I wanted to get you guys thoughts on something. This is on my pulling garden tractor with a turbo'ed 3cyl kubota engine. It has a 250 psi water injection pump.
I have been playing around with
different combinations of water nozzles and came up with an odd thing. My
current setup is 3 90 cc nozzles (one in each intake port) and a single 250cc
nozzle in the crossover pipe. With this setup my EGTs run around 1600. I tried
replacing the 250 with a 90 and a 180 (which would add up to 270) and it runs
hotter at about 1700-1750 deg. I can't understand why it runs hotter with
slightly more water. I'm running straight distilled water. Any ideas?
