Colector Prueba 3

What do you think?

after to many tests, got this..

Colector Prueba 7

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

Taper the back end to removr the turbulance and increase velosity. The long runners are going to shift your powerband down lower (which is probably where you want it in a 1.8t since vw motors all have longass strokes factory.)

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..

Colector Prueba final

I hope to get soon materials designet for welding everything.

I will post pics soon.

Thanks!

Walter, what flow modeling program are you using?

What format CAD drawing can it import?

Is it a free program?

Solidworks is awesome, but the Finite Element Analysis portion isn't especially good (meaning, not especially close to real life).

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:
