custom intakes

[ncorrell]

im wanting to remove my airbox in my 330 but i dont want to buy one of those 300 dollar air intake kits. way over priced. so i thought id just get a cone filter and make my own heat shield. im wanting to kno if others have done this and whats the best way to make a custom heat shield. thanks.

Very very very easy to do, and yes it will work. You need the metal for the heatsheild, some tubing you can get at Lowes or Home depot, and the filter, hell you can get that off Ebay.

Hopefully you also have some pretty sophisticated computer modeling software for the airflow as well, or you're very likely to cobble together something that's far LESS efficient than stock.

yeah this, your best bet is to go to a performance shop and have them custom fabricate you an intake

Fog your current intake. Just add another hose to the intake that rams air into it.

Yeah, because every performance shop I have ever worked with has engineers and CFD seats. :rolleyes

If you want to make your own intake, go for it. It is pretty unlikely what you make will make less power than the stock intake, which is designed to be quiet, not to be efficient.

cosmoracing.com has a short ram intake for $60, make your own heatshield and it's just as good as any other intake

If i leave the air mass sensor on, or whatever its called, there shouldnt be any malfuctions or engine lights coming on right? When my friend made his own intake his car black smoked until it adjusted for the new air flow.

Perhaps true. It's easy to "build" a more efficient air intake. The HARD part, and why cars have this little sticking point called software, is to get the engine to work more efficiently with the increased flow. Generally, most engine software will bring the entire fuel/air ratio back to balance by playing with the other settings, such as fuel delivery. You can roll your eyes all you want, but I very much doubt you will get more horsepower building your own intake. Even many aftermarket intakes, that advertise being "custom designed" for your particular car, actually create LESS horsepower than the stock airbox. There's a very good white paper about this sort of thing on Dinan's web site. Start there.

While this may be true, it's nothing that upgrading the rest of the compenents (Bigger injectors, etc) Won't help smooth out. A proper tune and you're good to go. Intake, Bigger intake manifold (assuming you're OBDII, you can swap in the M50 OBDI manifold), and bigger injectors to help balance out your fuel/air ratio, with the proper tune, could yeild a gain.
