See thats one thing i was wondering about as well in my GTI. I still have the stock piping coming from my bumper inlet directly to my engine. Instead of dumping the air off in the airbox, its now dumping it on my Cone. I was thinking, well damn, at speed how could it possibly be sucking hotter air? Isnt there circulation, especially if im shooting air directly at that area? I figured similar for a 944, or at least a 944 with a duct built into the headlight. I may not be seeing big gains, but then again im not really after that. (the turbo sound with the cone is much better than with stock airbox though! how could anyone resist!)

Well, I way over-generalized there, I meant the ricers that throw on a "CAI" cone filter, which happens to be located right next to the engine, sometimes the exhaust manifold.
But I do have a question. If adding something so simple such as a CAI, tuned properly, can net at least 10HP on some cars, why don't they just do this at the factory? I can't see anything detrimental from this, you're simply tuning what's there to make it more efficient.

ok I recall writing about this same topic back when I had the EuroSpec944 SN. Try searching. I even supplied Dyno information with the cone filter project.

what if you did something like this?
the green is MAF
The red is custom pipe
the blue is K&N cone filter
and you cut holes in the nosepanel.
looks good and your getting cold air on an N/A
right?

Thats basically how an S2 works isnt it?? Instead of air coming right from a hole in the nose panel, it comes from the top radiator inlet and up through a hole in that floor? I think thats how it works.

The na gets outside air anyway. It just gets it from the wheel well.
I heard that the wheel well is a high pressure area anyway. Is that true?

campeck, i did something similar to that on my old 944. take a look at P-car, and believe me, it still doesn't work, you lose a lot of torque with that setup.

yeah but yours is in the corner.
not in under the panel.
and while you drive
air would get all bunched up in there and make a little bit of pressure.

Under the front panel isn't going to accomplish much. You'll get little resonance tuning, the air won't be much cooler, and it won't be particularly high pressure.

the neck leading to the air flow meter can't be long since again you'll be looking at a loss for power, Perhaps custom making an intake boot that is hard piped into the nose panel with a cone there may provide better ventilation and cooler air. The question is, is anyone willing to spend $$$ for 3 more HP maximum?
Anyone? Bueller????

You're dead wrong.
The length of pipe is tunable and if you get it right, you flow more air through it, especially at certain rpms. What will make more power is a longer pipe that is tuned for the rpm where you want to be making power.
As Danno said, the AFM is certainly the restriction. The AFM blows goats. A MAF would rock. Unfortunately for me, the rules prevent me from changing the air metering device. But, as I said before, IMHO the adapter to the AFM is going to be critical to create better flow. Most of the adapters blow goats too.

The biggest reason nobody can make any power with a NA 944 is because everybody believe they can't. They live a self fulfilling prophecy.

wow george, getting all psychological on us.
but anyway...
the reason tehy didnt do it on anything but the s2, so they could make more models of the same car with differences liek that , that poeple would go for.![Big Grin](https://rennlist.com/forums/images/smilies/biggrin.gif)
