TANU: Kinnekulle Ring – ROUND 2 | June 9th and 10th
Win and a track record at Kinnekulle
This weekend it was time for round 2 of the TANU series at Kinnekulle ring. The team came in to the round with one goal, to break the track record (currently held by a DTM car). The car was rolled of the trailer Saturday morning and with the new EPAS solution installed as well some replaced parts to fix the boost pressure issue that also haunted the team at round 1 it was now time to see the true potential of the Evo.
However during the Saturdays early practice heats the boost pressure issues from Knutstorp was still there and the boost pressure did not go above 1.1-1.2 bar (should be 2.0) leaving the car with 150-200hp less power. For the 5th and final heat the issue was finally found, however the joy was very short since running at full boost now caused the engine to misfire.
Returning for race day on Sunday we thought the problem with misfires was resolved after we found that the connection between the ignition coils and ignition cables was not perfect. However during the warm-up this was found not to be the case. To make matters worse the car now did not run on low boost either. So before Q1 more or less all cables and parts around the ignition system was replaced as well as the spark plugs and injectors. However the car still suffered badly from misfires as soon as the boost pressure increased. The team figured out it was bad sparks causing the misfire and with no real fix available a last shot was to decrease the spark plug gaps to improve the sparks slightly. Although not solving the issue it made it good enough to run low boost settings at 1.1-1.2 bar boost pressure.
Now being into Q2 we went out on the track and started to step up the pace, after only 2 laps on attack we got a technical flag due to sound levels being over the regulation 95dB and we had to abort Q2.
So for the final an extra silencer was fitted and we headed out again, although running on low boost the record was still within reach and on the first full attack lap a time of 49.768 was put down beating the old record with 0,15 sec and winning the round.
The team now has 3 weeks to solve the engine issues as well as implementing some other small improvements for round 3 on Mantorp Park. .
Also big thanks to everyone joining up and helping out during the weekend, without you we wouldn’t have made it this time.
Now it’s time to go brake some more records….
