Recommend a free CAD Viewer

[canucksafari]

I found a CAD drawing for a turbo manifold, but I don't have CAD. Can anyone recommend a free CAD viewer program which would allow me to print?

[MARCIN]

e-mail it to me and i will print for you and bring it to the meeting.

I use solid works.

free viewer here: eDrawings Viewer

SolidWorks :: Free CAD Software Downloads from SolidWorks

Solidworks? Pff....get with the times, its Inventor now baby!

And this is the link I believe Marcin was trying to give you AutoCAD Viewer, DWG Viewer, DXF Viewer, Free Download eDrawings viewer

[Enigma]

You could email it to me as well John, and I can save it and send it back to you as a PDF or something.

Congratulations Enigma: you are our new CC software director!
Now, get busy and actually get some work done....

Thanks Marcin and Jeff. Jeff, I downloaded the program and Marcin I sent you the file for printing. I am hoping that it will give me a template for the gasket and manifold:


I had hoped to get other cad files for the design but only can find pics with no measurments. Maybe these pics are enough for a shop to give me an estimate and put one together?

or you can try this out:
progeSOFT: progeCAD Smart 2008
this is exactly the same as AutoCad, same functions, same features (actually more features) works fully with any AutoCad templates and reads all Cad files and makes changes and new ones just like Cad. Best part is that it's FREE!!!!
just register it for personal use and you're done! Not business, because then you have to buy their professional version.
Also if all you want is a Cad viewer then use this:
progeSOFT: Products catalog but I don't think they have a free version any more.
I've used it for a long time now and it works great.
Happy playing

I use to spend thousands a year for all the license fees for autocad, softdesk, LDD,etc
not bad for free
anyone want to buy a 3' wide plotter? you can use it to print out full size patterns

[Mud_Guppie]

you want equal length flowing tubes

[canucksafari]

I suppose that the degree of the bends will also have as much of an influence on air flow as the different length of the tubes, no?

That would be an issue in a different engine then yours, diesels are a bit different then gassers and little things like a header don't make as much of a difference on them as they do in a gasser - due to different pressures and RPM range. If you look at gas race engines the proper headers have all pipes almost equal length, sometimes they need some more bends to fit them in there but the lengths to where it combines are the same. There it is noticeable, also the engines are balanced, and cranked to the max where every little detail can mean a difference of horse power - here you don't have that issue. IMHO
I went from the factory exhaust (2 1/2 at engine to 2 by the tail pipe), cut it in half and went 3" all the way, I didn't notice any significant difference.

I was wondering about that Mat because the aftermarket cast turbo manifolds have the flange in the centre. Pressures wouldn't be perfectly balanced there either.

that's the reason why headers are usually better (not always though)
I'd be more worried about heat build up in the tight bends. I doubt tubing can be bent that tight

The line drawing makes it look like it was designed to be built from sched 40 weld ells and pipe.

Here's what Bruce posted for a similar header built for a 3B post 34:

Finished products Something tells me the shiney one costs more...

[Fantom]

when it comes to headers it's all welded sections due to the radius, I still don't know how they manage to do turns that tight on those either. The weld on Schedual 40 90s I picked up have an 1 1/2" radius, on a pipe that size the bender they use must be amazing.

[MARCIN]

I got the two parts modeled and now have full control over them, whats next John? pipe routing?. let me know, as I already have 5 min into his project.

[Fantom]

is that what you do at work all day? build weapons of mass destruction and manifold drawings

I wonder how far off the port spacing on a single turbo skyline would be. Find one from someone upgrading theirs to twin turbo setup. Should be easy enough to find take offs in Richmond. Then you'd just need to have the flange for the head cut and some tweeking to match the tubes up .

Interesting idea Martin. I will check that out. I know a few guys who should be able to give me the measurments.


Marcin, you have me a bit lost. Do you mean you already drew up a plan for the whole thing just from the pics? Thanks.

[MARCIN]

John, i just got the two flanges, header and turbo output, the drawing only included those two. to model the whole part we need more info. ie position of the input flange for the turbo, its angle and distance from the header flange.
with that info we can start routing the pipes.
