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.

Nick Williams 112mm LT Throttle Body
Buy Now: $899.99

Nick Williams Performance drive-by-wire throttle bodies are CNC precision-machined from billet aluminum to meet the demands for increased airflow on the drive-by-wire LTX performance engines. The 112mm throttle bodies require an aftermarket intake or adapter plate to fit the larger diameter throttle blade. They use a 6-pin late model connector that works with late model wiring harnesses. The Nick Williams Performance drive-by-wire throttle bodies come completely assembled with bolts included.

For use on the LT5 supercharger, an adapter plate is required for clearance. Of course, additional porting will be needed on the blower snout to optimize performance and clearance for the throttle body blade.
