Thanks! This explains quite a lot.
This list is like the Master's program for the Vmax.

Subject: Re: Airbox "Y"
The U. S. also has restrictions on how much "intake" noise a imported
vehicle can produce. I have heard some say that is the reason for the two
1" intake holes on the Max. I do not know how much water this holds because
the air box is the same at all locations in the world.
I think the intention was for low end torque. A motor is basicly an air
pump right? Soooo the more air you can get through it, the more horse power
you can produce. This is true for top end. BUT the oppisite is true for low
end. Case in point, if you look at drag motors that spend 98% of the run at
high RPM they have big valves, ram intake with twin carbs, and 1' pipes
bolted to each exhaust port to route the hot gases away from the motor.
I.E. the least restriction as possible. If you look at thier dyno sheets,
they don't start making horse power, relatively, untill high RPM's. Then
again if you look at the hill climers, off road trucks, they have
realitively small valves full exhaust and smaller carbs. They make all
thier torque at the lower RPM's. It has to do with the velosity of the air
moving through the motor. The faster the air the better the atomazation of
the liquid gas in to a gasious from, the better and more efficient the bang.
Smaller valves, intake, an!
d carb gives higher intake fuel/air velostiy = better low end performance,
BUT on the other side this limits how much air you can get through the motor
= poor top end.
Torque = acceleration
HP = Top Speed
The Max was desgined for 1/4 mile acceleration. I think that was the
intention behind small intake. I have a Holeshot 4-1 exhaust, with both an
air box lid and K&N trimed to provide maximum air flow. My max is an
absolute dog below 3,000 RPM's but at 10,000 RPM's makes about 12 more horse
power than a stock Max. It just depends what you want to do.
