Fitting a Lohen Performance Pack 2 to my R59 Mini JCW (Stage 2) _UNBELIEVABLE RESULTS
**Article: The Transformation of Ruby Roadster - A Comprehensive Journey Through Modification**
---
### Introduction
In this article, we follow the journey of a Mini Cooper owner who decided to take their car modification aspirations to the next level. Referred to affectionately as "Ruby," this roadster undergoes a series of transformations at Lowen, a specialist workshop known for its expertise in tuning and modifications. This is the first installment of a video series chronicling the entire process, from initial tests to final results.

### Arrival at Lowen Workshop
The day begins with an excited arrival at Lowen's workshop. The owner has been planning this moment for years, always fascinated by the idea of enhancing their Mini Cooper's performance. The car is checked in and a detailed job sheet is reviewed. Ruby is prepared for rolling road tests to establish baseline performance figures.
---
### Initial Tests on the Rolling Road
Before any modifications are made, Ruby is placed on the rolling road to measure her current power output. The owner had initially expected around 211 horsepower but was pleasantly surprised when the car delivered **238 horsepower and 300 Newton meters of torque** during these tests. This strong performance sets a solid foundation for future modifications.
---
### Pre-Modification Checks
The team at Lowen is meticulous in their approach. Before proceeding with any work, they conduct several crucial tests to ensure Ruby's engine is in optimal condition. These include:
1. **Compression Tests**: Each cylinder is checked for proper compression, ensuring the pistons and engine internals are healthy.
2. **Exhaust Gas Testing**: Using a specialized tool, the team checks for exhaust gas leaks in the cooling system. If present, these can indicate serious issues like blown head gaskets.
3. **Leak Test**: Compressed air is introduced into each cylinder to measure air leakage through the valves. Ruby passed this test with only **6-9% leakage**, well within acceptable limits.
These checks are essential to avoid putting unnecessary stress on the engine during modifications, which could lead to costly repairs or complete failure.

### Exploring Modification Options
With Ruby cleared for modifications, the owner and team discuss the best approach. The owner opts for a **Low End Performance Pack Level 2**, which includes:
- A Stage 2 remap of the ECU.
- Replacement of the downpipe with a high-performance sports cat-back exhaust.
- Installation of a larger intercooler to improve airflow and reduce intake temperature.
- New spark plugs to optimize fuel delivery.
The owner also mentions they considered upgrading the front bumper with JCW GP2 scoops but decided against it due to delayed delivery. The focus remains on maximizing performance rather than aesthetics for this phase.

### Modification Process: Intercooler Upgrade
One of the most significant upgrades is the intercooler. The existing unit, while functional, is quite small and limits the car's potential under heavy load. The new intercooler, nearly four times larger, promises to drastically improve cooling efficiency and allow for more aggressive tuning.
The process involves removing the front bumper, replacing the old intercooler, and reconnecting all necessary hoses and pipes. This upgrade is critical for maintaining stable engine temperatures during high-performance driving.
---
### Modification Process: Downpipe Replacement
Next up is the downpipe replacement. The original cat-back exhaust system is removed, and a new sports cat is installed. This change not only enhances the car's breathing capabilities but also adds a more aggressive exhaust note, complementing Ruby's sporty demeanor.
The team ensures that all connections are secure to prevent leaks and maintain optimal performance. The exhaust system is tested for proper function before proceeding further.
---
### Modification Process: Stage 2 Remap
At the heart of Ruby's transformation lies the ECU remapping process. This involves connecting the car's computer to a specialized device, which uploads new software instructions. These updates optimize engine timing, boost pressure, and fuel delivery to maximize power and torque output.
The owner eagerly awaits the results of this critical step, knowing it will unlock significant performance gains. The remap is completed without issues, setting the stage for final testing.
---
### Post-Modification Testing
With all modifications complete, Ruby is ready for a road test to evaluate her new capabilities. The team takes her out for a spin, carefully monitoring her behavior under load. Despite some challenges due to rain, the car performs exceptionally well, showcasing the effectiveness of the upgrades.
---
### Dyno Results: A New High
The final step is a dyno test to measure Ruby's updated performance figures. The owner had hoped for around **265 horsepower and 400 Newton meters of torque**, but the results exceeded expectations:
- **270 horsepower**
- **395 Newton meters of torque**
These figures are a testament to the comprehensive modifications and thorough testing process conducted by Lowen's team.
---
### Conclusion
The journey of transforming Ruby Roadster into a high-performance machine is complete. The owner expresses gratitude to the Lowen team for their professionalism and attention to detail. They also emphasize the importance of considering warranty implications, insurance updates, and choosing reputable specialists when undertaking car modifications.
Ruby now stands as a testament to what can be achieved with careful planning and expert execution. As the owner drives home, they reflect on the decision to invest in this transformation, knowing it was well worth the effort. The next chapter of this adventure will explore other toys and opportunities, but for now, Ruby is ready to deliver thrilling performance.
