Triple Eight reveals sound of V6 turbo

Triple Eight has given a preview of what its V6 turbo Supercar will sound like when it hits the grid next year.

The team has released a brief video clip of Craig Lowndes driving the Holden 'Sandman' that is being used as a test mule for the project.

Watch the video below featuring the 3.6 litre V6 twin-turbo lapping the Norwell Motorplex.

The engine has now completed 550km at Norwell with two more days of running undertaken this week.

The latest testing featured Shane van Gisbergem, who was away racing in the United States when the first runs were completed.

Testing has included running various iterations of exhausts as the team attempts to create the best sound possible from the engine. 

While it was immediately evident when testing began that outright volume would not be an issue, the efforts have gone into refining the noise.

Triple Eight owner Roland Dane recently spoke bullishly about how fans will react to the sound of the first non-V8 engine in the category in 25 years.

"If you had 26 of those on the grid - not necessarily all Holden engines, but a mixture of V6 turbos - you won't miss a V8 for a second, I promise you," he told Fox Sports in Townsville.

“And the hissing and wheezing and banging in the corners is great.”

The main focus of the testing has, meanwhile, been cooling and driveability, with Lowndes, Jamie Whincup, Steven Richards and now van Gisbergen all providing feedback.

Triple Eight and Holden recently announced plans to debut the engine in selected wildcard races next year, continuing with the V8 for its full-season entries.

It's a busy week for Triple Eight, with the two days at Norwell coming prior to a test at Queensland Raceway on Friday where it will run three Super2 drivers in a current generation car.
