~Any change other than the intake could change the results, but no way to truly know. It is technically an equal comparison since both ran with the same performance mods.

~The only "true" test on a dyno is hood closed, bumper on. Some will say for SRI setups a hood open run will represent a "more realistic" result, but with the hood open you are pumping in more air with that hood open where it would never get that air in the real world.

Thanks... So this dyno test pretty much tells the true story....

How much is the TS CAI and Titanium exhaust again?

Well, Top Secret gear is not only difficult to get, it's expensive. However, time after time, they prove that you get what you pay for.

The good news is: Ken at www.swatperformance.net (forum sponsor) can not only obtain these items, he can get you a good price!

He's a great guy and a Nissan guy through and through.

hmm, I'm not doubting the results, just the validity of the test. I think you maybe have momentarily leaned out the car when you put the short rams on.... might wanna retest next time when the ECU has had more time to adapt to the short rams. I love top secret, but it doesn't make a difference who makes the short rams. We have seen it time and time again that the long tubes make more power. All I'm saying is that if you gave me both for free, I would have the Stillen on the car...

I mean no offense, nor am I trying to start beef. Just my 2 cents.

Heres the deal, none of us here were there, basically meaning that we all have to assume that this test is true, and the results really occurred. However, not being there and seeing independent results with SR intakes time and time again, hood open or not, they either see ZERO gains or lose power throughout the power band. People, it makes sense, look at where the G3's are located, away from the hot engine bay, directly in front of the one piece that keeps the engine cool, the radiator, i/e best possible location for cold air to come through. A filter sitting in costant heat with temps easily over 200, vs. a system that pulls in air only 8-15 degrees above ambient, im sorry but regardless of any opinions i hear about SRI's, science and proven tests show that NO SR will make good power on this car.

and btw, im not only saying this because I have the G3's, im sure Injen owners will agree with me as well, they are true cold air intakes. The HKS/Takeda/JWT/ and this one will in no way produce better numbers than a true CAI.

I agree. Maybe it's a design secret and we'll never know, but i'd love to understand the difference between the previous incarnations of the short tube, like takeda's or something. Top secret is great, but i continue to wonder how they've succeeded where previous have failed.

exactly.

And i'm not trying to hate. The engineer in me is just very, very curious. Without being there i can't help but question!

The tests that were posted were done with the hood down and bumper on, so they were as "Real World" as we could get. As far as the validity goes, we had the Stillen Intake installed, and it was driven roughly 30 miles and WOT multiple times before the Dyno. It was then switched to the TS, and the same was done. Its a fine line between letting the ECU adjust and not taking too much time in between tests. In the end, no test is perfect, but this is as close as anyone can get.

As far as the mod's are concerned, (and yes we are aware that some of these do not add power, but still should be disclosed) so far they are:

Either TS or Stillen Intake
Stillen HFC
Stillen Headers
Top Secret Exhaust
AP Racing Big Brake Kit
B&M Short Shifter
ACT Clutch Assembly
NST Pulley Kit
I-Forged 20" Spring Rims
and a few others that don't affect a dyno run.

In the end, we are all still surprised at the results. We welcome any other questions that you guys might have. Bottom line, for the current set up that we have, the TS intake reaps greater benefits than the Stillen. Both excellent products either way. Maybe we will redo these tests with more mod's on next week and a few forum members can come watch??? Up to you guys!

Thx. The only thing I am thinking is that the TS intake had an advantage with the TS exhaust. You said Smokey stated the TS Intake and Exhaust were tuned to work together.

Would that have any bearing on why the TS intake came out on top?

What were the baseline numbers? Did I miss that?

:tup:

i kind of predicted peoples reaction to this one :tiphat:. i think phelan got it right though, i think somehow theres a design quirk that sets TS apart. perhaps just like the AEM technology or the inner cylinder/tube by the MAF in the injen intakes. although, i would like to see videos of the dynos and hear how that set up sounds?

I agree. I will not be convinced until I see another dyno run with AFR results.
