Engine/Transmission (1994 - 1998) water injection

[MMcCallie]

Detonation can occur on any engine, gas or diesel. Water/methanol injection offers big improvements for both gas and diesel engines, more so for diesels.

Jim,



What do you set the two stage to come in at as to not to drown out the fire?

I'll be trying 20 & 40 with top boost about48. Does this sound close with 50%. ?

I use a hobbs switch to turn mine on but on a stage 2 controller those numbers are fine. Just don't start it too low and top it off lower than max boost to ensure you have it at full pressure.

Thanks for coming here to help these guys out! As I told "Ahopper" I knew you had done alot more R&D with your system than I had.

IMO, the detonation is not as big an issue on the 24 valve engines and even on the CR engines because of the "variable timing". As myself and others have pointed out, the older P-Pump 12 valve engines, (94'-98. 5) with the mechanical or "static" timing do not enable you to "start out with lower timing and raise timing as the RPM's of the engine come up. " If your timing is set say at 20 degrees, you have 20 degrees at idle and you have 20 degrees at WOT!



"Joaker" maybe some of the 24 valve or CR guys can get in here and give you some input. I can tell you that a friend of ours here is running the Snow System on his 2005 Dodge CTD CR and runs a mixture of 30% pure methanol and water and does not have any problems with detonation like I have had with my 12 valve engine. Hope this helps you some.

ok so im installing my kit right now. i have a couple of Questions. wher on the air horn do the Two injection nozzles go? and if im going to be running at about 30-35 psi at max boost what should i set the two hbbs switches to? (stage 1 and then stage 2)? also how do i figure out how to adjust them? Also the nozzles i got were 1. 5 gph and 2. 3gph what size in ml are they and will they work?

Sorry I was not on here earlier to help you out some!



If you are not already done, what I did was drill one hole on the edge of the air horn near where the rubber hose is, but not in the curve of the air horn. Then drill your other hole a few inches inward from that first hole, but more towards the other end (closer to the valve cover). The idea is to "spread out"

the water vapor from each of the nozzles.



You asked about how to "set" the nozzles. If you are only going to be running 30-35 lbs of boost max, try setting the first one at around 12-15lbs and the second one at about 20-25lbs. What we do is to temporarily plug the holes for the nozzles and run the hose with the nozzle attached up under the hood and tape it to the windshield. Then, go for a ride, turn the system on and get your boost up to where the nozzles will spray from both stages and you can then see if everything is working O. K. If that all checks out, put the nozzles back in the air horn, and go WOT to see if the boost settings are giving you the cooling you need and want. Some "trial and error" will be necessary!



Hope this has helped you some.

so does anyone know what size nozzles they are and if they will workon my truck? i really appriciate all the help so far thanks

 

[Ahopper]

btw Jim: thanks for the pic ive never seen that clean of an engin!!! :--) i wish mine looked like that!!!

 

[pwerwagn]

Those nozzles are really small.

Your nozzles are sized as follows:



1. 5 gal/hr=94. 6 ml/min

2. 3 gal/hr=145 ml/min



Just for reference, snow uses 625 ml/min nozzles, which is roughly 10 gph.



hope that helps,

Jeff

Yea looking at that pic I see I had my first set of Twins on and a borrowed pump due to the blue color.



On the snow system volume when I ran one pump max'd out with (2) 625 nozzles it pumped out 1/2 gal per minute, when I ran the 66/BB Twin combo is when I put on a second pump running one nozzle. Both are just a little too much running a single turbo but you can drop back to the one pump, one nozzle set in a matter of 15 seconds.
