Coming to us from NY, Mark’s 2005 Infiniti G35 arrived with a full tank of 93 octane gasoline. We proceeded to load it on the dyno at our facility in Louisville, KY for a complete dyno tune. After calibrating drivability and low boost tuning, it was time to see what the 3.5L built VQ35 could do. The commands were sent down the line, from Hal to the Haltech, to the boost controller, to the wastegates… and the twin 58mm Precision Turbos were brought up to ~20psi. The result was an impressive, record-setting 742HP at the wheels and 592TQ. Congratulations Mark on a well put together setup and truly impressive numbers on a pump gas 3.5L VQ build.
