Dale Heiler had the Castle Hill Performance Twin Turbo VT Commodore on show at Summernats 32 to take on the AC Delco Door Slammer in a battle between Supercharger v Turbo for bragging rights. After 3 days of side-by-side Dyno runs the Twin Turbo VT took the win. These dyno runs were for demonstration purposes only and weren’t part of the Summernats Dyno competition.
The Haltech EFI-controlled 540ci twin-turbo big-block running 54 pound of boost laid down the highest horsepower figure ever seen at Summernats with an eye watering 3,076rwhp pass, backed up with a 3,065hp run on Sunday afternoon.
