    Do you mean to roll them from flat tube? This was the best design I could come up with for the application, cost didn't come into it all that much, its nice to make things cheaper, but the customer will pay all the costs, and would rather not skimp on £40-50 here and there if it will make even a slight difference to performance :)

    Oh right, never done much with solid works, im an autocad man myself, my brother works with solidworks tho so might have to enlist his help, is it just a case of getting equal flow to each inlet?

    36id seems about right for what i need, my ports have a 35mm id circumfrance so should be ok.

    how much roughly are they? pm me if you wish.

    hey rick have you thought about using cfd (Computational fluid dynamics)
    much better than solid works mate
    pm me if you want it buddy :)

    ps at what flow rate or pressure did you do that last low at?

    The last was at a pressure of 2 bar to 20 in mercury.

    Heres a few pictures (remember my camera is broke) of the inlet manifold half welded up.

    Excuse the dirt etc its been sat in the garage gathering dust, needs polishing and finishing. I do so much stainless i forget how to do ally!

    that inlet looks very nice...

    it reminds me of the DP item made for the 16v 106 engine...

    Similar to some of the inlets we've been making.

    Done a few different designs now but always forget to take pictures.

    Heres a few pics to brighten up the thread again.

    to fill the work piece with the gas being used to expel the air so it will weld correctly on both sides of the joint

    Can you use any gas? ie tig with argon and fill the tube with cheaper co2?

    I love looking at those manifolds :D I hope I can one day do something like that. Just need to take my TIG out the box and learn

    Would be interested to see the jigs you build for these, I'm building an exhaust system for my bike and there may be scope to build more for people. So may help to build a jig, but not sure the best way to do it.

    Cheers

    Thanks Vernon, your projects are awesome so can appreciate how long things take.

    An engine torque mount, this saved 1.2kg over the cast item.
