Solenoids trigger at the same time as the pump or what?

Turbo-Geist

I believe my solenoid is powered by the same wire that powers the pump. When the pump is on, the solenoid is energized. I also have an led tied into this wire to prove it's getting power.

Interesting setup for sure.

Very..

No, nothing Steven said.... I said "I" was suspecting there would be little benefit from breaking out the IAT and was thinking there would be little difference in the temps when it's so cold to begin with. After giving it thought, I agree with you. I'm still not breaking out my IAT though. Totally trust Steven and he said don't bother at my level of power (9psi).

Yes you would want them to trigger at the same time.

NX, what nozzles are you using for a DP meth setup?

Now this is a nice set up.... !

Nitrous Express & Snow Performance

We have 6 different sizes of nozzles, numbered 1-6, higher number flow more water/methanol. On most applications you will only need a #1 or #2 nozzle in a direct port system. The nozzles are 1/8" NPT so they thread in very similar to what a nitrous nozzle would but the spray pattern is different to mist the water methanol.

Can you post better pictures of the nozzle placement as well as how it looks from the inside?

Recently did a car that worked out great. Single m5 before intercooler and single m10 on outlet of intercooler. Works great for a meth heavy setup.

Before I pulled my blower to go twin turbo I was running a 5 in the YSI inlet pipe and two 15's in the charge pipe to the throttle body.


I like the idea of direct port but I am concerned about a small nozzle getting clogged, you would basically have a 3gph nozzle in each cylinder. Since most of us cannot log EGT's, you wouldn't know till that cylinder was melted down.

Im planning to at the very least weld bungs to the charge pipe this time around and screw in nozzles vs using the rubber gaskets.

FWIW, I wound up breaking out my IAT and welded the bung same side (top side) as the ITA directly inline with the meth nozzle about 4 inches apart. I have a deluxe OBDII scanner and can read the IAT live.
I confirm the IAT drops instantly at any RPM with this set up.
Julio at Alky Control is the one who advised me that this was the most effective placement of the nozzle/IAT setup. He was right. I see so many guys placing the two nozzles opposite from each other on the charge tube however, I feel with the velocity of the charge tube, the meth never makes it across the charge tube to read the temp drop. Maybe it does (who knows)?

Unreal

Works fine for me. Reads a great temp drop.

Its the vaporization and pulling the heat out of the intake charge through the vaporization that should effect IATs, not the temp of the liquid being sprayed in. Liquid meth should not be getting to the manifold or IAT.

imxz28

I would generally agree with you however, this video is actually what inspired me to start this thread. He holds his had at least 4 inches away from the nozzle and I see a lot of liquid that has not vaporized yet. I would imaging in a high velocity charge tube where temps are higher that vaporization would occur quicker but believe there will still be raw liquid 4 inches from the meth nozzle. Just spawns the thoughts of thermal and fluid dynamics in the charge tube and intake runners.
My main concern would be the raw fluid flying past the front intake runners and accumulate more on the rearward ones. Not trying to start a debate, just sharing where my thoughts lead.

My nozzle is a good foot before the throttle body on the bottom of the charge tube. IAT sensor is after the TB, screwed into side of intake. Still picks up the drop just fine. It doesn't drop 100* or anything but it's not unusual to see 20-30* under ambient

Probably just depends how much you're spraying. If you saw how much an Alky kit sprays while in boost you'd probably be surprised. It is quite a bit... it's not just misting a little out..

I think this is the way to do it, just put the nozzles as far back from TB as you can, when I spoke with Julio he was surprised so many guys put it right in front of the TB

neverstop

what was the thinking of putting it before the intercooler relative to putting it other places?


I've heard of guys spraying pre compressor to try and get more out of small turbos etc but haven't heard of that placement

schpenxel

Yeah, I think so too. I wanted it to have as much time as possible post intercooler to do it's thing. I wouldn't want to run it right at the TB either

Unreal

Just move it forward, and help cool off the intercooler at the same time.

I don't buy spraying into air is representive of how meth acts in the intake tract.
