LS3 INTAKE MANIFOLD INSTALL

Again, these bars greatly assist with transitioning air from the plenum into the runners, maintaining maximum airflow and velocity.

Once all porting/grinding work is completed, we then install the same carefully selected radius bars that we use in the Rod-Mod. Next, we port the air inlet section of the manifold along with grinding/smoothing the injector bosses protruding into the runners. Once removed, we adequately seal the plenum floor back up, and slightly grind/smooth the floor of the plenum. These stands are large and very obstructive to flowing air. The Rod-Mod is ideal for forced induction applications, as well as nitrous applications as it does not compromise the structural integrity of the manifold during high-pressure events.Įst Gains: 6 HP for bolt-ons & 12 HP for cammed setups.ĭuring the “Ported-Rod-Mod” process, we begin by removing the vertical stands that run inside the manifold plenum. In addition, we minimally grind and smooth the area inside the runners where the injector boss protrudes into the runner, ensuring minimal disturbance to airflow from the injector boss. This helps to maintain proper airflow and velocity. The radius bars we install are carefully selected, measured, and cut to a specific length and assists in transitioning air from the main plenum into the runners. Through research and development, we have learned that air does not like moving over sharp turns – it creates unwanted turbulence.
