Here is what Porsche says about their tuned intake:

"The Boxster inherits its twin-resonance air induction system from the 911
Carrera. The system acts as a “resonance supercharger,” allowing the engine
to draw from higher velocity airflow at certain engine speeds. A crossover pipe
connects the individual air collector/resonance chambers for each cylinder bank.
A flap in the pipe remains closed from idle to about 3,100 rpm. When it opens,
each cylinder bank can draw from airflow “excited” by the resonance created by
alternating induction between all six cylinders. In essence, “dual resonance”
creates two induction paths for each cylinder. Below 3,000 rpm, the cylinders
draw air from a “short” path. From 3,000 rpm to about 5,100 rpm – when the
resonance flap opens – the cylinders draw from a long intake path, which
boosts torque. Above 5,100 rpm, the flap again closes to allow the cylinders
to draw intake air from a shorter intake path to boost horsepower at higher
engine speeds."

They don't address that little res. box specifically but others in this forum have removed it, dynoed and lost torque and HP. I gotta believe it is a small part of their tuned intake system. The GT3RS has 3 res. chambers. Somebody thinks they are important. It's sort of like tuning a subwoofer cabinet. You adjust cabinet volume, dampening and port size to maximize certain desired frequencies (or RPM's).

Does this make any sense to anyone or am I just a lone voice deep in left field??
