In the preceeding week the final modifications were made to the rulebook that will govern the Danish Touringcar Challenge next year. Thus the new rulebook just awaits the final stamp of approval from Dansk Automobil Sports Union which has the sporting authority in Denmark.
The creation of the new rules has been accompanied by discussions and views from the teams and drivers taking part in the series. One of the issues that have been debated has concerned the crankshafts of the series, where some teams have expressed their wishes to make specially-made steel crankshafts legal. However, the organisation behind the Danish Touringcar Challenge has decided to keep the present ruling that only allows the competitor to polish and balance the standard crankshafts.
The biggest change made to the DTC rulebook applies to the means that are used to secure the competitive racing of the series, and this change has won the backing of the majority of teams. The old system of having a weight-to-power ratio of 5,5 kilogrammes per horsepower has been abolished, as it has been difficult to police with accurate measurements involving both scales and rolling road systems. Instead a system of air restrictors have been written into the rulebook.
According to the new rules an air restrictor measuring 50 mm in diameter has to be mounted on engines using standard input manifolds, whereas separate restrictors have to be mounted onto each cylinder if a modified manifold is used. In the latter case a diametre of 32 mm applies to 4 cylinder engines, 29 mm to 5 cylinder engines and 26 mm to 6 cylinder engines.
The first round of the 2001 Danish Touringcar Challenge takes place on Sunday May 6th at the Jyllands-Ring and will be transmitted live by Danish satelite channel TV2 Zulu with edited highlights in the evening on the terrestial channel, TV2.
