I know this may be a little off topic but im not sure whre else to post this. does anybody know where i can purchase a autoshut off timer switch? Or if they even exist. I want a setup kind of likea turbo timer on a turbo car only instead of having my entire engine running i want it to tun my electric waterpump and both fans for about ten minutes after i shut the car off. this is for when i go to the drag strip so it has plenty of time to cool down really quick between runs. It would also be nice if it had a manual overide so i could leave it on as long as i want. I dont wan tto go with an actual turbo timer cause they hook up to the ignition and i dont want my whole motor running. can anyone help me out?

I've thought about this myself. I think setting the bypass switch to send power to a thermostat in the radiator (similar to the ones used for aftermarket cooling fans) and then to the relays for water pump and fan would be the way to go. 3 way switch, pos1 off (power feed from ECU and ignition switch), pos2 on (feed power to relays directly), pos 3 (feed power to thermostat then to relays).
Sounds complicated, but much easier than a timer circuit.
