Harmony has been nice enough to try and explain this to me, but I'm just not getting it. Here is their description: "The ram air system removes any weak flow points in the factory system. It includes a carbon fiber intake cone, Naca intake duct, BMC Air filters, all hardware. This will remove your Pre air box filter system increasing air flow to. It actually runs behind the driver side drip panel, you cannot see it in the engine bay. The carbon/kevlar photo attached shows the intake cone in the exterior drivers quarter pane." So does it remove the Airboxes in the engine compartment? Or do our Ferraris already suck air for the engine through the inlet hole next to the doors? In that case, how are these aftermarket systems improving upon that design? They remove the "prefilter," but I have no idea where that is. Thanks. Mike.
And here again yet another compelling reason not to smoke crack...... Sorry Mike, can't help ya....just felt like throwing that out for laughs. IMHO, doing the BMC's is a no-brainer, but that whole cold-air intake system is a LOT of money spent for just marginal gains. Damian told me that for every 10-degrees cooler you make the air, you pick up another 1 horsepower...or something like that....so what are we talkikng about here, another 5 hp? And what does that system run?? Do the filters and get a louder stereo
It basically removes all of the various boxes and hoses from the point behind the air intake hole (behind the driver's door) all the way to the airboxes in the engine compartment. It's supposed to be a cleaner line (more direct with less angles, etc) from the outside air to your airboxes in the engine compartment.
GruppeM Japan claim an additional 8.6ps with a full system. Air filters are a LOT bigger. Surely they must hit the limit of the MAF sensor with this much additional air being breathed in??? ; RAM AIR SYSTEM Original Filter MAX Power 384.6 ps 376.0 ps MAX Torque 39.2 kg/m 37.9 kg/m Link to follow ; https://www.gruppem.co.jp/onlinestore_en/index.php?main_page=product_info&cPath=1_16&products_id=18 Image Unavailable, Please Login Image Unavailable, Please Login
This system does in theory work by reducing the obstructions to the air flow. However, the relevant cost to do this makes little credible sense for eveyday driving. Replace the air filters with BMC and you'll be ahead of the game.
So where do I get a set of BMCs from? or what is the part number of the filter? I might be able to find one at a BMC dealer in huntington beach. How about the Carbon Airboxes? Much increase in performance? Engine harmonics?
BMC P/N for the 360/430 is FB208/03. There are two required. Not easy to find. You might try FabSpeed. Mixed results with carbon air boxes although they in theory should yield an improvement. Have to let those who have them discuss this issue.
I feel there are 2 items claimed for increasing Hp: air flow restriction into the intake and ambient forced induction. The first is discussed - removing all the kinks, curves and restrictions to air flow to the intake manifold. In theory, more air moving faster can translate to cooler air charge and greater fuel input, hence Hp. - to a point. You can only make it so efficient. Second is the high speed potential of forcing air into the air box which acts like a free supercharger. You get a few extra ponies this way but only when moving quick enough for the intake stream to compress the air. In simple terms, imagine a type of funnel that forces a wide air stream into a narrow jet. The output airstream is denser than the intake, "charging" the fuel system. This is old school hot rodding. Like everyone else says, don't expect big Hp increases.
