Proctor rates both Smith and fellow series regular and two-time MSC champ Steve Ross (McRae GM1) from Dunedin as likely threats this and next weekend, though with 27-strong grids for the MSC races he says there could be 'six or seven other guys' in the leading bunch.
Proctor and Kiwi racing great Ken Smith (Lola T332 #11, above) are expected to set the pace in the MSC series races at the meeting.
Ken Smith, meanwhile, is looking forward to his first races back in his ex-Danny Ongais Lola T332, after the engine damage sustained at the first NZ Festival round last year ended his 13/14 MSC season early.
Having missed the first two rounds of this season's MSC series across the Tasman, another series title is a long-shot for the 73-year-old, in his 57th consecutive year of national level single-seater racing. But pole positions, race wins and lap records are there for the taking - particularly at Hampton Downs.
Lyons is the current F5000 - and outright - lap record holder at Hampton Downs thanks to the 59.483s time he set in the second race at the second NZ Festival meeting last year. But before his car's engine blew at the first round Smith claimed pole position with a time of 59.445.
Only times set in a race can be classed as lap record but the qualifying time certainly shows what Smith and the T332 Lola are capable of this and next weekend.
MSC series regulars from this side of the Tasman will be joined this weekend and next by Australian series front-runners Paul Zazryn (Lola T332) and Paul Brennan (Lola T330). And debuting long-awaited new cars will be the two men behind the Hampton Downs development, Tony Roberts and Chris Watson.
This time Roberts will be behind the wheel of a McLaren M10B, Watson a Gardos, the latter a McLaren M18-based car built in 1973 in Australia.
Finally, as well as the 26 F5000 cars entered for the three MSC series races each weekend (2 x 8-lap & 1 x 15 lap) British driver Robs Lamplough will drive the V12-engined ex Howden Ganley BRM P180-02 Formula 1 car and there will be as many as 20 other Formula 5000 cars at the track being demonstrated or on display.
