Awesome -- remember -- make sure they understand that the resonance chamber has to seal completely to the OEM bumper ducting.

If it's open in anyway, then it's unlikely to shield heat effectively, and that is a key goal here, as well as improving airflow.

Also, curious to see if they can work out a cone filter to mate to the bellmouth or whether a panel filter will be best (if so, will be similar to an improvement on the old ARC airbox design).

Please keep me posted! Thanks for getting involved! :tiphat:

after reading up on velocity stacks I get where this is going and the idea makes sense to me now. Also not having to take the entire front bumper off to clean air filters would be really nice.

Would it be a good idea to get some intake air temp measurements to see if it's actually doing any heat shielding? Might be a good comparison to do vs the G3's.

Interesting idea. Not a lot of space to work with by the airbox(s) though. Maybe something like this, but with the concept you're describing.

Bingo! Exactly what I'm thinking :tiphat:

Some info on elliptical velocity stacks here http://www.datsun510.com/bbmail/2008-2/5816.html

So we're talking a potential improvement in airflow of 20%, all else being equal.

That sounds worth building a prototype to me.

I'm all for that. Phase 1 is prototype and compare and contrast with the smooth tubes + K&N on factory airbox -- if it can't out flow that, then who cares?


There's exact pics (minus the 90* bend to secondary pipe+filter) of what I am thinking in the link in first post.

Otherwise, similar to that, but sealing completely with OEM ducting rather than open like the ARC box, and of course the big CNC'd velocity stack inside.

Well, that's the idea anyway -- what there is or isn't room for is yet to be determined...

Dude, that picture looks sick.

Yup, that's what I was thinking. This would be something I'd definitely be interested in. It can't cost a more than the current CAI offerings like the Gen 3's though.

:iagree: Yeah anything more than that is overpriced anyways for potentially very minimal gains if any.

After reading up on velocity stacks a little bit (ok I just read the wiki page :p) this looks to be promising :tup:

^^^ Yep -- the primary goal here is improved flow without sacrificing air temps, with the secondary goals of ease of installation and cleaning.

As to price -- I made a point of mentioning to Swift that it needs to come in around or cheaper than the G3's to be competitive, so we'll see what they can do.

But, yeah -- that thing is a work of art! If they make the plexiglass cover for us, we can admire the lovely work while it's installed.

The real question is whether a cone element can be mated to it or if they can just make a screen for a panel filter. Either should be fine -- guess we just have to see what they come up with.

I'm in for updates.

I always thought the velocity stacks on s2k's were awesome.

remember reading that preludes and s2000s were seeing huge improvements in pedal response.

Thats because the S2000 is a badass car.:tup:

Just got back from Swift Racing Technology... the shop is badass, and the cars were fricken awesome.. I was very impressed, they do excellent work. Everything from intakes, turbos to exhausts.. Really really cool stuff.. They'll be doing work on my Z, I cant wait. Its gonna be awesome.

^^^ Great!

A few more important details:

Before anything gets fabbed -

Diameter of the intake tube must match OEM otherwise tuning will absolutely be required; same for location and orientation of the MAF sensors. They're CNC'ing everything, so that shouldn't be hard to do (and they probably already know this... but never hurts to make sure).

After the prototype is made --

You will probably need to do 3 pulls for each run to see changes -- the ECU doesn't adjust immediately (true, even with tuning). There are other transient modifiers that take a few runs to "self-adjust".

Also, be sure to keep oil temps right around 200* F, not too much cooler or hotter, and do all runs in same gear (either 4th or 5th is fine).

I'm hoping you guys can find a dynojet, but really any dyno will do so long as baseline and Swift intake runs are done under same conditions.

If you can do it on a dynojet, please send me the drf's (actual datafiles) to jlitman@mail.usf.edu when you do the runs. I'll make detailed comparison graphs and post them.

Also, if you can get pics as the build of the prototype comes together that would be awesome! I can post those too if you like :tup:

Pics will be coming when we start, we're still a little bit of time away from touching the car, soo everyone please be patient. I gotta get the car back to stock before we even do anything.

So you've found an excuse to now uninstall the mods that you actually managed to install on your car? Trollolololing :stirthepot:

nope... i found every reason to uninstall everything to get YOU on the track soo now Im guaranteed to dust that little automatic Z you got...

All right fellas, thanks to Jordo, I got the OEM air tubes, and filters.. gotta get them installed, and hopefully Bobo can square me away with the OEM exhaust.

Just spoke with Swift -- looks like they are on board with the way I am envisioning the intake design. Project is very much underway :tup:

I've stressed the importance of testing and comparing the new intake to competitors to validate its merits, so this should lead to some rigorous R&D to get the best possible design for us :tup:

Eastwest -- great job! Looking forward to more details as things come together :D

Interesting, subd

Things I would be looking for:

air flow
gains
heat soak
sound
throttle response
ease of filter maintenance
hydro lock
cost

Is it plug n play ? or tune required?

We'll soon find out..I'll keep everyone posted!

This is pretty cool. Any updates?

Nope, not yet. The shop is pretty busy, we'll know something soon. Stay tuned.

:tup:

updates?

Nothing yet.. I need to find a person in the area with an unmodded Z to have them run a dyno on it.. for a baseline. I REALLY dont want to pull of all my parts just to reinstall them.

i have non modded z

Honestly, you should probably just let someone else (who's already stock) take your spot with this project. Pretty much useless to use someone else's baseline dyno and then your dyno with other mods. It would prove nothing.

yeah, man, Im starting to think you're right.

Anyone up for this? Lets get this going again! :tup:

Im sorry Jordo.. I'll be sending your parts back tomorrow.

No worries, brother -- I appreciate your time on this :tup:

Im surprised, they didnt try to get ahold of me, I went by there a couple times, and could never get ahold of Muhammad. I dont know. Im not sure what was up.

I think once we find a new test car I'll follow up a bit more.

BTW, someone on here had custom bellmouths mounted to his gen 3's (not sure if spherical or elliptical) and he claimed something like another 8 whp over what the gen 3's made on their own -- that's very promising in terms of what to expect for this design.

Do you have a link to that info/thread?

I'll see if I can find it -- the guy recently sold off the parts -- saw mention of it in a FS thread.

why? did they work too well or something? :icon14:

Maybe he's selling the Z?

This -- it was a part out thread... which I can't seem to find :icon14:

EDIT: Found it. He said an extra 5-6

Still very encouraging!
