I spent some time searching LPG in here, but couldn't find much info.
Maybe it has been covered & I didn't search enough ;[
Spark timing for LPG burning is around 16 deg before TDS.
HHO spark timing at 8 deg after TDS with the waste spark eliminated.
Can HHO be used with LPG (at around 1.5 lpm) is the main question :?:

I'm thinking if spark timing can be progressively varied from TDS at
idle (with HHO trickling in) to 8 deg after TDS (after 1,100rpm) that
maybe LPG & HHO can be used together. An impulse reading of the
rpm could be used to vary the spark timing. I'm thinking out loud here
& would like to hear pros vs cons by people in here. Feasable ?
Cheers !

LPG Vapor, at the top of the tank is at 330 PSI. The regulator/ expansion vaporizer bring it down to 0.5 PSI, but higher flow to the carburetor.

You may want to reconsider your thought of just opening it, and letting it out. Propane boils at -44 degrees, and if the outside temperature is say +60 degrees, you are going to have a lot of propane converting to vapor state in one major and uncontrolled hurry.

If the outside temperature is say -60 degrees (which it gets here at times...) you can carry propane around in an open 5 gallon bucket. You can even pour it onto a burning fire that has say garbage burning in a barrel. At those temperatures, it burns like diesel fuel.

lol!!!
thanks for your concern, but i was planning on sealing the bottle first.
all LPG cars in nz have a tap valve on the bottle before it goes anywhere.
so i wasn't going to let the LPG just vent.

Hi Jehu. Over 5psi turbo boost will leak with old lpg systems. I'm more
interested in using the highest flowing lpg injectors that Ford are using
on their factory lpg xr6 turbos. Or aftermarket ones similar in size. I'll
need a lot of diluted HHO running through 2 staged regulators & play
with the timing to suit the burn speed/rate. I made this thread hoping
that some people might feedback some info they have heard about the
use of lpg injected systems. I'm not stepping back to an N/A systen to
run HHO. I'd rather nut out this HHO to suit a blown system. Jehu the car
is an engineered 92 auto awd 2ltr Lancer that is still rego'd yearly. I made
the driveline 3 yrs ago. LSD front & rear & switchable awd/fwd. Unbreako.
Cheers !
