Water Meth tuning questions

[gear jammer 91"]

I can't get control of my EGT's to save my life. I just installed a water meth kit this afternoon and wile there is a power increase I can still hit 1400 degrees on the pyro. ( witch is a hundred degrees hotter than it was before. . . I thought ) The kit I got is from devils own, it has the shure flow pump and I'm runnin a 30/70 mix of methanol and water. The squirter is the largest one that came with the kit according to the number on it it's a 014. What I am curios about is whether that is a large squirt or if I should just go bigger and how will I know when it is to big? Thanks for the help in advance I need all I can get.

The methanol in the water doesn't really help EGT's that much...

But still, making the same power as you were before, how are your EGT's?

As far as I can tell, nobody even gets close to giving our trucks enough water... I got three fogger nozzles on the way, the smallest is a ~6GPH and the largest is a ~26GPH... I'll see how those work by the end of the week...

My egt's climb slower but they still get up to 1400 degrees. I can tell that their is power increase, the egt's just didn't get any cooler overall. I noticed on my way home today that the w/m was not turning on at all, I popped the hood to find the boost air line that goes into the pressure switch had blown off. I don't know if their had been an air leak at the switch before the line blew off or not but it now has the proper compression fitting on it. Also does anybody know if it is safe to turn the presure up on the pump?, and how much?, and how to tell how much you turned it up? Thanks.

I just looked on the website I got my kit from and the injector I'm runnin is a 14 GPH squirter. That seams like a lot to me, hopefully that boost hose was leaking and everything will work better know.

If water injection is giving you an extra 50 horsepower, but you still have the same exhaust gas temperatures as before...

If you didn't put the pedal in as far, wouldn't you be making as much power as before while having lower exhaust gas temperatures?

Now that I have some more seat time with the w/m I have noticed that my egt's are a lot easier to control, and I do have more power with less throttle. I am going to locate and try a bigger sguirter to see if I can get my max egt's to stay below 1300. Of course if I can do that I'll have to turn the fuel screw the rest of the way back in and see how fast it'll go.

Do a search for "Misting & High-Pressure Spray Nozzles".

For $4.00 they have the fittings with holes in them that Cooling Mist sells for $22.00, for $22.00 they have "fogger nozzles" that I'm going to experiment with soon. For $235 they sell "atomizers" that take a pneumatic input to really atomize things...

wow, im really digin that site

That is what the nozzels I need look like. The o-ring is were the water line goes in, and the other end threads into my intake tube. I'm having a hard time findin these that'll fow more than 14 gph witch just ain't enough.

get a splitter and add more nozzles. most guys run different sizes together to get the tune up correct.

You might want to consider lowering the percentage of methanol used if temp reductions are what you're after. The higher the concentration of meth, the higher the temps get, but you get more power. I read somewhere that a mix of 85/15 or 90/10 water/meth yields the greatest temp. reductions (better than straight water).

I might add a second nozzle here pretty soon. The kit I bought came with three and the company I bought it from does make smaller squirter's so there is a lot of tuning ability with two nozzles, I was just hoping that one would be enough. My reservoir right now is 1/4, 70% water, 30% meth, and 3/4 water. I hooked up a light 3K pound camp trailer today, with that mix I stood on it from a dead stop and ran up to 60 at full throttle through the gears and my egt's stayed under 1100 degrees. So it looks like I just need to do some carefull mixing and have one mix for towing and one for power, or add a another squirter, mix for power and go for broke.
