991 Project Car Exhaust Upgrade is Underway
We are really excited about the development of this Vivid Racing Project car. The second this thing was in the shop we started the R&D. The process of development is to track progress through every phase. We got her on the dyno when she arrived to get the baseline’s out of the way. Vivid even had fun testing her doing the 1/4 mile on the dyno. From there we will continue forward to test the exhaust and other parts progress as we move forward. We will start with the muffler and factory cats, then OEM muffler with high flow cats, and muffler with high flow cats. But we aren’t stopping at the muffler. We have some awesome tubular manifolds in the works as well as, a ton of turbo and intake manifolds.
Here’s a quick sound clip teaser we thought we would post of the progress thus far. You get to the product in its rawest form, and it looks sexy. We are so pumped to see the final result, but we’re having fun in the process. If you scroll you’ll get some awesome behind the scene shots of us at work making the products you know and love.
One of the new parts we are working on is the βchargeβ 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 2 inches diameter, and then merges fairly early. To improve upon this design, we have increased the diameter of the piping to 2.5 inches and maintained separate pipes as close to the throttlebody as we could to eliminate any unnecessary turbulence. The piping is designed to still work with the factory air box and maybe (spoiler alert) 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!
