ONLY 1000 bucks for a rapid prototype.
And roughly $2100 to have it cnc'd.

SO, i think ill be buying a chunk of aluminum and getting out the dremel and bandsaw.
Also talked about casting then machining. I would have to design special jaws/mounts for the cnc machine then. SUPER.

TAZ, can you give me any advice here. maybe how much costs would go down for a production of a hundred, etc... Any buyers. Would people be willing to pay 150 bucks for a tbi base?

I knew it would cost money, but not that much.

 

That's a little steep man! I could buy a whole LT1 for the RS for that much. Anyways, I'm interested in knowing what you are planning on building...

Later

 

needless to say, im not spending that kind of money. I have another lead on getting it made, so ill keep you all informed.

Coop. I redesigned the TBI.

 

lol. our class is gona do a contest and the best project gets turned into a rapid prototpe. I'm surprised its worth that much. what do you want? just a base or a whole new TBI?

 

Ive got the base redesigned, the injector pod is for now, I beleive a little bit out of my reach to plot/design. I have the idea of a new pod in my head and rough sketched on paper, but not on cad as of yet.

I have to start putting my base design into solid works asap because I am now talking to a friend of a friend that will do it for 60$ an hour, and teach me while doing it. He is a mechanical engineer and designs automated production robots for the automotive industry.

 

You should get your design patented.

 

Everything is already copywritten and I will probably have a bank notorize all of my drawing here in a couple days.

 

And, Taz
I was quoted 100 bucks an hour, at an inch an hour. my tbi is 2 1/2 inches tall.(machinable to oem height of 2 inches if needed for hood clearance)

 

Well if its all legal, could I see a sketch of your TB??

 

No offense to anyone, but nobody here will see this unit until it is either built/tested, and or patent pending.

Sorry, all I can do is tell you features which are listed in my post https://www.thirdgen.org/messgboard/...ML/000214.html

Take my word for it, I have taken all things into consideration. Incl. cfm rate, injector spray, later pod redesign, iac - egr problems, spacers, aftermarket manifolds, ease of installation, cost, mass reproduction, appearence, materials, building techniques(cast/cnc/etc) screw/bolt sizes, aircleaner options, dual tbi setup options, throttle linkage options, manifold options, hood clearence options, blade redesign, and more...

Hopefully soon (within a month) I will be testing the prototype.

 

Wow, that seems relatively cheap. I had and entire rapide prototype made of an intake for a race car at school. that was in the neighborhood or $15-20k. Luckily it was dontated becasue it was for a college. I would do just like you said though, buy a chunk of AL and mill it out. I would however have the spaghetti vacuum passages on the bottome CNC'd that would prolly be the way to go. Have that done first so that there is no special jaws required and the orientation really doesn't matter since it is stil a block and you can just change the orientation to match the vacuum passages. Just my opinion, based on my experience of rapid prototypes.

later,
Lars

First off, I never really assumed myself to have a need to have a rapid prototype made of this thing. It just doesnt seem needed. I mean, why spend that much money when you really dont absolutely have to. Now, if i were redesigning a short block V8, ok.

The passages arent that bad. They are all intersecting straight line bores. Not anything I would consider spagetti.
I figured I would just take the finished tbi and put it on a drill press and just adjust the tbi to it, all are 90deg intersections (parrallel to the faces of the tbi,)except for two on my design.

If I make this thing by hand first, its gona be a block, with bores, blades and vacuum lines. Not exactly what the final die-cast would be.
Ive even gona as far as thinking about clay modeling as a last resort and then making my own fired clay mold, which would be pretty much a rock mold. A glaze fire is almost twice that of the melting point of aluminium so I think a final,fired clay mold would hold up to pouring moltened aluminium into it. We'll see. and I'll of course, keep you all posted.
