I can't recall seeing anyone do this.
In my opinion, I would probably just go the pulley/tune rout if you have the stock blower, and I'm sure Whipple has the blower setup like they would like it. I know some alot of the 03/04 Cobra guys did it, but with the twin screw and the abundance of power available with small changes I wouldn't put it high on my list of things to attempt.
