Roush DL50SRC 5.0L SR Coyote Supercharged Crate Engine

Description

Eliminate complex custom supercharger calibration with the Roush DL50SRC Supercharged Performance Crate Engine for modular Ford projects. Based on a modern 5.0-liter double-overhead-cam Coyote platform, this unit generates 750 horsepower at 6,500 RPM. A positive-displacement TVS supercharger packs dense boost into four-valve combustion chambers for instantaneous acceleration response.

An engineered 356-T6 cast aluminum engine block features cross-bolted six-bolt main bearing caps holding a forged 4340 steel crankshaft. Internal components include forged 4340 steel H-beam connecting rods and forged 2618 aluminum pistons inside 3.630-inch bores. Stroke measures 3.650 inches with a 9.5:1 boost-ready compression ratio, supported by an eight-quart rear-sump oil pan, weighing 530 lbs dry.

Key Features of Roush DL50SRC

Restomod builders buy Roush DL50SRC crate engine systems to install late-model supercharged muscle into vintage street platforms. Modern variable cam timing maximizes low-end torque while maintaining high-RPM breathing efficiency.

• 2.65-liter positive displacement TVS supercharger forces high-density charge air into cylinders
• 3.630-inch cylinder bores feature plasma transferred wire arc thermal coatings
• 3.650-inch stroke forged steel crankshaft handles extreme rotational torque loads
• Cross-bolted main caps anchor the rotating group under elevated boost pressures
• 9.5:1 forged aluminum pistons endure severe forced induction combustion heat
• Four valves per cylinder optimize incoming charge velocity and exhaust gas scavenging
• Water-to-air intercooler cores lower intake air charge temperatures before the intake ports
• DL50SRC calibration maps manage dual-fuel injection timing across shifting throttle inputs

Forced Induction Output Operating Profile

Operating across an RPM band of 2,200 to 7,000 RPM, this supercharged V8 outputs 750 brake horsepower at 6,500 RPM and 670 lb-ft torque at 4,500 RPM. Four overhead camshafts feature variable timing control with 0.510-inch lift on intake and exhaust valves. Designed for 93-octane premium unleaded fuel, the package sustains 16 in-Hg idle vacuum while maintaining 50 to 75 PSI hot oil pressure.

Transmission Fitment Modular Envelope Bounds

The modern Ford modular bellhousing bolt pattern matches Tremec Magnum XL six-speed manuals and Ford 10R80 automatic cases. Internal zero-balance components require a neutral-balanced flywheel or flexplate. The rear-sump aluminum oil pan clears aftermarket independent front suspension crossmembers engineered for Coyote restomod swaps.

Pre-Oiling Protocol Prohibited Applications

Pressurize the main oil galleys using an external accumulator before turning the starter to coat all four camshaft journals with synthetic lubricant. This supercharged unit is not engineered for marine seawater cooling, continuous boost beyond 14 PSI on pump gas, or unmetered nitrous systems.

• Dump the initial break-in engine lubricant after the first 50 road miles
• Change motor oil and filter every 3,000 miles using full synthetic motor oil
• Inspect supercharger drive belt tension and ribbed alignment every 12 months

Factory Warranty Coverage Complete Manifest

Roush protects this power plant with a 24-Month or 24,000-Mile factory limited warranty. Shipment crates contain the dressed supercharged long block, integrated intercooler system, standalone wiring harness, throttle pedal, alternator, starter, and certified dynamometer documentation.
