Last Truck Race Branch Hatch Circuit. The team manage to get a good setting to have the traction needed to max out engine performance. The 13L Scania XPI Euro 5 based engine is all build with stock engine parts except for the engine management system, turbocharger and wastegate. I’m happy to see we run a very strong engine set-up with a bit more low end power even as most of the competitors in class however there is still work to do on hi end performance as missing half a gear to keep the engine within it’s optimal RPM range from 1000 to 2000Rpm so gear ratios needs to be optimised for this engine.
Are there still option improving on engine performance. Well yes looking at the date from the 13L XPI Euro6 based engine we use on the rally trucks we have better hi end performance due to more efficient engine performance but low end power or toque is reduced to reduce stress on the drive train on these rally trucks as they need to last for many rally Km during rallying. Also for the future we hope to gain even more low end power as the are maxing out the still stock hi pressure fuelpump limiting the amount of fuel en fuel makes torque and power. So in all very happy that we could end last race of this year with an excellent performing engine also hoping to contribute to truck related motorsports as we can build these engine relative low cost as for using stock engine parts with a minimal of modifications needed to get this performance.
