Stillen vs. Smoky: your take on intakes

370Zsteve

One of the design advantages of the Stillen setup is supposedly the way it smooths out the airflow. Short intakes, again from what I've read, have too much turbulence around the MAF since the intake opening is much closer to the MAF. Again, this is what I've read put the flame gun away.

I own one and im not afraid to use it!

Y'all are welcome to come to Import Reactor and ask Smoky himself why is he so godly during his 1hr panel. rofl

Wait until he tunes that cars next week

Forrest

cant wait to see some one on the forums bite the bullet and dyno this intake and see what happens.

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.

nuTinmuch

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.

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.

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.

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.

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.

370Zsteve

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

Thanks again to the OP for doing the test.

I just wanted to throw out some points since I used to work around this stuff. I bounced this test off a few friends and these are some thoughts I wanted to share.

First: In terms of air temp, why do some seem to forget we have ducting through the core support to direct cooler air toward the filters (in terms of a short ram). People seem to forget that when they get going about how a CAI takes in cooler air, it may not be as big a difference on this car versus most others that don't have these ducts.

Second: It's unfortunate that they were not plotting Air Fuel Ratios on the dyno. After seeing this and talking to some people I think the air temp is less relevant versus what the design of the intake does to the AFR. Lean means more power. If you design your intake to push the AFR as lean as you can go and still be safe, your intake will make better peak numbers on the dyno. Pipe diameters, pipe length, filter restrictiveness, AFM placement all have an effect.

I think the intake that favorably suited this cars fueling requirement for the mods that it had won the shoot out.
