It's all done with a stealth approach that results in a fundamentally OE (original equipment) look under the bonnet, but it's anything but OE on the road. Try 330kW with full boost of 10 - 11psi tapering off to between 9 - 10. You've just obliterated every performance Ute on the showroom floor and we've only just started.

This takes the car as far it can go within the performance of the standard intercooler. To go beyond 330kW and onto the next level requires significant intercooling with an additional group of components. Welcome to Phase III and fun city.

First the area was measured to fit the biggest intercooler possible in the space available, all without butchering the front end and needing a sledgehammer to install it. Right now, the best intercoolers are built overseas, so a core was custom made to APS specifications that can cope with a genuine 600hp.

Now intercooling is a compromise, it's all about charge air temperature reduction versus pressure drop reduction. Luxon says the APS intercooler is the best heat exchanger intercooler technology available on the planet and what Porsche would use.

Another limitation was the airflow, so a relocation kit is used to swap the battery and air cleaner. A complete new air cleaner package is fitted behind the right headlight, which provides a short route to the turbo and allows the XR6 to swallow a lot more air.
