Yeah sorry didn't mean to sound patronising.[:p]

I do have a manual overide switch for the thermos however I find this very ineffective as I can still see the coolant temp rise after the engine is off, sometimes reaching 110 degrees after a session on the track and coolant pisses out. I really like the idea of the pump which by the way can also turn on the thermos while coolant is flowing for 2 mins or 5 degrees below the controller setting (whichever comes first). I think this aided with a cooldown lap should keep the engine/coolant temps under control, I've also purchased an N14 50mm thick radiator which seems to work really good when there is air flow. Also purchased some heat wrap for the turbo manifold as the ceramic coating does a poor job of heat supression, can't beat the good old heat wrap.

Yeh 110 is starting to get on the high side. I am surprised the thermos don't keep it cool after you turn it off. Are you sure you haven't got any other issues? Like a crappy rad cap or thermostat??

Well the Davies Craig Pump and controller are fitted and i'm very happy with the results, the pump works very well and my thermo fans hardly have to work at all. When I switch the engine off the pump does continue to run and holds the engine temp where it turned off, if I switch on the fans also the temp dramatically drops. I've only tested with a 13PSI cap and tonight I'll give it a run with the 18PSI cap.
The pump is very quiet and you have to listen hard to hear it working. the real test will be at the creek on Mar 2.
