How come your IC had water puddling if u injecting post the IC?

Maybe its the angle of the chamber there as the spray direction is more facing the I/C or incoming air ?

Were is mounted it

I think he is pointing out that the nozzle in under vacuum. With a clogged check valve, the engine is siphoning out the water/methanol while running.
This would not be a spraying issue.

any updates on your install skratch77????

i installed a meth kit oh hadilaw's car this past weekend. it was a devils own stage 1 kit, initial results seem promising. Ambient 91 105mph iat was 104F. Still have to wokr out the kinks in the system will keep you all updated

Have anyone ever thought about relocate the AIT sensor? I'm thinking about moving the AIT sensor into the surge tank. That way I can run two meth nozzle right on the elbows of the surge tanks. Just a thought!

where did u mount the nozzle? And what problems or "kinks" are u having?

same place as sneakyneon. when i say kink i mean loose electrical connections and improper routing of the hose.

What are you guys think about the placement of nozzles like in the picuture

1 position #10 nozzle
2 position #10 nozzle

My kit will be here next week, and I am really trying to figure out all the "Math".. There is great info here, and the DIY is awesome. Not sure how I will do it, but Ill post up when I get started

Worth the wait

Which kit did you go with? Separate tank or WW tank? Nozzle placement and size?

GD man, we need details!

Good luck!

Devils own stage one, changed to stage two, single nozzle, changed to dual nozzle, added solenoid, and 2.5G tank (trunk).. and a bunch of misc jets.. I have no idea what I am doing, so I will probably duct tape to my hood

In terms of nozzle placement, I will either go where Shardul and sneakyneon went, or go on either side of the pressure tank (Facing each other).. nozzle size will be "10", or 2 that add up to 10. I have not quite figured out the numbers, but I will have the calculations completed by then to make sure I am flowing the correct amount based on actual fuel delivery. It is a complex equation, as many will attest too

I am going to go a little different from Shardul, as he opted for no controller as he doesn’t want to spray until on more boost. Since IAT’s are progresive, and this motor makes heat when off, I want to start spraying at low (3lb-5lb)boost, so that when I get up to higher boost, the IAT’s have already been assisted. I know this will be trial and error, however I think I will get it. My goal is IAT control. I am not planning to tune into the meth. That may change, but for now, it is simply to cool.

The biggest problem for us is that we have to mount our nozzles under the S/C. That means that changing things once installed in a *****. An electronic variable nozzle would be awesome, because you can only control flow so much with pressure (per jet size), and atomization is a must. Too low of flow would adversely affect that imho. One last thing:

I would think a 10 is more than enough, two #10s (spezi81) is overkill and will most likely cost you power.
I have all the parts, just waiting for the time to install.

I went with both locations (more or less) the one pre IC is facing the IC core not pointing side on. 0.8mm jet each. Location 2 seems to be the most popular although it seems very close to the IAT sensor... makes me worry about getting consistent temp readings, with not enough space / time to get a good mix/swirl of the water/air.

I will only run one of the jets I think ... so IAT's (and their consistency) will dictate which is best. At mom only running water, which apparently is supposed to be better for in cylinder cooling while meth is better for inlet tract cooling. So water meth may be better suited to pos 1, while water to pos 2. High Meth ratio at pos 1 will have fully vaporised by the time you reach the IAT so no wetbulb issues there I would not think.

Moving IAT sensor / MAP sensor is pretty dagerous given thats what ECU uses them for air flow / density calc's ... changing position will alter what the ECU sees and works off dramatically.

Still trying to work out how the IAT sensor / ECU will respond to a wetbulb reading vs dry ... it should show a cooler reading than what is otherwise expected I think.

Any ideas and info welcome...
