in short, when the fans come on, they draw alot of current, which basically takes away current needed for vital other components such as fuel pump etc. If your giving your car a bit of stick and the fans are on, the fuel pump might not be able to draw enough current thus meaning not enough fuel which equals melted engine
the other issue is that the standard switch comes on quite early and stays on for ages
the switch you have bought will mean the engine will get hotter but the fans will come on later but for shorter cycles as opposed to coming on early and virtually staying on all the time
thats my understanding of it anyway.....there is a thread about it somewhere, i'll dig it out
ps. if you havent already done it, rewire your fuel pump, a must for cossies!
