Hey mate i dont have any pics, but my setup is;
Coolingmist 150psi pump mounted on lhs wheel arch in the tray, 15l bunnings water container nearby.
Solenoid valve and then the 2gph devilsown nozzle mounted in the intake on the top of the curved pipe.
A pressure switch is T'd into the boost sensor line, which feeds the power to the pump and solenoid.
I have a switch in the cab to cut off power to the boost switch and hence everything else. And also a led light connected to the +ve of the pump, to let me know what boost pressure its coming on at.
Got mine coming on about 10psi, but have hat it as low as 5psi without problems.
At a 30% meth to water mix you can definatly feel the better acceleration thru the gears, and 40% even better, but more methanol means higher egts.
Hope i answered your question mate
