Re: Air Intake Questions
So I was wondering about air intake.. i was browsing around ebay and found this:
http://cgi.ebay.com/ebaymotors/BCP-0...Q5fAccessories
and i was wondering.. do any of you have this? is this any good?
i just dont know how to tell whats good and whats not good..
if you have changed urs, what kind do u have?

For a far amount less, you could get a Weapon R SRI. ILl try to find the link , but I got mine for no more than $190

---So out of alll of these, which would you say is the best one to get? And what are you guys' thoughts on Injen Air Intakes? that was my first initial one i wanted to get bc i just love how it sounds and looks in the engine bay. and again, im not looking for performance. i dont drive a race car here.. lol.. just tryin to make it purr pretty. anyways, let me know
and thanks again to all of you for the help.

Re: Air Intake Questions
i like how that looks ALOT. and not a bad price either.. thanks for finding that for me..
yeah, that's not bad either.. dont you have the weapon-R one ^ up there?

I also want to note, that my Megan strut bar still fits with my Weapon R intake without hitting my hood.

Personally, I love my Weapon R. I cant speak for everyone, but it sounds pretty damn good, and I swear I could feel a difference. (Probably just a placebo, but who cares) You could pair the intake with a magnaflow catback, and it would purr nicely. One thing to note though, your intake will look a little different than the one in the photo. Its on its third redesign. Ill post some pictures today to show you what mine looks like.

hey - since we are on the subject - could you tell me more about the magnaflow catback? what is the difference between a catback and an entire exhaust system? or is there one.. i know this might be a dumb question. but hey.. if i dont know, might as well ask so i do know.. thanks for any help

Re: Air Intake Questions
As the name says
Catback = all the way from catalytic converter to exhaust tip
Axelback = from your rear axle to exaust tip (basically muffler only)
A complete exhaust setup would probably start from the downpipe, to the kitty, to the muffler and exhaust tip.

Re: Air Intake Questions
i dunno if i have ever heard one.. ill have to see if i can find a video or soemthing online.. and yeah, i'd appreciate a pic of it.. i would, in time, wanna get a strut bar too, and i'd want one low enough not to hit anything. from that pic though, it looks pretty damn good.

Since I've been planning to swap on and off since I bought my car, I don't have any engine mods. Just a bunch of k-series parts in my closet.
I like the plastic one because it performs better than any other intake and not that many people have it. Purely from a sound and cosmetic perspective, the weapon-r is one of my favourites next to the v2.

sweet. see? didnt know.. and now i know. thanks for helpin me out..
so.. when you say.. You could pair the intake with a magnaflow catback.. you obviously would have the intake set up.. and then with this catback, you would have that set up all the way from the cat to the exhaust, to the muffler? or would you also need a muffler and what-not?
what im tryin to do is figure out the whole system that i'd want. all the things needed for it, and what parts are needed together.
and also, where does a header play into all of this? is this just optional for more power? or more air flow?
i know im playin 20 questions right now, but i really do just wanna know and learn all this stuff instead of being blind and asking everyone what the hell things are.. lol

A scene before your eyes
Re: Air Intake Questions
I was thinking about how frikin sick it would look if a half inclined mechanic would design a scoop that could be opened and closed at will from inside the cab. Closed- no water, no snow, no Powerrrr. Open, lots of fresh air, mm.. mm powerrrr. The only time you ever see this is on superchargers. I wonder.......

As for your header question, the exhaust pulses in sinusoidal waves. If designed correctly, each pulse of exhaust gas will aid in pulling the next exhaust pulse away from the engine. Typically, this occurs at 90 degrees in a 4 cycle engine. The DC Header, like the one in my car has equal length tubes that converge into a single merged collector, which creates a smooth transition into the cat coupling. It also has the same diameter openings as the exhaust ports on the engine head, reducing turbulence and maintaining optimal pressure, required for extraction of heat and gases. Although the gains from an aftermarket header are minimal on D17A2, the design pulls heat away from the engine better than the OEM exhaust manifold (hence, no heat shield) and is a better design than stock, at higher RPMs. The OEM manifold is an unequal length extractor tube design, with an unmerged collector. Think four drinking straws shoved into a can of Coke with different lengths vs. four equal length straws that have the ends cut at 45 degree angles, glued together, then molded into one big straw, then custom-fitted onto a coke can top. Which design do you think would give each person drinking, the same amount of liquid with each slurp?
Forgot to mention that the reason why gains are so minimal on a stock engine is that the D17 is designed to save gas. Duh, I know. But simply stated, the intake and exhaust cycles are designed with minimal waste, no overlap, just enough to burn the gas completely and extract. Simple and efficient. The intake and header don't really come into play until the profiles of the cam are changed to allow more air in and the exhaust pulse can pull the next pulse sooner. More air in and faster gas out equals POWER. That's why the stage 1 cam makes so much of a difference. Don't even think about putting in a cam without upgrading your intake, header and exhaust or IHE. That would be cutting your potential short. Only thing missing is more fuel. That's where a tune with a computer comes into play. More gains. But that's another topic.

It's powdercoated gunmetal, double walled aluminum. Some heat protection, but it still gets hot.

The other pics have them on right place, so it's ok
Sinusoidal... Are you another dang engineer too?!?
Anyway, fer lower power engines I usually prefer 4-2-1 headers, but not sure how they work with the rev happy hondas... The fact it's hard to find them might answer it tough...4-1 just works for the D17.

They'll work, just not legal (in CA anyways) - Kinda gets rid of the cat. I'd die to get my hands on a TODA Racing 4-2-1 Header for the K20.
I thought hard about installing the DC 4-2-1 on my D17, but I didn't like the thought of getting my car impounded by the police WHEN I get pulled over again. I'm a magnet for some strange reason. Last ticket I got, was going 70 in a 65. Seriously?
I'm too dumb to be an engineer. Trust me I'm surrounded by them.
Speaking of which, I gotta joke:
How can you tell when an engineer is an Introvert or an Extrovert?
He's an Introvert if he looks at his shoes when he talks to you. He's an Extrovert when he's looking at yours.
TAP TAP TAP Is this thing on? Tough crowd tonight...

Yeah,not sure if losing the cat for a 1lbs gain in lower range would be worth :P

True that, but on a high rev monster like a moded K20 (9000+ RPM), the 4-2-1 design alleviates the pulses counteracting/bouncing back on one another so close to the head, especially with an aggresive cam profile. I wont even get into VTAK. Think of 4 on-ramps onto a single freeway at rush hour within 1/4 mile. Better take that crap further down the road, another mile or so...
This is easy compared to V8s. That's just insane. Pulses vary from 90 to 180 degrees, for each side, crossovers for pressure equalization, etc. Now that takes some skill.

I enjoyed the engineering joke, they're an odd bunch, despite sharing a number of courses with engineering students I never find myself talking to them. Aside from when they take the time to point out my degree is useless, that is.. who needs marketable skills anyway, pfft!
