Carbon HR/pTR Hybrid Intake Manifold Kit Cathedral Port
Buy Now: $1,499.99

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.

Carbon TRc Intake Manifold LS1/LS2/LS6 Cathedral Port

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, LS3/L92, LS7, LS1/LS2/LS6, Godzilla, Coyote and Hemi all using the same carbon fiber plenum.

Carbon pTR Intake Manifold Base Only
Buy Now: $699.99

The Carbon pTR Intake Manifold combines the best materials into a flexible and powerful tunnel ram architecture. Glass reinforced nylon lower and carbon fiber upper 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 offers easy configuring for any hot rod setup.

Shipping with the longer runner, optional velocity stacks offer different lengths. Tuning of the intake runner length to match the cam, head and exhaust combo gives the ultimate way to optimize your engine’s power curve. Shorter runners support high RPM drag applications or longer runners for improved torque in the mid-range. Mixing lengths can help smooth out the torque curve.

Does not fit underhood on late model vehicles; best suited for resto-mod, off-road race trucks, race boats and hot rods.

Specifications & Features

-BASE ONLY -
-Modular velocity stacks for 6.5”, 8.0” and 9.0” runner lengths
-Raised velocity stack runner entries
-PA6GF30 Glass filled nylon lower manifold for light weight and low heat soak
-Two MAP sensor locations (front and back)
-Two 1/4 NPT ports for PCV, purge solenoid, etc.
