Does anyone have the down low on an automatic IC sprayer. What I am looking for is something that can read intake temps and spray accordingly. I can come up with the resevoir and pump. I would like to find something that would run the relays off an intake temp sensor.
Or
What I would need to put together a system of my own.

All you'd need is a temperature switch that will activate at a certain temp, and possibly put that in line with a relay which will then turn on the pump.

why not just use water injection, as in into the air stream and not outside of it

You could make something fairly easy, or if you have an eprom ECU, I could make a chip that will actuate an output(like EGR or Purge) based on IAT(or anything else).

how about making something that can be used on 1g as well as 2g cars.. a single product.. now that would be something better...

Come to think of it, you'd probably want to add another IAT sensor, preferably in the upper IC pipe.Using the existing IAT would be pointless.

yeah ive considered this product before and talked to a guy in cali and a local friend who would both develop it - use an IAT in the IC outlet and tap into the TPS as well, when IAT is over a certain temp or TPS is > 70%, give the sprayers power. would have to have a window on the temp, turn on over x temp and turn off under y temp. we were going to do it with a little microcontroller, or alternatively an adaptation of the zeitronix TCAC (throttle controlled A/C, which does the TPS portion of the job already).
would be cool and i'll eventually do it. i have 2 questions though - do you think you'd have to spray enough water that it'd be wise to have an accumulator, and can dsm fuel pumps run long-term in water? i read a post a long time ago saying the fuel pump was lubricated by the fuel it pumped so it wouldn't work long term in water, but i don't remember at all who said it or if they knew shit about it

I could whip it up in less than a 1/2 hour with a microcontroller.
I would say using a fuel pump is a bad idea.

I would use a second sensor for the cooler. It is a cool idea about using the ECU, but I want to keep it simpler. My ideal setup would consist of
sprayer nozzel (green house scavanged)
water resivor (junk yard scavanged)
pump (jys)
intake sensor (?)
relay to run (?)
override switch
I would prefer it be a stand alone setup. It easier to figure out what wrong if theres less to it.

Do you guys have laptops? How about this?
I can add up to 3 more inputs for various things.You could use it for nitrous, IC spray, water injection, etc.

looks good. Are you going to make the kits also?

What do you mean by kit?
And I could pre-program the switch, if you don't have a laptop.

Shitty drawing, I haven't done a schematic capture yet.
C1= 100uF 25 volt electrolytic cap
C2= .001 uF 25 volt ceramic caps
C3= 10uF 25 volt electrolytic cap
C4= .01 uF 25 volt ceramic caps
D1 and D2= 5.1 volt zener diodes
R2= 2.2k 1/4 watt resistor
R3 and R4= 1k 1/4 watt resistors
R1 = 2k 1/4 watt metal film 1% resistor
IC1= Microchip PIC12F675
ADC3 controls the relay and may need a npn darlington transistor or a p channel MOSFET(radio shack) depending on the relay used
IC1 needs to be programmed with my code, I'll do it for like $15 w/chip included.This works in my simulator, but some of the ceramic caps may need slightly different values in the actual vehicle.Everything should be available at radio shack, except for the 12F675, I have a million of these anyway.You also need a switch and a DB-9 serial plug and possibly a max233 chip depending on your computer.Total parts should be around $25-$30.I can program the temp and tps values when I burn the chip or you can give me a little $$$ and I'll give you the above software.

damn dude, i could have really used some mad electronic skills like that in my physics 131 lab today!

that would be excellent, i'll start researching pumps and fuel pump lubrication. free source of pumps would be killer.

i bought a pump from these guys awhile ago
pumps
i was recommended them by a few other guys who have made their own water injection systems. if my car ever runs right i'll start putting that onto as i have all the parts just sitting around.

Are you guys talking about water injection or IC sprayers?

i'm pretty sure they are all talking about sprayers, sans me

A cheap inline windshield washer pump will work in that case.You don't need much pressure or volume.
