It’s time to choose the centerpiece of your boosted engine build. Second to only the supercharger or turbocharger, the intake manifold will be the focal point of your build illustrating the power and strength of what’s underneath. Billet aluminum is the usual choice for performance and a beautiful aesthetic, but is there another? Is there something more distinct, ultra-modern, elegant, individual, lighter and at a lesser cost? The Carbon TRc (Tunnel Ram compact) intake manifold is an evolution of our Carbon TR naturally aspirated and Carbon TRic (intercooled) boosted intake manifolds. The new TRc is an under-hood, short runner intake manifold optimized for boost, but does not rule itself out of a naturally aspirated application where fitment and aesthetics are preferred over peak torque.

The Carbon TR has been a fan favorite since inception due to its elegant carbon V twill down the center of a double-bubble upper plenum. However, its large and complex, billet aluminum, 5-axis CNC-machined base made it costly to manufacture and did not allow it to fit under most factory hoods. This led us to start with a clean sheet of paper design, while evolving the TR’s aesthetic into the next generation. The key hallmarks of the new design were to maintain the carbon fiber and billet alumnium construction, manufacturability within a desired price target, fitment under the stock hood, and versatility of subcomponents to be used across a wide range of applications.

To achieve these goals, we arrived at a modular design starting with a carbon fiber one-piece molded plenum. Carbon fiber braided sleeve layers with alternating weave directions are wrapped around a bladder and inserted into a billet aluminum mold where it is pressed against additional hand-laid carbon fiber fabric and infused with resin. Vacuum is applied to the carbon-filled cavity while pressure is applied to the internal volume, the bladder, and the entire tool is heated. Using this process, the tool itself becomes an autoclave and thus achieves autoclave-level part quality and strength. The resulting plenum is a strong pressure vessel without seams or bonding making it capable of handling over 50 psi of boost.
Runners are CNC-machined, 6061-T6 aluminum manufactured in two pieces to sandwich the plenum. A short velocity stack plate is installed inside the plenum and the outer runner bank bolts through the carbon fiber plenum into the velocity stack plate and is sealed with o-rings. A billet aluminum throttle body flange is bonded to the front of the carbon fiber plenum with aircraft-grade adhesive. Billet aluminum fuel rails are also available for port fuel applications or to add port fuel to direct-injected applications.

This modular design allowed us to develop the Carbon TRc quickly for a wide range of applications including LT1/LT4, LT2, LS3/L92, LS7, LS1/LS2/LS6, Godzilla, Coyote and Hemi all using the same carbon fiber plenum.

Carbon HR/pTR Hybrid Intake Manifold Kit LT1 L83 L86 L87
Buy Now: $1,599.99

The Carbon pTR/HR hybrid uses our Carbon HR upper combined with the nylon lower from the pTR for reduced height in constrained applications (see layout drawing tab). Short velocity stacks are provided to clear the plenum which results in a total runner length of 6.5". Long and medium velocity stacks will not fit in this application.

The product is sold as an unassembled kit. You will receive:
-Carbon HR with black anodized billet aluminum sealing plate
-pTR lower assembly to suit your application
-Short velocity stack kit
-Stainless steel hardware
-Gaskets and seals

Follow standard Carbon pTR assembly instructions found in the upper right corner of this page.

pTR Intake Manifold LT1/L83/L86
Buy Now: $1,099.99

The pTR Intake Manifold offers tunnel ram architecture at an affordable price. The pTR family of intakes includes Carbon pTR (nylon lower manifold with carbon fiber plenum) for all LS and LT engines and now pTR (all nylon) for LT engines. Glass reinforced nylon upper and lower shell combine for lightweight, strong and heat resistant performance. Offering unique modular velocity stacks enabling 6.5 – 9” runners, multiple accessory port and sensor options along with other custom features, this manifold is now offered for the Gen 5 LT1, L83(with upgraded throttle body) and L86 engines.

The plenum is constructed from molded nylon for a reduced cost alternative to the popular Carbon pTR. The same polymer lower runner pack resists heat soak from the heads and houses all ports/sensors hidden in the valley. The combination of materials offers a 10 lb weight savings over competitive aluminum tunnel ram manifolds.

Add port injection to supplement or replace the Gen V LT’s direct injection with optional billet -8AN fuel rails.

Specifications & Features
•Modular velocity stacks for 6.5”, 8.0” and 9.0” runner lengths (tuning required for 6.5” and 8” runner)
•Raised velocity stack runner entries
•PA6GF30 Glass filled nylon lower manifold for light weight and low heat soak
•PA6GF30 Glass filled nylon plenum
•Rated for 45psi of boost
•103mm forward facing throttle body flange
•Two MAP sensor locations (front and back)
•Two 1/4 NPT ports for PCV, etc.
•One 1/2 NPT port
•Canister purge solenoid mounting provision
•Includes stainless steel hardware for installation
•Nitrous nozzle bosses on outboard and valley side of each runner (16 total)
•Provisions to add port injection with billet fuel rails (sold separately)
•Includes molded port, plenum and throttle seals
•Intake can be reversed on the engine
