| Check out the stats: [ http://content2.us.porsche.com/prod/911/turbo.nsf/usaenglish/technical_specifications911_turbo_coupe ] They weigh about the same as the Z (they're a little bit heavier), and have about the same power as a Stage 3 Z. A stage 3 should give it a run for its money. A Stage 5, depending on what you call stage 5, should outrun it. They have 415 hp and 415 tq at the flywheel. With an 18% tranny loss, I have 413 hp and 474 lbs of torque at the crank. They are also permanent 4 wheel drive so they'll have a much higher drivetrain loss.
