Well I have tried it with one nozzle and it is a lovely fine mist, this is with a 160 psi pump which keeps cutting out. So I need a bypass and/or another nozzle but I have to get some other fittings to be able to do that.
Will be just a fine mist, controlled initially with a manual switch, if it gives me an improvement I will look at a boost controller that changes pump speed.
At the minute just cobbling together bits to make it work, if successful will do it a bit more betterer.

Here is a propane injection post from a guy who runs a yank old bus forum, just added to his second bus and is pretty happy, just uses on the hills

Commig south into elesibethtown ky on I65 a good long grade last time I crossed the peak of it I believe in the 40 mph range. Lots of black smoke and lifting of the throttle while slowing down... With the propane I never dropped below 65 mph never any black smoke and less then a 5 deg or so engine temp raise which was way less than 10 deg climb without the propane

I don't expect the same without adding methanol, I may do that if I think it will be worth it, but probably not

The LPG fed into the intake either before the turbo or after the turbo and before the blower. It will also drop the temp if you feed it in as a liquid at the nozzle so another one of your fogger nozzles should do a good job there. Start out using a caravan bottle upside down, an LPG solenoid for the one/off and try it out.
Not too sure about his claim that the black smoke stopped, the LPG is adding another fuel so even less oxygen available compared to the fuel load, even more black smoke

His is an old 8V71, no turbo, just fed in through a small orifice before the blower at about 7 psi if I remember rightly. found the same thing on his other bus as well, maybe the more complete combustion kills the smoke ?

Ok 2 nozzles are hooked up but pump still turns off at 160 psi, takes much longer of course.
I don't want to add another, I think what is coming out of 1 may be sufficient, 2 perhaps would be right at full noise.
So will have to get a flow control valve tomorrow to allow a little bleed back into the tank.
Ah, the joys of cheap innovation !!

One last part to automatically fill the tank I have made and then it's all done ready for testing....................
Some vacuum switches on the way, simplest to run it off vac than try to find a place where I can get a takeoff to read turbo boost.
And of course it is bloody raining !! Grrrr!!
