Wring More Power from Your Chevy LS/LT Engine with Performance Design Carbon pTR Intake Manifolds

Performance Design has risen to the top of the Chevy LS/LT marketplace by designing, engineering, and producing intake manifolds and accessories that are as functional as they are attractive. 

Carbon pTR Intake Manifolds
Performance Design Carbon pTR Intake Manifold air plenums are constructed from high strength, five-layer carbon fiber to be lightweight, strong, and reduce heat soak of the fresh air charge. PA6GF30 glass-reinforced nylon polymer lower manifolds resist cylinder head heat soak in addition to hiding all the ports and sensors in the lifter valley. This combination of materials delivers a ten pound weight savings over aluminum tunnel ram manifolds. 

Another feature of these intake manifolds is the unique modular velocity stacks. You can swap between 6.5-, 8-, and 9-inch long stacks so you can tune your engine’s power curve to your cam, head, and exhaust combo. For example, if you want to make maximum power at high RPM, use the short runners. The long runners improve mid-range torque, whereas mixing the runner lengths can help smooth out the torque curve. 

Other features of Performance Design Carbon pTR Intake Manifolds include:

• Raised velocity stack entries
• Forward facing throttle body flange accepts 102-105mm throttle bodies
• MAP sensor locations in the front and back
• Two 1/4-inch NPT ports for PCV, purge solenoids, or other accessories
• One 1/2-inch NPT port for brake booster or IAT
• 16 nitrous nozzle bosses on outboard and valley side of each runner
• Provisions to run three injector body lengths
• Manifold can be mounted reversed on the engine
• Tested to over 50 PSI of boost
• Anodized billet aluminum throttle flange
• Shipped with long runners installed; medium or short velocity stacks available separately
• Includes molded port, plenum, and throttle seals and stainless steel mounting hardware

Performance Design Carbon pTR Intake Manifolds are available for Chevy LS1/LS6, LS2, LS3/LS7, LT1/LT2, and other LS-series engines with cathedral or square port cylinder heads. The tall height of these manifolds allows them to be used on restomods, off-road race trucks, race boats, hot rods, and additional vehicles where hood clearance is not an issue. They can also be used on late model vehicles if a hood scoop is fitted. 

Billet Fuel Rails
You can forget about fuel rail fitment issues with your Carbon pTR Intake Manifold by using matching Performance Design Billet Fuel Rails. They are available in your choice of black or red anodized finish and come with stainless steel mounting hardware. The rails use commonly available -8 AN port inlet fittings, sold separately.

Carbon HR Intake Manifold Lids for Holley EFI Intake Manifolds
Replace your heavy cast aluminum Holley EFI intake lid with a lightweight Carbon HR Intake Manifold Lid. Constructed from high-strength carbon fiber and bonded with high-temperature aerospace structural adhesive, it’ll knock three pounds off the top of your engine. Carbon HR lids also reduce heat soak, and the exposed weave cloth finish improves looks and tells onlookers you’re serious about your car’s performance. Additional features include:

• Throttle opening is moved up and rearward to improve flow into the plenum
• Allows plenum to be mounted reversed for better engine compartment packaging
• Accepts 90-105mm throttle bodies
• Available with black or red anodized billet aluminum throttle body flanges

Performance Design Carbon HR Intake Manifold Lids will bolt to any existing Holley Hi-Ram, Mid-Ram, or Lo-Ram cast aluminum lower intake manifolds.
