Re: Gonna be making a Billet Intake Manifold
Who did your simulation..I am a certified FEA simulation engineer...and they doesnt look correct. Also, in your simulation, one of the biggest things you need to be concerned about it getting the same amount of flow to each port.
Also, i build a manifold similar to your design several years back, except mine is welded instead of bolted to the top. Its tight, trust me lol. I can tell you i lost bottom end due to runner length, but gained top end.
Be mindful of size, cause the bigger your plenum, you will lose additional bottom end...
Just my 2 cents
