I have a TT from an old project I never used, and I don't plan to run it on the FD, but is there A way I can utilize the timer function to run the rad fans for a programmed time after shutdown? Has anyone done this and if so help a brother out with wiring tips -



Should I run a whole new relay/powersource to the fans and just bypass the stock setup "overriding" it by supplying power from the tt?? It seems all i need is the turbo timer to get the "power off" signal on the correct wire upon shutdown to activate its timer function. I doesnt have to run off the ignition necessarily, right?



Hmmm speaking of which, it has a digital voltmeter built in with warning... I wonder if I could feed it the volt signal from the water temp sender and have them displayed... and then set the warning where I want according to the sensor output range... Hmmmm..



OK Im gonna try it, I cant hurt anything right ( famous last words), if anyone has any tips, or can forsee problems ( alarm, etc etc) please let me know..

It should work just fine. Not hard(power/ground/ignition) but the thing is...why would you want the fans on when the car's off? to cool off the water that's in the radiator?

That is what I thought upon reading this. The problem is that the water pump would not be actively moving the coolant (in the whole coolant system), thereby, the only thing you would be doing, is cooling the coolant in the radiator.



BTW, nice to see that you're on this forum too Richard!

I was thinking to just help move some more air through the engine bay.



Since the water is not circulating it wont cool down the block much, but anything I can do to cool the engne bay and preserve the hoses and stuff seems to be beneficial

I'm sure it could work well for that. I'd jsut invest in a good aftermarket hood just to have piece of mind....especially if the TT doesn't turn off and run your battery dry https://www.nopistons.com/forums/pub..._DIR#>/sad.png

Yep I have a vented/ducted hood. I usually pop it when I can after parking, but sometimes after mtn runs we congregate and talk ****, and I like to keep my hood closed to keep them guessing https://www.nopistons.com/forums/pub...IR#>/smile.png



Anyways I just thought this might be an easy way to do it... perhaps I can utilize the ground wire used in the std fan mod for this purpose.
