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

my car is n/a and i have one! i belive it's very importand to let your car coulldown for atleast a minuite. it's too brutal to turn your car off the minuite you stop especialy when your hard-drive it!!!! you should give your car some time to let your oils water temp turbo etc to coolldown! for me the timer is an necessary item, that's my idea about them....

Its even more brutal to take your car for a hard drive then let it sit getting hotter.
Having a turbo timer on a N/A car is worse than a total waste of time and is probably doing more harm than good. Having a car stationary is not going to let anything cool down on a N/A car, its just gonna get hotter and hotter without the cooling airflow moving over the radiator, oil cooler etc. Turbo timers do nothing to let the engine cool down, or it would be called an engine timer. thier purpose is to let the turbo cool after a hard drive, the reasons are explained above.
