I currently own an 02 Libby with plans on buying an 06 CRD. I'm trying to plan what mods I'm going to make and was wondering if anyone had tried water/methanol injection in their CRD. I don't even know if there is a kit available. There is an article in the March issue of Diesel Power in which they installed the kit on an 04 Dodge.

Never heard of it. Propane has been the boost of choice for Diesels as far as I know. Have not heard of anyone doing propane on a KJ either though.

I haven't seen anyone doing water or methanol injection on a CRD yet. Typically, I'd expect to see that used in conjunction with other power-adders, and not by itself.

So I did a little research, which I should have done earlier. Apparently the methanol/water injection is for intercooling the boosted air. Kind of a neat concept, wonder how much it has been tested.

If I remember correctly the name of the company is Snow Performance. I wonder if you could adapt one of their kits to a CRD? Hopefully they'll come out with one.

Water/methonal injection can give a small boost in power, however its main use is to help keep egt's in an acceptable range. It works out either when you chip your diesel, pulling a hard grade (with or without a trailer), or if you like to mash the skinny pedal a lot.

I was at SEMA earlier this month. Painless Performance was showing off a brand new water/meth system (called the Cold Shot, or something like that). They said they plan on being in production in Spring 2007. Seemed pretty spiffy and decently priced.

Aaah, found it:

It is the Cold Shot. About 3/4 of the way down the page.

For safe power I tried a trailjammer module by edge products. Very impressed with its power. by just flicking a switch my jeep can beat a lot of cars off the line and up hills . Anywae it was worth everypenny to try the Trailjammer.
I'm kind of scarred of that propane injection stuff. It seems that if its not installed correctly in could cause a fire or explosion

Sorry I just remembered their website(duh) http://www.edgeproducts.com/

There are ways to "add" power to the KJ diesels, however I can say I'm not exactly thrilled by the way some things accomplish it by just mucking with the signals between the ECU and the component. For instance, the Edge is tricking the ECU into thinking the rail pressure is lower than it is, so it accordingly raises rail pressure, causing more fuel to be injected than it thinkgs there is. This will also negatively impact the fuel mileage as reported on the EVIC since more fuel is being injected than the ECU thinks. A few things to consider when hopping up your VM engine.

1. Turbo speed limitation, about 150000rpm. There are controls for fuel maps in software to make sure this isn't exceeded (calibrated using an instrumented turbo). By mucking with signals, you change the ability of the ECU to properly manage this. Exceeding this limit is bad news for the turbo.
2. Cylinder head: made of cast aluminum. At peak torque/power, cylinder pressure is upwards of 160bar. Add more fuel and boost = this goes up. Too much over where it is and the cylinder head and gasket become very unhappy...I've seen both break before.
3. Crankshaft supports: cast aluminum as well. Too much abuse = order new engine, at your expense.
4. Pistons: Cast aluminum. Same story, different part...

Water/Alcohol injection has been around since WWII. Some old cars even came with systems back in the 60's so it's nothing new. It just isn't common. I used an Aquamist kit from the UK in my Grand Prix before I bought my Intercooler. I was pleased with the results. I used to use the blue washer fluid since it was basically alcohol and water. http://www.aquamist.co.uk/

Anything that adds more power to an engine is going to most likely cause all the effects that you have stated the a engine module will do. Its just like adding a 4 barrel carberateur to your 440 hemi. If you want more power you have to add more fuel or spin the turbo faster, its just a simple mechanical fact, you can't get more power for free.
If you want to run a wimpy 2-barrel carburetuer on your hemi then go ahead, but I assume that you probably have the cabibilty to add more fuel then that.
If you carefull monitor your egts than there is no harm in using a performance module.

MrMopar64, seems you are the one to speak to about the VM motor given your sig.

So what do you think is the safest and most practical way to achieve a bit more power out of our 2.8CRD KJ's ?

Given that DC has put 3 versions of the CRD into the KJ, I bet there's another version waiting to be released ? perhaps a twin turbo 2.8 CRD ? or maybe a 3.0 CRD with VGT ?

Personally I think the DP Chip or another of similar qualitites are the go.
