What to do when you want a Porsche 911 Turbo and that wind-in-your-hair experience, but the 480 horsepower that comes stock isn't enough? Well, you dial up TechArt, which has just pulled the wraps off a cabrio version of the menacing Turbo-based GT Street. The ragtop, like the coupe, makes a ridiculous 630 horsepower, and while TechArt hasn't officially announced the torque figure, we're assuming it's also upwards of 600 lb-ft. So, if you're in a rush, there's no need to reach for that blow dryer. Just head out to the car, put the roof down, aim it where you want to go, and punch it. Your hair should be bone-dry by the time you hit the quarter mile mark or so. If it isn't, just keep pushing -- it'll finally top out at 214 mph. Your 'do might look like this if you hit maximum warp, though, so use your judgment when applying pressure to the loud pedal. We'll have full specs on the GT Street Cabrio when TechArt formally introduces it in Geneva. Until then, you can see the coupe's numbers here.
