GREG South's HQ Holden managed to take out second place in the Street Machine Summernats 30 Horsepower Heroes dyno competition. The car packs a very stout twin-turbo 427-cube LSX motor, and made 755rwhp in qualifying on Saturday.

In the final on Sunday Craig Munro's VX Clubsport was a no show, so that left Greg's HQ to take out second place after registering a respectable 747.9rwhp on the rollers. Jake Edwards's monstrous Torana took out the comp pumping out 1663rwhp.
