Thomson, the points race champion at Kuala Lumpur in 1998, manages the Invercargill branch of Cycle Surgery in Invercargill.
Scully (19), one of the bright hopes of New Zealand cycling, has competed at two junior world championships and was in the New Zealand senior team's pursuit combination that came fourth in a World Cup event at Melbourne last year.
"We always talk about cycling in the shop," Scully said. "Glen has given me a few tips and I've learnt quite a bit from him."
Scully put this information to good use when he won the keirin in convincing fashion at the New Zealand Cup on Wheels at the Mosgiel velodrome on Saturday.
He blew the field apart when he got up on his toes and sprinted one-and-a-half laps from home.
The pack was waiting for someone to jump out after the bell, but Scully caught them by surprise by going early. Matthew Vermunt (Southland) and Daniel Beatson (Otago) were left to fight for the minor placings.
Scully also finished third in the 2000m scratch race and the 80 lap points race behind the Timaru pair of Olympian Marc Ryan and Shane Archibald.
Archibald (19), a fulltime cyclist, showed why he is a member of the Bike New Zealand High Performance team.
He came second to Ryan in three events on Saturday - the scratch race, the New Zealand Cup on Wheels and the points race.
In the scratch race he led for the last two laps and was beaten by Ryan when he came screaming past in the straight.
In the New Zealand Cup on Wheels he was on scratch with Ryan and clung to the Olympian's wheels when he led over the final three laps.
He teamed brilliantly with Ryan in the points race and got a jump on the field when he gained two laps and helped the Olympian to get a four-lap lead on the field.
Ryan won the points race with 103 points, followed home by Archibald 64 and Scully 20.
Otago's Charlotte Kelly (16), who returned home this week after winning a bronze medal in the 7.5km scratch race at the Australian Youth Olympics in Sydney, was the best performed female rider on the track.
She won the 2000m scratch from fellow Dunedin cyclists Honor Davies and Katri Laike.
In the women's keirin, Kelly had to use all her strength to catch Davies, who led into the straight and was only passed in the last 10m. The last 200m was timed at 13.92sec.
Patrick Jones (Otago), a pupil at Taieri College, was the best performed junior and won the 1000m scratch race from Ashley Stanley (Otago) by snatching the lead from Blair King (Otago) at the bell.
In the 40 lap points race Jones (15) won comfortably from Fred Brookes (Otago).
Regan King (15), another Taieri College pupil, started with a handicap of 50m and used this advantage effectively to win the Junior New Zealand Cup on Wheels
