CJM Billet Intake Manifold

phunk · 12-05-2018, 02:58 PM

We just finished up the second one last week for Justin Blackwells car (the 9 second stock engine car). We havent posted it yet because we are playing with custom engraving patterns on it. Maybe in a week or so we will show it off and let everyone decide if it looks any good or if we should just surface it all back down to normal billet machine look.

Well, will you sell me one?

This post shows the bottom of the bottom on the original versus the second one. Notice we cored out the bottom a bit to take out some weight. Doing this along with thinning out the side walls allows us to take a few pounds off the weight. Sorry the only pics I have of the bottom of the first unit were from test fitting our fuel rails to make sure it looked the same as in CAD.

This post is showing what i mean by thinning up the sidewalls. On the second manifold, we continued the nominal thickness down around the sides and up to the flange. It makes the flange around the outside really show itself... not as flattering in the rendering but in person it adds some really cool detail. It also makes the side ports for MAP sensor and vacuum ports more 3D and prominent.

One thing I think I failed to mention in the original post is that I did test fit the manifold with the strut bar. While it didnt fit immediately, by adding some spacers to the strut bar I was able to fit it and still close the hood. This snapshot taken from a video I posted of closing the hood on IG, the spacers are much thicker than necessary to clear the manifold, and the hood even still closes. Although, this was with a Seibon hood, and with a stock hood the strut bar spacers may cause interference without modifying the hood webbing structure.

One of these days I will probably machine some nice 1-piece spacers so that we can install the strut bar without it looking like its just floating on some hardware store spacers.

ooooo i wonder if this would work on a GT-R with a front mount turbo set up

Spooler · 12-06-2018, 11:24 AM

Phunk, I am going to wait until you get Justin's car finished. Once that happens we will go from there.

It was finished up today. We have no testing or data at this point. We will be running one this year on Justin's 370Z that ran the 9.91 @ 142 stock engine last fall. A custom engine build is in the works for the car.

So, the hood still closes. But once we start building the throttle tubes, some of the frame work under the hood skin will have to be cut out. But at least the hood skin will remain intact.

Its just so beautiful

We did finish Justins intake manifold. Now we can put his race engine in the car after we finish using the car for building final intercooler jigs for reproducing intercoolers off the car. I will get better pics of it soon. We made a billet camo pattern on the lid to break it up a little. We will probably do some camo theme on the valvecovers to match. The lightening modifications worked, its noticeably lighter to hold and wave around.

This manifold looks like something out of a Pagani or Singer

cant wait to see this all setup in the car with piping.

curious to see the pipe routing. this mani could make a splash in the GTR market especially with the big HP going front low mounted turbos.
