I know there is another thread area for this, but no one was really talking about the 6.5TD....So my question is, does any body have a water/meth injection system on there 6.5? How well does it work? I've been reading about them and I'm interested in everything but the price...Has anyone made their own? I see the Snow kits go for around $500...

I would be using it for fun around town, and especially when hauling my Jeep around on the trailer ~6k lbs.

Please Discuss....

In FAQ section is a link to WMI, see if that answers any of your questions, if you still have more ask again, several members use it.

OK, I've read the WMI section in the FAQ's and still have a few more questions:

- I'm looking at a nozzle with these specs:
Spray angle = 90*, flow rate at 60 psi = 0.2 gpm (30oz. / min), drop size of 86
microns, length = .75 inches, max temp = 800*F, output pressure = 94.7 psi

- I also found this pump assuming I will use the above stated nozzle:
Moves 1 GPM at 60 PSI, self-priming up to 6' away, pressures up to 100 PSI

I will use a regulator so the nozzle will not see anything over the 60psi unless needed otherwise. I have the rest of the system figured out, but was kind of shady on the nozzle and pump. According to the FAQ's section most of you are running an average of 30oz/min (0.2gpm). That is going to be my starting point and will adjust from there according to my needs.

Also, I'm still running vac pump and my turbo is putting out stock boost. As I sit now, when I run 65-70mph I maintain boost around 5psi. I don't tow anything and if I do it's light (1-2 tons). I do punch it every so often (who doesn't), which will get me to about 10-11 psi for a couple seconds until the tranny shifts. Once a year, I do travel up North and climb some grades of about 6% which give my turbo a good workout. I also use my rig for recreational off-roading which is why I'm staying away from the IC. I travel low speeds at high RPM's, especially when climbing the hills. This will give me around 5-6psi as well.

So with all of that I have one more question. I'm going to put in a pressure switch so the WMI will kick in at a certain PSI. I was thinking maybe 4psi. Is this too low? I can alway adjust my flow rate/nozzle so I won't dump too much water. What PSI would you all recommend at the above driving styles?

Any insight or comments would help (I may be way off and if I am, don't make the lashing TOO bad;)

Thanks

Having not been too familiar with WMI myself, just wan't to pose a question here. . . what is the better method of engaging your WMI? Using temperature, or pressure?

IIRC the Heath WMI kicked in at 10+ boost

10+ plus boost I never see unless it's floored. And even when I do, I only get it for a few short seconds. That's why I was saying around 4psi for me. Is this too soon?

4 psi should not need WMI, sounds like you got the cart before the horse, high IAT doesn't become a problem until you are making high boost better than 7 psi you start knocking on high IAT problems with right ambient conditions, 10 psi is where temps really start climbing, so you got to get more boost 1st, either with fooling or turbo master.

Do you have EGT & boost gauges ???, from your sig you aren't much more than stock in the power dept so WMI won't gain you anything to speak of, if at all.

Go to the more power thread in FAQs, if you don't have both EGT & Boost gauge start there, then start adding boost & fuel.

Have the boost gauge, but no egt gauge. I'll get one and see what's happening first.

this is the all important question, but can't be answered w/o knowing your goals. If your goals are to tow higher loads, at lower egt:

Trigger with temp, modulate with boost, sice higher boost requires more water. You'll want to conserve for a towing application, and an intercooler is the best thing for the towing app. I would say 7-8 psi

If for pure performance:

Trigger at a lower boost threshhold, 4-5 psi, temp is not important really unless you want to create a water miser type application, the most practical IMO.
