Not happy with the factory stock 6.2-liter LS3 under the hood of his daily driver HSV Clubsport, Gup replaced it with a 727-cubic-inch V8 (do the math – its displacement is more than 11.9-liters!) from Sonny's Racing Components. The $55,900 crate engine makes a whopping 1,275 horsepower on standard 91 octane pump gas, thanks in part to a massive 3,500-cfm throttle body perched on top. Custom-mounted in the nose of his Holden, Gup chose to send all of the power rearward through a two-speed Powerglide automatic transmission working through a nine-inch differential. The numbers speak for themselves – late last year, the car ran the quarter in 10.5 at 140 miles per hour.
But all good things, including this right-hand-drive Holden, will eventually come to an end. We don't know exactly what gave out during the demonstration at Powercruise USA held at Brainerd International Raceway in Minnesota this past weekend, but it sure expired in spectacular fashion. See for yourself below.
