Technically this is a kill story with a video for proof, so...

Both Porsches run low 12s @ 116mph +/- stock; basically identical times and trap speeds.

Round 1 - 60 mph roll or so. GT3 gets the jump, but the turbo reels him in.
Round 2 - 70 mph roll - turbo all the way.
Round 3 - 45 mph roll - turbo still pulls

Specs (stock):
* '01 911 turbo - 415hp/415tq - AWD - 3395 lbs
* '04 GT3 - 381hp/280tq - RWD - 3048 lbs

Mods:
* turbo - exhaust (add in heavy, 19" wheels that hurt acceleration)
* gt3 - intake
