Awesome Speedart

Larger turbos and intercoolers along with ECU tweaks send the Porsche 997 over the edge with speedART’s BTR-II 650 EVO; it goes 0-62 in 3.2s thanks to 641 hp/479 lb-ft of torque.

SpeedART’s PS9-650 ups the sex-appeal of Porsche’s oddly-shaped Panamera not only with a slick aero kit but a tuned engine that pumps out 650 hp, good for a 0-62 of 3.5 seconds.
