Intake Comparison

[MikeJr74]

Not necessarily. Most people who have dynos don't even sell Stinger parts. It would be really easy for someone to test out if they're already visiting a dyno, for sure.

The filter isn't going to do anything to add cool air to the system. It sits in the same box as the stock filter. Flow may be slightly increased but temps will remain unchanged.

When I had them installed I felt no difference from stock.

Just curious, how does putting a new intake with the filters sitting in the engine comparment make the air cooler than that which is running through the stock filter box and snorkel? I thought the power was increased more by air flow versus temperature?

I don't think any after market intakes are colder than stock they just flow better. Exception - New SSR intake should be colder.
K&N panel should flow better but stock snorkle may stop it.

Me personally I don’t put to much faith into all the gains made with intakes. When people put a intake on there car and they say they can feel more power and then you see a dyno chart and they make almost no more power. I’ve done the same thing over the years modding a car “feel the power” then put on dyno and see you lost power. I think a full intake is more just sound then anything. I would love to see a stinger on the dyno testing all of the intakes vs stock intake and k&n panel filters. Over the years I’ve seen other tests like this been done and the gains can be 1-3hp if not no different. The stock intake on the stinger is very well designed. The test I saw was from a 370Z I believe and the intakes they tested made no difference in gains and even lost power. Also saw it with a bmw can’t remember what model.

My results on just the intakes on a stock car were favorable according to Dragy.
Stock - 13.67 @ 103.8
W/ Stillen Intakes - 13.24 @ 106.6
Same stretch of road 2 days apart. Second day was 10* cooler though.

According to this HP calculator when you put the MPH & in 4023# for the car it was a 28.8 HP increase

It's not a dyno chart but in a way Dragy results are a better judge of true performance.

I can say I felt no difference between stock and Stillen. But I think the hp increases in many of these intakes happens in a RPM range that folks don't spend a lot of time in. So in a race the extra power might be beneficial but it may not be noticeable on the street.

I think we are missing an intake system..... What about the weapon R intake from import mike? Anyone have info on that?

I going to sound stupid so get ready..... Im thinking there is room to weild another intake pipe off of it giving it more air to suck in... Has anything so weird ever been done like that?

The compressor housings on the turbos is going to limit the amount of air your engine will take in. If the intakes are properly sized, adding another one wouldn't do anything.

For those with K&N Typhoon intakes, wasn't there some fitment issues that you have either replace to make it fit better? I can't remember what was the resolution to make the K&N fit better.

From what I heard it was the AC condenser lines that interfered.

 

[Manaz]

Here is the information that I have gleaned from the forum. Any additional information would be great.

I'm not sure how to really add air temperature. Are there enough people that actually know?

Edit: I added Jonny Tig.

The Jonny Tig intakes are definitely a "Yes" for "Cold Air".

 

[Christopher Léger]

Idk what ppl are complaining about k&n typhoon but mine had no issues

I thought the power was increased more by air flow versus temperature?

Engines produce power by burning fuel and oxygen. It's generally oxygen that's the limiting factor - there's no point injecting more fuel if you don't have enough oxygen to burn it (you'll run rich, have incomplete combustion, and actually lose power). Not enough fuel is WAY worse - running lean breaks engines - this is (one reason) why, in general, factory tuned cars don't run 100% duty cycle on their injectors (they're sized with some headroom).

Easier flow (less restriction) only helps if the airflow was the restricting factor to start with.

Once you don't have flow restriction (the car can ingest as much air as it wants, as quickly as it needs), then temperature becomes a factor - cold air is denser (and thus contains more oxygen molecules for a given volume of air), and colder air helps keep combustion temperatures down as well, meaning you can run more advanced timing (this is how water/meth injection works - it cools down the intake charge, as well as increasing the effective octane of the fuel/air mix, allowing even more timing advance). Cooler air and higher octane allows better controlled combustion, which allows for timing advance, which allows for more efficient burning of fuel, ultimately all meaning more power.

Back to my original point - if you're effectively not flow restricted, for a given octane level of fuel, the only way to improve power is to allow the engine to burn more fuel and/or to burn fuel more efficiently - and the only way to do that is with lower air temps in your engine. You can work to cool air down after ingesting it (this is what intercoolers do, same with WMI as I mentioned earlier), but like your health, prevention is better than cure, and if you can start with a lower air temp at your air filters, you're going to (all other things being equal) end up with cooler air in your intake manifold after your turbos and intercooler and WMI and whatever else you try.

So if I have already WMI then I just have to care about the air flow restriction and not care about weither the sucked air is warm or cold? That would mean that with WMI an intake with no heatshield and a huge ass filter is the way to go.

Am I right?

 

[Manaz]

No. The cooler the air you suck in, the better off you'll be.

 

[xot1]

No. The cooler the air you suck in, the better off you'll be.

But how much of a performance gain will you see by getting colder air when your IATs are already low?

 

[Manaz]

Lower is still better.

 

[Angeski]

How does injen double its hp to K&N intake? One if them have to be wrong.

 

[xot1]

Lower is still better.

Nobody ever said that higher was better...
I was just saying that the temperature of the air outside of the intake may be much less of a concern with WMI because lowering it will not have a dramatical impact on IATs. However air flow restrictions will remain a limiting factor. Thus with WMI a good air flow seems to be a higher priority than a good heat shield. (in many designs there is a bit of a tradeoff between the two).

I believe that both are publishing actual results, but as there are no regulated standards for testing they could have been on different makes/types of dynos, using different testing methods, different environmental conditions, different cooling aids, etc.

Ooooo. Ok. I didn't consider this. We should get people with these intakes posting their results so its more specific.
