I ran some tests over the weekend on my intercooler sprayers. I have three 0.3mm nozzels spraying onto the intercooler
and I monitored engine/inlet air temps whie cruising on a long flat in 5th gear at 60mph. Over about 2 miles, I noted a
drop of about 5 deg F in the inlet air temp. Not a large drop and not really fast enough to be usuful on the drag strip but
then it was only 2 Deg C outside. So I shall leave that unplugged for the winter and test it again in the summer.

I also ran tests on the water/methanol injecting while monitoring engine coolant temp. I manually injected the fluid while
cruising along, so the engine would have increased/decreased fuel to maintain speed. There was no notable change in
engine coolant temps with the water/methanol mix at 50:50. Next I will try testing this by holding the accelerator
constant and allow the speed to change to see what effects that has on the running temp.
