Stillen vs. Smoky: your take on intakes

Nobody is going to run with bumper off and hood up so I personally only care about results with bumper on hood down.

Oh comn guys... YOu really wanna do stillen g3 vs TS intakes??

I can know the results from now... stillen will go over the TS easly...

lets see.... Long tube intakes.. vs Short ram intakes..
Stillen's long tube intakes give more power than Injen's long tube intakes..

so even if its long tube intakes vs long tube intakes.. stillen still the winner.. And now your comparing it with short ram intakes??

Im not saying that the TS sucks.. they are droll!! but you cant compare it with stillen g3

and in fact.. even if the TS gains more.. im sure that after 2-3 runs it will go very low bcuz it will suck hot air from the engine

ok well the top secrets if they are anything like the g37s intakes will be rebadged HKS units with a different color foam so thats a loss in power right there on a hot hood closed run, and then gen 3's have shown over 10hp gains those conditions so my moneys on stilen in fact all 500 bucks of it that i spent on the stillen for obvious reasons. the only intake comparison that is really interesting is injen v. stillen.

All that aside it's good that you are doing a 370 build and great that you are going through the lengths of doing a comparison just be truth full run it hood closed with sae correction to get the closest real world numbers you can instead of trying to hawk the top secret name that they are so fond of.

Yeah i know i'm a topsecret hater, and i understand it's a good move on the part of your dealership to use the name as there are a bunch of uneducated racerboys that will eat that $hit like it's candy and shell out big time for the parts, but seriously everything they make costs twice as much as parts made by other companies and isn't worth a even a fourth of the 1100 bucks this intake will cost if priced similarly to it's g37 cousin.

the reason i asked is because the only dyno comparison from complete stock to stock w/ G3 I know is done by RCZ... and when he did that he had his bumper off, and i agree with your statement above...However, this is also the dyno numbers that most people are basing their assumption that the G3 has the most power gains over stock...

with that being said, i am pretty sure most people will just discredit this dyno study if it doesn't show favorable to the G3s... like what happened to Technosquare's dyno study of stillen bolt ons... and its actually happening already (see the posts after yours)... any case, im pretty sure these guys will be smart and independent enough and will keep scenarios in a constant environment.... so i am definitely in for the results

Just as you would from the stock to the Gen 3's..
I saw the same thing on the dyno going from the NISMO exhaust to the HKS exhaust.

Well put but it will still be interesting to see, especially if the results are not close like most people say they should be. I think the best way would be to allow for adaption, hood on, bumper down, same fan in front (replicating driving conditions).

However it turns out, thanks again for doing the test!! +rep.

Of course it would be, but when selling anything it's pretty normal to create the conditions that best support the product you are selling. In other words, you never really know if the numbers are real or not unless there is full (and honest) disclosure. This is an area much of the aftermarket seems remiss in (not aimed at Stillen BTW)

Testing will be done soon. We have the last run going now with the TS intake, so we will post all the results shortly. Since we are talking about disclosure, I can let you all know that we are actually putting the Stillen Intake on a different 370Z that we are tuning, so all we hope for is a good test, and that both perform well since we will be installing both. Once everything wraps up, we'll let everyone know how it goes!

Awesome, and +1 rep

Question, will the testing area maintain the same temp and humidity during both tests? I note the testing was due to start at 9am.

The results are in!

Mothra is heavily modded at this point, an indication that Jason has been working overtime. Wheels are on, but rear brakes are off, due to a fitment issue that arose late yesterday. New wheels in the same style will address this. The suspension pieces from Top Secret are also on with about a 2” drop all around. The catback is also now on, which drew attention up and down the block. We’re in good shape to have her ready for Import Reactor and a tune by Smoky Nagata.

But enough about that. What you asked for is the straight story on intakes, and we are here to deliver:

Stillen G3 CAI: 281hp, 217tq
Top Secret CAI: 286hp, 224tq


We started our testing around 10:00 this morning, Humidity was measured at 58% with an outside temperature of 56 deg on site. By the time it was finished, conditions had changed to 48% humidity with a temp of 66 deg. The shop is mostly enclosed except for the garage 2 garage doors to let the cars in and out, but it is not 100% climate controlled, so everyone will need to keep that in mind. This timing and temperature actually seems to favor the Stillen pulls, if the differences affect this test at all.

The car was driven approximately 25 minutes on two separate trips between the tests (equal to the time it was initially driven to Secret Services). So, the ECU should have adjusted and the warm-up should be very similar.

So, what do you think? We were honestly surprised! Our Stillen G3 will go into another 370Z we’re having tuned by Smoky. We’ll keep the Top Secret one in Mothra.

no chance. A short ram w/o heat shields will only lose power.

great publicity though!

See the dyno PDF attached. That's the closed-hood run for each setup.

It honestly surprised us too. One thing it proved is the Stillen is an excellent value, producing similar gains for a whole lot less money. That's why we're keeping it for the second Z!

Smoky says his intake and exhaust are optimized for the tune he's going to give us. We're excited to see! Stay tuned!
