The 5.8 is formally known as the Trinity Engine or 5.8-liter V8 engine, which benefits from cylinder heads with improved coolant flow, Ford GT camshafts, piston-cooling oil jets similar to those found on the 5.0 Coyote, new 5-layer MLS head gaskets, an over-rev function that increases the red line to 7000 rpm for up to 8 seconds (from 6250 rpm), and a compression ratio increased to 9.0:1 from 8.5:1. Displacement is 5,812 cc (5.8 L; 354.7 cu in) with a bore x stroke of 93.5 mm × 105.8 mm (3.68 in × 4.17 in). Boost is supplied by a 2.3 L TVS Supercharger with maximum boost of 14 psi (0.97 bar). Trinity has 37 mm (1.5 in) intake valves and 32 mm (1.3 in) exhaust valves. Nearly every part of the powertrain was optimized for producing the additional horsepower. It was used in the 2013 and 2014 GT500.
