i have a 99 3500 dually w 4" exhaust all the way, edge programmer w holly blue lift pump. i just put in propane injection which was very cheep compared to online kits if you do it your self. were should i be around power wise the edge did a zero to 60 in 8.5 on #2 and 7.3 sec w lpg and #2 o and the stock holsett is blowing 34 psi

any questions on the lpg set up let me know i run it on a hobs pressure switch that comes on at 4psi works the nuts.

 

if you were to through it on a dyno, it would put it around the 250/500 mark but that may even be a bit hi, if you have stock injectors, you are pretty limited, the one we had at the last dyno, was an 02 6 spd with mach 1.6 injectors, a smarty ecu, exhaust/intake, fall fuel system, and he put down right about 290/550, i am interested in your lpg setup, lets see some pics and info on how you have setup

 

i would love to how do i put the pic on the forum ?

 

start a photobucket acount, load the pics to it, then just copy the " IMG code" and paste it in the reply, and they will show up when you submit the post/reply

 

 

i have the fork truck tank in the bed which feeds liquid lpg to the solenoid that only opens when it sees 4psi or more from the hobbs pressure switch that is t ed of the compressor housing. the regulator is also a vaporizer that uses my heater core lines to warm up the lpg before it is let into the intake.

 

awsome! i have been thinking of a similar setup, only i have a trans cooler in the radiator, i was thinking og passing it through for the vaporizer... i have plenty of pressuer operated switches for my water/meth systems, how much flow do you have going in it? is there a pressure regulator on the tank? or is it just straight to the vaporizer/regulator? notice and mpg gain?

 

use the atf to heat it ? the millage is better but i am not a consistent driver. the next high way trip ill run it but im always screwing up the millage by gunning it haha.

 

oops! sorry, my rad. has a atf cooler inside it, that is not being used, as mine is a manual, but i thought it may be a cheap alternitive,

and i know what you mean about mpg's the way i drive, i get about 13, but get it on the hwy, with out the thrill factor of stabbing the throttle every time i grab a gear, it gets up in the 20's

the reason i was thinking of using the atf cooler is the limited spase under my hood due to this mess...
