The proprietor, Julian Edgar is a fan of the Dwyer Magnehelic Differential Pressure Gauge and shows how to use it to size vents, ducts and airboxes, and intake and exhaust runners. Why you need a bellmouth in your plenum. :thumbup:
There's a lot there (768 articles) but a lot of it is on suspension, electronics, etc. For your purposes maybe AutoSpeed - Building an Ultra Light-Weight Car, Part 2

I have a lot of experience with Magnehelic gauges... they're on every single air handling unit at work to measure filter differential pressure. I can pick a couple of them up from eBay.
I especially like their "Building Ultra Light-Weight Tubular Frame Vehicles", "Working With Tubular Frames" and "Making Parts Lighter" series:
