The only phrase that comes to mind is that we are “balls deep” in the R&D process of aftermarket performance parts for the Porsche 991 Turbo. We have completed the exhaust system with high flow catalytic converters and thought we would do a sneak peak sound clip. The exhaust system, as described here in our previous article, will be tested on the dyno as well as reviewed for driving characteristics on the road. The exhaust will be tested in stages as muffler with factory cats, OEM muffler with high flow cats, and muffler with high flow cats. In addition to the exhaust, we also have tubular manifolds in the works and several turbo/intake components.
One of the new parts we are working on is the “charge” pipe or Y-Pipe that goes into the throttlebody. We have been very successful in the past with Y-Pipes on the Panamera Turbo, 996 Turbo, and 997.2 Turbo gaining proven horsepower on the dyno and quicker turbo spool for normal driving characteristics. The amount of air flow you can get into the throttlebody is more important (IMO) than what happens after the throttlebody. The increased airflow simply yields more power and performance. On the 991 Turbo, the factory pipe from the intercoolers to the throttlebody is 2inch diameter and then merges fairly early. To improve upon this design, we have increased the diameter of the piping to 2.5inch and maintained separate pipes as close to the throttlebody as we could to eliminate any unecessary turbulence. The piping is designed to still work with the factory airbox and maybe (insert Dr. Evil pinky face) a new cold air intake. Stepping up our Agency Power game is this nice CNC machined AP logo brace in the center. Of course non of this is important unless it makes power and improves driveability so stay tuned for those tests!
