want to make a IC sprayer. but dont want anymore switches. i was thinking on using the momentary **** for the rear spray/wiper. i dont need two modes to wash the rear window.

is that **** programed or do they use realys to move the rear wiper/sprayer? if i could move the signal wires to make it spray onto the IC that would be great. i would splice in a hose to whats there already.

do able?

 

im just thinking of it in a different aspect.


if you want that switch to cover both the rear and the IC spray. you would need 2 different pumps with solenoids, other wise if you just splice a hose they will both get liquid.


I would imagine they are different circuits since they are two different contact points.


I definently like the idea

 

Most folks just deactivate the rear sprayer....
And reroute the hose...often with a wiper delete or due to a rear sprayer clog due to corrosion...
The tank is tiny...it worked...but the activation was a pain....
Heck the Alta diverter was even plumbed with a sprayer to be installed this way...

 

If you don't already have xenon's with headlight washers then my recommendation would be to source a used headlight washer tank with pump and add hoses with a nozzle to spray the IC.

Sure you would need to somehow incorporate another switch but get creative with switch location and it won't be as noticeable.

Two idea's for switch location:

1) Have a pedal depressor switch under gas pedal and it only sprays (automatically) whenever you fully depress the gas pedal. Similar to a kick-down switch on gas pedals on cars w/automatic transmissions.

2) Source up a steering wheel paddle shifter and make that be your IC switch. That'd be cool too!

 

Having done this mod, I would only add that you keep the container empty during colder months to prevent the tank from freezing/splitting. Would also be good idea to mark the top filler cap so a tech doesn't top it off with windshield washer fluid if using straight H2o.

 

Wonder if this mod contributed to those knarley corroded injectors you took out when you converted to the jcw380's.....
One vote for the compressed co2 cryo system...that system is neat!! Still have it?

 

Yeah those gnarly looking injectors were pretty bad huh , but no I didn't have a sprayer at that time...

CRYo2 Sprayer is still in. Matter fact just hooked up the tank today since it was out for some body shop work. Inskip replaced my LR quarter panel under extended rust warranty ( rust below tail light ). They do nice work as it's not easy blending in a new panel to existing metallic paint.


Took this shot recently. Wonder what would happen if I sprayed water onto the IC first then shot it with CRYo2 ?

What about using something like a Howerton meth injection system?

What are the benefits of spraying the intercooler to cool the charge vs injecting methanol to cool the charge?

 

well spraying the intercooler, will cool the intercooler, usually the water/meth injection is post intercooler, theoretically you could do both


spraying the intercooler, will keep those temps down, whereas water/meth evaporates in the intake cooling the intake charge,


if done properly, you don't need an intercooler if the water/meth injection is good enough

 

There is a micro switch on my pedal which is set to activate when pedal is fully pressed for WOT runs dumping CRYo2 onto IC. There is also a manual button SPST to cure heat soak.

I also insulated the upper radiator hose. That thing sends a ton of heat to the IC especially when sitting. I covered the hose with 3 inch pipe insulation from Home Depot. Then quick tied it around the hose, and fabricated a heat shield to keep any additional heat down. Now when parked for 30 mins in the store, IC temps are way lower and more manageable....

One of the cheapest and best heat management control devices I have come up with so far...and I had all the parts in my garage....hahaha.

In these photos, the rubber seal around the front wall was removed just to show what was done. It is back in place.

 

GrayRaven--
I am going to use your mod as a template and do the same thing to mine. Heat soak in stop/go traffic is a biatch here in the land of Sunshine and Bromides. Anything I can do to keep that intercooler from heating up will help....

Thanks for the good pics and idea!

Cooling intake charge with water or water/meth is all about the fluid being sprayed inside being atomized finely enough to evaporate. Evaporation is what draws the heat out of the air. Atomization takes good nozzles and a fair amount of pressure to blast the liquid into enough small pieces to make the surface area to mass ratio as high as possible, because after all is said and done, evaporation is *all about* surface area....

Pulled this topic up while the spring months are here and looking into various cooling options. I like the simple insulation of the radiator hose. Looking at adding that, but also curious about the heat plate in the photos. Was that custom built as well? Help direct airflow?

Thank you

 

That heat shield is custom built. and its not to direct air flow, but to keep the radiating heat from the radiator hose @ 200 deg F making its way to the IC

 

Great, thank you for the quick reply. I'm guessing a simple galvanized sheet metal?

 

Looks like aluminum to me

 

Aluminum was my first guest. But unless coated, it will corrode. I'll look into some options. Thanks guys
