what is it?how do i do it? and does it help
air box mod?
- Thread starter crawlinbusa1320
- Start date
I researched this a bit before deciding against it.. I ride pretty much only on the street and so I like having low end torque available.. The mod may make a few more total ponies but it will borrow them from the low/mid range (where I spend most of my time)..
If you are drag racing, it simply removes a portion of the airbox to allow a bit more free air flow at high engine speeds. This however lowers the velocity of the air going through the box at slower engine speeds. (can cause a loss of power at these lower speeds)
I have not been able to verify any of this but it is how it works on cars with 4 hole throttle bodies

depends if you plan to do the small box or large box mod

easiest and cleanest way to cut your airbox is with a modified soldering iron.

Flap opens at 2k rpm any way...why bother?

because you can flow more air, and its a bit higher than 2k rpm. But your exhaust and fuel needs to be able to match the incoming flow or you lose power in areas of the powerband hence way I say leave it alone normally.

How much more air by chopping up the box?
Ok, 2200 rpms...I verifed it...

honestly? I have never seen specs where guys flowbenched the box at various stages to know for sure.

okay...I knew it was between 2-3k rpms. I figured it was closer to 3 than that...but okay...I trust ya. A few hundred rpms won't matter anyway.
that's what I used for mine. Then sanded any doo-doo spots and again applied some soldering heat to melt/smooth things out.

depends if you use a pencil or a gun. I use a pencil type (cheapo $3 Harbor freight unit) and make an angled blade looking tip. Doesn't smell all that great but does a very nice job.that's what I used for mine. Then sanded any doo-doo spots and again applied some soldering heat to melt/smooth things out.
When I did the small box mod, it almost felt like the bike was more responsive and smother at idle.

Its not more responsive, and it got "smoother" because it got richer thus lost power.
How did it get richer if you are letting more air in?
Answer, because at low RPMs/speeds the air isn't being moved as it would at high speeds through those small RAM air tubes. When it does, the turbulence sort of chokes your box. This is overcomed as speed/RPM increases.

thats why you need the pc3 and proper map ..
