Evolution MotorSports Porsche Cayenne Turbo and GTS
The Porsche Cayenne Turbo gets a software tune that yields a gain of either 65hp/86lb-ft (48kW/116Nm) or 70hp/93lb-ft (52kW/126Nm), depending on whether it's tuned for 91 or 93 octane fuel. Adding the EVOMS V-Flow air induction system boosts power by 82 or 91hp (61/68kW), and 103 or 110lb-ft (139/149Nm) of torque, again depending on the grade of fuel. Pricing for the software tune alone is $3,500, while the V-Flow intake will cost $695.
For the Cayenne GTS, the same approach was taken, but smaller gains are available from the direct-injected 4.8L naturally aspirated engine. Base tunes yield either 19 or 21hp (14/15kW) and 22 or 25lb-ft (30/34Nm) of torque, while adding the unique intake system bumps the gain to 27hp or 29hp (20/21kW) and 29 or 31lb-ft (39/42Nm) of torque. The GTS kit is more affordable at just $1,800 for the ECU tuning and the same $695 for the intake.
Other components that can be optionally added to either vehicle include a sport exhaust, intake plenum, custom aerodynamic parts and wheels by Techart, and the shop's own EVOMS carbon components.
