DIY IC Spray for under $10!

[ping]

Sheesh guys this one's EASY!!! The total electricals necessary to run the "wiper motor off while spraying the intercooler" would cost maybe $12 if you include a fancy $10 switch... just need a length of wire and a switch:

1) Find the power wire to the wiper motor
2) Cut said power wire, splice in a couple feet of decent gauge wire (using the same color gets major props)
3) Run the now-extended power into the passenger compartment and attach it to a toggle switch. What the heck, be fancy and use one of those "covered" switches with the flip cover. Position it such that the switch is "on" (completes the circuit) when the cover is down, and can only be switched to "break" the circuit after the cover has been flipped up..
4) Run a wire from the OTHER terminal of the switch back to the cut wire near the wiper motor.

THAT'S IT! That way, leaving the switch cover down (switch in the "completed circuit" mode) means the wipers work normally. Flipping the cover up and turning the switch "on" (meaning breaking the wiper motor circuit) turns "on" the intercooler spray and turns off the wipers.

If'n you want to get REALLY fancy, hook up a soleniod valve so the same switch also diverts the fluid...

Oh - using the back left (passenger side) of the engine compartment for a water bottle/sprayer may be counter-productive - that's where the exhaust heat will be hottest. Better place to mount would be where the cone filter goes on a CAI, or on the other side... somewhere outside the heated zone.

Ironically, for the same reason that would be the best place to mount the washer fluid bottle to install headlight washers... that's another project on my list...

Ping, like I said, I know how to splice wires & that's about it. If there is any way that you could write up a How-To for this part & maybe even include some basic pictures, that would be awesome. I know that a lot of people are hesitant to try something unless they can see it & read an explanation. That's why I go into great detail with all my How-Tos & try to take pics everytime.

Don't do this! All you have done by your instructions is essentially put a circuit breaker to the wipers, and if you follow your instructions to the T you have also disabled the washer resevoir. The washer resevoir is powered by the wipers, so what good are you doing? Now you could find a switch that in one position connects the 12VDC to the wipers, and then cut pin E wire off the wiper switch (wire to the washer motor) that shorts to the same 12V in the other position (thus opening the circuit to the wipers), but why is that necessary? If you cut the wire to pin E then the pump is no longer affiliated with the wipers. Why put another switch to the wipers??

Here is a quick how-to:

-Cut wire that attaches to pin E of the wiper switch connector (if you don't know what wire that is just look at the diagram in the document black majik posted earlier in this thread).

-Second, use a multimeter to find out what wire on the wiper switch connector supplies a constant 12VDC when the ignition is in the ON position.

-Third, get another piece of wire that is long enough to reach where you want to put the switch (for the water sprayer) from the wiper switch connector.

-fourth, splice into the wire that you found in second step to the wire you got in third step (you don't need to cut the wires just peel off a section of the shielding on the constant 12VDC wire and run the wire from third step between strands and either solder or just twist around).

-fifth, go get a double pole single throw switch (momentary if you like) from radio shack. This is a basic switch that has two connections and one position connects the two connections and the other position opens the circuit (disconnects). All momentary does is the switch only remains closed (connected) as long as you hold it there and then it automatically returns to the off (open) position.

-sixth, connect the other end of the wire you spliced into the power wire in step four to one connection on the switch.

-seventh, connect the wire you cut from pin E of the wiper switch (the one that goes to the washer pump) to the other connection on the switch (you may need more wire depending on where you mounted the switch).

Make sure to insulate all of your spices with heat shrink or electrical tape.

Now you have separate switches for your wipers and your IC sprayer (neither will activate or deactivate the other).

