Interesting, never given the pump too much thought before, on track my temps are always good, on a dyno it's another matter.

I would have first thought an electric pump might be the way to go for more efficiency, Tony has gone that route I believe?

Some late BMW's use an electric Pierburg made water pump...controlled via the std ecu...we were trying to get a wiring diagram for it.

Water temps no, oil temps yes. Cooling is always welcome, less high drag radiator intakes needed, more speed!

I don't know if this applies to you, you may have already done it. I found getting air through the rad was very important for temps, this summer I sealed my rad by adding sheet alu on the sides and the top of my rad which met tightly up to the profile of the grill/bumper etc this ensured air coming in could only go through the rad and not around or over it - which is often a less restrictive path.

Now I have had it on the sides for years but I added a top peice and my water temps dropped by a good few degrees. (something like 6 degrees I think).

I need to add some ducting around mine, as I have the oil cooler, then a Rallye intercooler and then my radiator. Even though it's a Corrado VR6 one, it struggles when the temperatures get above 30 Celsius.

yep - the gurney will cause a negative pressure zone behind it and suck air out of louvres
