Proper idle cool-down without pyro
I haven't yet put in a Banks kit on my truck. I have a '97 F-250 w/ a Pinnacle 4" stainless exhaust. I'm not sure if the previous owner chipped the truck via the OBDII port but this truck sure does seem to launch up and away when that boost builds, and the exhaust note is rather exquisite (more of a primal growl).
Seeing that I shut my truck down about 6-10 times a day while out on my route, I am concerned about shutting the motor (and oil pressure) off on a hot turbo. My buddy who has an '01 with the Banks kit just waits for the pyro guage to drop down to 200-300 before shutting off. Without knowing my EGT or my oil temp coming out of the turbo loop, when I arrive at a destination, what would be a good amount to let the truck idle before shutting it off? 30 sec, 60 sec, 2 min, 5 min?
I remember my cousin who drove a souped up Mitsubishi Eclipse had a turbo timer installed on her car. She would put it in neutral, apply the parking brake, and turn the key off and pull it out and the engine would continue to run until an oil temp sensor read a certain temperature.
What do y'all do to avoid premature frying of that air squasher in your truck?
