Viper,
I normally dont bite on threads like this, but I get the sneaky suspicion the rule was made specifically for young drivers such as yourself.
Do yourself a favour, spend some time in a NA car, learn to drive it properly, come on a few track days that are listed in the Events thread, and by the time you come off your P's not only will it be legal for you to drive a boosted car but you might have actually learnt how to use it, these skills cost lives if attempted on the streets.
Im keen to take it up a notch, for public safety I would personally like to offer YOU! a $50 discount at the next drive day so you can learn what its really about. When you pick a date that suits PM me and I will help fund your first drive day.
Remember I have been 18 year’s old for the last 18 years, so I do have some idea what Im talking about.
Hope to see you at the track soon.
