Airbox modification..

[RagingAngel]

cut the same hole in my bumper recently... didnt notice too much diference though

two main reasons why you won't feel much.

The hole you opened up might be stalling. Think sticking your head out the window of a moving car, the faster you go, the harder it is to breathe right?

You need something that can effectively scoop the air, like a velocity stack

The other is, if you were able to properly ingest more air, the ecu is probably not compensating for it enough....you can only determine if it's being effective by checking the plugs for more of a lean burn...or installing a wideband O2 sensor to see if the AFR at speed is changing.

thanks ragingangel.
As said, i have recently added a velocity stack in the hole adding a direct pipe into the filter. Recently posted a pic of my spark plug and its light grey = lean. Does this mean that ive properley ingested more air?
what else can i do to check whether it has made a difference?

 

[RagingAngel]

plugs are a good enough indication. If you have the ability to richen the mixture, give it a shot and see if you feel any gains.

I probably missed it entirely, but which v.stack did you go with?

Pics of your setup babyface?

As for the rubber arm. Samco has something.

Honda-Tech.com: Acura Integra Type-R: SAMCO INTAKE???

that samco rubber arm is awesome,, i`m thinking samco rubber arm in black, BPI velicity stack + filter & fabricate up my own mugen style airbox oh heatsheild that side of eth bay off above teh chassis leg,,

 

[cingli]

will the samco rubber arm for the dc2 fit the ek9?

it wont fit to the standard filter but i am pretty sure it would mate up to a mugen

ragingangel: how would i richen the mixture?

do you have a mappable ECU? if so you can re map it, if not other options woudl be an adjustable Fuel pressure regulator and up teh fuel pressure sligfhtly, personally i think thats a bit of a crude way to do things though..

firstly i woudl get teh car hooked up to a wideband AFR gauge and take it for a spin on teh road, or get it strapped down on a dyno to see if you need to do anything..

where abouts are you based? i have a wideband AFR innovate LM1 but i am based in devon

 

[babyface]

ahhh. thanks for the offer olly , but unfortunately im in surrey ..

im assuming that dc2 pipe wouldnt mate up to a spoon kevlar pipe either then??

dont think so teh dc2 airbox is further away from the throttle body in teh first place,,see here....


steves ek9,,

an ITR

just bought my bpi velocity stack and filter,, going to be doing something similar to teh mugen intake, watch this space, i`ll start a thread in projects once i get going..

i may have use for that simota ss tube lying around the garage, rubber pipes reduce the resonant frequency on the intake as rubber is a natural sound damper, by installing a solid tube you keep the resonant frequency high in the intake & gain a couple of hp just by swapping rubber to aluminum, SS or PVC pipe.

i doubt itl fit a mugen intake in a 9 then because the spoon kevlar bit is where the mugen velocity stack will be - in fact lookin at the two pics i think itl be a lil long...

anyone have a teg hose and a ek9 hose they can measure? as really wanting one if itl fit to my mugen in the 9

i think you may need to cut teh velocity stack piece down,,
here is a mugen intake,,,

and here is a teg engine bay again

as you suspected

hmmm - not sure i would like to cut it - just in case i have to sell it later on...also im lacking the tools as suffice to say im not the best equipped around here

The mugen velocity stack on the ek9 is a lot longer then the dc2 as well...im in two minds at the moment - what is the flexibility of silicone piping and any chance itl just pull over the velocity stack?

other option would be to cut the samco,, it is the cheaper of teh 2 parts after all,,,

true...cheers olly - i just fin installin aerocatch bonnet pins myself so feeling braver now anyway

well we've finally done it, took only a few hours but it's done.

Overrev Tuned homemade CAI

debris catcher removed for increased volume & resonance

OEM intake tube cut & welded shorter

K&N drop-in is used for filtering, can you say Mugen CAI rep.

up next we'll replace the stock rubber tube to a solid PVC tube, gonna scrounge the local hardware stores for the right size tubing.

i am such a cheap bastard.
