Performance Design's Carbon pTR Intake Manifold combines high quality materials into a flexible and powerful tunnel ram architecture. A glass-reinforced nylon lower intake and carbon fiber upper shell combine for lightweight, strong and heat resistant performance. Offering unique modular velocity stacks enabling 6.5" to 9” runners, multiple accessory port and sensor options along with other custom features, this manifold offers easy configuring for any Cathedral Port LS setup.
The plenum is constructed from high strength carbon fiber with high temp epoxy for improved strength to weight ratio and reduced heat soak. A polymer lower intake further resists heat soak and houses all ports/sensors underneath the valley for a clean look. This combination of materials offers a 10-pound weight savings over aluminum tunnel ram manifolds. Tuning of the intake runner length via optional velocity stacks enables matching the intake to your cam, head and exhaust combination, giving ultimate power curve optimization. Shorter runners support high RPM drag applications, while longer runners improve torque in the mid-range. Mixing lengths can help smooth out the torque curve. These manifolds come from the factory with the longer velocity stacks installed for a 9" runner length which works great for most applications outside of ultra-high RPM racing use.
