This kinda goes hand-in-hand with the cooler mod - so I'll post it here:

Wouldn't it be nice if there were an easy mod to put a switch on the pump and fan so they could be turned on while you're sitting in the staging lanes at the track with the car off?

Call me crazy, but I bet you could even hook it up to a temp sensor so that the fan and the pump automatically shut off after the coolant reached a certain low temp.

I know others have thought of it, and some have done similar mods, but it would be great to see a kit to do this for us guys that aren't exactly DIY-enabled.
