Reasons Why Your 80 Series Intercooler Is Holding You Back (And What to Do About It)

Image
  If you have a turbodiesel and you find it struggling on hills or overheating when towing, the factory 80-series intercooler could be the culprit, affecting power and fuel efficiency. Be it a Toyota Land Cruiser 80 Series, a Hilux or a Nissan GU Patrol, High Performance Diesel (HPD) has Australian-engineer ed intercooler kits made for your platform, including the 80 Series intercooler. This is what you need to know. Understanding the Function of an Intercooler Your turbocharged engine has an important part called the intercooler. The turbocharger heats the compressed air, which reduces its density and oxygen content. This can have an effect on engine performance, especially during fuel combustion and exhaust gas temperature rise. An intercooler is a heat exchanger that cools the compressed air between the turbocharger and the engine intake, increasing its density and oxygen content, which in turn improves engine efficiency, power, combustion, and fuel economy. Factory intercoolers...

How Can You Verify the Quality of an NP300 Intercooler?

Image
  Did you find a new NP300 intercooler that looks just right and the price also seems fair? But how do you know if it’s worth buying before you spend your money on it? A poor quality intercooler doesn’t always show its problems straight away. It might fit fine, look the part and then underperform when your engine needs it the most. That’s why if you know what to check before you buy the NP300 intercooler saves you from finding out the hard way. This blog walks you through exactly what to look for when verifying the quality of an intercooler. What Makes an NP300 Intercooler “High Quality”? A good intercooler cools efficiently, holds up under pressure and it fits your NP300 without compromise. If any one of these fails then your vehicle’s performance drops. If you tow, carry loads or drive in hot conditions then you want stable intake temperatures and unrestricted airflow. That’s what protects your engine and keeps power delivery smooth instead of consistent. At its core the quality ...

Why Car Enthusiasts Are Upgrading Air Intake Piping in 2026

Image
  Car enthusiasts are always searching for simple upgrades that can make a real difference in how their vehicle performs. In 2026, one upgrade that is gaining a lot of attention is air intake piping. It may not look as exciting as other modifications, but it plays a key role in how your engine works and how your car feels on the road. Understanding the Basics Your car’s engine needs a steady flow of clean air to function properly. The intake system is responsible for delivering that air. When the piping is restrictive or poorly designed, it can limit airflow and reduce engine efficiency. Upgrading the piping helps improve the way air reaches the engine, which can lead to better performance. Many factory-installed systems are designed to be cost-effective rather than performance-focused. That is why car owners are now choosing better quality piping that allows smoother airflow and supports the engine more effectively. Improved Engine Performance One of the main reasons for this gro...

How a Larger GU Patrol Intercooler Drops EGTs and Boosts Towing Torque

Image
  High exhaust gas temperatures are not just a number under the gauge but they’re the indicators that your engine is working harder than it should. And if you’ve ever hauled a heavy trailer up a long climb then you must know exactly what that feeling is when you keep glancing at your temps. If you left these unchecked then they shorten the life of your turbo, your injectors and your motor itself. A larger GU patrol intercooler will not fix a badly tuned engine. But on a GU that is otherwise healthy it is one of the most effective upgrades you can make for heavy or serious towing. Because cooler charge air means the engine does not have to fight itself to make power. Why EGTs Climb Quickly When Towing With a GU Patrol Your vehicle engine operates under sustained load when you hitch up a boat or trailer. And this forces the turbocharger to work harder while compressing air at higher pressures. The Heat Problem Most Patrol Owners Notice First Compression naturally generates heat. As t...

Maintenance Tips to Keep Your Catch Can Working Efficiently

Image
  Why Regular Maintenance Matters An oil catch system plays an important role in keeping harmful oil vapours and contaminants from entering your engine’s intake system. Over time, the collected oil and moisture can build up inside the container. If not cleaned regularly, this buildup can reduce performance and affect engine efficiency. Simple maintenance helps everything run smoothly and supports longer engine life. Check and Empty Frequently One of the most important steps is to check your catch can regularly. How often you empty it depends on your driving habits and engine type. Performance or turbocharged vehicles may require more frequent checks. Make it a habit to inspect the can every few weeks to avoid overflow and pressure issues. Clean the Filter and Hoses Inspect the internal filter and connected hoses for blockages or cracks. Clean the filter if it is reusable, and replace it if needed. Clear hoses ensure proper airflow and prevent leaks that can reduce the effectiveness...

How an Aftermarket GU Patrol Intercooler Levels Up Torque?

Image
  If you drive a GU Patrol, you know it’s a workhorse. It handles long highway hauls, towing, steep climbs, and tough off-road conditions without complaining.  But even these capable vehicles sometimes feel like they’re holding back. You push the accelerator, and the torque doesn’t always hit as sharply as you’d expect. That’s where heat and airflow play a bigger role than most people realise. The stock intercooler does a decent job, but under heavy loads or high temperatures, compressed air from the turbo loses density. Less dense air means less oxygen reaching the engine, which can dull torque output.  This is why an upgraded GU Patrol intercooler isn’t just a number on a spec sheet. It helps your engine deliver power more consistently when you need it most. How Torque Impacts Performance Torque is what gives your Patrol that strong pull, whether you’re climbing steep inclines or towing a trailer. Cooler, denser air from a proper intercooler ensures the cylinders get th...
