Optimum operating range is 6000-8500 rpm and is primarily intended to bridge the gap between N/A and Boosted applications. It utilizes the high LT1 throttle body position and will accept DBW or cabled throttle bodies*, but yet it will fit in the tight confines of the C7, C6, C5 Corvette as well as the popular F-body platforms. The design incorporates 2 runners and an interchangeable plenum. The seal is generated by 8 entrapped o-rings at the runner/plenum interface, and is clamped by 20 -M6 Stainless steel socket head cap screws. The port seals are achieved SAE o-rings seated in a dovetailed o’ring groove. The TRInity incorporates two 1/4-27 NPT ports on the side of the throttle body boss and a 3/8-18” NPT on the rear. This listing is for the manifold in Black Satin Texture powder coat. The manifold comes semi-assembled and includes all the hardware required to bolt it on.
