I'm also thinking of putting the EWP150 on my 308. I was planning on utilizing the controller. Keen to know how you go with it on the six.

Keeping with the same thread, Davies Craig website says to go the biggest single fan possible, does any one have experience fitting a single 16" fan to a standard 308 Radiator (not sure if it will fit) If not anyone know what size twin fans will fit?

Cheers

I cant comment on the fan, but if you're utilising the controller, the EWP150 will work great... Some people choose to run the EWPs in open loop with a restrictor plate or a thermostat with a few bypass holes drilled in it, but if you do this, do not over engineer the setup as you can actually struggle to keep the engine to temp. I know of a few blokes who have not been able to get their 308 to operating temp when using big pumps like that in open loop. The controller is a very good thing and will look after all of that by helping startup warm up as well as pulsing the pump to hold the desired engine temp. 

 

Im all for running engines cool but too cool, like 160f or lower is no good for long periods of time.. If oil cannot get to temp it can cause issues.

I have used an elbow and blanking plate from Aussie speed, then wired pump in open loop with a 170f thermostat with bypass holes drilled. I have a controller and will fit this soon just for improved warm up ability, this takes forever to warm up. Holds 170f with no mechanical fan and with the thermos off on most days in cruising state. 

 

I then ran a shorter fan belt and trimmed the timing cover pointer to allow the belt to slip under it. I noticed the revs raised by 200rpm at idle when I first fit the pump- this surprised me as I thought the increased alternator load would offset any reduction in drag from the mechanical pump at idle, but it appears that the weight of the old mechanical pump and friction was greater than the increased load on the alternator (what else would explain the 200rpm increase in rpm).

Here is another forum member who setup an EWP on a holden 6, some good info and tricks in here;

Cheers for the info. modified thermostat could be the go here then. not overly warm in the souther end of WA so keeping temp will be important. Thanks again.
