1) I do not know everything, especially when it comes to unsteady flow dynamics.
2) I have done a lot of research on intake design over the last 13 years in my free time, but I am still nowhere near an authority/expert on the subject. It is just one that fascinates me and I may have an unhealthy level of interest in it.
3) I DO know that even when playing with advanced maths and analysis, that there are still 9302934021 things that aren't being accounted for, or cannot be predicted. If you have done well, and get lucky, you may find yourself in the ballpark of where you need to be. Real world testing, when possible, trumps mathematical analysis all day everyday and 3.14 times on Sunday
4) Even when testing a manifold design on a flow bench, there are still at least 2814731 things that aren't being accounted for, or cannot be tested.
5) The only 100% accurate testing and analysis is performed with a manifold installed on a car with proper measurement equipment (dyno, etc)
6) The time, cost, and knowledge involved in thoroughly developing the ideal intake manifold is unrealistic for anything short of an F1 team, and even then, they have to draw the line somewhere.
7) Assumptions must be made. Whether they are good or not, you must make assumptions. If and when the end product doesnt work as intended, you must re-visit your assumptions and make adjustments.
Now that is through, this thread is for us to exchange thoughts and theories about taming the crab under the hood.
Question
B C
A few of us here are interested in designing an intake manifold for an M20, and a few have already started working on them.
SOME DISCLAIMERS
UNLESS YOU ARE A NERD, THIS WILL BE AN IMMENSELY BORING THREAD FOR YOU.

Dear Earl, 2 nights ago I had a dream that I swapped a rebuilt M42 into my car (with my current turbo and such). It sucked. true story. sincerely, Snapple

The inside will be ported and smoothed out, but just showing how nice it is before that. This is just the start of shaping the plenum. Just trying to get some excitement for me to finish lol

I will avoid doing elaborate maths if at all possible, for the sake of my time, and your sanity, but if you would like to punch out some elaborate maths, please feel free to do so. This is from an
