Here's the setup I used to run, very close to the Cup racer setup and similar to a B16/B18 style Honda induction kit.
Made fantastic torque and power, here's some comparisons between the setup above and the V6 Airbox with 90 degree bend I ran previous to it.
Before Setup
After setup
Not a great deal of difference in power (only 1bhp), however a massive hike of 5+ lb/ft of torque for essentially just changing the induction setup without specific calibration either. Both setups were complimented with...
Matched Inlets
Decat-back Exhaust
Same RSTuner map
So with a specific calibration it could well of made more power and torque, so can perfectly understand how that chap made 10+lb/ft of torque and a power increase in going from a shocking filter setup to a good setup.

p.s. Will have to add pictures when i'm back from working away, for some reason its not working...
