Default Designing an Intake

I have a guy Va Beach that can fabricate just about anything out of plastic. I am thinking about designing a custom intake. What I am thinking about doing is trying to combine the Comptech with Spoon i.e. an extension from the Comptech box that goes down in front of the bumper.
Thoughts?

Have him design one in which the end of the pipe (filter) points downward so it doesn't fill up with water when parked out in the rain.

im currently trying to develope an intake arm for my mugen made of cf.
i have all the dimensions of this and have it designed through cad. all i need to do now is get someone or a place to do the molding of the cf into a solid piece.

how are looking to improve the Mugen? I think the J's intake has an advantage b/c of the "bulge" in the intake pipe, so if added that to the Mugen...you'd basically be making the J's intake.
I've thought about the HKS piping , but I would need the dimensions. Supposedly, they are tuned, like the AEM.

im not trying to make the arm the same as the j's. im currently trying to figure out
how i can get better air flow w/o using the j's design. so ive come to some sort of conclusion that i want the air to be cooler(cf) and i want more air flow so the piping will have a bigger diameter all the way to a 70mm throttle body(have you ever seen an iceman cai? kinda like that), then a cf intake manifold. my main objective is to keep the air cold the entire time until it actaully reaches the ports
ill have a 3d model done soon and ill show it to ya let me know what you think cause im always open to ideas

if ur talking to me......no im kidding.
i hope this works out and if so ill definitely make them for our community.
i jus want a real product thats gonna make gains or atleast show a positive diffrence in relations to the existing intake. ill let you guys know whats going on cause its my own money that im investing so its in the developement stages to where im gonna have to find a cf molder soon

hmmm.. I don't think that the air is moving "slow" enough to get really heated before making it to the throttle body. You will see temp differences, but whether or not they are really significant i.e. to justify a CF, larger bore pipe .... I don't know (leaning towards no). The larger bore intake may help, but material will have a minimal effect.
The issue to look at is (1) runner length ( and a way to get the benefit of a short runner vs. a longer runner.....which is neat thing about the HKS. I am wondering if they made all those crazy turns to get a longer runner. The problem being too much length/angle/diameter change (narrowing) is bad for flow.
Send me your design when you get it done. Myself, I am looking at a snorkel extention for the Comptech..... almost like a J's but with a bigger airbox.

i was thinking the same. As of right now i've been looking into the designs of both the j's and asm to see how air flow is manipulated jus through the first portion(intake arm). its not something i wanna jus make up like stock, its something i want to articulate to maximise the air flow in that portion jus as j's and asm did. thers alot of room to work w/ and alot can be done which is why im not satisfied yet
ill post up a render based on what i got

This is just a thought... but you guys should keep your ideas to yourselves until you get them built. Because if someone see's your idea and has the means to make it, there by stealing your idea, you'll have done the design work and they will reap the benefits

Just a thought Steve
