Did a few half throttle passes last night at the track. And these are what the plugs looked like. Runing devilsown controller with two M5 nozzles and 150psi pump. start time at 2psi and full at 25psi. I was only running .9bar last night as this was the first time at the track. AFR was low 11's. EGT never went over 700c with timing at 20btdc under boost. Going back saturday to make some full 1/4 passes at 1.5bar.
I use to use a hobbs switch to activate the water injection. one at 5psi and another at 13psi. This controller is so much better.
