Update 4: (Hopefully My Last Update for a Coolingmist 2 Stage W/I Kit)
After a few weeks of waiting on a new hose fitting, I'm now able to run my 2 nozzles again. I'm currently running the M3 near the IC end tank (w/90deg facing the IC), and the M5 near the TB (w/90deg facing the temp sensor). My M3 has a boost switch that is set for 11psi and the M5 has its boost switch set to 16psi.
With these nozzles and settings using only -20deg blue windshield washing fluid, I can now hold HOM in any RPM/Speed/Gear. I have my water pressure gauge reading between 100 and 140psi when the system is spraying.
In my earlier testing, I was assuming I needed more Meth or more pressure or a lower boost switch setting. After several months of trying different things, I have come to the conclusion that holding HOM with S2 w/Toys requires a large quantity of fluid. Based on my fuel injector size, I've calculated that the combination of an M3 and an M5 is the most extreme nozzle configuration I could possibly run. I will be lowering my pump's pressure setting until the HOM kicks out, and then I will increase it a little to make sure I can hold HOM reliably without using too much pressure & flow. With the -20 deg washer fluid, I'm only using a 35% Meth to Water ratio. This means that more meth isn't always the best solution to maintaining HOM. I believe this may also hold true with the S3 w/Toys as well. I think it just needs a larger GPH nozzle configuration and more than likely a decent progressive controller. I would definately be using a Progressive controller so that I could get as much as possible from the W/I system, but right now it's a little out of my budget. That's why I have been trying my best to get the most out of a basic 2 Stage coolingmist W/I system. If anyone has any questions about my setup let me know, and I'll try my best to help you out.
