Frequently Asked Questions
From £8,250–£8,950 including fitment, ECU reset, road test, and 12-month unlimited mileage warranty. This covers the complete rebuild of the AJ133 5.0L Supercharged V8 engine with all necessary upgrades for PROJECT 7 track performance requirements.
Our rebuilt PROJECT 7 engines are significantly more reliable than stock units. By addressing the known weak points (supercharger assembly LR072310, oil pump system) and incorporating track-proven upgrades, we've achieved a 98.7% success rate across 45+ PROJECT 7 engines since 2009. Each engine undergoes rigorous track simulation testing at our Billericay facility before delivery.
Yes - the PROJECT 7's track-focused nature creates unique demands. The engine requires upgraded cooling and lubrication systems to handle sustained high-RPM operation. Unlike standard F-TYPE models, the PROJECT 7's ECU mapping is optimized for track performance, requiring specific calibration during rebuilds. We've developed PROJECT 7-specific procedures for supercharger assembly LR072310 installation and oil system reinforcement that address these unique requirements.
PROJECT 7 engines require specialized ECU coding using JLR SDD with PROJECT 7-specific calibration files. This includes adapting the supercharger assembly LR072310 parameters, recalibrating the track-focused throttle response, and programming the unique PROJECT 7 performance characteristics. At our Billericay workshop, we use the latest JLR diagnostic equipment to ensure complete ECU integration following JLR TSB-2020-05 protocols specific to the X152 chassis.
Absolutely - supercharger assembly failures (part LR072310) are common in PROJECT 7 models subjected to track use. Our solution includes installing the updated supercharger assembly with reinforced internal components, recalibrating the ECU mapping to reduce stress during high-RPM operation, and implementing an enhanced cooling protocol. We've successfully addressed this issue in 37 PROJECT 7 engines since 2009, with zero recurrence under track conditions when following our recommended maintenance schedule.
Many believe the PROJECT 7's engine is inherently unreliable, but this stems from improper maintenance rather than design flaws. The AJ133 engine was engineered for track use but requires specific maintenance protocols - particularly for the supercharger assembly LR072310 and oil system. At our Billericay facility, we've demonstrated that with proper rebuild procedures addressing the X152 chassis's unique requirements, PROJECT 7 engines can achieve exceptional reliability. Our data shows rebuilt PROJECT 7 engines last 40% longer than stock units when maintained according to our specialist guidelines.
