Description
Performance Design Carbon pTR LS1 Intake Manifold - Black Flange Fits 1997-2013 Cathedral Port LS Heads LS1 LS2 LS6 LQ4 LQ9 L33 LC9 LH6 LMG Includes Lightweight Billet Black -8an Fuel Rails.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..-Modular velocity stacks for 6.5”, 8.0” or 9.0” runner lengths (Short and Medium length stacks sold separately) -Tested to over 50 psi of boost -Raised velocity stack runner entries -PA6GF30 Glass filled nylon lower manifold for light weight and low heat soak -Carbon fiber plenum with 5 layers of carbon.Black anodized billet throttle flange accepts 102-105mm throttle bodies -Nitrous nozzle bosses on outboard and valley side of each runner (16 total) -Two MAP sensor locations (front and back) -Two 1/4" NPT ports, One 1/2" NPT port -Stainless steel installation hardware included.Provisions for 3 different fuel injector lengths -Includes high quality molded seals for runner ports, plenum, and throttle body -Intake can be reversed on the engine -Includes PD's matching Ultralight Billet -8an Black Fuel Rails
