Some years back there was a lot of talk about turbo timers to prevent turbo bearing cokeing but, for whatever reason, no one seems to know what I'm talking about. Maybe because some of the new fueling boxes have this feature built in them. What I want to do is build my own relay timer so that I can run an auxiliary 12 volt fan for about 30 minutes or less after engine shut down but I cant seem to find any kind of timer relay that can do this. There used to be aftermarket turbo timers which would run the truck for 5 minutes or so after turning the key OFF, unless you opted to override the timer with a button. Maybe there aren’t too many guys who have been on these forums for 10 years so and have no recollection of anything like I'm after. There seems to be some 2nd gen Cummins gadgets no one talks about anymore, like there was a turbo protector which used a thermocouple or tied into an existing thermocouple, and shut the engine down when the turbo reached a set EGT after the key was shut OFF….. but this isnt what I’m talking about.If anyone has idea where to get what I’m after or knows where I can purchase the stuff to put together what I’m trying to do. Thanks.
