I was looking into water/methanol and propane and was wondering the pros and cons of each? I'm looking for something that helps with efficiency of the engine while towing. I'm not really all that interested in NO2 as that is more or less for racing applications(in my mind anyway, atleast that is where I see it being used most often). Is either or a good way to go or should I not bother with that type of stuff? Thanks for the help.

 

for all out highway driving propane injection is the way to go....water/meth is more along the lines of a power adder to a extent...because water cools the air(good for big turbos)and meth acts like a power adder. for a gas motor would be like increasing the octane...so i guess like a cetane boost for a diesel.

 

I'd go with Propane, but keep it light. Propane is also a power adder.

The water/meth can help to keep the EGT's from getting too high by varying the mix of water to meth. More water will keep it cool while more meth will add power.

The propane will add some power, but it's a bit easier to control (note- opinion here) and there are some good kits out there to get a fairly large tank that can mount on the frame making it last longer for those long trips.

NOS is not a power adder. NOS to a diesel is like a turbo in a bottle. It adds ozygen to burn the fuel. I have big injectors and therefore lots of smoke from unburnt fuel, the NOS helps clear the air by adding more oxygen to burn that fuel.

 

From what I understand about propane, it sounds like NO2 does about the same thing then. If I'm understanding propane correctly, it keeps the burn longer and therefore, helps burn more fuel then without it. Am I roughly in the ballpark or am I in the breeze?

 

I notice quite a few of the kits have it to where you can choose at what psi(on the boost) when the propane kicks in. What psi would you set it at? I'm leary at setting it to low because I don't want to use up the propane just for the casual driving either, more or less when I hit fairly good pressure like 10 or 12 psi? I would just want to keep it out of the normal stop and go stuff(or do they have a total shut switch? All I had noticed is you could program what psi it would kick in at. Also safety factor, both for the truck and the slightly eccentric driver(yours truly). You keep on seeing this horrible stuff about injection type mods, I'm sure quite a bit is inflated, but what are some things that a person should be on the look out for?

 

Call and talk with Matt (PSD 60L Fx4) at LIPD, he has alot of experience with water/meth injection etc and can steer you down the proper path for your needs.

If you do not have a tuner yet, you need to get an SCT XcalII with custom tunes from Matt. This should solve all your towing needs without Water/meth or propane injection.

Hope this helps

 

Check out the latest (June 2007) diesel power magazine, it explains the pros and cons regarding the different injectables and what benefits to expect. It seems as though propane is what you may want but I suggest consider propane only after having a SCT tuner as it provides some of the benefits.

I am consider installing propane for improved fuel economy purposes but have not began my research of which kit is best for my 6L application.

Done that, although I did get mine from a local shop here(Bean's Diesel Performance). I had just wanted to get some feed back from people(other then shop owners), what were the pros and cons of them in my situation.

 

I had seen that and that is what had gotten me thinking about it, I had just wanted to see what other people had thought about it after they had gotten it. I didn't want to base my decision on preconceived notions that were unfounded, just based on current misconceptions of what the products are really like.

 

tex25025,
Injecting nitrous oxide into a diesel engine will give you much more power than propane and although it is much safer to use on diesel than gasoline applications it is designed to accoplish a totally different task. you would not be able to run nitrous oxide in daily driving conditions as it runs out much faster and you would have to refill your bottle way more often than you filled you fuel tanks. nitrous essentially provides more air to burn the fuel with, combustion uses both fuel and air and all the fuel in the world will not burn without air (oxygen) so nitrous is used to provide air beyond that which is natrually drawn into the engine, creating short burts of very noticable power, because the engine is able to burn much more fuel than normal. Propane however is used in much smaller quantities and there fore lasts longer and enables you to use it all the time. Propane also performs differently in the engine, it does not add more air like nitrous oxide, but provides a faster burning fuel that helps the engine burn the diesel more efficiently. I have heard that diesel engines generally burn 75% of the fuel in the cylinder in a normal combustion stroke, but propane helps the flame spread faster to burn up to 95% of the fuel creating more power without consumiing more fuel, making your engine more efficient. A few other pros of propane is that it is supposed to keep your oil cleaner by reducing the amount of soot.
Hope this helps some.

 

That does help, I had figured propane might be the way to go, I just wanted to get some advice from people that have done it. What they would do or not do, what to avoid etc. and to actually determine if it was worth doing in my application since I'm not looking at this for a street performance angle, unlike most people(atleast the most people that I hear about) that use injection methods for their engine.
