CJ Motorsports VHR Intake Manifold
 

Saw these on Facebook and thought I could share with the community who missed it..

This is truly a master piece right there. Enjoy!!:tiphat:

Very cool!

Indeed. That manifold will complete the sexiness of your turbo kit!

Does look good. I dont think I have seen any boosted members running an aftermarket manifold yet though. I would love to get rid of the ugly *** stock one!

I thought so to until today when I saw this post:

looks sexy. hopefully it doesnt cost an arm and leg when it comes out. looking foward on seeing dyno results

I don't care if it is ugly or not. I am in for an aluminum intake manifold.

Charles needs to spill on this ... what size ITB kits fits ... 50mm, 52mm or 55mm ... I want the latter please - will these take Jenvey TB ??

Subb'd

You got that right! :D

This is what it could look like with ITB ...........

We played with the idea of putting the GT-R manifold on the car. Only because so many of you guys wanted it. I think the GT-R manifold is sort of lousy... well, as far any sort of upgrade that is. So I set a strict limit on how much Brandon and I would invest into it.

So we made a CNC fixture to hold the VHR lower runners in the CNC. We machined it down and down 1/4" at a time. The idea was to go down until the runners were closer to round than square, and than machine a thick plate to weld onto what was left that interpolated its way up to a GT-R manifold flange. This would have been a very cost effective way to do it, and the rules were that it had to use stock and CJM fuel rails so that it was ONLY a manifold project, not fuel system too.

Long story short, it was not possible to do it this way, LOL. It was almost embarrassing because initial assessments made it look so possible. Ill post pictures of it on FB one day. We wasted a brand new VHR lower collector and made a fixture that simulates the cylinder heads to bolt it down to.

So that was it. It was clear to me that it would be a poor decision to waste resources on putting a mediocre manifold somewhere that it doesn't belong.. rather than focusing those resources on a supreme manifold that fits right at home!

It will be several weeks before you see me say a whole lot more about this intake manifold. Initial steps are just being taken. I am waiting for foundry estimates on the cast runners. I have a material order going in tomorrow to start building the bottom flanges. Until the cast runners can exist, I am able to manufacture them through machining and fabrication.

This project has nothing to do with ITBs... but if the project is able to help people with ITB projects, I can sidestep a little. Perhaps some mild changes to the bottom flange I designed there would assist people with ITB projects.

That unit there bolts straight to the cylinder heads on whatever engine it is native. What I am building will be using the stock lower runners as its foundation. That piece has plenty beef to port larger and taper etc.

You have my full attention now Charles. I will not look at Kinetix again..........unless you scrap the project! And I am SURE that you can make this work since you and I have a similar setup. I will just have to be patient................

This will not be scrapped. I cant say that it might not evolve and change as it goes, but my car will be depending on this to exist! I just spec'd up the material a few hours ago so that I can order tomorrow. This is on the roll right now.

I really hope you don't scrap this manifold because its truly amazing design

This manifold will complete the masterpiece exhaust manifold from fast intentions.

masterpiece inlet, masterpiece outlet. the engine will not ask for more in million years

Sub'd !

Well, ordered enough material to make 6 prototypes. Or 5 mistakes and 1 prototype, or somewhere in between.

Cant wait to see more on this. Even if the gains are minimal I would want one for the looks especially if the price is reasonable. :tup: For trying to bring a new product out for our platform

The goal for this manifold is to make it the go-to manifold for the highest level of competition. Max RPM and extreme power. It will support major power and allow builders to take the platform into the competitive levels to put up against other platforms. I think that 2014 is going to yield some interesting builds, and that we are going to finally see the Z, for once, leave its relatively sad comfort zone (as far as HP and acceleration contest) and get out there and make a scene.

It will be hard to beat OEM tuned manifolds for bolt-on NA cars with stock redline... and its difficult to design a manifold with that goal in mind without lots of trial and error, and many versions. There will be only one way to see what this does for NA engines.

oooh finally, someone reliable working on this :)

Now that the cat is out of the bag, I am very anxious to get started on it. I wish I had some good stock here to start on it tonight... but I have to make some 350z triple pumps this weekend anyhow.

I don't know his forum name(or if he is even on this forum) but there is a marine who doesn't live too far off from me with a built twin turbo nismo with the kinetix preproduction intake manifold. The car looks badass with it.

It would definitely be better to run a metal intake manifold over a plastic one, I hear the stock manifold begins to swell at 16psi.

No doubt you will make it the best it can be. But the looks over ride the power.If I made this I'd be contacting the dealerships for manifold upgrades that they could sell and warranty when people buy. Just a random thoughtless idea.

No offense to anyone and it is still in the early stages but this is not a masterpiece(it's not bad tho). Due to a past NDA I am still in the time frame of, I cannot tell you why it isn't but it isn't and when they test it they may find out why, or they may not.

Edit:I'm sure it will look good tho and that tends to be what sells these more than performance for this crowd. Just polish it, engrave some neked ladys or something into it, maybe some fake CF accents, and throw a JDM or two on there and it will sell like wildfire.

If you indeed have an NDA with CJM, wouldn't this post by itself be a violation of it?

I will prove you completely wrong. I have built many intake manifolds for many engines. All of them a great success. My DE manifold made over 100rwhp at redline on a 700hp car. I dont know your intake manifold design qualifications, or who you know that failed at what... but i dont fail.

