Any real pro's or con's to these?

Less load on the engine....

but...realistically you load up the alternator instead which still loads up the engine anyway.. as to the figurative differences I'm not sure.

Yea, that is pretty much what I was thinking.

Although another pro could be that you ensure a good water flow through the engine even at low speeds like sitting in traffic..

Could these be made to run when the engines off to help cool down or is this a stupid idea?

As weird as this may sound, I've seen a system very similar to this for those people who store their cars in the winter. You get two valve units which you fix into the car, and during the winter, you hook the car up to the system and it circulates warm water through the car to stop it freezing up.

As to running it through the engine once it has stopped, not really much point.. the engine isn't generating heat and there is no air movement to the front rad, so it won't really do much...however it would prevent cold/hot spots forming I suppose.

connect it in to the turbo timer some way?

What would be the point?? if the turbo timer is running, so is the engine :p

But yeah, you could use a turbo timer with a relay of some sorts to run an electric pump without any issues.

Yea, don't think I will be going for the electric pump anyway, there just doesn't seem to be enough reason to do so. Thanks for your input

Keeping the pump running after shut down is a great idea. Only problem with these electric pumps may be durability..... and if it fails it won't take long until it boils over.

A better idea may be the use of a secondary electric pump to circulate water. http://cgi.ebay.com/ebaymotors/BOSCH-ELECTRIC-WATER-PUMP-9-GPM-12V-PART-0392022002_W0QQitemZ110083089686QQcmdZViewItem

Those Craig David pumps are great for sprint, drag & hillclimb cars though! ;)

In race applications they have merit. They are wired with a switch to run after engine is off along with fans. Not much point for our purposes...mostly:)
