At the moment the second fan (drivers side and oil cooler) only comes on when the air con is on. Whilst the engine has not been pushed yet the plan is to install an over ride switch that can turn the second fan on without having to turn the air con on. Current indications are that when the engine starts to get hot turning the second fan on does have an impact, however no real data yet to 'prove'. Next time I'm on a track I will get some more data on how effective this set up is and will post some more results. The only data I have collected so far is some stop start peak hour traffic (air con was off in the interest of catching some data).
The other suggestion is to remove the air con, however on a recent Darlings Down club run when the air con did not work properly the other half would not be happy with no air con (and neither would I).
Notice the shroud has been folded to allow the fans to draw as much air through as possible.

Data collected during peak hour in Brisbane (Oil temp purple, water temp green, oil pressure black, revs light purple, speed light black). There is a legend in the right hand corner to help.
Note the speed is not being recorded straight away, it is lagging. An ABS sensor from an NB is being used and there maybe too many teeth (44) for the Innovate. An internet search has suggested that only about 4 teeth are needed to record speed so I will need to investigate this further, never the less the speed is accurate once it starts registering. The other issue could be the scale being used to record it again I need to test this further.
I have attached the first 17 mins of the data in Excel format (12,500 lines and about 2 meg)
Start of recording and stop start
7 mins in more start/stop start
56 Mins (stoped)
63 Mins (starting to move)
