Subject: Sonic wave inside Miata :)

What a shocka!  While I test driving Momo chan with the new air box,
suddenly there was sonic shock wave at 3000RPM in second gear.   The
whole facia as well as glove box were rattled as if they were put next to
1000 MW speakers.   Upon arriving home, I checked the engine room to see
something was wrong before I dismantle the facia.  Shocka, shocka!  The
pipe connecting between the negine and the air flow unit was unpluged and
the engine was sucking air without air filter. :(  It seems the pipe was
partially attached and when the engine vibrated at certain RPM, it
resonated and hence the sonic shock wave.   I'll see if it's gone
tomorrow - it's too dark outside and beside I don't want to wake up
neighbours. :)

BTW, with the new box, Momo chan now has very distinctive deep bass sound
which I just love - I'm big fan of techno man.
