Bonjerno Roberto,
I've been lucky enought to travel to your beautiful country a few times in the recent past. Brindisi was very nice. Good people and some of the best food and wine in the world!
I first modified my airbox using a hole saw as outlined here:
Hole-Saw (my post is about 2/3 the way down).
Not too long after posting that I opened the bottom hole up even larger with a Dremmel tool being careful not to destroy the small protrusions in the bottom of the box that center the filter. I had to rejet the mains to 132.
Since then I performed major surgery on the airbox with the
Ghetto Freak airbox modification and had to rejet to 150's and I'm acutally considering a little larger (may be 155's).
My Ghetto Freak talking paper in pdf format is also located in the
Tech Vault.
One of these days I'll have to break down and pay for a dyno to compare my current configuration to stock numbers and enable fine tuning. The difference between the amount of air the holed box passed and the pod filters pass is apparent due to the necessity to increase jet size (132 to 150s) to mitigate popping on decel and ensure proper plug coloring.
Just my input ......
Regards,
Tom
