Gary has one of the new 2010 Roush Mustangs that comes with a built motor and 2.3L TVS R2300 Roushcharger supercharger kit. From the factory it makes a ton of power but there was still some room left.
Stock it made 510RWHP and 493RWTQ, they only rate this motor at 510 crank HP but it makes that to the wheels.
With a custom VMP dynotune it picked up 16RWHP peak and 27RWTQ peak, but the most impressive part was the mid-range power gains. It picked up 67 foot pounds of torque in the 4000RPM area.

Next we went from a stock 3.1" upper pulley down to a 2.8" upper pulley, this change normally adds about 1psi per tenth of pulley size. However, we found out the factory intake was very restrictive, we picked up lots of mid range power but only a little bit of peak power.

I am working on a way to improve airflow of the stock airbox since it is a very nice piece to begin with:

I also have high-flow inlet elbows/plenums and 72mm throttle bodies that I developed for the GT500 TVS on the 5.4L 4V which will also fit the Roush TVS on the 4.6L 3V since it is the same blower, we may look at trying some of those parts in the future.
