Flooding prevention? Engine stays running while key is out of the ignition
So every since day 1, I've let the engine run for 30 seconds before I shut it off and I turn the key to the "on" position and leave it there for 30 seconds before I start it (basically some rotary guys around here said its a way to make sure you don't flood your engine). It seems to be working so far and I feel its a good habit since I do alot of short trips so the engine doesnt always have time to warm up...BUT I'm starting to get tired of doing this and one of the customers at the shop I work at has this system that keeps the engine running for 30 seconds after the key is out of the ignition. He uses it to let his turbos cool down and he hates waiting in his car too. Have any of you guys ever heard of this and where can I find it/whats it called exactly?

apparently it breaks down any carbon built up that can cause harm later. I've been doing that myslef and never flooded mine.

Letting engine run for 30 seconds before shutting it off? what a good way to burn your gas for nothing.
Those are called turbo timer(correct me if wrong) you only need it for older turbos.
totally useless.

in all seriousness, for a normally driven NA street car you will very rarely if ever need to let it sit and cool down.

^^ Ya right......
Turbo timers have there place....if you turn the turbo off hot...the thing will get smoking hot and coke up...you think the engine gets carboned up....you should see a turbo that has been shut down hot consistently...they blow up really fast compared to looking after them and cooling them down properly. Even water cooled turbos are not exempt from this....
Turn an NA car off...unless it's been beaten on at the track.......if it's cold and hasn't warmed up...let it run for a few minutes and give it a bit of a rev before you shut it off....
I run my water pump and the fans for 5+ minutes after a really hot shutdown.....
