Title: making intake manifold
Post by: walter on May 14, 2013, 11:27:00 AM: Hi guys, im designing an intake manifold i have to fab for a VW 20Vt big port, i will keep stock runners but i will make a new plenum, ok, problem im having is 4Cyl isnt getting enought flow than the other cylinders..im trying to get the best design for to get it , trying and dont get it..gave some degrees to throttle body, wrong, change sizes of plenung..not luck..not sure if anyone can give me some tips...

here is some vids..

first test - flow simulation (http://www.youtube.com/watch?v=jEUmOcKUiQ0#)

Prueba 2 (http://www.youtube.com/watch?v=CngSiZPZeJs#)

Colector Prueba 3 (http://www.youtube.com/watch?v=jS7-Gx3nW60#)

What do you think?

Here is some link that maybe helpful:

Colector Prueba 7 (http://www.youtube.com/watch?v=8woPynMkjpQ#)

i'd like to learn more about this, measure each port and so but this will give me a good advice so far.

Post by: walter on May 16, 2013, 08:51:47 AM: these runners are only for to see what flow/density is get , distance is similar to the stock runners i will keep.

This s the final test..

I hope to get soon materials designet for welding everything.

I will post pics soon.

Thanks!

What format CAD drawing can it import?

Is it a free program?

Kool, I did not know Solidworks has a flow simulation. :noel:

Post by: FreshDA9 on December 04, 2013, 02:55:44 AM: Can that simulation also be done in Autocad/Autodesk? im actually taking a drafting class next semester and wanted to see some flow simulation on an intake manifold idea i wanna try on my car. If its only a Solidworks thing ima have to grab a torrent and try it out. :noel:
