After letting the car cool completely, we brought coolant temp to 160 degrees to make each pull. Before, it made 504 rwhp and 434 lb-ft of torque. After installing the new intake manifold, without changing anything in the tune, it made 522 rwhp and 455 lb-ft of torque. Power and torque were both up throughout the curve, not just up high in the rpm range. Improved airflow reduced our boost pressures from 20 psi to 18 psi. To make up for the loss in boost, we added 2 degrees of timing, resulting in 552 rwhp and 474 lb-ft of torque. Though Johnson won’t run it like this on the track, it’s easy to see this intake’s potential on the street.
