nice looking mod, how does it sound / feel?

Hi Darkii, I have mixed feelings about the mod even though I have been planning this for a long time....will let you know next week after I have run this for a while

wowoowwo ram air !!!!

wowoowwo ram air !!!!

Followed Mr A's advice....struggled to find writeup for this mod, so I struggled along...keen to know what my advisor would think:rolleyes:

[tony1234]

Don't want to be negative and i hope you prove me wrong but i think the gain will be minimal.:(

[Quest]

You are not being negative, but being cautious...which I appreciate. As I haven't come across any post on the net with this setup, I decided to give it a bash. Motivation was:

Comptech with debaffled smooth internal box with funnel in the bumper...I have done the rib removal of the box and extended the funnel to catch more air....if Comptech's design requires a cold air feed, then why not make it better?

This is still a gain, and could work better once further mods are done.

With my current setup (freeflow exhaust and Uni-Q piggyback ECU) and driving around for 3 days or so, the open pod with heatshield felt a lot stronger to me.....I might change to this with the cold air feed to test if this would work better.....maybe it's the fact that the pod is exposed to ambient air? Was also considering semi enclosing the pod so I still get ambient air and the direct cold air feed....there are many options,,,,I'm just glad that I can choose which one works best for me in any stage of development.

[DLO01]

Is the box totally sealed bar the intake hole. Is the pvc piping going in to the box and sealed in to the box?

[felixd]

you can gain small power by removing the fins off the box ive done dat. i guess with the ram setup u'll minimise the low end power.
try a more skinny conical type of filter like the S2000 has maybe that would be better :)

[Quest]

Yes, box is sealed and only air coming in is via the stack....I dremel'ed the periemter of the ex panel filter to re-use the rubber seal


Is the pvc piping going in to the box and sealed in to the box?.

Yes, the pipe is wedged into the existing rubber arm at the end of the box

All pvc joins are sealed with pvc glue

[Quest]

That is 60% done already, got lazy (time consuming with dremel)....I had to remove the internal cross brace for the pod to fit in

The pod is a tight fit in the box....I'm also thinking that air may not be circulating fast enuff....debaffling the remaining 40% of the box will help....my K&N pod has a 100mm inlet as well

[felixd]

with mine one i remove all the fins top n bottom of the air box . now ive got CAI just for the engine bling sake :D

[DLO01]

So thats the PVC pipe is run in to the box and sealed? Pic does not show that.

Thanks man. :thumbsup:

Looks like a good setup. Well done! ;)

I'll take some better pics of the details

Thanks....a lot of sweat went into it

[euro1603]

Well done, nice mod! I have the exact same euro model as you and I was tossing up between doing a similar mod or a cai..

I have that setup on my civic, but rather then the pod in the OEM box i just replaced the the filter with a k&n replacement. Not being negative and each to their own opinion, be prepared to clean that filter quite regularly. On the civic i had the intake inlet pipe just like yours next to the fog light. As you can imagine the light attracts bugs like a mutha.. and mine actually had a mesh up front to block out the chunky bugs.. I would recommend you put a mesh at the front. Personally i would have opened up that area to the right of the fog light,put a mesh at the back and then the pipe inlet. that way it will still catch the air front on and a bit more concealed.

One thing for sure, you will feel the difference and should some pretty nice..

Well i got my cai today, i'm expecting to loose some low down torque, hopefully the top end gains is worth it, otherwise i'll be same mod as you..

So whats the latest feedback buddy ?
Are you getting better mileage with this mod ?

Probably worse mileage since he would be using more throttle and hard acceleration to hear the intake. :p :thumbsup:

Well done, nice mod!....

Thanks

That was my previous mod, but as the effect of the velocity stack was not being optimised, I moved it.

Here was the old motivation http://www.ozhonda.com/forum/showthread.php?p=1846743#post1846743

Hard to tell, as I had half a tank of fuel when I did the mod..so the bottom half has promarly been used to test performance not fuel economy. Most peeps on the net indicate that the combination between SRI and CAI is the best of both worlds, but I've haven't experienced this....though the car runs a lot smoother, the low down grunt I experienced with the semi closed open pod has dwindled, and is motivation to try something else... :

To keep the cold air feed as is, but to revert back to the semi enclosed pod. I want to try the semi enclosed pod to test if more cold air gets forced past the pod in a semi open environment.....I'll be trying to copy the J'S Racing solution this Sat.

Right on the 2nd part, but I have a suspicion that fuel consumption is actually better....will test the theory when a full tank is filled

Your dog is awesome!

[curtis265]

interesting mod, good to see more creativity going on :)

[Crapdaz]

how many bends do you have from the trumpet?
looks like around 4 bends....

nice dog too btw,
and it's a creative mod....

[Quest]

Your dog is awesome!

"Lady" was donated by a family member to us....she's a poser that manages to get into all my shots

Thanks Curtis...

3 bends...1 @ the trumpet, 1 near the fog light and 1 further up near the hole in the fender


nice dog too btw, and it's a creative mod....

Thanks, she likes the attention...little does she know how popular she has recently become.

Thanks for the 'creative' compliment, I like to 'steal ideas from many' to create my own

Nice work. Good to see people sharing their DIY mods :thumbsup:

Thanks, I think you will find it hard to find a mod identical to mine, if you do send me the link :angel: cos I would like to know what the next person experienced

[corn_flakes]

where did you get that stainless steel pipe from? i see your pipe is slightly bent going into the airbox and assume a straight pipe won't work?

also, what's the diameter of that pipe?

[Quest]

where did you get that stainless steel pipe from?

From an exhaust shop, it was madrel bent to 15 degrees....I measured the bend

A straight pipe may work to the ex airbox, but that would mean interferring with the design of the flexible rubber arm


also, what's the diameter of that pipe?

100mm O/D and the K&N cone has a 100mm inlet:wave:

[hooyn]

maybe... if you have a few pipes joined together, to make the first couple pipes larger in diameter and not use that black pipe. the serrated surface of the edge would created some friction on the edge of the airflow.

having a larger diamter going into a smaller diamter would increase the air velocity as it travels from large to smaller diamter.
