more advanced fabricators might use this info

once you get into fabricating engine components youll rapidly find your skill with a welder and a milling machine are almost mandatory skills.
obviously port work on a aftermarket intake might be far less risky but at some point youll eventually want to use a custom designed intake manifold.
yet youll soon find that most aftermarket intakes are designed more with ease of casting and low cost rather than maximum performance as prime requirements, in their design.
but the fact is that youll need to understand what your doing and why your doing it, its not like you can randomly select runner lengths and cross sectional areas or plenum volumes randomly and expect to get better results that the factory intake designs or the better aftermarket designs put together by engineers with at least some basic understanding of flow , velocity, restriction, and intake runner charge inertia, keeping fuel in suspension and how exhaust pulses and reversion interact..
yet that does in no way indicate that you can,t significantly improve the flow rates and increase the efficiency on your engine if your careful at observation and understand what your looking at.
