So do you already have a mod list put together for the DD? I just picked up a 1996 240sx for DD and I will get a FT-86 for my newest DD when they come out :happydance:

Nice STi Mike!

Sorry, I don't have the answer to your question. You'll have to check with Sam on that, but I'm not even sure if he knows just yet. After all, we're still in the R&D stage on this one.

Me like!!!!!!!!

JB-370z 02-03-2011 10:15 PM
This kind of data is awesome, most places dont release this kinda info, wait.............most places don't have this kinda R&D behind their products cough cough. This one part is for sure going to have oem like technology backed behind the production of it. This part of the design on a high quality kit product does not come free these days.

The machines, that do these types of data analysis and the guys that operate them also don't work for free. Im glad there is a company devoted to my Nissan to the very last detail.

Awesome DD!

1slow370 02-04-2011 05:17 AM
eh just threw the Ti out there for the baller factor, glad to see it's slowly getting somewhere. if it's a thermal plastic are you going to be inserting brass thread inserts for the plenum to lower bolt's? If so might want to get two manifolds printed up quick or see if they can repair one because when you heat the brass insert to press it into the plastic it can pull loose and not really do anything. Trick is to get them hot enough but not too hot we do it at work in dark blue/gray nylon.

bullitt5897 02-04-2011 01:48 PM
I would love Titanium but I trust GTM's decision and I am anxiously awaiting the results of the final product the same as you guys :excited:

Vegitto-kun 02-04-2011 02:40 PM
I kinda want this to be finished soon but on the other hand I hope the car will be at GTM when I come to america this year. :roflpuke2:

1slow370 02-05-2011 03:14 AM
it's just a prototype so i'm sure it will be alluminum eventually. It costs a lot to have this kind of stuff printed, i have heard prices on these machines can go from around 60$ per cu.in. to over 100 for metals so it isn't really a mass production thing.

it's sometime next year and the crickets is a chirpin....

Geez I should have checked this thread sooner :facepalm:

seriously we dont need instigating little pricks in this thread... If you want to start crap go else where... if you were actually reading this thread and actually following this build you would know I am allowing GTM to do product development on this car... Take a chill pill and actually educate yourself on the build... if you continue the instigating quips you can leave.

Here's an update on our intake manifold. We've been working with a Rapid Prototyping company, and it's taking a little longer than we anticipated. Nevertheless, here are some images generated from the scanning software. One of the biggest advantages of this process is the ability to verify air flow through the intake and make any necessary changes to the design in CAD to eliminate any restrictions. The design has been finalized and is being "grown" as we speak. According to the company we are working with, we should have the prototype in hand next week. At that time, we will be test fitting the lower manifold in conjunction with the GT-R upper intake plenum and performing some initial dyno testing to verify the design.

Some of you familiar with rapid prototyping have suggested growing the part in titanium. Unfortunately, this part is physically too large to print using an iterative metal laser sintering process. Not to mention that even if their "printer" was large enough, it would take over a month just to print! Given that people want to see this car finished, we found the timeframe unacceptable. Therefore, we will be using a new type of high temperature plastic developed to be tested in harsh operating conditions (such as a forced induction manifold). Although we were skeptical of using plastic on this part of the engine, the material specifications convinced us that it is well within operating parameters.

We have several cars that we will be testing this manifold setup on: a stock 370z (to see what effect this manifold has on an NA application), a GTM supercharged 370z, and of course the White Dragon. Given that we can make adjustments to things like runner diameter and length in CAD, we can fine tune the performance to suit the particular application.

Also, it has been our experience that the factory HR/VHR upper intake plenum starts having issues with over 15psi of boost and 700whp (afterall it was designed for an NA application). Using our lower intake plenum in conjunction with the GT-R upper intake plenum will allow for more boost and more power.

Enough technobabble, here are some pics:
What sorts of changes are you guys looking to make? Is the goal to raise peak torque higher in the RPM range? It would be awesome if you could keep it flat after 5500 RPM where it really starts to plummet.

Well isn't the purpose of that to allow for the GTR manifold to be fited on? I know the reason there going with the GTR one is because the stock one they feel wont be able to handle the boost pressure, atleast thats what i got out of it.

bullitt5897 02-07-2011 08:23 PM
The stock one will work with mild applications. However, when pushing higher boost pressures the stock unit was not designed for it becomes terribly inefficient and there for we took on the GTR intake manifold as a readily available solution that not only looks great but was designed with FI in mind. The lower intake manifold is simply to allow the VQ motor to mount the GTR intake manifold seeing as the runner positions are reversed. GTM has taken into consideration their own improvements and what performance they would like to see out of this unit.

Jordo! 02-07-2011 10:59 PM
^^^ Hmmm. Bigger diameter but shorter runners would really allow it to breathe while also raising where peak torque is made. In conjunction with a VVEL controller to maintain low speed torque with the new set up, this could really be an awesome NA mod... :yum:

I was playing with this calculator

http://www.wallaceracing.com/runnertorquecalc.php

Supposedly the engine makes peak torque at 5.2K RPM. Assuming the displacement is 225 ci (is that correct?), am I right that the stock IM has an Intake runner area around 2.21 sq inches and length around 16.15 inches long (from valve head to plenum).

If so, it would be cool to raise peak torque up around 6000 -- that would seriously raise peak power potnetial -- awesome for all out drag cars, but good for the street too, especially if VVEL can maintain low speed torque.

According to the calculator, for peak torque at 6K:

Optimum Intake runner area 2.55 square inches (calculated)
Optimum Intake Length 14.00 inches long (from valve head to plenum).

DIGItonium 02-08-2011 12:00 AM
Just to double-check, is this plastic design chosen for economical purpose as well? IIRC, a brand new VR38 lower intake manifold runs for around $500. I wonder if a group buy would help cope with the development costs.

Also, assuming we'll be using the standard VQ37 gasket for the manifold to meet with the head and VR38 gasket for the intake plenum. Are there benefits to using a thermal gasket?

RCZ 02-08-2011 10:31 AM
Damn, impressive GTM. This is at another level! It's pretty amazing to see this kind of technology, granted it has become more accessible as of late, being used in the development of products for this market range. Big thumbs up.

What's next? fluid dynamics? gonna get adrian newey to design a body kit?

Z eliminator 02-08-2011 10:54 AM
Sounds great , now add the Motordyne intake manifold with the VVEL and the N/A car would really haul. The Motordyne work very well on my car.

lol. i am just picking on elim. he knowes me

Z eliminator 02-08-2011 11:13 AM
Let the truth me spoken " Shumby if you ever get to go for a ride in my N/A 370 with Bolts ons it would give your G a run for its life in the 1/4 mile. "
Ask Sizbe what my car runs like ask him to show you the video of me and 550 rwhp SC mustang.
Now if your wife drove the car she would give me a better run.
Your best friend z.

why the motordyne intake. the GT-R one is probably better.

Il say it again I hope that the car is still at GTM around june/july so I cant see it :roflpuke2:

Z eliminator 02-08-2011 06:52 PM
Because i have one, and i want to see how it works with the SC.

that won't work. The purpose of this piece is to allow the GTR upper to fit.

It will be hit or miss on this one. the purpose of this lower intake manifold while increasing performance is to allow VQHR motors to fit the GTR intake manifold which has runners in reverse pattern. Now if your motordyne intake is for a GTR it will probably fit if not... I doubt it.

Sibze 02-09-2011 07:57 AM
We should just buy GTR's haha
