HP DIESEL FOR TOYOTA 300 SERIES LANDCRUISER
High Performance Diesel has developed a ‘holy trinity’ of products for this vehicle
Following extensive research and development work with Brad Schumacher’s 300 Series Landcruiser, High Performance Diesel (HPD) has developed what it describes as its “holy trinity” of products for this popular vehicle: the much-anticipated Heat Exchanger kit, Transcooler kit, and Catch Can kit.
The Heat Exchanger Kit
Like many 300 Series Landcruiser owners, HPD says Brad had reported severe power loss (commonly called derating) during towing.
As intake temperatures heated up during uphill towing tests, HPD reports it experienced noticeable power loss, as the engine management system was doing its job protecting the engine.
In dyno conditions, HPD reports the power loss was much worse. With a maximum figure of 140kW at the wheels, its team observed power figures as low as 25 kW after only four minutes, holding sustained load simulating extreme towing conditions.
HPD explains Toyota’s latest generation of Diesel passenger vehicles now have water-to-air intercoolers (W/A), as they can be packaged much smaller than the previous generation’s air-to-air intercoolers (A/A) and in normal conditions, provide similar charge air cooling performance.
HPD says the problem is, on the 300 Series, the little radiators (heat exchangers) in the front bumper that cool down the coolant circulating through the W/A intercooler don’t receive good airflow.
Under extreme load the OEM heat exchangers can’t reduce the coolant temperature adequately and suffer from heat soak.
To help maintain maximum performance when the heat is on, HPD states it has developed a solution that does not require any cutting or drilling and only takes around an hour to install: HPD’s HEK-300-F-A heat exchanger unit.
HPD explains this is a high quality, Australian made auxiliary heat exchanger that is mounted into direct air flow behind the grille, maintaining much lower coolant temps entering the W/A intercooler.
HPD states it features “all the tried and proven elements that have made HPD products famous,” including Bar and Plate core and CNC machined billet end tanks with minimum 3mm wall thickness.
And like all HPD products, it comes with every nut, bolt, bracket and hose for a perfect, factory-look installation.
During rigorous dyno testing once the unit was fitted, HPD reports it did not record power figures lower than 123 kW despite long sustained pulls replicating extreme towing conditions as well as multiple back-to-back power runs.
During road testing, towing a 2.2 tonne load, the team states it did not experience any noticeable power loss.
Better still, HPD says that Brad, the owner of the vehicle, reported that during his subsequent family trip, towing his 3.5 tonne caravan up Accommodation Hill, “the vehicle didn’t even think about losing power.”
The rest of the “holy trinity”
HPD also developed a transmission cooler kit that reduces transmission temps by 15°C for additional transmission protection.
It further states that the famous HPD Catch Can also fitted has a beautiful and durable billet intake adapter that ensures all the hoses in the PCV system are neatly integrated with the catch can kit to create a factory look installation and ensure there are no low spots for oil vapour to condense into pools of oil, thereby increasing crankcase pressure.
Orders available now
Transcooler and Catch Can kits are readily available, but due to demand for the Heat Exchanger kits, HPD states there is an approximate six week wait for delivery, so it advises orders are placed as soon as possible to ensure the shortest wait time possible.
