Last two days last testing of the Rally Truck.

An almost endless list of things to test from changing a tyre under 7 min to handling the tyre pressure system getting stuck in the mud and able to get the truck out by deflating the tyres.
Same thing for the engine getting the feeling what it can handle with more (low end) torque able to step op a gear gain more speed riding the sand dunes.

Biggest chance to the engine are the pitons. Still all steel but these are better to handle the heat transfer from the piston dome. Other big chance is the way we control the fuelpump pressure and dialling this in is a load of work as there are big changes on how fuel pressure reacts on load and rail pressure variations.