CJM has never once made a "cosmetic" product. If we make it, its going to perform. Its that simple.

Not with me... I have no idea who he is.

I'm interested in new manifold options. Do you think this will be as pricey as the GTM's GTR manifold kit? .... Probably too early to say anything yet is my guess.

Subbed!

Considering that the GTR manifold requires purchasing the GTR manifold, a new lower collector, new fuel rails, and a few hundred dollars or more in fuel lines... I am pretty sure we will come in lower.

not an nda with cjm different company. I have nothing to say on the gtr manifold swap that i havent previously in those threads, it's not a great performer and i'm sure this will out perform it. Just saying that it isn't a masterpiece, i qualify a "masterpiece of an intake manifold one that does things that are normaly seen as almost superstitious in performance quality. I meant no offense really i'm sure it will be a good manifold but not a masterpiece any time a compromise is made in design it automatically doesn't qualify. masterpieces of intake manifolds would be things like a hogan, or a dp manifold. fact for you a corvette c6r car has manifold openings the size of ONE of our throttles yet makes DOUBLE the horsepower that is a MASTERPIECE of a manifold to feed that engine and with the restrictors removed they make hundreds more horsepower.

The cosmetic comments also weren't a shot at you more at the fact that the prettiest new manifold is going to sell the best. Most of the guys who will throw down manifold money do it for looks not performance, over half of the cosworth de manifolds sold went to ostensibly show cars.

Look at the size of these inlets and remember this car had over 590whp yes there are only 2 inlets it is the tiny little silver piece in the bottom left that connects the 4"duct to the carbon fiber goodness for those that don't know

that manifold minus rails and injectors only weighed a few pounds too. and it went through MANY revisions before it hit the car and MANY more before it hit a track, and several more after that.

Edit: No need for this post.

Should have Trips remove his post for hyjacking... Not cool..

I hope one of those possible mistake wont actually be one..

as per my PM to you , I want one ! ;) *the flange...*

What are u Guys so pissed off about it isnt going to be the greatest manifold evah. Its not bad but it isnt going to be legendary. And cj the c6r manifold is more than carbon fiber plenums and u know that. Im just saying it isnt a "Masterpiece" half of it is a factory part that is plain crap.

I give trips more faith that he wont remove my post because it s relevant respectful and not bashing pm me with a valid reason why i should take it down and i will do it myself.

And power through restrictions really cj thats about the noobs thread isnt it. I put it in noob terms that effictively describe whats happening without posting a bunch of pages going into a deep technical explanation of everything that happens in a fi engine.

And yeah im sure youll charge less than c6r because you dont have a fleet of engineers squeezing every last bit of power out of it and you wont be spending hundreds of thousands of dollars on this rd its true its not bashing your making an affordable replacement piece. It wouldnt be affordable if you did.

If you make nicer manifolds than hogan how come they sell many times more than you, how come they are the go to guys for MANY motorsports teams and hundreds of drag cars. Unless you are talking about contruction, sheet metal manifolds dont appeal to everyone so you can say an all billet manifold would look nicer and be physically stronger.

Im not mad at your post and I don't see any reason why trips or any of the bosses should delete your posts.

The fact that CJ doesn't sell as much as other high brand company because of marketing if I assume right.

See, CJM never disappointed me on their products and this is actually a nice piece to look at compared to stock or any other aftermarket manifold available for this car up to date..

This conversation makes me feel like you guys have never talked to Charles over the phone (or maybe just to ask about something very specific). I while back I spoke with Charles extensively about the direction that I wanted to take my build and what parts/services I could enlist from him. So far, he is exceeding the request the I made of him a few years ago and should sell quite a bit of the parts that he used on his car if he chooses to allow them into production.

</off-topic>

Charles:

I may have to take you up on that offer of putting together a box/package, lol. You have a lot of parts that I would like installed on your build as well as coming up soon. Unfortunately, I am still waiting on my replacement radiator (if CSF decides that they will replace it). I just hope I can get back in the game before you start getting backed up with orders.

Purpose? I don't have an agenda nor do I need one. This is an open public forum and I am allowed to express my opinion within the rules set by the forum administrators. I responded to a comment that I know was inaccurate with a relevant respectful response that you clearly took the wrong way. Instead of bickering and saying you make the best manifolds ever, that when i just went to your website and checked wasn't even tested on an NA car and cost almost 3grand, why don't you actually try to explain and sell to me why this manifold is a

What actually makes this manifold the greatest or best possible manifold that can be made for a VHR. All i see is you are shortening the runners, adding velocity stacks and putting larger plenums on it which is basic stuff, and I'm assuming you have done rough heimholtz calculations and are applying common sense, anything else? where is the masterpiece?

Also if you are comparing hogan manifolds as a cobalt to your bugatti (which is a msterpiece) manifolds, what you are saying is you are only going to make a few, they are going to be incredibly expensive, heavily engineered, and they will be the industry performance benchmark, with accolades including multiple world records, and what all others will strive to be... I don't see that I see your manifolds as more of a good homemade pizza to hogans artisan chicago deep dish, while it is better than most take out pizza's, it isn't something you could live off of, thats why you make fuel components as your bread and butter, and hogans sells manifolds.
