Rod Summers races his 2003 Infiniti G35 in time attack. The car visited his employer Z1 Motorsports’ dyno to prep for an upcoming event. It’s powered by a 3.7 L VQ37VHR V6 featuring Deatschwerks 600 cc injectors, Z1 Motorsports oil cooler and 3-inch carbon fiber intakes, and custom 3-inch exhaust. It made 342 horsepower and 287 lb-ft of torque. Rod also upgraded the six-speed manual transmission with Z1 Motorsports clutch, flywheel, and heavy duty billet CSC kit.
