Project is coming nicely.

the piece in the photos posted above was scrapped. After I machine out most of the runners inside, I could see that the ports were just slightly off. Initial measurements were CLOSE but not dead on. I started a new one from scratch yesterday. This is much closer, within range for final hand porting. I will measure off it to dial in the next one even better.. but I will use this one.

Getting close to starting an official thread on this and asking for feedback, suggestions, concerns, etc... But not just yet. I want to get a little deeper in. For now, I have to set it aside until next weekend as I have fuel pump modules to design for late Vipers and the 90-95 300zx this week.

Looking good man! Keep it up!

I got pricing worked out for casting the runners. Its all good news there. Now I just have to finalize the design. I am thinking about 3D scanning the engine bay so that I can design around the strut bar more efficiently. Its just a question of how much I want to invest into this project before I can get anything back. Intake manifolds are risky too, because you can have a lot invested, and you wont know if they perform until its all done! If it doesnt, then you gotta do it again!

Maybe I should get one of those kickstarter campaigns going lol

if you could design a metal intake manifold i am willing to bet that it would be popular among everyone who wants to boost or run direct port nitrous

id pick one up just so i can do direct port nitrous as opposed to intake foggers

phunk 03-07-2014 04:22 PM

This manifold is already going to be an all metal construction.

I'll just post to stay subscribed on this.

Very interested, I hope you can arrange shipping to Australia in the future.

Any update on this? Are there any other companies out there that are developing a better intake manifold for us guys with boost?

phunk 04-04-2014 11:35 AM

This project is still expected to run well into summer 2014.

hc_416 04-04-2014 01:23 PM

Hopefully this will fit a g37!!

I am getting a lot of interest lately to move forward on the project.

+2!
I feel like 25lb of boost is going to leave me with a separation somewhere in this factory manifold.

Well something has changed: it actually crosses my mind again now.

Many other things this year have taken more time than I expected. It's no longer a standalone project, but something I am going to tackle as the first step in my big power build before pulling the motor. I have a new daily driver that will be mine in a couple weeks and I am thinking I will just retire the 370z until next year and start back up on the manifold.

Been getting pretty bored with my 370 lately... It's about time to either take it to the next phase or dump it... Been the exact same for 3 years now.

Let's hope for next stage, we all love us some new big power projects and products.

Just skip to the end to check in! Trust me, if there was anything worth posting, I would post it without being asked!

Rusty 08-09-2014 11:02 PM

Come on phunk, don't let us hangin'. :D

shaun66 08-10-2014 12:14 AM

Hope it comes to fruition one day! I wish there was a nice intake manifold option out there. How could a twin turbo 370z get boring!? I think you need to turn up the boost :stirthepot:

phunk 08-10-2014 06:13 PM

The constant traction issues and the lack of standalone engine management are what make me second guess my thoughts on building the car versus returning it to stock and trading it in before I cross the big line.

To just do the pistons and rods and tune it for higher boost isnt my concern in moving forward. Its the extra $4000 or so to convert it to built HR heads so I can use a standalone EMS (another $2000+), and i would still be left with a car that is non-competitive in its power class due to some of the worst rear tire grip available. To correct it seems would take another few thousand in building a new rear suspension system (tubular crossmember and all new arms/angles, etc), or retrofitting something off another car.

So there's a lot of hesitation I have, and I have to weigh it out. I originally planned to have already done the build, but now I have been second guessing the purpose to it for a while. Most likely, I will just end up doing it... there arent any other cars below $100,000 that interest me much. Honestly I have been sort of hoping to get some word on what the next Z will be, or if it will be. It could have a big impact on my decision making.

wstar 08-10-2014 09:31 PM

You're the first I've heard talk about rear traction problems due to suspension design. Is this something specific to Auto-X scenarios or something?

phunk 08-10-2014 10:10 PM

full throttle acceleration in straight line scenarios is what I am referring to.

Our suspension extremely aggressively cambers negative with rear squat. Terrible for putting down high horsepower.

G37sHKS 08-11-2014 02:11 AM

Our chassis is not that bad.

did you ride Camaro, CTS-V, Corvette, CL63, Shelby.. and many more that skipped my mind.

I've ridden all and their chassis are worse.
Im not saying our chassis is great but comn, its not that bad either, for $40k what else you want to expect?

it already got a better suspension design than the cars I posted above with half the price tag.

Read his post again. He didn't say the chassis was bad, he's saying the suspension is designed to induce negative camber on squatting which happens on heavy acceleration, especially if you're lowered. That's what needs to be redesigned.

All the cars you mentioned have a lot better straight line traction than our platforms.
