that makes sense...

Hi folks, sorry, so the hole around the side of the air box, does the elbow go back on this, obviously with the odd shaped piece removed??.
May just be me not getting it :-) but what was the blanking off on the elbow referring to??, the small hole but not the larger one?.
Cheers, Jim.

I'd not have thought it'd make noticeable difference day to day

that airbox resonator... well:
Adding an expansion chamber to the intake tube forces air coming back out of the engine to slow down to fill the cavity, thus expending a great deal of its energy and slowing the pressure wave reversion. This slowdown allows fresh air to flow toward the engine without fighting pressure reversion waves the entire way, thus aiding in cylinder filling. Since these pressure waves are essentially sound, giving them a place to expend their energy before exiting the air filter box ends up dampening the intake noise and quieting the engine. Thus, the resonator helps to make the engine paradoxically quieter and more powerful.

This makes a lot of sense.
I assume having an intake plenum like the FRP makes the resonator do nothing, removed by Tickford as part of the engine mods?

I've just smashed the resonator out of my 1.7 airbox, much more room now ! And when the box is in place there's a pipe that goes into the right hand side, then runs above the wheel arch lining and past the coil spring into the bulkhead area, I put a cold air feed pipe on there and ran it straight to the lower grille on the bumper so.it sits next to the rad but will have more air straight to it. Is that where the box draws cold air in as I can't see any other openings that it could draw air from.

Have had the mod done a while now but it’s become more prevalent in the recent floods that the original input hole was allowing water into the box via the wheel well and making her splutter a bit. Karl also had this problem. Even with arch liners in place. Had a look and there is actually a small drainage hole just inside it anyway so I have chosen to blank the original input off as it still has means for drainage.
PS. A Pringles lid fits snugly with a bit of hot glue to secure :wink:
