So we done a long a long race weekend on Truck-Grand-Prix Nurburgring getting a load of data from the data logging systems.
Been there supporting A level Race engines used for Fia and A division trucks UK truck racing. In short the engine spec, able to make 1100Hp and around 6000Nm of torque with a max engine displacement of 13L. FIA championship runs 63mm inlet restriction so these will be just over 1000Hp due to this but max torque will be the same so power difference is in top end performance running a inlet restriction.
Engines run around 3Bar boost pressure, no smoke and power comes on @ 1000Rpm and boost so power will come on gently while coming out of a corner on the race track. If max power can be used communing out of a corner upfront taking the corner breaking and applying power to the engine is used to build boost pressure and timing on when to let go of the breaks and apply full power is essential even @ 100Kmh your able to power slide the truck easy. For the most part only last gear is used, only on the slower speed corners a downshift is used mainly to spool the turbo a bit more off power and get some more cornering stability as the backend of the truck pulls you in getter in to the corner so you can call this engine breaking. Out of the corner most will do a up shift as very soon you will lose traction running second hi gear as your hitting 1000Hp with the massive torque out of these engines.
So next ongoing is to write new software optimising torque control and we not yet on the max on fuel on these engines but we know soon we run out of fuel coming up with a bigger commonrail fuelpump.

To get an impression on what European truck racing is like.
