Video: Watch On Board as a C4 Corvette Takes On a Narrow Hill-Climb
Since 1952, cars have been tearing up the Collingrove Hillclimb near Adelaide, Australia. Originally laid out by Harold Clisby and Bob Angus in 1950 using a Jeep with a grader, and following the contours of Angaston Hill, the course features very steep sections and even a short downhill.
The first public event drew a reported 6,500 spectators, and today, the narrow, challenging course hosts dozens of events each year, including “Come & Try” days when the general public is invited to take a run at the hill for minimal expense.
The track is just 700 meters long, with 6 turns, and the current record is well under 30 seconds for open wheel “formula” type cars. Barely wide enough for a single car, the Collingrove course is an exercise in precision, rather than brute force.
In this video, we ride along with Sean Hayter in his 1985 Corvette, which is a right-hand-drive conversion for the Australian market. His best run of the day was 38 seconds flat. According to the video poster, the Corvette is powered by a 5.7l (350 CI) small block Chevy with CNC Edelbrock heads, flat-top pistons producing a 10:1 compression ratio, a Lunati cam, and an SLP injection system.
Like the CDS Farms & Motorsports Park video we brought you previously, the Collingrove course looks to be very technical, unforgiving of a wheel misplaced, but a hell of a lot of fun…
