There is a mileage bonus with water/methanol, but you do need to have some injection at your cruse boost level all the time. I usually set up injection slightly above cruse boost like 1 psi.Is there much benefit in this? What are your mileage comparisons between water on and water off?
As you know I have been running WM for quite a few years, I have never noticed any 'significant/verifiable' change in fuel eco at various WM settings and I've had a few. To go that way I would need a much, much larger tank which I would love to do but don't have the room and I don't want a tank under floor for many reasons. Like you I have my injection starting just above cruise boost so I can get the K's out of a tank.There is a mileage bonus with water/methanol, but you do need to have some injection at your cruse boost level all the time.

On longer trips you should see 80 to 100 klms extra per tank on a TD42. Its more about water/methanol volume cost to bonus mileage. There is hearsay evidence suggesting 14ltl/100klm to 11lt/100klms. I rarely bother about economy it is what it is but i have broken 10's at times on conservative driving on long trips usually not me driving though. But that's not a comparison as such but a TD42 doing 10's on a trip suggests water/meth is doing something.
I understood there was in theory but I was interested in actual experience if you had any data. I just didn't see much benefit with injection at lower boost levels unless there was a substantial increase in economy. Low boost injection has the significant disadvantage that it runs the tank dry before you know it unless the tank is huge.In theory there is Overboard, but I have never tried to do any proper testing to prove it.
I still have the solenoid in place, just in conjunction with a boost switch.Got rid of the boost switch as it’s activation point isn’t reliable. (Apparently can be done )The second nozzle will dribble and not atomise properly due to lower pump pressures unless a very small nozzle is used like snow #1 60ml/min . Snow rate there nozzles at 60psi pump pressure
Worth a try mate.I’ve always wanted to add a second nozzle to my setup but didn’t want to add it for the sake of having it unless there was some benefit.I’m more than happy with the single nozzle at the throttle body, which works extremely well. After seeing the promising results @geeyoutoo has had with the IC inlet location of a second nozzle I decided it was definitely worth having a go as I’ve got most of the fittings to do it. Just had to order some elbows and another nozzle (should arrive some time next week). For those of us that have a HPD IC the inlet pipe is just under half the length of the CCIC (cross country ic) inlet. The HPD inlet gets completely covered by the silicone hose compared to CCIC. After spending a week ring various companies/ business to get 40mm added to IC inlet,no one wanted to do it. It also meant that the intercooler piping had to be measured cut to length and re beaded also. I spent a couple of hours looking at ways off manipulating the silicone hose to gain some room but that’s simply not possible. The ic inlet pipe covers almost 40% of silicone hose and there’s a 1-2cm gap between intercooler piping and ic inlet pipe. The plan is to stick a 90deg elbow nozzle holder in between gap between the beads of each end . This allows the nozzle to sit in the ic inlet pipe past the bead . Just waiting on nozzle to arrive with 90 degree elbow
