Few things come close to the thrill of pushing a high-performance car to the limit on a track day. The roaring engine, the adrenaline surge of speed, the powerful thrum of the powertrain hard at work – it’s an experience like no other. However, high-performance cars like the Nissan Skyline GT-R put enormous strain on their engines during track days, resulting in excess heat that can severely impact performance and potentially cause damage. This article will delve into various methods you can employ to manage and reduce engine heat in your Nissan Skyline GT-R on track days effectively.
1. Importance of Using High-Quality Oil
The first line of defense against high engine temperatures is using high-quality oil. Oil acts as a coolant as well as a lubricant in your engine, reducing friction between moving parts and preventing overheating. Besides, high-quality oils have better heat resistance and will not break down easily even under the immense stress of a track day.

Synthetic oils are an excellent choice for high-performance cars like the Nissan Skyline GT-R. They have been engineered to provide superior performance under extreme conditions. While they might be more expensive than conventional oils, their ability to protect your engine from the harmful effects of high temperatures is unparalleled.

2. Cooling Systems: Radiator and Intercooler Upgrades
Proper cooling systems are essential for maintaining optimal engine temperatures during high-speed driving. Upgrading your radiator and intercooler can significantly improve your car’s ability to cool down the engine.

A larger or performance-oriented radiator can provide a greater surface area for heat dissipation, effectively reducing the temperature of the coolant before it returns to the engine. On the other hand, an upgraded intercooler can better cool the charged air from the turbo before it enters the engine, thereby reducing the overall engine heat.
It’s important to note, though, that these upgrades should be done by professionals to ensure proper fitting and maximum efficiency.
3. Enhancing Air Flow with Performance Air Intakes
Air flow is crucial in regulating engine temperature. A performance air intake system can drastically improve the amount of cool air flowing into the engine, thereby helping to reduce heat production. This is especially useful for turbocharged cars like the Nissan Skyline GT-R, where the turbocharger can generate significant amounts of heat.
Performance air intakes are designed to draw in more air than the factory stock intake, with the added benefit of it being cooler. Cooler air entering the engine lowers the engine’s operating temperature and increases the power output.
4. Brake Cooling: Ventilation and High-Temperature Brake Fluid
While engine heat is a primary concern, brake heat is also worth considering. High-speed track driving puts a lot of stress on the brakes, causing them to heat up quickly. Excessive brake heat can lead to decreased braking performance or even failure.
To combat this, consider installing brake cooling ducts that direct airflow to the brakes, helping to keep them cool. Additionally, using high-temperature brake fluid can resist the heat generated during heavy braking, maintaining optimal braking performance.
5. Performance Exhaust Systems
Lastly, a performance exhaust system can be a significant help in reducing engine heat. By expelling exhaust gases more efficiently than a stock system, it helps to lower the engine’s operating temperature.
In the case of the Nissan Skyline GT-R, a larger diameter exhaust pipe will allow gases to exit more quickly, helping to reduce stress on the engine. Additionally, a performance exhaust system can also lead to a slight increase in power, which can be another advantage on track days.
To sum up, reducing engine heat in a high-performance car like the Nissan Skyline GT-R involves a combination of using high-quality oil, upgrading the cooling and exhaust systems, enhancing air flow, and ensuring adequate brake cooling. These methods will not only protect your car from potential overheating damage but also optimize its performance for an exhilarating track day experience.
6. Installing an Oil Cooler
A crucial method to consider in controlling engine heat is the installation of an oil cooler. An oil cooler works by cooling the engine oil as it passes through the cooler before returning to the engine. This helps in maintaining the optimal temperature of the engine oil, which in turn keeps the engine temperature in check.
The Nissan Skyline GT-R, equipped with a powerful RB26DETT engine, produces immense heat, especially during a track day. As such, an oil cooler is instrumental in ensuring the engine’s heat is effectively managed. Remember, the cooler the oil, the better it can perform its job of reducing friction and potential wear on moving parts.
Bear in mind that an oil cooler installation is a delicate process which requires professional handling. You wouldn’t want potential leaks or an improperly fitted cooler, which could do more harm than good.
7. Optimizing Your Vehicle’s Wheel Drive System
The Nissan Skyline GT-R, with its advanced All-Wheel Drive (AWD) system, also known as the ATTESA E-TS, has the power distributed to all four wheels. Maximizing the efficiency of this wheel drive system can play a significant role in reducing engine heat.
Ensuring the system is properly balanced reduces strain on the engine, thereby reducing heat. Regular maintenance of the AWD system is, therefore, paramount. This includes checking the transfer case and differentials for any signs of wear or damage, and ensuring the front and rear wheels’ alignment is perfect.
Moreover, the weight distribution between the front rear, affects the drive system’s efficiency. Adding or reducing weight can influence the drive system, affecting the strain on the engine and consequently its heat production.
Conclusion
Protection against engine heat is essential for any high-performance car, especially on a track day. For the Nissan Skyline GT-R, this is no exception. Whether it’s the use of high-quality engine oil, upgrading the cooling systems, enhancing air flow, brake cooling, installing a performance exhaust system, adding an oil cooler, or optimizing the wheel drive system, every step is crucial in achieving optimal engine temperature.
In conclusion, taking the necessary measures to effectively handle engine heat is not just about maintaining your car’s top speed or improving lap times. It’s about preserving the engine’s condition, thereby extending its lifespan. It’s about getting the best out of your Nissan Skyline GT-R, whether you’re on the track or the open road, for an unforgettable driving experience.
