Manifold i've just made

[Rick]

hi, nice work with the manifolds, what basis did you design your inlet from, how did you know how much volume and how much to taper it off etc? how much would it cost for you to part with some of them stacks? to save me having to mess around and turn some?

what id are the stacks?

Have you thought of making a flare, to form the bellmouth from tube

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

Its designed on solidworks. We cover all aspects of tuning, so I had a good idea of what works and what doesn't. Started with this then did various flow simulations. Baised on different power levels etc worked out the airflow in CFM and entered that into the software. It then gives you speed data for each port and each part of the inlet.

The velocity stacks for these inlets are small. 36mm ID 44mm OD. What car are they for? I'm having some bigger 1's machined in a couple of weeks, depends on your power and the size of the stock head at the moment.

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.

Yhpm.

Some early flow testing of the manifold on solidworks.

wow you are an awesome welder, top work. pm sent rick

Thanks,

Replied.

Heres the final flow test of the inlet manifold above.

Heres a picture.

(can starting making now )

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!

 

[davenport]

that inlet looks very nice...

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

 

[Rick]

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.

^^^^:-) I like it I like it alot ^^^^

 

[magnet]

just wondering

Could someone explain what is meant by back purge and what is it purpose. Thanks. Magnet

 

[the snooper]

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

Thanx for that Atb Magnet.

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

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

 

[Tom C]

No you just use argon

 

[skrall]

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
Steve.

Manifold

Wow that some crazy pipe system can see some real time spent there. Looks real nice Vernon

 

[Rick]

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.
