Lowered turbo boost for Volkswagen

The turbo boost for the bio gas (CNG) powered Volkswagen Scirocco in the Swedish Touring Car Championship has been lowered by 0.05 bar.
“We are monitoring the performance of the cars via data logging. We felt after the race at Karlskoga that we had to do something, the tendency was that the bio gas cars were too quick in a straight line,” said Johnny Haraldsson, technical director of STCC AB.

The boost has been changed to 2.20 bar, with an air restrictor of 38 mm, from the previous 2.25 bar of the turbo charged Volkswagen engine.

“We have lowered the boost with 0.05 bar and it is on the same level as in 2009,” said Haraldsson.

Volkswagen team boss Tommy Kristoffersson says that it is wrong to reduce the boost with the performance of their cars during the race at Karlskoga as base.

“We at Team Biogas do of course think it hits us a bit wrong, Karlskoga is a track that suits our cars perfectly and they were at the same time 60 kilos lighter compared to the other cars,” said Kristoffersson.

The Volkswagen cars has received maximum penalty weight for the race at Jyllandsringen this weekend as it is the first time the newly homologated S2000 specification Sciroccos takes part in the Scandinavian Cup.

“The new conditions are of course make things hard for us at Jyllandsringen. But if we are to look at it from the bright side, this is a receipt that we have made it, that we already have come this far with a new type of fuel that they have to reduce our performance. That is a victory it self,” said Kristoffersson.

STCC AB has received a lot of criticism lately for the differences between the cars in the S2000 regulations. Technical director Haraldsson says that they are longing for the S2000 regulations to be gone.

“We are looking forward to get rid of all this with weights and performance in the future. It takes too much energy to deal with this. The teams of WTCC are putting more energy on politics than to make the cars go faster. I am not saying that this is the case in Sweden, but it is going to be nice to get rid of the politics in the future,” said Haraldsson.

STCC AB are yet to announce the regulations that are going to replace the current S2000 regulations. Information to TouringCarTimes.com suggests that the NGTC (BTCC) regulations and the BTCS regulations are on top of the list currently.
