The recipe for that thing is well known - very rich AFR and very retarded ignition timing. Something like 9.5-10 AFR and -10-30 degrees of ignition timing depending on a particular engine. However, if the car is turbocharged I would strongly recommend avoid doing it unless you have a budget to change turbos more often than normally required... Those little bangs near by the turbo don't help it to last long enough...
In Aussie, you'll also attract the attention of the Cops, so if you aren't 100% legal, at least visually, you may be better of being discreet.
