Hmmm. The nozzle was connected with plastic lines, through a plastic pump head, to a plastic bottle.

Then it's worthless. You will have the same amount of flow at redline at 16 PSI with a partially clogged nozzle as you will with a perfectly good nozzle at low load. The controller needs to be able to read actual flow so it can compare it to predicted flow.

brass + stainless + methanol + water = obscure forms of fuel cell?

you have two metals of somewhat different nobility.... i'm just sayin, maybe the effect is just plain funkadelic.

Interesting.

Still and all, the exact mechanism of action is less important to me than the fact that with pure water, I won't have to worry about this anymore.

Anybody in SW Florida want a nearly full 5 gallon jug of VP M1 Methanol?

so your saying the shit just came unglued on him and collapsed under the pressure sounds viable to me. Atleast more viable than his desintigration theory if that where the case then the part of the screen that was embebed into other matrial would still be intact imo.
And as for icant55 yes methanol and all its toxicity feels cooler on the skin and can drop relative temp faster but water has more capacity per liter to store heat energy and is therefore more effecient + stable. I dont know if you have noticed but unless methanol is stored in a seriusly air tight container it tends to evaporate rather quickly even if kept chilled. Mix it with some h20 and it stays put alot better though.

No part of the screen is embedded into any other material. The screen is a discrete component that is slipped over the end of the brass portion of the nozzle back and retained by a little ridge in the brass.

my mistake then your pic makes it look dif though.

**Joe Perez** · 08-08-2009, 01:50 AM

No, the knurled section was just to give you something to hold onto while you thread that part into the base. On the new nozzle there's a hex section you use to screw the two parts together, but the old nozzle is a slightly different design which does not have the hexagonal section below the screen. The screen ended just below the raised and knurled section.

Also, the screen itself was identical to the new one- a fine square weave, not a coarse diagonal one.

Nope, the box is adjustable, you set the flow rate at which the output goes high. The box does read actual flow. There is an optional flow display as well.

So I checked my nozzle this morning. I have only run about two gallons of washer fluid (0 deg F) through this one so it does not have much use on it yet. It is a Devil's Own external mount.

Thymer, I think Joe's point is still valid. If the output on the Labonte box is a switched high based on a flow rate set point, then for a progressive system, where do you set it? The flow display would be useful since one would know for example that it should flow x amount at 100% DC, boost pressure aside (delta-p).

It says though that it also has a 0-5V output that is flow proportional. That would be nice to have. I sure would like to know what flow meter they have in there. I'm guessing it is a paddle wheel or a turbine wheel.

thymer · 08-08-2009, 12:54 PM

Well I suppose one could fab a comparator circuit inputting the flow meter and motor control signals. Seems a little bit overkill though. I use the flow display from the controller for a visual and the labonte as a backup. Check the injector every once in while and I think I'll be OK.

devilsown · 08-10-2009, 12:08 PM

I have not see a filter come off a nozzle like that yet. I would just put it as a fluke or bad screen.

I am not a big fan of flow detection devices. IMO most all of them react slow. You would be best off using a wide band or installing an IAT "i don't believe you ahve one from the factory" Whens the last time you saw a flow sensor for the fuel system of your car to monitor when a injector goes bad?

People are always bugging me. "when you going to make a flow detection device like the others" DevilsOwn has no plans atm to do so. There is one flow sensor on the market that someone else sells i don't think i would be able to sleep at night if i sold it.

Please do share with us. Which one and why you feel this way.

Anyone else having problems viewing the pics?

magnamx-5 · 08-23-2009, 12:47 AM

nope works for me but rick said the gallery feature would bug some of the pics.

**Joe Perez** · 08-23-2009, 09:58 AM

All of my pictures are hosted via external sites (imagefra.me and imageshack.us) rather than here on the forum.

Dust · 08-24-2009, 07:02 AM

Works now. The OP's pics weren't loading. Those look like a McMastr carr nozzle I got. THe screen was wrapped around, but came undone. It's been in the bag-o-fittings since.

Dust · 09-12-2009, 03:19 AM

I just took out my preturbo nozzle, which was mounted right next to the BOV recirculation point, and my nozzle was filled with gunk from the valve cover, and wasn't spraying at all. Gotta clean it up

MSMjohn · 10-01-2009, 11:38 PM

Took mine apart after about a year & the nozzle, screen, passages & everything looked fine.
