Third-party K-series dyno data from the guys at GO Power Motorsports. Check out GO Power's Skunk2 Pro Series Intake Manifold dyno results on its 2.4-liter, 12.5:1 K-series engine. GO Power left all variables alone and simply swapped Honda's RBC intake manifold for the Pro Series version. A factory, 64mm TSX throttle body was used for all tests. Similar to what Skunk2's dyno data reveals, GO Power found horsepower gains from 5,400 rpm with a significant increase past 8,000 rpm. The results are even more impressive once a larger, Pro Series Throttle Body is added along with more aggressive cams.
