GP Elite – Porsche engine cooling improved by 7.4%
Project: GP Elite Dyno Validation
Dynamometer validation of Synano’s EG50 nano-coolant in a Porsche 718 Cayman GT4 RS Clubsport
By replacing a conventional 50:50 water–ethylene glycol coolant with Synano’s EG50 nano-coolant, GP Elite recorded measurable thermal performance gains under controlled dynamometer conditions. Testing on a Porsche 718 Cayman GT4 RS Clubsport demonstrated up to 7.4% improvement in effective heat transfer and an average 12-second reduction in cooldown time per run. Results were consistent across full-power and constant RPM conditions, confirming that Synano’s nano-coolant extracts heat more effectively from the engine, clutch, and gearbox without altering the vehicle or its cooling architecture.

Cooling challenge
Racing cars operate under sustained extreme heat across multiple subsystems simultaneously. The engine, clutch oil, and gearbox oil all generate heat that must be extracted and rejected continuously. In high-performance motorsport, operating temperatures push close to component limits, and any reduction in cooling efficiency translates directly into reliability risk and performance loss.
GP Elite, a professional motorsport outfit, agreed to independently facilitate the validation of whether a nano-enhanced coolant could produce a measurable improvement in thermal management under controlled, repeatable conditions using an existing production-based race car with no hardware changes. The question was straightforward: does the nano-coolant outperform a conventional 50:50 water-ethylene glycol mixture in a real system, under real load?

Solution
Synano and GP Elite conducted dynamometer testing at Dekker Tuning Service on 3 December 2025, using a Porsche 718 Cayman GT4 RS Clubsport as the test vehicle. The protocol covered three test types: full-power runs from 2,500 to 9,000 RPM, constant-load runs at 3,000, 5,000, and 7,000 RPM, and post-run cooldown analysis. Each condition was run twice per coolant to ensure repeatability. Ambient temperature, airflow, tyre pressures, and vehicle configuration were kept identical across all runs.
Synano supplied both test fluids. The base coolant was a standard 50:50 water–ethylene glycol mixture. The EG50 nano-coolant used the same base fluid with Al₂O₃ nanoparticles, delivering 7% higher thermal conductivity and 1.5% higher specific heat capacity, with marginally lower viscosity. GP Elite managed all practical aspects of test execution as vehicle preparation, system flushing and filling, data acquisition, and throttle operation and provided the complete raw dataset to Synano for analysis. Coolant temperature, engine oil temperature, clutch oil temperature, and gearbox oil temperature were logged throughout every run.
Results
The nano-coolant consistently outperformed the base fluid across all test conditions and both runs at every RPM level.
Across constant RPM runs, oil cooling improvement reached up to 7.4% at 5,000 RPM. Results at 3,000 RPM and 7,000 RPM followed the same pattern: the average combined oil temperature rise was consistently lower with nano-coolant for a given time period at constant power input.
During full-power runs from 2,500 to 9,000 RPM, the nano-coolant reduced average oil temperature rise by 6.1 to 6.5% over the same 20-second test window. Engine, clutch, and gearbox oils all showed lower temperature gains, confirming that heat was being extracted more effectively from all three subsystems simultaneously.
Cooldown performance produced the most consistent advantage. At constant RPM runs, the nano-coolant reduced cooldown time by an average of 12 seconds per run, confirming faster heat rejection at the radiator. In full-power runs, cooldown time was reduced by approximately 52 seconds on average.
The nano-coolant also registered a higher coolant temperature rise than the base fluid, while simultaneously keeping component oil temperatures lower. This finding proved that the nano-coolant absorbs more heat from the system and transports it more effectively to the radiator for rejection.

- +7.4% improvement in effective heat transfer versus base coolant
- 6.1 to 6.5% lower average oil temperature rise during full-power runs (2,500 to 9,000 RPM)
- Average 12 seconds shorter cooldown per constant RPM run, confirming faster radiator-side heat rejection
- ~52 seconds faster cooldown in full-power runs, reducing thermal recovery time between cycles
- +7% higher thermal conductivity and +1.5% higher specific heat capacity versus base fluid
- Lower sustained temperatures across engine oil, clutch oil, and gearbox oil subsystems under all conditions
- Drop-in compatibility with no vehicle modifications, no hardware changes, no altering the cooling circuit
Conclusion
The GP Elite dynamometer test produced a clear, repeatable finding: Synano’s EG50 nano-coolant increases the effective heat transfer capacity of the cooling circuit under sustained high-performance conditions. Across every test condition, two runs each, and three independent RPM levels, the nano-coolant kept oil temperatures lower, cooled faster, and transported more heat through the system.
For motorsport, the practical outcome is more thermal headroom, reduced component stress, and the ability to sustain higher loads without approaching thermal limits. The same result has direct relevance beyond the race track. Data centers, industrial cooling loops, and high-density power electronics face the same physics of high continuous heat loads, limited tolerance for thermal excursions, and growing pressure to extract more performance from existing infrastructure. A coolant that demonstrably increases heat transfer capacity without system modification addresses that problem at its source.
