Formula Holden star Tim Leahey proved he is as talented as he is unlucky in the latest round of the Australian Driver's Championship at Eastern Creek.

Leahey was fastest in both practice sessions on Friday, set pole position on Saturday and then set and then broke the lap record in both races on Sunday.

However, Leahey departed Eastern Creek without adding to his championship score, but armed with a renewed determination to turn the tables at the next round of the championship at the Clipsal 500 on the street of Adelaide from April 7-9.

Leahey suffered too much wheelspin in the opening race, dropping to fourth place. After breaking the lap record in pursuit of the leaders, Leahey suffered a spin, only to have the car get bogged in a muddy grassed area.

Starting from the rear of the grid in the second race, Leahey again began a dramatic charge, again breaking the lap record as he chased down the leading pack of Christian Muchison, Simon Wills and Matthew Halliday.

Unfortunately, with Leahey piling on the pressure, Halliday spun in front of Leahey, clipping the Murphy Motorsport Reynard 92D of the Melbourne based driver.

As a result of the contact, a damaged suspension arm put Leahey out of the event.

"Our team had the field covered in terms of speed, but I must have run over a black cat," Leahey said.

"The championship is going to be pretty tough now, but we have to put our heads down and concentrate on winning races.

"There are still six rounds to go, so it is still possible to get back in the title chase, but I simply have to go for broke now.

"After being so fast all weekend, to come away with no points is pretty shattering, but you have to take it on the chin and put your head down and keep working.

"It would be more shattering if we were slow and unlucky - at least we have proved we have the speed."
