School me..what is it..for the 7.3 ..goods and bads.. and whats its worth..

15 gal bully dog kit?

 

also they guy said it adds 100hp... i have my dp tuner on the way.... adding all that ..would i be ok ..or i would have to upgrade?

 

Taken from Wikipedia: LPG injection for diesel vehicles
The performance, economy and emission profile of diesel engines can be improved by injecting a small quantity of LPG into the inlet manifold. It is claimed that the LPG increases the burning efficiency of the diesel fuel from typically 75-85%, to 95-98%.[4]

The systems typically operate by metering a small quantity of LPG, at a pressure slightly above atmospheric, into the intake manifold, where it enters the combustion chamber and is ignited with the diesel. LPG flow is regulated to ensure smooth operation, and will typically only deliver LPG under power.

It is claimed that such a system can result in a 10% to 20% increase in power and torque,[4][5] and a reduction in overall fuel costs. Any actual savings are dependent on the relative cost of diesel versus LPG. In Australia, where diesel costs substantially more than LPG, savings of 10 to 20% are claimed.[6]

The above systems add small quantities of LPG with the primary aim of improving economy, but much larger quantities of LPG can be injected in order to increase power. Even at full output a diesel engine runs about 50% lean of stoichiometric to avoid black smoke production, so there is a substantial amount of oxygen in the intake charge which is not consumed in the combustion process. This oxygen is therefore available for the combustion of a substantial addition of LPG resulting in a large increase in power output.

Benefits, cost wise, will depend on the cost of the LPG as stated above. Jody offers tunes specificly for the use with propane injection. You will need to contact him about these custom tunes.

 

I believe Roland covered it pretty good. LPG can be used in small quantities if setup and controlled correctly. I would only consider propane in small doses to help out on economy and towing, I would shy away from using larger amounts for the use as a larger power adder. I'm not saying for sure that it will, but there is a good chance that it will grenade the engine in anything more than a small amount, it may or may not happen right away, or it may be 100k down the road. If you are looking for a power adder, stick with nitrous, its alot safer and alot easier to tune for. Or go with slightly larger injectors and turbo if you are looking for power and economy, anything to get away from the split shots will help out.

 

1) don't even think about it unless you have a large measure of self control. It is very easy to get a very large power boost out of propane, but too much will window your block. It is very easy to turn up the amount of propane "just a little more", so if you are always pushing the limits, it's not for you.

2)Propane advances timing. Only run it with
A)tuning specifically for propane, or
B)tunes of less than 40hp gain
or you will window your block.

3)Don't expect to save money on fuel with propane fumigation.

 

the reason i posted this was because..someone had em and wanted to trade a whole setup for train horns.. train horns are what i do so it wouldnt cost me much..

but i just got my DP today...then i hear some of the stuff that you guys are sayin and i thought i should just sitck to me chip and forget about the injectors.

 

Clux & Roland have you sorted; i thought about it myself as a way to boost economy, but unless LPG is ~1/3 the cost of diesel, it's financially a loser. Add to that the potential for killing your engine... no thanks.

Stick with the DP, they'll have you smiling bigtime. Mine is ordered (and hopefully on its way!) and when I eventually step up to a 38r turbo & Stage 1 injectors, I'll go for live tuning and call it good. I'm not building a racer, but making the truck more enjoyable to drive with a bit of a power boost, but (most importantly to me) not losing anything in the way of reliability or longevity.

 

ya thats exactly how i think about mine.. my chip literally just came in
