He spent five years with Glasgow from 1991 to 1995, slowly improving his average and recorded a 7.43 average in 1993. He was part of the team that won the 'double double' (the 1993 and 1994 league and cup doubles).[5]
In 1996, Glasgow failed to field a team so Powell appeared for the controversial Scottish Monarchs (Edinburgh racing at Glasgow) during the 1996 Premier League speedway season before returning to Glasgow in 1997.[3] It was during 1997 that Powell established himself as one of Glasgow's leading riders and the following season in 1998 averaged an impressive 9.32.[3]
