Water/Methanol on a JRSC non SVT

[Stolle]

alright. im sick of seeing these blistering IAT's with my JRSC.

Is it alright to spray water/meth b4 my IAT sensor which is located right after the blower itself. Ive heard that if its not fully atomized before it gets there it will instantly ruin the sensor?

[focusownerskid]

Spraying before the blower unit or in the mani next to the IAT?

spraying nothing right now and having hot as crap IAT's FTL.

[focusownerskid]

No, where are you GOING to spray it?

Before the blower will be fully atomized.

After you'll be risking false IAT reading based on the mix blowing straight onto the IAT sensor.

Once you stick that sensor after the blower and see the readings, it's pretty obvious why the JRSC is a limited power adder.

My IAT is located under my JRSC mani i will find the link on here for the pics

He already has the sensor mounted, just not the WMI.

Here is a pic of where I ran my WMI injection

Tapped into my TB. If you look closer you can see the anti syphon solenoid too

Spraying right before the IAT sensor won't really ruin it but it will cause crazy readings and spark advance maybe increased too much.

I spray before the blower on my PW kit with no ill effects. IATs drop down to ambient temps at full throttle when spraying.

[Stolle]

oooo. nice. i have a open area on my blower right b4 the rotors but after the tb. i think im gonna mount it there.

[focusownerskid]

That's where I tapped my blower for WMI.

what kit did u go with?

I had a Snow kit on mine way back when.

I think tparker bought that from me in '06 when I sold my car, then removed it when he went IC'd.

That's probably the best spot. You will need an anti-siphon solenoid if you mount it after the TB. You won't need one if you mount the nozzle before the TB but you obviously want it after the MAF. Also if you have boost gauge tubing attached to the manifold dowstream of the nozzle, make sure you arrange it so the tubing proceeds straight up for an inch or two to prevent any liquid from pooling in it. That goes for any vacuum line attached to the manifold dowstream of the nozzle. My tubing collected a drop of moisture and managed to push it into one of my MAP sensors. Luckily it was the MAP for the boost gauge and not the MAP for the ECU. I think I had sprayed by accident on a cold motor and the low under hood temps didn't evaporate the liquid before it did its evil deed.

If you adjust your tune to take advantage of WMI make damn sure you have an empty reservoir light mounted in a prominent location that will get your attention. A fellow I work with blew up his 1200 lb/ft diesel truck three weeks ago because his 7 gallon reservoir ran dry and he wasn't paying attention to the big red light on his EGT gauge telling him to back off. If you really want to be safe about it, buy a Snow SafeInjection box and a J&S Safegaurd. Those will work in concert to prevent any engine damage if the WMI pump fails of the reservoir runs dry.

what size nozzle should i use?

im running stock crank pully with the non svt BBK.

[DigitalGT]

Probably a 100 mL/min which is the black nozzle. The yellow one is 60 mL/min which is a touch too small. The green is a 175 mL/min which is probably too big. It all depends on then engine and which controller you use. There are some guidelines for anticipated horsepower -vs- nozzle size but they are only rules of thumb.

All of the nozzle ratings are at 60 psi pump pressure. If you use a progressive controller like the Stage II MAF and peg it to the max pump pressure of 150 psi, you'll see about 50% more flow from whatever nozzle you have installed. So the black nozzle that flows 100mL/min at 60 psi will flow 150 mL/min at 150 psi.....roughly.

Only tuning will tell what you need. The Stage II kit I bought came with 2 nozzles I got the black 100mL/min and the green 175 mL/min nozzles. If I had your setup, I would order those with the kit. I highly doubt you'll need the little yellow one. You'll most likely wind up using the black nozzle.

[kennan J]

Yeah I would go with the black. You have the zetec kit. Im running the green nozzle it should work fine for you

[Stolle]

so im looking at CFM right now. so i would go with the stage 1 kit with a 100ml nozzle with a solinoid upgrade because im gonna mount it after the TB.

[kennan J]

good deal you may want to think about adding the 7 quart tank just because of space issues. The larger tank will come with more tubing also. i can post you a pic of my tank/pump location

[Stolle]

just give the pump igition power and ground then? and plumb the tubing with the solinoid inline up to the engine where ever im going to mount the nozzle after tht TB?

give the solinoid power and ground too?

[kennan J]

I have an on/off switch for my pump, and the solenoid is connected to ground and ignition power. My line is ran under the car and through the engine bay the instructions to kit and solenoid upgrade will have better instructions for wiring than what i just gave lol

[Stolle]

how far away from the tank or nozzle should the solinoid be? by the nozzle? or the tank? im thinking closer to the nozzle under the hood because then i have like 9ft of fluid still in the line if its in the trunk to get sucked into the manifold...

[kennan J]

you got it i have another pic of the solenoid its right under the nozzle that goes to my TB if you scroll up to the pic of my TB you can see the solenoid, it has a bolt on the bottom of it. there is an in and out hose

[Stolle]

since i have a hard piping intake on my JRSC could i just tap the pipe and spray b4 the TB and avoid the need of the solinoid?

[DigitalGT]

Yeah no problem with that. Just make sure it's close to the TB and far away from the MAF.

I only placed mine after the TB because I had a convenient spot for it and I wanted the spray to pass the least number of obstacles before it reached the combustion chambers.

[Stolle]

true. i thought about that right after i posted that. think it will matter that much?
