How much water?

[Timthetoolman]

Water Injection system.

I have my 100 PSI Shurflo pump, PSI switch, water solonid, and I have two 10GPH mist orifices.

I gonna put this baby on this weekend, mounting the two jets into the intake hat on each side. I am gonna put a shut off valve on one water jet so I can run one or both, QUESTION, how will I know if I am putting too much water into the engine, what will it do, how will it act?

What do you guys run for water, Walmart washer fluid? I was thinking of using water and 20% Heet additive.

Too much water and you'll hydrolock that engine. For water injection it's recommended a 50:50 mixture of water and methanol (HEET in the yellow bottle).

What is the rate for the nozzle again? And what are you using for a pressure sensing switch? Is it a Hobbs-style switch?

I would recommend running one nozzle at the lowest setting and keep an eye on your pyro temps, see if they drop when you have the system on.

I have a PSI switch from NAPA and I set it at 6 PSI of boost.

The water solenoid from McMaster Carr.

The mister is a 10GPH.

The Pump is 100PSI.

I figured I would start with one nozzle then add if EGT's are not in range.

I'm not sure how many GPH mine is.
But, if you feel like doing the math,
at WOT it flows just over 40 ounces a min.
This is with boost levels up in the fifty's.
You won't be able to go through anywhere
near this amount at 6 psi. Start with one nozzle.
You'll know if your using to much.
It'll feel like you're putting the fire out.
And Yes, Walmart fluid is OK to run.
Most washer fluids are about a 75/25 mix.
And a little squirt of blue to make it look pretty.
I'm guessing that you already know you must use
washer fluid designed for winter use. Not summer bug wash.

40 oz/min x 60 min/hour = 2400 oz/hour
2400 oz/128 oz/gal = 18.75 GPH

So two 10 GPH nozzles should be right in the range....

 

[Timthetoolman]

I thought by everything I had read I was close, I hooked up the water pump on the bench and it just seemed like a lot of water.

With one nozzle I can pump 32 oz in about one minute, so I must be real close, gonna hook it up today after work, I'll take off up the mountain and see what it will do and let you guys know.

Did you read the part about "boost in the fifties"?

I can't imagine that math to be correct for a boost less than that!!!

You're going to drown the poor thing. This is going to
be Way to much to start with. 30 and 40 OZ
is suitable for high boost and 450+ horsepower levels.
If it were me? I'd start with a flow rate of about a
beer can or the equivalent of, a minute. You can always
add a bit more later if you think it's able to handle it.
Once that 30+ OZ's has gone in, you can't take it back
out if something goes horribly wrong. I'm guessing we're
dealing with 6-9 psi of boost and about 200hp in your case?
Do the math. PLEASE!! Or your next post may start with.....
I blew the ****** up ,,,,now what?
It's your truck, Do what you like man.

I used a .17 gpm nozzle which is a 10gph nozzle and it was too much in my application (the Enterprise = 7.3 idi banks air stuffer). While it did add some power (windshield washer fluid) what I ended up with was star cracked pistons and a knock which we figured was a flattened wrist pin. I was running around 100psi + I'm not really sure what I was getting because I adjusted the regulator on the pump to the max which was factory set at 60psi.

So I would strongly recommend not using two nozzles.

 

[Freight_Train]

Ummmmmm,isn't that MORE than what Travis was spraying??!?!?!?!?

 

[Freight_Train]

well,guess we was typing at the same time.......When Travis says it is too much....IT IS TOO DAMN MUCH!

 

[Timthetoolman]

I hear what you guys are saying, I'm gonna start with 3GPH nozzle and go from there, all I want is to be able to run WOT, that alone will be enought power for me.

Right now I can olny run about half a peddle up long hills with my fiver. egt's at 1,100, I just want to cool off the EGT by 200 degrees.

I'll reorder some small ones and try it next weekend.

 

[rubberfish]

You have to remember that by running WOT you'll
increase egt's by hundreds of degrees. So whatever
improvements/cooling you see from injecting water/****
will be cancelled out by running WOT. It's a vicious cycle
that's hard to win, and never really ends. When the ****
kicks in, you won't see the pyro plummet 200* right away.
What you'll probably notice is the pyro will climb a little
slower, which will allow you to stay ******* the smoke pedal
for a little bit longer while enjoying some extra umph.
Again,,,, start with a little, and go up from there.

Travis has nothing but gobs of money laying around,
and no responsibilities in life either, so it was no biggie
for him and his family when his motor went BOOM.

which time? because there was once that it was a royal pain in the butt (had to walk home)... but all the other times it was nothing more than an inconvience....

 

[Timthetoolman]

Ill take the wash between the temp climb and cool limit, thats all I want, if I can hold WOT for 1-3 minutes that will get me over most all the hills here in the Mt's of East Tennessee.

My turbo gate opens at 8.5 PSI of boost

FYI, I now have a fully operating biodiesel system at home, a good supply of WVO. I can process 15 gallons at a time in my processor. I have been making small batchs and running it in my Kabota for a few months now. I haven't run any in my IDI yet, will have some in a couple of weeks, gonna run it 50/50 in the IDI.

Got my new solid mass flywheel and clutch yesterday (NAPA brand), can't wait to get it in, just dread laying on my back pulling the tranny.

Thanks for the water info guys, thanks Travis for your prior experiments.
