What CNC parts do YOU want?
 
So here's the story. My brother, an ASE Master Tech of many years and a once ME student who converted to Finance, bought a Bridgeport knee mill and a Southbend lathe for recreational milling, harkening back to his days as an ME student.

Long story short he ended up using his mill to make money ... at this point making semi complex brackets for a laser welding company (if I remember the details right). The funds from this and potential future work has him in the process of buying a professional CNC mill. Right now he is negotiating with two different sellers about a Matsuura MC500V vertical machining center. The deference between the two available is negligible however he has already negotiated for other mills but those deals have fallen through due to my brother driving for a good deal.

What it all boils down to is this. With such a capable mill he is looking to do more work with it. He's a long time car nut and, being his younger brother, I am just as well.

I hope this post does not violate any of the rules pertaining to "no unapproved business posts" ... because at this point I'm not seeking to sell anything ... only ask the community what kinds of things they would like to see produced.

So to the community I pose this question. What things would you suggest he look into making? What products/solutions are not currently available or could be done better with CNC equipment?

Off the top of my head I've thought of two things:

A: water pump replacement plate ... allowing the installation of a remote pump (no more water pump cavitation and no double pulley needed)

B: CNC port jobs following popular porting profiles. Perfectly matched port openings and transitions into the runners from one iron the next FTW.


So what CNC parts do you guys want to see produced?

isnt that like the throttle body whats their face already makes?

AGreen 09-29-11 07:16 PM

An adapter plate to allow the use of a more COMMON (therefore less expensive when it breaks) and better operating idle air control valve. (for those of us with standalone ECUs)


Or how about a custom adapter plate for S4/S5 to T4 so you don't have to buy a new turbo manifold if you want to get a new turbo??


All these adapter plate ideas....

How about one for mating a turbo driveshaft to a non-turbo pinion flange?

a green, someone already makes an adaptor for a better iac.

yeah, and it sucks. please god make an adapter plate please god.

You could CNC some grooves for the coolant seals in peoples rotor housings ( where they belong ;) ) kinda aimed towards older rotaries, but still something that would be nice

So I see below postings about the idle air control adapter but can you find the one your talking about? is it still produced?

...

I take it you mean exhaust (turbo flange) adapter?

Also ... is there enough play to get an adapter between the pinion and shaft? ... keep in mind that something like that would have to be beefy.

SirCygnus 09-29-11 08:22 PM

i like how you are not even looking at my posts.

yours i didnt need to reply to ... because it's a good idea and I've already been looking at the bolt pattern of the t2 uim and pattern of mustang throttle bodies and even some other TBs

Yes.

1/4" steel plate should be sufficient, and yes, there is enough play. Remember that the driveshaft doesn't have to plunge very much like a live axle car does. I was going to make one, but decided that I'd better leave stuff like that do a machine shop with a little more precision. I couldn't get anyone nearby to do it, so I had a custom driveshaft made.

if you make this i will worship you.

misterstyx69 09-29-11 10:19 PM

How about a big bore TB that isn't a single 80 mm butterfly(like RW's is).
That will work with the S5 TPS or haltech Tps?

FCs4226 09-29-11 10:57 PM

i have a cnc mill mazak vqc 20/50 b for sell. for a real cheap price. p.m me or email ptran1226@gmail.com

gameova 09-29-11 11:11 PM

im with the guy above!! let me know

dude, thats why i want an adaptor plate. slap on almost any friggin TB you want with a haltech and most TB's have built in tps's. hell, lets just keep it GM so the shit is cheep

ya,Ok that'd work,,adapter plate special..! x2!

Built in TPS!?!? I like the sound of that... Self adjusting??

SirCygnus 09-30-11 06:36 AM

no not self adjusting, but you can adjust it in 5 secconds inside the haltech. plus, the TPS isnt really built in, but its built specifically to accept it, so we dont have to build no damn stupid brackets to jerry rig one to work with our TB.

i want flanges for s4 and s5 turbo that match the backplates so they can be used to make bellmouth downpipes. this will cure a majority of boost creep problems on stock turbo

RotaryEvolution 09-30-11 09:26 AM

i would like to see some more pulleys for the FC as there isn't a single fahionable kit out there, just some plain anodized black underdrives.

should also look into the outside door handles, the current ones made with pot metal break easily at the top point of the pivot. new OEM replacements won't be available forever and there is no aftermarket units.

Excellent idea!

Aaron Cake 09-30-11 09:53 AM

Why is everyone chasing bigger throttle bodies? And especially, on the stock manifold?

If the TPS is the only issue, CNC a bracket that allows a typical Ford or GM style TPS to be mounted.

Slapping on any single blade throttle body is going to cause more headaches in the tuning department than a flaky TPS ever would. And I will guarantee that you will never quite get that low load transition from idle to high throttle just right. Plus, it will completely kill runner and port velocity in the primary ports. You'll need about another 0.5 - 1mS of injector time to compensate. Also about 50% more accel pump.

All Mazda rotarys have used a staged throttle system since the '60s for a reason.

Pulley kit already out there for FC3S

+1
Though it would have to be pretty spaced out away from the engine to allow for turbo clearance. A to4b housing is good and all but fitting a bigger to4e housing on or better would be awesome :P
