Agency Power Porsche Panamera Turbo Carbon Fiber three inch Y-pipe intake dyno results
Here are dyno results on a Mustang dyno of the Agency Power carbon fiber y-pipe intake for the Porsche Panamera Turbo. The stock plastic piping is 78mm at the throttle body inlet but goes down to a much more restrictive 51mm diameter at the y-split. This is a significant point of restriction in the stock intake system. The Agency Power carbon y-pipe features a three inch pipe diameter all the way to the factory end piece connection to the intercoolers.
Peak horsepower increases on an all wheel drive Mustang dyno from 388 at the wheels to 414 to the wheels for a gain of 26 all wheel horsepower. There are gains through the entire rev range. It would be nice to see an independent dyno to confirm these numbers not just from someone who sells this part. If the gains are accurate, this part is definitely worth the $1500.
