IPD 991 TURBO/TURBO S PLENUM
Porsche’s 9A1 flat-six delivered big power for the second-generation 997 Turbo and its successor, the 991 Turbo, which promised close to 550bhp in Turbo S guise. This new plenum from IPD is designed for force-fed 991s and is offered as a 74mm version of the firm’s 997 Gen II offering, allowing the continued use of the factory throttle body. 991 Turbo intake manifolds are smaller than previous designs, which is great for improved boost response and mpg, but less than ideal for those of you wanting to enjoy substantial power gains. IPD’s offering provides more than adequate airflow for these more restrictive intake runners, eliminating the need for a larger ‘competition’ throttle body. The patented IPD design improves power and torque over all factory power curves from launch to redline, providing a longer and more desirable power band. Maximum power increases take place in the midrange, where it’s most needed, most critical and, importantly, most enjoyed. The host 991 Turbo will adapt to the new hardware through a series of spirited driving sessions or hard pulls on a dyno.
