I think that the Stillen intakes are a great buy not only for some high rpm breathing, but it changes the character of the car completely above 6k rpm. It makes the car feel much more aggressive and eager both in the throttle response/power/sound which I think suites the character of the car. Match the Stillen intakes with fang vents to force air up to the filters and you have a great intake setup.

My G 3's made 20 rwhp over the stock intake, It was the first mod that i did
Base line 264. stillen G3 284. I have the dyno to prove it with the bumper on.
It's a 7 AT.

You may not make 18whp as they claim, but theres a definite power increase along with a much nicer growl. Nissan designed a great intake system, but to pretend that it was designed to make the most power without regards to cost is naive. You bought a $30k sports car, not a ferrari.

furthermore TONGMAN Idk why getting 15-20whp from this performance part would be hard to accept for a N/A motor when some members showed/proved that they Made these gains while running independent dynos...

BOLIO 671 · 09-24-2010, 07:05 PM

Z eliminator....with. ur ET and trap speed I believe that this part produced some significant gains for you...Thanks for sharing

FastJew · 09-24-2010, 07:36 PM

Installed the G3 this week and there is a definate increase in performance/sound. Can't really understand why this is even being questioned with so many satisfied customers out there.

Look forward to going to the track this weekend to verify the improvement.

So far best time is 8.71 in the 1/8th @ 83.8. Surely these will get me to an 8.6? Hoping for 8.5's.

Not to bash, but just to further a conversation about this. I did not say that I do not believe the power gains, I just said that it was hard for me to accept. I've personally seen dynos in the past for naturally aspirated vehicles and the most I've ever seen in person is about 8whp on a cold day. On turbo applications, I would definitely believe that a single CAI mod will produce gains of 20+whp. No doubt that one would feel a difference before and after a CAI. I'll check out the dyno forum for CAI gains.

So I found this about the Injen CAIs.

So you gain the peak hp from 7k rpm to 7.5k rpm only.

I found RCZ's thread when he reviewed the Stillen G3 intakes. He dynoed 20whp from the intakes, but seeing that his bumper cover was off and air was directed directly to the filters, it would resulted in the high hp gains.

STILLEN Longtube G3 Intakes. Review, Dyno and Impressions.

But RCZ did state that " I was pretty much speechless. I have never seen a 20HP gain from intakes on an N/A car. "

Tongman....I do appreiate the info that you are bringing to the table...after all we are all here to learn from eah other based on our info and individual experiences.... I too was at one point lead to believe that intakes do not produce significant gains....however based on all that I have read regarding the Stillen G3's I am pretty confident with the numbers that they produce and strongly feel that they are a great performance part.... don't get me wrong...not all intakes produce good results for the Z...for instance the Takeda short intakes as well as other intakes seem to produce little to negative power for the Z....however when talking about the STILLEN G3'S I feel its safe to say that based on what has been said about this part as well as RCZ'S and Semtex's reviews/dynos...its pretty clear cut that these particular intakes produce good results....

You're right about RCZ produing 20whp with his bumper off....but in Semtex's thread he did his dyno with the bumper on and produced 14.7WHP... Also in Semtex and RCZ's threads it was debated about the whole bumper on/off deal and some people posed some good things to consider...such as when you're on a dyno that you are at a stand still...so taking the bumper off and having the fans blow could probably fabricate a real actual driving experience where your car is traveling on the road having wind/air being forced into the grill area...some also pointed out and argued that the amount of wind/air that the fans are blowing into the filters with no bumper on can not duplicate real actual wind/air as compared to when driving on the road and not at a standstill such as a dyno run...of course this is subject to debate and interpretation....but they are both good points to consider...I have found supporting info to prove that other intakes don't produce good numbers...but it seems that Stillen got this product down to produce decent gains....I mean RCZ, Semtex, and ZEliminator got great results and all of them did independent tests/dynos to see whether Stillens claims of Whp gains were in fact true.... I have not found one thread yet that negates with actual proof anything bad about the STILLEN G3'S...

The reason why I started this thread was because as I was conducting research on this particular part I came across a post made by NYBLADEZ on a Stillen G3 thread that was posted by Elia CID..in. which I quoted NYBLADEZ's comment on the opening post of this thread on Page 1....I couldn't figure why he and others felt this way about the Stillen G3's when all the research I did on this forum said and proved otherwise...

Hey ZEliminator...out of curiousity...when you dynoed the 20rwhp with these intakes was your bumper on or off...and were fans used to blow directly into or towards the intakes?

smokejr · 09-25-2010, 09:05 AM

Things I noticed after installing a G3 intake were smoother/easier throttle
response when going very slow, smoother coming off high revs, the car just
doesn't fall off the revs, and when hitting the gas revs up smoother not like
it is being thrown to high revs. I only have an intake so far, but these are the
same things I noticed on last two vehicles I owned and changed intake and
exhaust on also.
The one thing I didn't like was having to cut on the car, if you wanted to
re-install the stock intake again for possible trade-in then you might be
looking to replace the piece you cut on possibly??

I'm not a Stillen hater, nor do I want to derail the thread, but you can get those benefits from a more breathable drop in filter panel in the stock air box.

Z eliminator · 09-25-2010, 05:35 PM

My bumper was on.
With full bolt on's i ran 12.8009.
I have now increased the trap speed's to almost 113 mph, (112.9 is my best)
With the stillen CBE, Berk cats, stillen headers, Under drive pulley NRT. i went from 264 rwhp to 311 sae or 322 actual rwhp. ( and my own cobb fuel curve) The power drops off at 7400 to 7500 rpm. It still make 298 at 8100 rpm.
47.6 rwhp was the actual gain and its a 7 AT. SAE RWHP.
Jnauts car is going at 12.68 and it's a MT.
these 2 370' Z are not slow and i can tell you that mines faster on the street than at the track.

No question about it. Never, I repeat, NEVER believe a vendor's claim of added HP. Subtract about 50% for a more realistic gain.

I gained 16HP from my Berk CBE as first mod.

When running on the dyno, the Stillen intake produced on the average 3 more whp but less torque at 270 whp and 216 lb/ft with the power gains coming high in the powerband above 6700 rpm. Below 6700 rpm, the Stillen Intake lost a slight bit of power and torque. This isn’t the whole story though. For the sake of curiosity, we removed the front bumper fascia and ran the car with the airflow of the dyno’s cooling fan blowing straight on the filters. We were amazed to see that the Stillen intake belt out an additional 10 whp nearly completely across the board! Not believing our eyes, we ran the car with the bumper cover off for many pulls and the numbers repeated. We then replaced the bumper cover and the power numbers dropped to what they had been.

Stillen’s cold air intake is clearly a superior design with great power potential but the bumper traps hot air in the vicinity of the filters which nullifies most of the gains. We hope Stillen reads this and creates a bumper vent and heatshield kit so that the full potential of this great intake can be realized. Since people do not drive without a front bumper we are only going to show our with bumper cover power results."

IMHO, the metal of the CAI gets extremely hot in a closed engine bay. Removing the front fascia allows much more air into the engine bay, possibly cooling the pipes to release more HP. Another angle to consider.
