Roush 511IRFEP-C 511 CI Individual Runner FE Engine

Description

Master technicians deploy the trusted Roush 511IRFEP-C Crate Engine to conquer commercial long block repower challenges demanding all aluminum big block Ford performance. This 511 cid 8.4L FE V8 delivers 625HP at 5,800 RPM. Technicians must check front shock tower spacing because wide FE cylinder heads crowd vintage engine compartments.

Cast aluminum forms the Ford FE cross-bolted engine block structure with pressed ductile iron sleeves. A forged 4340 chromoly steel crankshaft anchors this Roush engine core. The 12V starter draws 195A during crank cycles. Dry weight measures 530 lbs with an unrigged stance of 30in length by 28in width by 29in height. Sump holds 8.0 quarts.

Key Features of Roush 511IRFEP-C

Plant millwrights buy Roush 511IRFEP-C Crate Engine units for severe industrial engine rebuild programs that demand massive big block torque. The eight stack electronic fuel injection system meters precise fuel charges into individual intake runners.

• Cast aluminum FE cylinder heads feature precision CNC combustion chambers that optimize flame propagation.
• An aggressive hydraulic roller camshaft provides broad power bands without manual lash adjustments.
• Eight stack individual runner fuel injection provides instant throttle response under all load states.
• Forged 2618 alloy pistons resist structural deformation under severe high combustion temperatures.
• The 511IRFEP-C commercial core holds 0.0020in rod bearing oil clearances under severe dynamometer testing.
• Cross bolted main bearing skirts prevent crank bore flex under heavy mechanical torque loads.
• Multi layer steel head gaskets clamp down to eliminate combustion bore leakage.

Dynamometer Bench Testing Thermal Ratings

Dynamometer runs record 625HP at 5,800 RPM and 650 ft-lbs torque at 4,200 RPM for this 511IRFEP-C long block engine. Gauge monitors record 60 PSI oil gallery pressure at 2,500 RPM at 195°F operating temperature. Cylinder compression gauges verify 195 PSI across all eight cylinders within 3% balance. Crankshaft journal runout measures 0.0003in TIR across intermediate journals. Exhaust gas temperature probes register 1,300°F during extended dyno testing.

Field Installation Preventative Maintenance Directives

Individual runner throttle crossbar mechanisms require 6 lbs return tension for positive closure against engine vibration. Mechanics must avoid this commercial replacement engine for vintage passenger car frames lacking reinforced front suspension towers or vehicles without high volume electric fuel pumps.

• Drain break in oil after 500 miles or 20 operating hours then refill with 15W-50 oil.
• Inspect electronic fuel injector seals for leaks before initial high pressure fuel priming.
• Check cylinder head fasteners at 85 ft-lbs torque following the initial thermal heat expansion cycle.

Crate Manifest Warranty Protection Coverage

Backed by the Roush build standard, this package features a 2-Year or 24,000-mile limited warranty. The rugged wooden shipping crate holds the complete engine, eight stack EFI induction, wiring harness, distributor, water pump, harmonic balancer, oil pan, plus signed dynamometer test sheets.
