**original thread here**

Hey guys, I'm starting up a project. I'm tired of the lack of independent data associated with intake mods and am going to test as many different intake mods as I can get my hands on, in one concurrent session in order to keep the variables to a minimum.

I've always been fascinated in NA power since its so hard to attain on our cars. everything has to be working perfectly in sync in order to maximize output. I plan on doing a NA build eventually (I have the motor in pieces, 11:1 CR Weisco pistons, and its just waiting for time and money I don't have right now)

As I mentioned, I'm trying to remove all variables. This includes any bottlenecks in the stock motor that may cause the benefits of an intake to be masked.

My car right now: 06 G35 5AT with 44,XXX miles
- Z-Tube
- Ported and Poished Plenum Assembly down to the runners work thread
- Polished Throttle body scroll down for pics
- Thermal gaskets to lower plenum temps
- Coolant Bypass mod work thread
- Strup coated headers work thread
- Altered Atmosphere HiFlow Cats ** will replace with ART pipes **
- Bassani true dual exhaust with x-pipe
- Uprev Osiris

With this configuration, I believe I will be able to realize any gains to be had from the intake mods I test.

Here is what I had in mind for testing:
1 - 5/8 Spacer
2 - Stock air box with K&N Panel filter
3 - 06 revup airbox with K&N Panel filter (the one with the large velocity stack)
4 - JWT Pop Charger
5 - ??? what do you want to see ???

I plan on doing sound recordings for each setup in addition to data logging each of the runs to pull a/f ratios and other engine stats. And I will post dyno print outs of each one to tie it all together.

learned fuel settings will be cleared between each part (ecu reset,) the car will be strapped in the whole time, dynos will be back to back. I will start with the lower plenums, then spacers, and finish with intakes. which ever plenum and spacer make the most power will stay on for the intake testing. The car will start out with the stock air box and K&N panel paired with my ported and polished plenum as a baseline.

as per weapon-r:
I will be reseting the ECU by disconnecting the battery, not just clearing fuel settings.
I will give the intake a small learning period before the runs
I will give the engine a small cooldown period before the runs

"'duelper4mance' can get me on an AWD Mustang dyno for a $25 strap fee plus $15 per pull, or $85 an hour, whichever is cheaper."

I've already got:
- Motordyne ART Pipes (TrixR4kidz)
- Motordyne MRev2 Lower (duelper4mance)
- 5/16 Spacer (T3K_V35, duelper4mance)
- 5/8 Spacer
- K&N Panel
- JWT Pop charger
- The stock airbox
- 06 rev up box (T3K_V35)
- Stillen Intake (gmotion04)
- FuRookie SRI (martyg35) thread
- Tekada (platelock, older version)
- Tekada (AFE - new version, uses stock box)
- Weapon-R (not sure exactly what they are sending me)
- Top Speed intake (waijai and Aaron from topspeed)

I might get:
- New Prototype intake (SxExCx)

I'm still in need of:
- whatever else you think needs testing
- donations for to help cover dyno fee

I've Emailed the following companies asking to dyno their intake:
R2C - http://www.r2cperformance.com/ - responded, not likely
Fujita - http://www.f5air.com/ - no response yet
AEM - http://www.aemintakes.com/ - no response yet
Injen - http://www.injen.com/ - no response yet
Takeda - http://wwww.afepower.com/ - responded, received intake
K&N - http://www.knfilters.com/ - no response
HKS - http://www.hksusa.com/ - no response
Weapon-R - http://weapon-r.com - repsponded, shipping out soon
Stillen - http://www.stillen.com - no response
Kinetix - http://www.kinetixracing.com/ - no response



what do you think? is this something you'd be interested in seeing?

I'd like to see the difference between paper and K&N panel with no other changes.

 

I would like to see some of the plenums that are claiming tons of different gains like kintix V+, Velocity and others like those

 

a thermal spacer will give you more gains with a stock plenum then most aftermarket...theres a few threads where they have dyno'ed with the FI guys who thought it would make a difference and didnt.

 

In for results.

 

Subscribed, good luck.

Are you planning on removing your current mods? These might affect the results one way or another, specially the tuning...

 

I'm thinking my current mods will allow the intakes to shine or fail as there is no other big stock bottleneck to hold them back. So I will be leaving mods in place, I could care less what all these intakes do on a stock G, that was never my goal.

sorta good news guys, AFE (takeda) got back to me with this

"Rob,

Let me see if I can get this cleared for you.

Honestly, I think your wasting your time. I'm a details guy and over the years numerous people have dynoed all sorts of intakes and provided before and afters. Any intake will realistically net you no more than 5whp on a Dynojet with the hood up and cool air being funneled in. Most results I've seen are inconclusive and well within the range of run to run variance. With the hood closed and under daily driving conditions, a VQ can loose significant power with an open intake (ie pop style) due to excessively high underhood temps. All intakes effect driveability, throttle response, and noise. As for power, look elsewhere. It's simply not a cost effective performance part.

 

^ link to said dynos?

great news! martyg35 just stepped up and volunteered his sexy FuRookie SRI for dyno

link to thread

 

You have to get very creative with your searches on this site and my350z. Some of the plots may be gone by now because some of this stuff went back to 2005. IMO, it's not worth the time. There are too many variables and there's no way you could do it all in one day. You're talking about dynoing 8+ intakes. Hourly dyno rental fees are around $100/hr. You'll need it for at least 12 hours of dyno rental and will need to do at least 3 runs on each intake. That's going to be absolute hell on your car. You're talking thousands of dollars in fees and intakes to get answers most of us already know. That is aftermarket intakes are essentially noise makers on these cars. Not one of those intakes is going to make any sort of significant gain that will effect 1/4 mile ET/MPH.

 

I'd be more interested in a pressure drop test for various oem offered panel filters. Especiall new vs dirty.

 

^ any idea on how to measure that?

 

Cool idea rob- I'm all about numbers and organization so I applaud your idea and setup for going about it.

However, I must agree that there are really going to be a ton of variables to gather all the data combinations.

I disagree that it will take all day or that it will be hell on your car though.

My only suggestion is to switch to ART pipes before the tests?

 

you provide the pipes and I'll use them

 

got a promising email from weapon r, a R&D guy asking me details about the dyno session.

additionally I found some local guys with parts who were willing to help.

platelock has a Takeda intake I can use, and w0rthy has the kinetix velocity manifold.
