Building your own intake is not only satisfying, but usually cost-effective as well. Do you have the ability to do mandrel bending and such? Because if not, some local performance shops surely do, and they typ do a great job with intakes and such. When it really breaks down to it, an intake really is just a coupling, bent tubing, and the filter. The filter is the biggest decision IMHO. So many different types on the market. You can always get a K&N filter and custom build your actual intake On my next build everything is going to be custom fabricated. Intake, Turbo/IC piping, exhaust. There's no reason not to
Originally posted by MILOTEKDo you guys think building your own intake would be just as effective as purchasing one from K&N or a comoany like that?
It's pretty much all about limiting the restriction in the air flow. As long as the diameter of the piping is equal or greater than that of the name brand, then you're good to go. You mention that the bending is limited, this is another area where you would want to ensure that you're using mandrel bending so that it doesn't kink and maintains the diameter of the tubing through the bend. All name brand intakes will do this, just a thought
Originally posted by MILOTEKSince I'm just doing a short RAM it will not require too much bending. My only concern is that a custom intake will not produce as much whp as a name brand intake.
Is the MAF a suck through or blow through? Its weird that the placement would affect how it reads.
Originally posted by talonIVDo you know anyone with an SPT intake? Or maybe you can find the dimentions somewhere? I know that would be a great design to follow. The only pain I could think of by making your own intake is placement and design of the MAF sensor on a Subaru. I have heard moving the MAF further down the intake tube can mess with your AFR's a bit on a WRX... Not sure exactly how true it is but with the quirkiness of a Subaru PCM i'd belive it haha.
Oh that is the MAF? I can see location being a big deal then. It doesnt have any honeycombs or venturi to regulate the airflow.
Originally posted by talonIVIt is held into the intake with 2 screws. From everything I have read up on pipe size and placement of the sensor will affect the readings...
