One of my favourite events that I am involved with is the World Time Attack Challenge (WTAC), which is held every September/ October at Eastern Creek Raceway, now called Sydney Motorsport Park.
Yes, the cars in the Open class and above look like the love child of the Batmobile and Keith Richards, and yes, most of the car prep is a bit casual, to put it politely, but it is a technically open event and, as such, makes a refreshing change from the dead end of spec formula and tight formula regulations that most motorsport regulators today seem to think is a good idea.
For this year’s event, I was race engineering the Tanuki S-13 Tilt in the Pro/ Pro Am class. This car started life as the MCA Hammerhead but changed hands and went through a considerable mid-life upgrade. We are now talking 1000bhp and more downforce than an LMP2 car. This is the car shown in the opening image.
The other thing that makes this category unusual is that it’s an open tyre formula, and this year allowed slick tyres for the first time.
