Stillen vs. Smoky: your take on intakes

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!

So did you run 30 miles with the Top Secret intake or did you just swap it out after you dynoed stillens?

We did two dynos on the Top Secret -- an extra one to confirm our initial findings.

Drove about an hour (mix of freeway and stop-and-go) on the Top Secret before the final dyno. It confirmed the first pull, in which we simply installed it immediately after the Stillen dyno.

Wow, good luck to anyone that wants to compete against Stillen's G3 gains....no one will believe you if you do!

It doesn't have to do with being Stillen -- people would be doing the same thing if it was Injen. It has more to do with it not being a CAI.

From a fluid dynamics standpoint, air/liquid passing through two tubes of equal diameter will experience less resistance in the shorter pipe (i.e. less of a pressure drop=more flow). The advantage of a CAI is pretty much limited to the cold air aspect alone.

As someone had alluded to, it is possible that the dyno setup may have provided sufficient airflow to keep warm air from entering the SRI (or perhaps the water temp was low enough that the thermostat was closed and the radiator didn't really heat the air).

Basically, an SRI can make more power, provided it is somehow shielded from incoming hot air. That said, I do not really see anything special about this design that makes it unique in this regard.

Yes, pretty much this.

Either it increases airflow greatly or reduces the temperature of the air into the engine which, as a side effect, increases air being received by it.

Exactly, it has nothing to do with brand, it has EVERYTHING to do with it being a CAI against a hot air sucker AKA SR intake.

Hell, I'll ask the man myself.

We will be interviewing Smoky next week (through a translator).
With that being said, are there any particular questions you want asked?
-keep it professional

I will do my best to ask him about his thoughts on other aspects of the Z as well, just let me know what you guys have!

Someone needs to show some pics of this intake, inside and out, so we can answer some of the questions Phelan and others have posed.

Assuming this intake DOES NOT lean the car out, then it's got to have some sort of unique design element that is allowing it to draw in a lot more air into the engine. Maybe some sort of special velocity stack or vanes on the inside of the piping...I'm really not sure.

I do commend them for doing a closed-hood dyno though, I haven't seen anyone do that with a short ram yet.

Zsteve · 03-28-2010, 12:54 AM

Me personally I dont think anyone is going to come up with a super CAI that out performs all others by marginal amounts. As long as the CAI is pulling air from the outside of the engine bay, they are gong to be very close. I mean lets face it, its just some tubes, a filter and a MAF. Small changes in any of these may produce gains but Im sure all companies have done every variation possible to get the most out of a CAI. So if one does better than another by a few hp, can we really say its better when one can not, and I repeat, can not excatly duplicate the conditions every time? I say choose the one that looks good to you and that you can aford.

whats the release date on top secret intakes? pricing?

Well put, I agree.

Not that it prolly matters, but did they shoot any video?

LOL it's maaagic

My take: My knowledge of Smokey (Smoky?) is very limited, but I know one thing...he took his name as homage to Smokey Yunick, the legendary NASCAR engine builder. This new Smokey had better be as good as his name suggests.

This thread should become epic. In for updates.

From what I have read about the Gen3, the length and bend of the tubes promotes smoother airflow at the MAF, negating your comment about resistance in the shorter pipe.

If this is true, ask him to reveal his secret intake design. Good luck!
