Hi guys this is James from BMC
Thanks for the nice compliments on my new product. That is the first and therefore is a prototype with lots of improvements to be made.

I was linked here by Savington and made aware of the need of some quality high performance products in the Miata world.

Now let me introduce my company.

BMCRace is a family owned and operated business and has been around since 01.
We are currently outfitted with 3 HAAS CNC Vertical Mills and 1 HAAS CNC Lathe. We will be taking delivery of our new Motoman HP20-6 Robotic Tig Center by August 14th. We are currently taking a step into high production intake manifold fabrication (thus the robotic welder) and are looking for new markets. We also provide our services to supplement other companies as well.

BMC is owned and operated by
Sam Goertz (my father)
Gretechen Goertz (my mother)
James Goertz (me)
Louzee Banaga (my girlfriend and future wifey)
and shop mascots Duke and Toby (black lab and laso apso)

We would be very interested in doing some intake manifolds for the Mazda world and would prefer to find someone who would be willing to market and sell them for us as we prefer to have others sell our product line so that we can keep things on a higher production level.


Thanks
-James

Now thats how a new members first post should be. Welcome. Can I has intake manifold please

BMCRace

Design and production won't really take that long.
To get things moving we pretty much need to get hold of a factory intake manifold and in contact with someone knowledgeable of Miata

We take the factory manifold and design the head flange and anything else that might be a requirement (air sensors or whatever). Then we just need someone to measure around in a car and let us know of clearances and anything else we may need to be aware of. From there I begin 3d design of the parts and have things verified by set Miata Guru and we move on to production with 1 prototype piece and then the final production product.

Whoever is willing to be my helper in this project will get a substantial price reduction for helping us to develop a new product (this could be as much as free to this person depending on how things move). Right now things are grim for most industries but with a little ambition I believe it is a good time to move onto new markets and get R&D work done while things are slow.

Also I prefer not to use up my welcome on this forum as I know I am basically advertising right now, I would love to be a sponsor here and make a nice contribution if we can all work together on this. Please don't remove my threads or anything as we try to make progress, I am low on funds right now for advertising due to other investments however I know things will come around..

Thanks

James,

Can you put your location in your profile? No doubt there's someone nearby that wants a shiny manifold at a deep discount for helping you.

If you are in/near Chicago I have a Miata just sitting in my garage you can keep until I get home in December..

Welcome to BMC Racing Products - Welcome to BMC Racing Products
281 Area Code is out of Houston, Tx.

James, there are some inherent design compromises with the various OEM Miata intake manifolds... packaging and no consideration for forced induction... as you would expect. This community has been waiting for a long time for some "production level" competition in the manufature of aftermarket intake manifolds in particular. There are quite a few one-off designs and a Bell Engineering (BEGi) should release the first true production plug&play aftermarket IM for the Miata very shortly.

There are 2 basic engines, a 1.6litre (90-93) and 1.8litre(94-05) that use different IM flanges. At some year, the 1.8 cars also had EGR.

I think the market around here are guys looking to push 250-350whp with somewhere between 15-30psi. Over that amount of power, and a dedicated design would be required. There should be consideration for using the stock throttle body and an aftermarket BBK one (I think a certain aftermarket model for 5.0 Mustangs is favored). It would need a bracket to exactly mate up with the stock throttle cable attachment, and several vaccum ports at factory locations.

I can send you a 1.6 manifold tomorrow and offer my time with anything else you would need.

Thanks.

Do yall know if the 1.6 and 1.8 have the same port spacings at the head?

The way the manifolds are built they are all modular and if they were spaced the same it would make production alot smoother. Basically it is as simple as unbolting one flange and bolting on another, this would also potentially be a nice feature for anyone wishing to upgrade their motor, the manifold would only need a minor change...

As to the throttle cable bracket and what not, that is easily replicated as long as my source for replication is complete (thus I prefer a factory manifold). To clean up the look, if possible, I prefer to relocate all vacuum ports to the bottom side of the plenums just to give a cleaner "shaved" appearance.

As to Throttle Body options that is pretty simple, I basically leave that option up to the end user and weld the flange that will fit his/her application.

BMCRace

Because I don't have enough post here yet it is giving me some problems for getting back to some peoples pm's, however some are going through fine. Feel free to email me at sales@bmcrace.com if you find yourself not getting any pm back as this is probably the problem.

