I got a D15B in my CRX, with ITB and airbox coming. I just want to see how people have their hood ducts/scoops setup. My plan is to have air rammed into a modified motorcycle airbox. Anyone got pics or ideas? I prefer a NACA duct to keep the lines clean; should I go for one large duct or two small ones? How big?

Also, anyone that's an expert on fluid dynamics/aerodynamics, got any templates or formulas for NACA ducts?

thanks
