Don't worry, if you boost your Z there are many options for $3k excuses.

Phunk, IF for some reason I decide to build my motor in June when the TT's will be installed, would you build me one of these????

You can fill out an application and mail it in with the $75 application fee. You will hear back from us within 4 weeks *if* you're found to be a qualified candidate. From here, non-refundable 50% deposits are collected. Then applications will be put into a second then third round of eliminations. The final contestant will receive a manifold within 12 weeks. :rofl2:

But really, these will be available for ordering but production on them will be super slow for the time being. Once we compile the list of custom modifications necessary to install one of these, I think a lot of the buyer interest will fade.

This looks like a hunting application for an elk hunt I applied for in a western state last year. :rofl2:

I wish I could get one of these. I just come by every now and then to drool over it. I wish they were ready to go. This would be a done deal.

Felix 808 12-05-2018 02:46 PM

Wow very nice Charles as always :tup: I missed this in my catch-up post reading (making up a lot of lost time).

Interesting location for the throttle bodies though, I would think you would be absorbing a lot of heat off the radiator. Looking forward to seeing more.

Here is the last pics I was given of the customers car that is using the intake in the original post.

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?

Question. Will that manifold fit under a stock hood?

phunk 12-05-2018 03:11 PM

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.

We could make an arrangement so long as you are cool with the way we do the intakes... which is: non-refundable material cost deposit, then... anxiously wait and just when you're about to think we left the country with your money, your intake is done. But this might not take as long as they used to. My old business partner whom I do the intake manifold projects with has been setting up his own machine shop and our turnaround time will probably be quicker than it used to be now.

It fits under a Seibon hood which, as far as I can tell, follows the exterior skin surface very closely. The Seibon hood has much less webbing structure to its underside, and I do not know if that webbing on the stock hood will clear or if it needs to be removed.

So far, hood clearance for the intake and throttles doesnt really seem to be a problem at all. Due to the slope at the front of the hood, I think the big question is, will we be able to get intake pipes on the throttles without having to crack the hood skin surface. I am pretty sure that the answer is "yes we can" but it will be probably sometime towards end of January before I can say we have done it.

FPenvy 12-06-2018 07:20 AM

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

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.

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.

cv129 12-28-2018 02:23 PM

This manifold looks like something out of a Pagani or Singer

FPenvy 12-28-2018 02:24 PM

:yum:

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.

We are interested in working with a R35 builder to construct one of these manifolds for them. If you run into anyone who would be interested, send them our way. No GT-R tax (for the first one :roflpuke2: )

Jinxx 12-28-2018 05:09 PM

I am curious...with the throttle bodies in the front you would have to have 90 degree couplers there and another set of 90 degree couplers to get down into the intercooler ....wouldn’t they be more restrictive to the flow than the OEM manifold ...even with a NA setup with filters located there the 90 degree bend would have to restrict flow over the OEM set up.

phunk 12-28-2018 05:19 PM

We wont have any 90s we will be going straight forward into the top of the intercooler.

But if someone did want to put elbows on there, its not really going to make a difference. Your average turbo system has tons of 90 degree bends including the compressor housing outlets, inside the intercooler end tanks to enter the core, and all the several feet of piping to get around the core support. You could most likely end up without any more bending than the stock location throttles if you plan your pipes well, possibly even less bends. But the way we are using it, we will have eliminated several bends and at least 4 feet of charge piping, if not closer to 6 feet.

Attached some examples of our DE billet manifolds in use.

Spooler 12-28-2018 05:27 PM

Those pictures make sense. Just a redo of the intercooler for the piping to come out the top.
