TANU: Kinnekulle Ring – ROUND 3 | June 29th and 30th

The Big Lap Record!

This weekend it was time for round 3 of TANU this time at the most legendary track in Scandinavia, Mantorp Park.

The team headed up to the track early on Friday morning after working late on Thursday to get the car ready (late arrival of parts for the new silencer setup). Having found and fixed the boost/missfire issue from Rd2 the team had big hopes for the weekend. Going out in practice session 1 the car felt good and the engine was running very nicely at full boost with no issues at all. However the joy was short as on the 3rd lap at full boost in 5th gear there was a huge boom noise and the engine lost all power. Coming into the pits it was found out that it was not to bad as it was only the pressure hose from the outlet of the turbo that had simply burst under the boost pressure. A new pressure hose was fitted and the team headed out for practice 3. However during the first full throttle run on the straight the same boom and boost pressure was gone again. This time however the hose hadn´t burst but simply slid of the pipe. The problem with the spare hose was that it was slightly shorter then the original hose that was secured by double clamps at each end. However this was not possible with the shorter hose. The team tried some different solution to fix it for practice 4 but to no affect so it was simply to pack it up for the day. Meanwhile in our hometown Street Performance had already prepared and delivered a big box of all different kind of premium pressure hoses from their shop for the team to bring with us on Saturday morning.

Saturday – Race day
With new (better) hoses fitted and secured the team headed out for the warmup, Unfortunately one of the Pro cars in the heat before had a engine failure and poured out oil on the track. The Xtreme Rescue Team that TANU uses during their events did a great and quick job (as usual) to fix the track but unfortunately the delay meant only 1 warmup lap could be done. At least it was enough to see that the hoses stayed on at full boost.
Now it was time for Q1.

Coming out to Q1 not a single complete lap had been run at full attack but fearing that more issues could occur there was no gambling and a fast lap was to be put down directly. Two warmup laps where done and then the first attack lap was started. The car felt amazing and coming over the finish line the dash showed the time 1.14.49 beating the old track record of 1.14,6. A second lap was started but in the second corner however the next issue arrived as the brake fluid boiled and all brake performance was gone. It was simply the fact that at the fast Mantorp and running at the higher power the front discs was simply to small to handle the engery put in and thus boiling the brake fluid (to much weight savings). The entire team was quite shocked that the (supposedly hardest to beat) record had been broken on the first attack lap. It was now time to crush it….

The car was pitted and prepared for Q2. Knowing we only had 1 lap to put in a good time the tire pressures was adjusted accordingly. However the troubles was not over as during the warmup lap something in the front suspension broke in a right hand corner. After coming back into the pit it was found out that the wheel bearing hub had split into two. The team went to work to get the car ready for the Final and it was rolled out of the garage just 5 min before the closing of check in.
Winning the race was ofcourse of big importance so to not risk it the brakes was not used at all during the warmup lap thus having cold tires starting the attack lap (impossible to get enough heat in the front racing slicks without braking). It was a full attack lap and coming up on half lap distance the time was almost exactly the same as the record lap from Q1. During the second half of the lap the tire temp came up and the lap could be finished of almost 1 second quicker meaning a new lap record of 1.13.525 destroying the old record. The second lap was started but in the last corner before the long straight the brake fluid boiled again and the lap had to be aborted. The time up on the previous lap in the first sector? A whopping 0.8 seconds.

The team is super happy with another win and to crush the overall tintop track record. Regards to the what could of been lap, don´t worry in 5 weeks time it´s time for the biggest event of the year at TANUs time attack festival at, you guessed it Mantorp Park.

So if you want to see a new track record be sure to save the date, also the rumors says an update package is being fitted for the time attack festival. Don´t miss it!

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….
