I've been playing around with SolidWorks trying to make a ramhorn-type manifold that will fit in the Rio. Not for my car, but there has been some interest. This design is all sch10 1.25" pipe, standard bend radius.



The collector has pipe splayed at 15° in the two axes. I think this is the common collector type. Flange is T3. Head flange is Kia Mi-Tech (A6).




A shot from underneath into the collector. If only I could make the collector look like this in real life?




Just for fun, the draft design of my current manifold.




And, comparison of the relative sizes.



Just for spacial reference, the log manifold in "real life".


Discussion:

I know the pipes aren't a true equal-length, but the outer runners also have a lot fewer bends. What do you think of the design?

Okay. After looking at the manifold I decided it looked too much like a SSAC manifold. Here is a Mi_tech ramhorn:



Thanks to Spooled Performance for the picture that I copied.



I think that is better than the first design. Tighter, too. Too bad I would need 13 els to make it. That would get expensive.


The beauty of SolidWorks? After I designed the manifold, I know exactly what length to cut the straights, what angles I need on the non-90° bends, and can figure out if there is any interference. I love technology.

 

I'll take the lack of comment as a good sign.

 

All I can say is where can i get that software??? I need that.

So you quit a design cause it looks like something else ?

What program is that by the way?

 

SolidWorks

it is great what technology can do. I hate AutoCad and all 2d first based drafting programs, they suck hardcore. Give me solidworks/inventor any day of the week.

 

solidworks

 

Solidworks is awesome software. So much better than autocad. you look like you are really good on solidworks.

 

yea, im using autocad now... i ******* hate it... solidworks should be installed soon

 

some one PM me please with info on how/where to get solidworks. I WANT IT, I NEED IT, I LUUUV IT.

Thank you. I use Catia and Inventor as well, but I prefer SolidWorks' constraining tools.

If you are a student you can buy a 1-year license for $90. If you aren't a student you either have to lie about being a student, pirate it, or spend the $5000 for the full license. Microsoft sells the software, so you can buy it at most University book stores, online and perhaps on Ebay.

Actually, to tell you the truth, I set out to design a ramhorn, but after making the first design I was like, "Wait, that's not a ramhorn, that's a SSAC manifold." Then after looking at pictures of real manifolds I saw where the bends were supposed to go and redesigned it. Note that the 2 designs use the same collector. Making a fully constrained collector with pipes in 4 seperate planes is somewhat difficult.

 

cool stuff. good to see solidworks users. heres my ram horn design... this is flanged for a D series.

Awsome guys, Only if I know how to even work solidworks, then that be awsome!

Any useful links to learn solidwork guys?

 

i went to school for this.

but if you have solidworks. it should come with a "online tutorial" which you can access if you go under the help menu in solidworks.

i've learned most of my stuff thru the online tutorial. my teacher sucked. ha.

 

theres nothing wrong with autocad, it just depends what your drawing. i'm a civil and structural draughtsman and i use auto cad alot and i think it's great, and you become extremly quick at using it.

i also use a 3D road design package called 12D for road and site design, i can say it is a pig of a thing compared to autocad. but if your talking about autocad as a 3d pakage, then i agree there, it's crap!

by the way, what is the hourly rate for an efficient soldiworks or even an autocad draughtsman in the states?

That's like saying..

Hammers are awesome, so much better than wrenches.

Autocad is one type of tool and Solidworks is another type of tool.. they are both well devoloped and very powerfull in their own way.

comments:

The "Full Race" manifold looks like you'd have to be carefull on how you weld it. You'd have to plan wich bends to weld first as to not make it hard to get to any other areas.

Great SW skills.

 

My process plan should make that easier. Basically the collector is going to remain 4 pieces until the very end. Tack it all together, break the collector apart and weld each primary independantly. Massage with prybar and torch, then reassemble, weld the head flange on, then clamp and weld together the collector. Should be 8 welds on the collector, 4 outside, 4 inside. The inside ones are definately going to be MIG. (I am thinking of getting a TIG with my refund)

Or maybe I will weld the collector together, then massage and weld on the head flange. Depends how it feels when it gets to that point. I am in the process of moving, though, so that will be at least a month away.

 

are you guys drawing those as one part in solidworks or are you drawing all the pieces individually and then assembling them?

i have quite a bit of solidworks a expierience but just not with any tubing with multiple bends and angles.

 

This is an assembly in solidworks.

Basically there are bends; nothing more than revolved concentric circles. Then there are flanges and straight pipes, which are simple extrudes. The collector is the most complex piece which uses reference planes and complex mirrored features.

Basically the trick to SolidWorks it knowing how to constrain parts together.

 

multiple bends and angles are easy man. Just find your line of revolution in space, and revolve it however many degrees you need. You could do it peice by peice, and it would make doing a BOM alot easier, not that it would be that hard with a simple manifold.

 

Solidworks kicks some serious ***... I'm sure there is better, but I don't have those programs, so they don't matter to me.

thanks for the tip, i got one tube put in!

 

Looks nice.

I don't like doing that kind of stuff in Soildworks, but I haven't used it very much. I find it more difficult to use, but then I did use Pro/E for over 4 years just doing advanced surfacing with aluminum castings and find it hard to move to Soildworks.

In Pro/E, I could make a manifold in one file, where as making an assembly in Solidworks would take a much longer time to do, for me at least.
