Turbo timer's !!!!!, do we need them ???? Options

[popstar]

Turbo timer's as i understand are built into an alarm system so you can leave your car still running to let the turbo cool, while you go and watch the game or whatever...................

everyone tells me i should fit one to my '4', i'm thinking that if this is so important, then Mr toyota would have built one in to the cars central locking system, or not let you turn the engin off before the turbo is cool, thus saving the turbo from cracking................

i can't believe that a turboed car needs this unless you've been giving it some really pounding and then just stop it in -20........

so tell me do i need one and if so why ? and why is one not installed as standard if it's important ??????

thanks

Arent a necessity but are a good idea, it allows the turbo and oil to cool through the turbo so that the hot oil doesnt sit and bake in the turbo. I used to sit in my car for a few minutes before i had my timer, it gets annoying.
