Meh, not so much. Properly built P-Ports can run high enough in the RPM band that when you shift, you're still high enough. At the local auto-x where I was a regular MANY years ago, the guy that got the most FTD's was a 13B P-port in an FB (of all things) He would rev the SNOT out of that motor.
Regardless though, if you're going to go bridge-port, the factory intake won't be tuned properly anymore so in that regard, yeah a p-port would make more sense. Driving it to and from the track though..... I dunno about that. Although the FB guy did ever single weekend he was at some event.
Some food for thought, take it as you will, don't forget prices when you see these numbers
Stock S5 160 BHP
Friends S5 with Rtek, and RB full dual exhaust - ~175 RWHP
Bridges........ generally not much more
I haven't seen the dyno sheet for an FI P-port, but my EMS guy claims - 380BHP (on methanol)
