EDIT: Leaving the original text below, but just wanted to write up front that I recently found that my active runners aren't actuating. Will update once I correct the issue.
Hi all. I've recently installed short tube headers and the 392 active runner intake manifold on my 2016 R/T, and the great news for everyone here is that I've got before/after dyno results to share! Please check out the attached photograph which I painstakingly angled to capture a reflection of the car in the glass.
The upper plot shows horsepower while the lower plot shows torque as a function of engine speed. The red curves are the car's baseline performance before the intake and exhaust mods were installed, and the blue curves are after install and tuning on the same dyno. While I only got a few horsepower increase at the peak, the horsepower stays higher beyond the peak and I picked up a ton of power across the low- to mid-RPM range. I spend most of my time in the 2-4K RPM range, so I'm pretty happy with the extra 25-30 horsepower in that range.
For reference, my headers are JBA 1964S-1JS ceramic-coated short tubes and my intake manifold is programmed to actuate the runners at 4600 RPM. I'm also running a Corsa 14985BLK Xtreme catback, but the catback is present in both the before and after runs. Hope this is helpful to anyone considering this modification combo.
