• Air filter element – From our testing there is no gain in performance by replacing the standard Nissan air box as it does not pose a restriction even in supercharged applications. Additionally, an aftermarket air box may also mess with the laminar flow of the air through the air flow meter which can cause tuning / driveability issues. We use a high flow serviceable air filter like a BMC or K&N filter to minimise filter restriction and it has the ability to be cleaned and reused almost indefinitely.
• Dyno Tuning (Y62) – By optimizing the engine tune parameters in the vehicles PCM (Powertrain Control Module) to suit 98 octane fuel, we are able to increase both power and torque and maximise fuel economy however it’s worth noting that late model naturally aspirated cars are generally tuned very well from the manufacturer so depending on the vehicle platform mechanical parts to improve the engines intake & exhaust flow may need to be added to really get good gains. In its simplest form, to make more power by tuning any petrol engine we need to add ignition timing and optimise the air / fuel ratio (AFR). The PCM in the current Patrol is super smart and is constantly trying to add ignition timing to maximise engine efficiency. The PCM relies on knock sensors to determine how much timing it can add, it can also determine the quality of fuel and will adjust ignition timing automatically and seamlessly so running a chip device as an alternative to proper PCM tuning with so called selectable 98, 95, or 91 octane tunes is redundant as the factory PCM can already alter its tuning parameters for differing fuel octanes. It’s been widely rumoured that the air / fuel ratio at wide open throttle (WOT) in the Y62 Patrol is rich but its relevance has been larger overstated as this only happens above 130kph in attempt to protect the catalytic converters during sustained high-power requirements, we do not alter this unless aftermarket headers and cats are installed.
• Catback Exhaust system – A ‘Catback’ system is basically all the parts of the exhaust after the catalytic converters. It’s the section of exhaust where all the mufflers are placed and by using larger diameter pipe and high flowing mufflers more performance and better sound is achieved. HPF works closely with our 2 major exhaust suppliers Pacemaker and Manta but for the Y62 we use Hurricane Headers out of Moorebank NSW as they build a single 3.5” system which is unique to the Y62 market. Hurricane Headers are Australian made and owned and have been since their inception over 45 years ago.