This is the best I will do until I make my own IC sprayer, which I will not be doing till I get the turbohoses SMIC (which has not come out yet). I will take pics when do make it and put up a how-to, but if you don't want to wait these instructions are not too hard to follow.

how much of a difference are you guys feeling after spraying? I dumped tons of water on my ic right before I went against my buddies beem and it really didnt seem to help much, maybe because its not crazy hot here to begin with, but i was disapointed with the end results. (uhm)

My setup is a bit different. I pulled a washer motor from a junkyard and basically just have it wired up to a switch in the cabin. I didnt end up using those nice nozzles, instead I put a "Y" fitting on the end of the hose and sorta cut up the ends so it sprays more of a V pattern out of each end of the Y. I can see that its all hitting the IC, and I usually go for a little boot after spraying to see if the air hitting the wet ic will cool her down a bit. Maybe its cause ive got no ice in the res but im not sure of how effective this is anymore, and people keeping giving me funny looks when they see my car peeing at the lights lol

I can't tell from your description, but my nozzles are misters. The purpose of the H20 sprayer is to lower the ambient temp of the air going into the SMIC. If you are using something like like BlkZoomZoom's C02 sprayer, cooling the entire SMIC WILL yield results. However, with water, you just want a mist...I think that pouring water over it or spraying water into it (in a stream, not a mist) in neither helpful or a good idea.

 

[jeffmsp]

sounds good I will have to go pick up some nozzles. Right now it is pretty much just shooting two streams of water onto the IC, i will try the mist and tell you how it works out (thumb)

Well i was going to try to do this setup..and bought some of the parts..but the thing is i just purchased a nitrous bottle..so i will be doing a Co2 setup instead!

Thanks for all the info!

Chas

P.S. this needs to be moved to the HOW TO SECTION!

 

[lncatch]

sounds sweet, but i got one qustions, what if you just used super compressed air?? would that work the same basically cuz im pretty sure compressed air is cold, i could be wrong tho

Na..that' won't work..my last job was in a mechanic shop..and i used lots of air toolz...and that air is def not that cold..

Nitrous & CO2 Are both freezin like -40degree. Just a quick shot as i get to the line..will be more than enough for a full run! I don't really think there is a need to keep shooting through out the run.

Has anyone tried the CO2/H2O combo setup? I imagine spraying water on the IC and then freezing it or dramatically cooling it with the CO2 sprayer would create a longer lasting cooling effect.

Ya, imagine a nice layer of ice on the front of the IC, that would be mint. To bad it probobly wouldnt happen, but meh.

 

[lncatch]

co2 stuff would be easy to do, anyone kno how much co2 refills are and where you can get them...i looked around and there doenst seem to be anywhere that does it

 

[acidbug]

Yeah..there's a place in NJ..the town is old bridge, NJ...

The cost to fill up a 2-3lb bottle is like 3-4bucks..it's really cheap in comparrison..to how much nitrous cost (~4-5bucks per lb)

Chas

 

[lncatch]

you don't need a compressor, right, bottle pressure will push the co2 out?

 

[acidbug]

Just a bottle..Like this one i just picked up!

 

[lncatch]

wrd, that bottle looks like it lasts for like one shot

 

[acidbug]

wrd, that bottle looks like it lasts for like one shot

actually this bottle is used in the sneaky pete setups..and from what i hear..w/ a 35 shot..this bottle will last you 1 run.

So i figure it should be enough to do a 3 quick shots worth.

I apologize if my posts seem a little random...I'm going on little sleep & I'm busy with school.

Rick: The next time you're at one of the meets, I'll give you a demonstration. I really like the setup because without removing the grille, it's almost impossible to even tell it's there. The only thing you can really see are the vales & the are flush up against the side & underneath this lip.

Jersey: I've tried it out a few times so far during spirited driving. I wasn't expecting to feel anything like hitting a NOS button in 2F2F, but all I can say is that my car was still running great despite it being like 90 degrees out. I still need to try using colder water to see a bigger improvement.

The ONLY thing I have left to do is figure out how to disable the wipers from going off when I pull the wiper stalk to mist. I thought I read that you can just take out a fuse, but I didn't look into it. If anyone knows, please share the secret.

Just unplug the motor..... I've been driving ever since I got my car with it unpluged... The motor is right behind the battery and a little up... there's a little white plug, just pull it out... wipers will never come on...(cool)

Hope it doesn't rain...
