Liquid cooled throttle body, test phase one completed.
 

Well after getting the idea on this thread here http://www.7thgencivic.com/forums/sh...208122&page=23 I decided I had to see if it would work. Well it does, but.....
The water didn't stay cold long, if I filled the whole container with ice it may have helped but I gave up after a few and just poured some chilled water in there. The damn kneck is so skinny it's hard to fit ice cubes down there. Crushed ice would be best. When I tested the system in my garage it made the throttle body ice cold. Went out on the road seemed to pull pretty good. Drove around for a bit. Got on again and couldn't feel any loss. Turned the system on as people were probally laughing at me cause my wipers were going on a clear 90 degree day(haven't figured out that problem yet) :giggle: . Made a u turn and got on it, couldn't tell a difference. By this time the water probally wasn't ice cold cause it sure wasn't when I got home. :_disgust: So at this point test phase one was a funtional succes but not results wise as far as can tell. Maybe If i packed the resivour full of ice this would make a difference at the track. On the street with the exception of a predetermined race it would probally be useless. Still need to find some of that fuel line to wrap around the intake for phase two. Another idea popped into my head as well. Instead of liquid cooling everything why not air cool it with CO2? Not sure how CO2 works but if I could find a way to recirculate it through the throttle body and around the intake maybe that would be better? Or just drop some dry ice in the resivour? Dunno but it was fun trying something new. I'll keep at it. Need to order my odysee battery so I can do my headlight intake still, cause the filter location of tha V2 is killing my HP in this heat.

Hahaha, someone was bored. Good idea man, you just need to refine it and possibly try dry ice or something along those lines.

ya i was just gonna suggest dry ice. Its VERY cold compared to ice and lasts quite a bit in there. It will continue to cool the return water from the TB. I think thats your best bet but you need pellets. We got a machine in our lab that crushes big chunks into small pellets, but maybe you can find something like this somewhere. It would be great for the track!

as a quick fix, I'm sure there's a wiper fuse you could pull at the track so the wipers don't work.///

haha awesome. finally someone did it.

yeah I pulled the wiper fuse in the cabin but that cut the pump or what ever pushes the water as well. This was just a prototype. I guess I could find some black hose line somewhere and use that to make it look a little better. So you can put dry ice in water? I wasn't sure if you could. Cool. Maybe I'll make a trip to wally world later. Like you said I need to find away to crush it though. really need to do some testing at the track after I wrap the intake and see if there is a difference.
And yes I was bored. :) Suppose to be working on a speech for tues but I am procrastinating.
:shrug:

That's just awesome. lol. On the intake note, I know I have the 01-03 front bumper, but I cut out the spot where the left fog light would go with a dremel so more air would run directly into the spot where the filter is. It helped a little. It shouldn't be too different on the newer ones.

be very careful. dry ice in water creates bubbles (pressure) and lots of cool smoke :) But make sure that cap stays off otherwise the tank could explode. No joke.

moroso makes a contaner for super cooling the fuel system im sure it could be adapted to using water in it instead of fuel

just a thought, has anyone tried to run cold air from the a/c into the throttle boby through the intake piping??

Ac robs to much HP and u would probally lose more then u would gain(assuming there was a gain at all)

BTW this took all of about 5 min to hook up. So it could be put back to stock for use of wiper washer on the street then easily swapped back for the track. Now I just need to get some dry ice and see if it is worth it, oh and figure out the wiper issue. My friend just ragged the shit out of me when I told him what I did and how I was driving down the highway with the wipers going.:)

Ok I just took everything off cause I have some races hopefully going down tonight and I don't want people seeing that rigged setup in the event I do pop my hood. I notced the throttle body was actually quite hotter than when I intially left it sitting in the garage for the last hour or two. So I guess maybe it did work. Still could be colder with dry ice though.
Aight Im out for the eve hopfully I'll have some win stories to tell. Supposed to race an R32 and a cammed specV with other mods. Running the 50shot for the first time since Im up against some stiff competition. Hope the clutch can handle it. Later Everyone.
The experimiment shall be continued at a later date.

good luck with the races.....

if you want to run dry ice, use antifreeze mix instead of water.

Chemically, pure water cannot go below 32 degrees F. So that means that you will never get the TB any colder than that.

But then again, a very cold TB brings up another issue itself.... freezing.

That is awesome...way to think out of the box bro!! Good luck with the races and have fun!!

turboengnr is correct. About the freezing, maybe this would only be useful for summer because there is still hot air coming from under the engine through the TB. In the winter, problems could occur.

If you really want cold liquid, mix the dry ice with ethyl alcohol and screw the water. That will get alot closer to the temp of liquid nitrogen :) :) But again, I'm not sure how that would affect the pump. If there is anything but water, it may mess with it. But I don't know how it works only about what the manual says.

hey man, i had an idea,..kinda,...I was reading a book bout Civics, and it said something about how "back in the day" people used to use "dry ice boxes" to get cooler air flowing through their intake,...you could try something with dry ice maybe? I believe the by-product of dry ice is Co2,..just so ya know....... ok..just read other msgs,..you already got that...
~mike~

OMG!!!! :giggle:

cut a hole in the hood above the TB...........get another external pump (inline), water tank, lines, a oil cooler and chill the water that way....it can be run from a switch.

the stock winshield washer pump can handle running alcohol through it. So you can run the alcohol idea as well. And since it doesnt move a lot of volume, it wont cool it down as much as if you were to use a bigger pump. This may be enough to cure any freezing problem you may run into (during the hot season)

CO2. dry ice is the same thing. you can get it in liquid form though. i don't know how expensive but for your experiments it might be worth it. good luck with it. you can also try freon gases and other gases/liquids that would help the lines stay cool. try gases. you might be limiting yourself if you stick with liquids. good luck and tell how it goes.

OMG my NA 1/4 mile time still owns your 50 shot 1/4 time.
:giggle:
I was bored and in the name of science I conducted an experiment. :rofl:

it would be cool if you could find a way to circulate co2 or No2, that may also work in some way shape or form

Heres another thought. If you are chilling the air after the IAT sensor your computer isnt aware that the air is colder. Try epoxying it in the manifold after the TB. Keep trying, its a good idea.

Your civic may be faster but mine looks MUCH better. :)
When i want power i hop in this, not my civic. :giggle:

I assure you this will own your civic with or without nitrous. :lol:

Isn't there already an intake like this on the market I think its called the Cry-O2 intake or something like that, where instead of circulating fluid around the TB itself it just freezes the CAI piping w. dry ice?

but its VERY expensive. They also have a dry ice intake which is basically a normal intake with extra tube to put dry ice in. Only thing I worry about with that is water vapor condensing inside the intake tube and getting sucked into engine.

Getting off topic so maybe we should take this some where else. Here we go

what about hooking up an actuator that turns on the windshield wiper pump when you floor it, like the achohal inj. in the sf turbo kit?
