Part 3: TopGear edition

Today we arrive at a tiny disused racetrack outside the village of Old Beach, somewhere in Australia. The mission? To get a lap time of 70 seconds in a car worth £1200.

One lap of the track is 1.24 miles, so to do it in 70 seconds you would need an average speed of say... 64 miles per hour. But obviously you need to go much faster than that, as you have to slow down for the corners.

In Brittan, we had the Vauxhall Carlton. In 1986, Holden shoved a Nissan Skyline motor in it and called it the Commodore. And quite cheap these days. This one was picked up for £970 on ebay.

Some say, he has a full set of car parts in his bedroom... bla bla bla...

The first recorded lap is 74 seconds, but some smoke is seen to rise from the S bend in the track. Oh dear. Dave the caretaker is coming over in his little truck, this can't be good.

Aarons turbo charged Corolla Levin on race tyres.

With a bit more care taken not to drift this time, we went out again. The clutch slipped and the rear tyres spun but the lap times came down, then a 70 second lap time!
