(02-07-2020, 04:44 PM)TwoMuchBoost As Petar mentioned, with stock 6mm elements, the extra fuel when trying to make more power comes very late in the cycle. Have you tried re-timing the pump with more base timing? A few extra degrees of burn time in conjunction with some water injection will get you where you need to be + more power.
It's weird, when I was on stock pump on my 603, the water/meth injection didn't reduce but in fact added EGT as it was underfueled/lean and really loved the extra fuel. It also equated to a very noticeable increase in power. And this was with only a 70-30 water/meth concentration (typical blue winter washer fluid). On the flip side, when the car was smoking heavily after having a bunch of extra fuel from the 7.5 dieselmeken pump, the water meth actually lowered EGT as it cooled air temps down and increased charge density. The methanol has a much higher volatility and acts as a catalyst for the diesel too.
The other side effect is the extra mass of the steam going out the tailpipe lights the turbo like you wouldn't believe. I've noticed the sooner you can start feeding it in without quenching the diesel combustion, the faster it spools. If you have a variable controller it's a fantastic spool aid as well.
That's interesting and definitely doable in the DSL1 software under pump angle control : setpoint table. Try that JAV1
