I have a single seat Short Sand Cars mini long travel with a stock busa and a Griffon Radiator directly behind the seat, more than likely the same set up as you except I had three aluminum bungs welded into the side tanks. On the left side just above the lower radiator hose is one which holds the fan switch and the other 2 are on the inlet side slightly below the inlet hose, one is for the coolant temp sensor for the gauge and the other is for the sensor for the motor.

When it is hot, 90+ in the dunes and I run it hard the temp according to the gauge is around 225 - 230 and the fan cycles. My experience is that the coolant temp gauge never lasts more than 2 seasons due to the all of the vibration. I use it as more of an go no-go indicator than a temp gauge. What I mean by this is that I have the gauge installed so that when the coolant temp is in the 220-230 range the needle points straight up so that all I have to do is glance at it while duning to know what is going on, straight up everything is fine, 45 degrees to the right she is too hot time to cool the motor off.

I am curious if anyone here has any experience with the after market super coolants (water wetter etc.) *and if they really lower the cooling temps 20 degrees.
