Im going to try and design some parts so that i can build a dual cold air intake similar to the needswings kit, id like to keep it under $200 to build if possible. parts that I will try design and print are the intake Y, the tube connectors that are usually made of silicone, and the ducts in the grill. if anyone would like to help, i could use it lol. Im planning on using a nylon filament that should hold up to 220-230C but im also going to keep researching materials while im designing it. ive never designed anything from scratch, only modified others 3d models, so well see how this goes!

Brave new world! I have often eyed the Needs Wings product, but it seems like a lot of money for the modest power gain. If you can come in cheaper, I am very interested.

I’m teaching myself to 3d model stuff throughout this project so it may take a while on my own. I know there are some 3d modeling softwares that allow you to test airflow through a part, but it’s a little complex. I’ll update the thread once I finish the very basic 3d design sketch for the Y tubing, I started working on it today. I might have to start out with just a single filter design with a bent tubing that goes over the maf. I’ll update this thread as I figure out designs etc. I know it can be done I’ll link some examples, the only issue is with heat, the filament I want to use can withstand up to 240C but I may need it to hold up to at least 250-260C I’m assuming it gets pretty hot under the hood in air temps over 100F, I’ll have to stick a thermometer in there this summer.

Cool project

Get a Dyno reading before, then after, and might also be worth comparing to the proven gain V6 320 W220 Intake / Filter Box mods

Keep us posted

That’s a good idea, but I can’t afford much dyno time right now, I’m a student and I already spend too much on my car lol. Best I can do right now is log MAF readings, it should show an increase if it opens it up more. I’ve almost gotten to a point on the bend to the maf where I can print a prototype, and I think I may end up using a flexible material, called PCTPE for the final print

It's far from an idea, it is a basic requirement when Tuning

MAF reading does not indicate more or less engine power, too many variables, at the end of the day the golden rule when modifying any Engine is to establish a base line first and work from that, making one change at a time

I've seen many a modified Engine that has had a whole bunch of Horsepower "Engineered" out of it when actually run on a Dyno

If the Needs Wings one is proven to increase power then an exact copy should do the same. But with a single offset bent intake V6 intake airflow direction is critical and technical to design where the bend is influencing flow direction into the throttle body.

 

[Dave2302]

I've discussed this before.

I agree with you re airflow direction into Throttle Body, I've seen many folks overlook that.

Further to that, amongst pro tuners around the world it is a known fact that the "claims" for this and many other performance mods are based on Hood (Bonnet) up testing from a cool engine.
When the Bonnet is closed heat soak takes over and negates any improvement, in fact I'd go so far to say it would actually have a negative effect until one insulated or properly cooled the install.

Just my 10p worth
