.... i found it interesting that the pressure gets gradually less in the inlets as you go from small end to large .


Me too, as if the taper was too great and putting excess pressure in the small end.

Also noteable, the first two (from inlet end) get the lowest pressure at their first edge, almost as if the shape of the trumpet at 90degree to the mass flow is acting classic Bernouili (ie, pressure drop over an effective aerofoil section).
That's why it would be interesting to know if it is simulated or real.


id imagine its off a simulation program i have a copy of rod .,its used by a lot of design houses , , it looks the same as that output .its usually very close to real world ,as long as the input data is accurate .

but in this case i think its a bit of a simplification ,its not including the back pulses from the seperate cylinders intereacting with each others flow , i think they are assuming the area precludes velocity pulse effect to a degree .

im tending more towards the toyota type of plenum nowadays ,especially if running propane in the inlet , as i have been doing on my latest engine .





this the plenums that kinda look like 4-1 tubular exhausts?
