I like that idea...haha...But really, do you guys think the Cobb airbox will give any extra HP?? I think once the air goes into the turbo will get hot anyway, that's what the intercooler is for right? (boom01)
Wrong. Intercooler is no substitute for a poorly designed airbox and filter. On the intake, the issue is more one of cubic feet per minute flow rate, and somewhat less one of temperature. The stock intake is very restrictive and does not permit a flow rate anywhere close to the ability of the MAF and ECU to tune for intake charge and add fuel for the extra air that can enter the engine through a properly designed intake.
That's why good cold air intakes or short ram intakes can show 20 whp gains over the stock air box.
The intercooler is designed to reduce the temperature of the compressed air after it leaves the compressor side of the turbo. The warmer the air that enters the compressor, the hotter it will be when it comes out. So, that's why, at least in theory, a ture cold air intake can produce a bit more power over the short ram design under some conditions.
So, for the Cobb box to get the attention of those looking for serious power gains, it will have to be able to flow like a good CAI or SRI. There still appears to be little to no data about how air enters the box, and what the CFM maximum will be for the air entering the box. If there is, perhaps someone can post it.
