meth nozzle flow?

They're cone-shaped impingement nozzles. That's not a garden hose, it's a pressure washer hose at 1000 PSI.

While its going you can wave your hand 4" from the nozzle and not feel the water impacting your skin, but your hand comes away soaked. I don't think the "atomization" is sub-par in the slightest, but maybe there's some other feature of nozzle design I'm not aware of. I wouldn't imagine that pattern alone is that big of a problem, especially not when nobody says that it's critical to align the fan nozzles perpendicular to air flow (or do they?).

My leading theories are... that injecting into a stock 1" square non-intercooled first gen intake horn causes water to pool all over and form droplets that take forever to disperse... that it's what you get when you inject water into a 400,000 mile engine... that there just aren't that many people running 1000 PSI over the course of minutes...

Maybe one day I'll use some of the off-the-shelf nozzles that everybody else uses, that'll eliminate my nozzles from suspicion or condemn them. I should have my truck up and running within a couple weeks, hopefully I'll have my new datalogger up within a couple month, I'll just keep rehashing my milkshake woes until I have some additional data.


At any rate, of course there's a point where too much nozzle will cause the water injection pumps to drop pressure and you'll get worse atomization. I believe they say that's around with two of their "625" nozzles? I'd hope somebody knows. Regardless, they seem to work beyond that.

I don't know, too many people using the kits as straight bolt-ons, not enough experimentation with them.

Im running one snow 625 and a devils own 8xx, off 1 snow pump. Seems to spray fine, and isn't doing my oil any harm.

[You must have a real long hose, do other cars tend to run it over when you drive?:stab:[/QUOTE]

:lolly:
 
So,...is the intake pipe you have it plumbed into 4+ in diamater? If not it seems like that would cause an issues with droplets

Me? Just plumbed into the top of stock intake horn. But I haave it set very progressive where it doesn't spray 100% until over 25psi

Good call.

Nope he was talking to Begle, and I immediately saw his point.
 
^ yep thanks.

Plus even if you have a 5" pipe if the injector protrudes more the. An inch or so it will be far less then 4" to the sides of the pipe.
 
Anyone ever trying plumbing them in at an angle so they spray down the tube instead of directly at the far side?

I was thinking about that, but more in like a direct port setup. I think 6 or 8 100-150cc nozzles would yeild better results then one or 2 large nozzles of = flow. And it seems like it wouldn't be terribly hard in a cummins setup

Has anybody ever ran a "625" or "1000" mL nozzle in a bucket for a minute and seen how much they actually flowed?

(2) 625'S AT 190 psi flow 1/2 gal per minute with zero boost ( in a bucket) tested this like 7 years ago, sorry I fell behind on posts :)

Never factored in boost,... Makes sense though 200psi pushing against 50psi I'm sure makes a different.
 
Probably a good idea to check nozzle flow to compare apples to apples. I'm dealing with a much smaller application than you guys but through some rough testing I found out that what I bought as a 250cc nozzle was more like 380cc. I couldn't figure out why my EGTs were higher with a 180cc and a 90cc (270 total) than with a single 250cc.
