what's your airbox mod?

[whileoceanasleeps]

thinking of modding my airbox soon, so just wondering what your setup is in regards to airbox mods? I know there's a few different ways.. cheers

Once upon a time I though holes and cutting away sections was best, so my dyno graph said.


Then I cut away a little bit more, and my power was down.


After research and more research, and speaking to some people (people who actually know), I came to the conclusion that a sealed airbox, with the inside smoothed and the intake pipe on the inside rounded off and one or two sealed cold air intakes, giving the airbox more air than it's using, is the best method. It might not sound as loud as a drilled airbox but performance-wise it's the best setup.

I got a 80mm hole saw and made the standard intake hole 80mm 
Then got the trumpet from the top half of the air box and cut the trumpet end off. I then sealed the it in the 80mm hole with silicone and got a 80mm hose.

I need twin Hellas to make my second air box

Elaborate.

Do you mean removing the offside spotlight and using that as a cold air intake? That's what I wanted to do, but I think it's illegal to remove one of the spot lamps.

That's exactly what I want to do. And I got a grill that takes hella lamps  ugly as hell but will still have 4 lamps but 2 massive cold intake holes. I got 100mm trumpets that I got from empty electrical wire boxes from site. That I will mould/fibre glass in.

I've got a garage full of air boxes and bits of tube, holes are deffo sh!te as is any unshielded filter in the engine bay.
The rest is a question of how much time and money you have vs what sort of power gains you want from the N/A abf.

err not much money a lot of time. just want more power and efficiency and noise!

Two of them words go together and one doesn't belong in that sentence.

Modified sealed box keeps efficiency and gains power but no noise.

Noise looses efficiency in case of cone filter, but drilled box will have no effect, but it will loose power.

You pick what you want.

having a 1.4 i might aswell start blowing air in the intake myself but decided to get a cold intake pipe and smooth then drill my box it makes it sound louder but performance is none.

it all comes down to noise or performance.
