A load of motor sport fun with Semi trucks. Last weekend I was over on the Brands Hatch circuit truck racing.

Challenge was to get the Bint race truck with a Detroit 60 series engine fit to perform regarding the ECU setting needed to make more power and less smoke as last year running a modified standard ECU. Think it went well as he now behind Makinen with the Black Sisu truck and second in the championship B division. So I’m happy.

A and B division needs to be explained a bit. A division is manly factory produced or factory supported race trucks and in this class we run the Scania race truck as well as it’s to fast for the B division so you could say the Scania race team is semi professional running a still standard engine. . The Brands Hatch 2017 practice YouTube clearly shows the difference in speed to the B division trucks. As you can see power sliding these 5500Kg trucks no problem keeping the RPM down not to lose traction so it pulls from 1200Rpm almost a flat power curve to 2600Rpm but in order to get max torque @ low end you need some time to build boost and use the turn to do so and shift up from 9t to 10t gear coming out of a slow turn. The rest of the track only done in 10t gear.

The pulling team also tested the Torpedo Scania with the 16.4L engine now modified with Euro5 modified cams and bigger injectors and it looks very promising. Hard to say but for now but we pulled the fastest time of the test day outrunning last years second place winner in the championship with a 18L Volvo engine called the hulk. One of the green white trucks as the other one is called Baby Hulk and look almost identical.
