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 ??

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................

phunk 01-16-2014 09:47 PM

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.

G37sHKS 01-16-2014 10:48 PM

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
