We have been working on an uprated fan switch for these for some time, which will bring the fans on slightly earlier, and bring the temps down slightly lower before switching them off. we see lots where the coolant temps are way too high and the same principle has worked really well on the cosworths,
As an added bonus, we were aware of the problem with the switch plugs being broken and burnt, so we have worked to get a switch which comes pre wired with no plug. so you can throw your standard plug in the bin, and connect our new switch direrctly to your loom!
Im currently testing them, So watch this space, they should be released soon!
