i also run in buggy 7 port modified or stock ,you have a good point ,in most tracks and in the most races 9901 is aleays the champ ,in the big track that i am racing after 4 years using novarossi pipes and engines ,i am always slower around the track with 9901 ,using 9853 with thin type not the ss always faster but with more spining wheels,when i visit an other tight track 9901 is better,the only thing that makes diference is also that i modify the engines my self and in every day normal race rules are not catching ne here in greece ,yes iam destroing alot of engines but when i success with the mods the pipes are totaly diferent in behaving , we are also testing our stupid modify engines in oval dirt tracks with buggies and trugies ,oval tracks with big straights its a other story ,almost no rules but great great fun,
