to get technical; this "supposed laminar flow" butts directly into where the intake manifold diverts. There goes your perfect flow right there.
(Why I said the venturi principle was more in effect when you take into account where the intake leads into)