We are serious about developing this product and we intend on moving swiftly. After I receive a factory manifold and get all necessary drawings made (flanges, etc) I will begin 3d design and begin to update with progress pictures.

As to design things can be quite complex or quite simple

Here is my budget design I am currently working on for the Honda guys.
The velocity stacks are raised .5" off the floor in this design so to not interfere with the threaded holes for the modular design, this also gives us the ability to run a larger velocity stack aswell. Also when the stacks are raised in a manner such as this is does a good job at encouraging air into the the first 2 cylinders (these 2 cylinders are typically starved in all typical log style intake manifolds)






This plenum would be built from Ross D Shaped extrusion, we would machine each oval velocity stack from 1" 6061 t6 and precision machine the plenum floor for the stacks to fit into and the threaded holes. There would only be 6 welds in this entire manifold design, the throttle body flange, the end cap and the 4 velocity stacks. The end product would be something very similar to:



Although not as elaborate this manifold will still produce great power while remaining budget friendly (something this economy needs right now)
My plan is for this style of manifold would run for around $600 and that price includes matching fuel rail and hardware.

BMCRace

As to our machining capabilities and qualities here are a few pictures of a 100% billet dodge viper manifold we are in the process of building for a personal friend.






The ports must still be opened up inside the plenum, the top cap is almost finished, also we still need to machine the velocity stacks that bolt to the ports inside the plenum (this is also a modular design by varying velocity stack lengths inside the plenum)

BMCrace: go ahead and post a few more quick posts to get up to 10 posts so you can send PMs. I'm going to allow it since there's a lot of interest here. Do what you can to keep interesting information public though!

And no, the port spacing on the 1.6 and 1.8 are different unfortunately.

Sorry to add this to the thread. But honestly guys, I wouldn't do business with him. He is saying he's reformed, but he has a history of not delivering and making lots of excuses. Saying he fixed all the issues and everyone over on HT knows that is BS.

I've been around Honda-tech for ages and remember it all going on back then.

Stick to supporting the current companies that support the Miata.

levnubhin

iTrader: (30)

Well that's not good. Lets give BMC a chance to rebut. As for giving current vendors a chance, if they would get off their asses (begi) and put something out with proven numbers then they would have buyers.

He'll say what he said on HT. That he resolved all the issues and all that stuff is water under the bridge. Anyone can say that though... doesn't mean its true. There is just no reason to give trust back to someone who isn't IMMEDIATLY local to you after they have proven themselves in the past to have problems.

I just would prefer to not watch you guys go through the same stuff others did in the past. Who knows, it might not happen badly... but why risk it?

Talk to BEGI on the phone. Call up Flipside. They will make stuff for you and you KNOW they are trustworthy, no past histories to worry about.

levnubhin

iTrader: (30)

What kind of problems have they had? If your talking about taking people's money and not delivering a product that's one thing. But are they really any worse then say Begi with shipping wrong parts, being slow as hell, shipping stuff that dosen't fit/work?

Give us more details.

BMC has been around for a long time, we supply flanges to numerous companies, many of which sell their products here on honda-tech.

When I was 18 I decided to open my own business up under the name JG-Fab which did get a stain on it for bad customer service. However nobody ever got scammed, yes there were some unaccepted able turn around times and some people had been refunded but everyone got what was fair in the end.

I had decided that I am not cut out to run a business on my own so I had taken a hiatus and worked for some other companies for about 2 years. I had been schooled in robotics and decided as the economy went under that I would be better off working with my family's company (BMC which is short for Boerner Manufacturing Company) to help them stay above and really help to rebuild and improve on my past mistakes and really make a turnaround.

So sue me if I am putting forth my best effort to turn a new leaf and try and become a better person. I am sure nobody else out there has ever made a mistake during their crazy years (18-21)...

BMC is a family run business, Mom, Pop, Son, and Girlfriend all make it up. If you want to burn on someone burn on me (James, JG-Fab) for being a dumb kid who thought he could run a business all on his own, but don't say anything about the rest as they had nothing to do with it (BMC). We have over $280,000 invested in our business and have just made a new investment with our robot which is going to put us well into the $350K+ range when it is fully setup and operational.
