Original thread on G35 driver *click 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 motordyne 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 with large velocity ring (T3K_V35)
- Stillen Intake (gmotion04)
- FuRookie SRI (martyg35) thread
- Tekada (platelock)
- Kintetix velocity plenum (w0rthy)
- AFE (not sure exactly what they are sending me)
- Weapon-R (not sure exactly what they are sending me)

I might get:
- Top Speed intake (waijai)
- 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, possible
K&N - http://www.knfilters.com/ - no response
HKS - http://www.hksusa.com/ - no response
Weapon-R - http://weapon-r.com - repsponded, possible
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 think the ECU reset between runs will just let you know what intake makes best power in the learning phase. Next i think you should drive around all the intakes and datalog, so when on the dyno you can get them to the typical real world inlet temps.

JWT run about 7 to 8 degrees over ambient temp, and i have never logged with other intakes.

 

yeah I'm not sure how to handle that problem. realistically I cant go drive around, let it learn, and dyno every intake again. the weather would change, and probably affect the dyno number more than the learning process. Not to mention the changes from restrapping on to the dyno.

 

Good idea, but your wasting time doing those NA mods when a well driven 6MT would beat your mod'd auto.

Back in the day I gained 10whp from switching from an AEM CAI to a Pop charger, all other mods/tune/conditions the same.

The tuner described it as "what would you drink something faster with, a loooong straw like the AEM or a short staright straw?"

 

well so far I've not lost to a 6MT, lets not turn this in to a 5AT vs 6MT argument please.

infact, at a recent dyno day (early this year) I made the same if not more power than any 6MT there.

again, thats not what this is about. this is intake vs intake on a full bolt on car. I'll be putting my cams in at the end of oct, beginning of nov. and I want to know which intake will feed them the best.

 

dyno'ing an intake without tuning = absolutely useless. The intake affects the tune (some more than others).

trying to do this on a static dyno, with an open hood and no real airflow and no datalogging equipment also = useless

while a noble effort proposed, save your money and put it towards your build

not sure why you're doing an MRev2, considering an 05 G35 auto (non revup) already comes essentially with that piece as standard

The function of your cams is going to be affected by far more than just the intake, which is only a small part of the equation. Which ever feeds the engine the most consistent cold air is going to net the most consistent power. The rest is all the interaction of the cams with your manifolds (in/ex), and tune

 

the motordyne mrev 2 is advertised to make HP on our cars, I did something similar in my port and polish project and I wanted to see how it compared.

 

as stated in last few post i agree with. Also as i posted in ur regional thread i think you should have test pipes not hfcs to do all this testing.

 

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.

 

awesome news, AFE and Weapon-R have agreed to ship me an intake for testing today!


not sure which one they will be sending. weapon-r had some additional terms which I have no problem with accommodating for the testing.

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

 

Pointless or not, this outta still be pretty interesting to see what happens.

 

Well, I'm glad someone is at least attempting to do this. It's about time.

Oh, and I totally saw your car at the Dallas Cars & Coffee meet on the 2nd. Very nice ride.

 

ah thanks! appreciate it... sorry we didn't get to meet.

 

i wouldnt reset the ECU unless ur gonna drive 50 miles for to re learn.

 

I am fitting a larger v-stack in my 06 airbox. I should be able to get a baseline with the larger stack before I install my new headers, but that is a few weeks from now.

 

after reading like all 9 pages on g35 driver with everything your changing and what your NOT changing is gonna b pointless. You state you dont want to do 100% stock bc it will b worthless. You state you wanna have no bottle neck or w.e. So 1 why use HFCs? How is that free flowing? Why are you going to be changing your plenum out? If you really want "free" flowing exhaust get 2.5"tps to 2.5" TD exhaust. Or 2.5" tps-2.5inlet y pipe 3"outlet- 3" exhaust. OR STOCK EVERYTHING 3 pulls then start changing out intake pieces.

Theres so many variables into making the "perfect breathing engine" its stupid. sorry fo rlong post posting from my droid X at the bar. Me and a few other z owners are all discussing this thread

 

I emailed motordyne to see if there was something we could work out for testing with the pipes but received no reply.

however, I was able to find someone local (TrixR4kidz) who was willing to let me use the ART pipes for my testing.

so to confirm, this test will be done with ART pipes installed.

Also called the dyno shop today and confirmed everything. This will probably be done on the 23rd of October at 2 or 3 pm

 

I bought my Z three weeks ago so i am a noob, but what are your thoughts on a JWT Popcharger and Kinetix Racing SSV Intake Plenum for starters for my intake. Is the plenum worth the $$?

 

You Sir need to use the search button!!

 

oh ohhhhh....
