I am looking for something on the truck that will tell the LPG solenoid to open to let around 4 psi LPG vapors into the inlet side of the turbo. Boost will not work, Because when the exhaust break kicks in the boost goes up over 5 psi (you do not want LPG going into the turbo when you are trying to slow down).
Just cruzing flat highway 55 mph around 4 to 9 psi boost. Just goes up fast when on any hill or if you speed up slowly.
36 psi max on the boost stepping into it.
Fuel PSI would work. Watching all of the gauges when driving, as soon as I step onto the go pedal, Fuel PSI goes from 4,000 - 6,000 up to 8,000 psi and climbs up to 26,000 PSI when you lay into it. OR on a BIG HILL PULLING RV. Let off and it drops like a rock to 7,000 to 5,000 PSI. Does not matter if the exhaust break is turned on or off, (OFF it still kicks in on the top gear you are in when slowing down. ) (on, it hits all the gears)
So I am thinking of getting a PSI Switch that has a range of 0- 30,000 psi and can be adjusted to the 8,000 psi for the contacts to close. sending 12vdc to the relay that will open the solenoid valve on the LPG tank regulator. I can mount two 20#'s or one 33# vapor tank(they are rare tanks) that is made to lay down on its side. (most side mount are liquid LPG tank for fork trucks that lay down) I don't need liquid. I most likely would use an 3/8 inch line to the intake.
BUT where to tap into the fuel system to get that PSI. I did put in fuel shim's to raise the fuel dump PSI to 26,000. some put plugs in there to let it keep climbing. But I want to only let it max out to 26,000 psi. so where else could I tap into to get that reading????
( I fill propane bottles for my living 250 to 300 a day.) (Propane is cheap from where I work. Boss/owner asked me if I had propane on my truck. He told me to do it and we get bottles filled for free. No big 100# or home tanks please) I fill his and the drivers BBQ and heater bottles all the time.
So I need to get this put on.
to save on Diesel fuel.
What's you think?
