thats only we're flat out for 6-9 months of the year. the 3 month spring slowdown with nothing but 4hr shop days makes up for it :approve:

Phantom, if you dont mind, I dont mind doing the prototype work.

I just started working again myself so it will be a month or so before I can tackle it but I bet I can get a working prototype before christmas.

I dont wanna sell shit though, I just want one for myself lol. Someone else can take it and run with it.

Sure, why not. I wanted this to be open to the community. PM me your e-mail, and send you a set of basic instruction and the files.

Wow, awesome job. I'm curious about how you build the model. Specifically, how do you accurately replicate the mating surfaces? Is it a matter of taking a lot of measurements with calipers? 3d scanner?

I have a large collection of measuring tools. Itll be nice.

when can i purchase this manifold?

when its made

You mean I can't pay extra for the spaceballs option and get my finished manifold before you finish it.

Yea I guess you can do that.

i want sex with CF manifiold damit

why not prototype it with sheetmetal? Seems like it would be way easier

I have a CF manifold, just not on my MS6.

I don't know how you ended up designing the velocity stacks, but there has been a lot of research on the topic and you should be able to find some 'ideal' shapes.

A lost wax method will probably give you the best results for fabrication but it won't be cheap.

One of my diplomas is in mechanical engineering Tool & Die (includes molds). A "lost wax" method would be perfect except that I would have to front the money for 1,000+ units.

My wife and I just dodged a bullet yesterday when we found out that we don't have to claim bankruptcy. Instead we are presenting an consumer proposal which will take 5 years to pay off and still ding our credit. The good news is that we will get back on our feet faster and we should have extra cash come the new year. So the delay is really not that long.

A lost wax method would also lock in one design, where as my method allows for a change in runner length, plenum size, inlet angle, without having to retool.

A sheet metal intake would be nice, but my design is on the high end of the difficulty scale to build. Yes it can be done but at a high cost. The welding on my design is kept to a minimum and is very simple (read: cheep).

Carbon fiber is cheep to work with in comparison to metal for a limited production run with complex shapes such as this manifold. CF is also very light not only keeping weight down but also reducing stress on the manifold. CF also doesn't conduct heat like metal does. So intake temps can be kept down.

As for the velocity stacks, I did a lot of research on them. Long vs. short, Taper effects on velocity, pressure, swirl ect. I tested around 15 different variations of the velocity stacks before landing on this one. The greatest benefit of this design is that the change in port shape from round to "square" cannot be achieved any smoother resulting in very smooth flow given the constraints. Ideally the best setup (in my opinion for smooth equal flow) would be an Individual throttle body setup into perfectly round runners... Obviously that's not possible for this engine.

I enjoy discussing this stuff. Keep it coming.

update :)

My wife and I have filed for a consumer proposal. (1 step away from bankruptcy). If the proposal goes through we should be on our feet again in a month or two. If not... well then we file for bankruptcy and move in with me parents. In which case I'll just release the plans as "open source" as I will no longer have a MS3. :(

Lets hope for option #1

Ill probably be contacting you sometime next month to design a mani for me, I have some ideas I wanna see that are pretty cool.

good luck with your credit phantom3! hope it works out for you

Sounds good.

I'm hoping... I'm tired of this shit.

Hope things start lookin up for you and your family!

phantom3, best of luck. i'm foreclosing but i switched banks and i'm getting back on my feet as well bro. hang in there

Thanks man. Our consumer proposal is going through right now. 95% chance it will be accepted.

Update:

Good news, as you may know (if not go back and read), my wife and I filed for a consumer proposal a while ago. Our largest creditor just approved the proposal (majority wins)! That means no mater what the other creditors say it's a go! (we still have to wait for the other creditors to vote. The latest the proposal will go through it Dec 21.

I'm planning on having a working prototype by the end of march (Moving and wedding in Jan).

That's great news man!!! Congrats!! Family always comes first... But this CF mani comes a REAL close second!!

Right on man. Glad everything is looking up for you bro.

but.....


....if for some strange reason the proposal still doesn't work.....I'm currently looking into the fight club method. I have the clothes, just need the soap. You are welcome to join on....;)

Nice, im still game for a cnc one. CF still seems like alot of trouble lol.

bump

David, am I still volunteered for this? Oh and what else did you volunteer me for? lol

This was made using lost wax.

CF intake manifold with injector ports

ummmm....

is this for the mzr?

you make your self?

is it on the car yet?

can I has one?

how much for an IM if you're willing to make another?...

thas a sick looking mani u got going on there.. good luck man!

I volunteer you for everything... lol

Nice work man, I thought the original design was for straight runners?

The design is still for straight runners... I dunno where those pics came from

Oh my bad, I thought that was a prototype.

I wish... not yet.

Yeah wtf! Wheres my main girdle! damnit wth... get ur ass in gear already yet!:biggthumpup:

i think phantom should start a paypal account, for everyone to pitch in to get a prototype going. ill sure as shit throw some money in. i do want a manifoldddddd!

glad to hear the good news phantom.

interesting pic with the wax lol

Ok, sorry there wasn't more of an explanation with the original pic. I was going to add something sooner but I've been really busy and really sick.

That mani is for a different engine - the cbr engine you can see between the middle 2 runners hooked up to the dynomite engine dyno. I was really surprised to hear you would have to front the cost for 1000+ units for lost wax since this was a one-off design. It also has a BOV built into the plenum for backfires - with the Haltech Platinum Sport 2000 all the spark plugs fire when you turn on the ecu so any time an intake valve is open you can get a pretty violent explosion. This shouldn't be as much of an issue if you stay 100% DI, but as soon as you add the port injection you have extra fuel sitting in the mani. Blowing apart a one-off carbon mani is expensive (don't ask me how I know) so I recommend you look into the BOV thing.

Speedsixxx - I'm way too busy to make one for the MZR right now, and the cost to make just one more would be too high to be worth it. This one is on a cbr powered tube frame car that weighs 430lbs.

Pics of said car please :)


Also, great point with the bov. With PI and crazy cams, backfires can def blow up an intake mani.
