British Superkart Association heads have urged this season’s registered drivers to follow up on its successful test day at Silverstone and help boost entries to the opening rounds of the season. Despite a maximum of 50 drivers taking part in the test day at Silverstone on March 15, only 15 drivers had registered their entry for the opening March 29 event at Oulton Park. Last season’s opening round at Castle Combe attracted 32 drivers. The Silverstone test was the first time the new F250 National class engines were able to be shaken down ahead of Oulton Park. A handful of drivers SUPERKART BOSSES HOPE TEST WILL BOOST ENTRIES were testing the THR and Viper units, but the DEA alternative was unable to be used in its final assembly. New BSA chairman John Dickinson said: “This year with new engines, drivers seem to be being more cautious and are waiting to hear how the units have performed. The test day was more about engine durability than actual performance.” Competition manager Ian Rushforth added: “The new engines are only affecting the sharp end of the grid. We need a minimum of 30 drivers at each round to financially break even and make it viable.”
