hey i finaly installed a water/methane injection.i'm still tuning and it's raining so i can't check it at the track. it's supposed to add 70 hp at least and lower the egt. haven't seen the egts drop yet. and the power isn't really noticable unless you turn it on under boost. like i said still tunning.
i would like to thank everyone here at FTE. this is a great site and i wouldnt know what i was doing without it!!!!!!!!

ps any comments on propane????

 

how much was the water/methane kit and what brand is it

 

southerforman
it was a snow performance. about $600.00 with a 8 gal auxilery tank.i mounted it in my tool box..they didn't have any on moter heven.

Here is the link to the Methane/Water thread that has been discussed here.

PSD 60L Fx4 ruined a motor with it, so read and learn from him.
Hope this helps

 

thank you plasterer

 

AlsodDo a search here in the 6.0 area...great reading on water injection
Plasterer is spot on that one is good thread

 

I still have my kit to install. Siince PSD 60L FX4 destroyed his engine I have been waiting for any other problems to crop up before I install it on mine.

 

Something to keep in mind; the water must be turned on BEFORE EGT's rise; it will not cool it down (at least not quickly) once they are already up; it is a preventive measurement. Mine runs about 200 degrees less at peak with straight water, about 250 less than windshield washer fluid. The peak drop will come at about a 35- 40 percent methanol mixture; anything beyond that will actually start raising the temps slightly with each percentage.

As for the boost thing, running water without sufficient boost will choke the motor. The engine is only capable of combusting a certain charge percentage of water; at low boost the water takes up a proportionaly larger percentage of the intake charge with the same given volume, because the volume of air is less. My first stage kicks on at 16 lbs now, with a .010 injection orfice. The second and third stages kick on at 20 and 22 lbs respectively, with .015 orfices, and the 4th master stage activates at 25 lbs with a much larger .030 orfice (this one will absolutely just bog the crap out of the motor unless running AT LEAST 25 lbs with it to the floor).

The low boost fueling on the six-gun setup is relatively low, so you need to raise your boost activation points up significantly. I would recommend activation at a minimum of 18-20 lbs of boost and nothing less; possibly even more if you are running a large injection orfice. If you raise the points and it is still not making any power, lower your boost pressure, as the flow is exceeding the point at which it will make power vs. rob power from stalling combustion.

When tuning the system, keep in mind the basic principles of its operation. The water/methanol charge soaks up ambient/absorbed heat from the intake charge in order to create cooler, denser air for the engine to burn (exact same overall principle of the intercooler). This method functions great; the side effect is that water does to some extent stall the interal cylinder combustion. If you are running too much, the gain from the denser air will be cancelled (and possibly overrun) with an excess of water. You will see the most power gains with a moderate proportional flow of water to fuel and air.

My system has the capacity to provide FAR more flow than is needed for 6 liters of displacement at 30 lbs of boost. Even the stock two stage system (before it was modified to 4) was too much, if the pressures were maxed out. My 4 stage has to be very carefully tuned and mixed to keep from either stalling the motor or blowing it up----dejavu

thank you very much for all the info. i think i uderstand what you are saying.ive turn the low end down till the engine started to studer then up two pounds the high end ive turned all the way. there is a niticable difference with the water. i didnt really measure the amounts of water per washer fluid. its about 50/50 but the washer fluid i bought had alcohol in it as wel as methanol.. i still think its worth the $$$.
thanks agin for the info

Just make sure you never have over 40/60 mix methanol/water or BOOM!
