Hi Paul - as I now have such a miniscule battery, I have the opportunity to do something like this (below). With a heat shield behind the cone and an extra air intake from the bumper to feed the cone compartment, do you think it would work? Or would I lose low down torque?

Gotchya, thanks Paul.

Do you seal/arrange the pulse traps to generate a vacuum on the positive pulse and suck out (buffer) the return pulse with the vacuum generated ?
[I know there is lots of ways of doing pulse traps and many are designed to just flow better in one way than another (eg a simple step) rather than use a vacuum. I think of one as passive and one as dynamic]

Perhaps you could combine SRI + pulse trapped airbox + ramair

Have you toyed with using a ramair system for exhaust extraction ?
I know overlap is an issue so perhaps this will boost the low and midrange power...especially at speed..perhaps with wilder cams ?
Like we pulse tune using exhaust from one cylinder to extract the other...use ramair instead to extract the whole exhaust.
Do it right and you could use the high drag areas on the rear with high pressure zones on the front for a much better effect.

That's a very interesting idea with the exhaust but we also have a big challenge of trying to keep the noise to acceptable levels.
Lots of scope for development though and something I think Mark and Sam were exploring on the Lotuss

Was funny playing with the intake as we had a big plastic bottle and we were chopping it about trying to find a volume that worked best. Also played with 2 ports connected to the reservoir. Real 'Blue Peter' testing!

Andy - yeah as long as we can get good clean air feed.

.

Pics or it didnt happen

Whats the chances of one the US 2006+ SI kits fitting the FN2 guys, RHD of course

I think the first bend comes in too soon on the Import DPS one, it doesnt look right (post 73 page 4 on the link below) itd need to be longer first section from the TB with a shorter middle section like this:

Custom 3.5 inch intake - 8th Generation Honda Civic Forum

Check out post number 52 on page 3 for the finished install

What about something like this with a 3.5 in and out , fitted were the battery is ?

[civi08]

We'd really be looking at something as already suggested mate, filter in a location where cold air can go directly thru fog inserts and be sucked in. I wouldnt want to be paying for carbon/kevlar either, that bumps up cost big time and neither tdi or cpl would be able to create it. Simple 3.5" pipe with a cone filter will suffice.

[mw1978]

guys 3'5 intake designed for US SI will not fit. They have larger engine bay.

[civi08]

Is yours a custom build marcin? Looks like the one in my link above, very smooth weld-less looking 3.5" pipe

[stoney]

who made yours MArcin, can they make more, how much ?

[mw1978]

this is my work LOL. 100% custom. I bought pipes on UK ebay and pouder coated to match with blower.
Its very hard to fitt that pipes behind front lamp so decided to use two pipes with difrent angle and silicon conector. Cone filter is very big and has velocity stack. On the last picture You can see what i have to protect my cone filter against water...

[civi08]

This ftw

I know carbon/kevlar would be far to dear , but would love a open cone in a closed box 3.5 in and out , fog light scoop into the bottom of the box , box were the battery is , so it would be a breeze to change the filter , with out having to take the bumper off job to change a filter . Think I'll make another attempt at a system like i am looking for . Just let me know what kind of cone filter and size i need , and were to relocate the air sensor

[mw1978]

i have seen that pics many times when i thought about my intake. That pipe is too long and in my opinion intake pipe in one pice is impossible to fit in FN2
Even If you fit that one pice pipe think how You change bulps in lamp???

[civi08]

Yes i know, that isnt a kit that you can buy. Its an example of something we could recreate over here but that DOES fit the fn2. Its the basic design i like and would work good aswel as look clean in the engine bay.

[stoney]

Marcin thats fabulous work mate

Steve, I'll have a chat tomorrow about an idea I have that might help you nothing to man of your abilities and your welder weilding friend down the road

Marcin

If you don't mind me asking where did you source your velocity stack and filter, any part numbers, pipe angles and lengths etc would be appreciated too pal

What size pipe, stak and filter is that marcin ?
Thats almost exactly what I need on the derv.
Has to be 72mm ID on the tubing for the MAF sensor though.

[stoney]

All different sizes on ebay uk Mick. Im already on this lol

[mw1978]

guys i used two 45 degrees pipes. Bouth 89mm
I bought my cone filter from USA and dont remember dimensions
You can compare my cone with old injen. Whole intake (pipe) has about 55cm
