The Bathurst 1000 has welcomed its fair share of underdog results, but none more popular than 1990.
Turbos were dominating the Australian Touring Car Championship at the time, particularly the Ford Sierra RS500 Cosworth and the Nissan Skyline HR31 GTS-R.
However, there was more on the horizon for Nissan as the R32 GT-R debuted during the season previewing the Godzilla’s capabilities.
But at Bathurst, nothing was guaranteed and this was proven none more so than in 1990.
Holden hadn’t won an ATCC round since 1986 and the VL Group A SV was out of its depth compared to the turbo wars occurring at the front.
Although its sprint credentials weren’t strong, the Holden came into its own during endurance season.
The Holden Racing Team was formed in 1990 and Win Percy was placed at the helm by long-time friend Tom Walkinshaw.
Percy recruited great personnel including engineer Wally Storey for the assault on the ATCC and end of year endurance events.
Rebuilding one of the Commodore VL Group A SS from the failed 1988 campaign, particularly the chassis to suffer failed suspension.
New Dunlop tyres mated with carbon-metallic brake pads and AP Racing calipers gave the team an advantage at the Mountain.
Percy recruited, against Walkinshaw’s wishes, Allan Grice to co-drive at Bathurst and the decision was soon to be vindicated.
Recovering from a shoulder injury, Percy had Grice complete most of the race and the duo outlasted their turbo competitors to take a famous win.
The GT-R retired, many RS500s joined it and the mighty Commodore greeted the chequered flag.
Considering the same Commodore had lasted barely 20 laps in 1988, it was a great resurrection.
