BTR Trinity Intake Manifold | LS Cathedral Port
BTR Trinity Intake Manifold | LS Cathedral Port
Overview
BTR Trinity Intake Manifold — LS Cathedral Port is the cathedral-port version of Brian Tooley Racing's modular Trinity intake system, supplied through Harrop.
The BTR Trinity uses a short-runner, three-piece cast-aluminium architecture designed to bridge naturally aspirated and boosted LS applications. BTR specifies the manifold for an operating range of approximately 6,000–8,500 rpm and supports both drive-by-wire and cable throttle-body arrangements where the correct hardware is used.
Construction & Features
- Three-piece cast-aluminium design with interchangeable plenum architecture
- Eight O-rings sealing the runner-to-plenum interface
- Twenty M6 stainless-steel socket-head fasteners clamping the runner / plenum assembly
- SAE O-ring port sealing in machined dovetail grooves
- CNC-machined port mouth radius and port match
- Two 1/4-27 NPT ports beside the throttle-body boss
- One 3/8-18 NPT rear port
- Black Satin Texture powder-coat finish
- Semi-assembled supply with required manifold hardware
Fuel-System Integration
An optional BTR fuel-rail kit is available separately. Injector, rail, throttle-body and vacuum / sensor configuration must be planned as part of the complete induction and fuel-system package.
Installation Notes
Confirm bonnet clearance, throttle-body diameter and actuation, injector height, fuel-rail configuration and engine-management requirements before ordering. Professional installation and calibration are recommended for performance applications.
BBT Support
Built by Boost & Tune can assist with manifold selection, fuel-system configuration, installation, fabrication and dyno calibration.
Fitment
For compatible LS engines using cathedral-port cylinder heads. Confirm the exact cylinder-head port architecture before ordering.
