3rd volume of hillbilly rigging theory

[frosti108]

ok so 1st, we considered the radiator as an intercooler.

next i bought you the oil dipstick hole as an oil return route.

NOW (drumroll) i present. air conditioner intercooling :eek:

on these hot summer days, dont you just wish u could cool that intercooler off some how??? what if you rigged up the air conditioning ducts right onto the intercooler? i think the cold air produced could possibly outweigh the parasitic draw of the a/c compressor. it would be cool to see.

but see for my setup for example, my a/c doesnt even fit on at the same time as my turbo. (for that matter, half of the motor mount didnt fit either :P )

so yea bring on the :squint: and the :loco: and maybe some :keke:

what do u guys think of this idea. keep in mind its been close to 100*F around here lately

Interesting but this won't work though...

Even if you ran every vent towards the front of the intercooler, the air would not be able to compete with the outdoor air... It would literally do nothing except keep the AC compressor running...

Stick your hand out the window at 50MPH and compare it to your AC at high mode... It won't stand a chance...

[holybushoffire]

just buy a radiator mister and point it at your intercooler, or you could always just buy an intercooler sprayer kit... hmmmmm..:rolleyes:

[codyace]

I thought you were selling your car?

Get a proper intercooler, and be done.

[nissanguy13]

I was thinking the same thing as already said above. Spray kit.

[!Zar!]

Omg. I love this.

[frosti108]

lol why would i ever sell my car.

and yes i found my intercooler im gettin it this weekend! :D

[frosti108]

i gotta go to work but real quick...

this could possibly help like sittin at the tree at the dragstrip or at the red light...

same concept as the sprayer except you already have it installed in your car from factory, you would just need to redirect it.

and about air flow... maybe instead of dropping the cold air right into the wind, you could route it through the inside of the intercooler sort of like a 2nd smaller intercooler interwoven into the engine intercooler


lol aiight off to work

I agreed with the mister posts.

The mister would help you a lot more than your theory of the a/c vents to the intercooler.

There's also a CryO2 intercooler sprayer info below.

In theoretical terms, if you got a "water cooled" intercooler, and instead of running water inside of it, you ran a freon duct through it, you could cool your intake charge by quite a bit, but that is a hassle in itself.

[bigOdom1]

i think the ice cooler ac is a better optionlink here (http://www.roshgo.com/Merchant2/merchant.mvc?page=rc01/CTGY/00408)

[daryl337]

yeah, well im talking theoretically, it would work similarly to an intercooler spray system, only it would run off of your AC system... practical? No. Haha.

:werd: That was the type of spray kit I was talking about. I think you should just take your i/c off and stick it in the freezer over night and put it back on right before you drive the car and/or race it. It wouldn't cost you a dime.

or instead of spending money on an intercooler sprayer, you could just re-route your wiper sprayer to spray on the front of your intercooler/radiator. all wired up and ready to go.

haha cool idea. i thought about this before, but you would would have to add ice to the window washer ress if you really wanted any real help. otherwise the water is the same temp as your engine bay

i like the idea of running the freon through the intercooler daryl. why wouldnt it be practical??

[lazierhobo]

washer fluid chills off in the corner, it doesnt get that hot. and it isnt about the temp of the water, its about the intercooler being wet, water...evaporative cooling....conducting heat away. that kind of shit.

throw warm water on your face then stick your head out the window while your driving.

[misfitsfreak81]

what a waste of server space...

Because you don't drive a 500 whp race car.

If no one else has ever had trouble doing it traditionally, why try to re invent the wheel?

Its easier to re-route the intercooler piping to the passenger side and vent the intercooler there.
You just need 2 holes in the firewall and thats it!!

And it will cool you also!

[daryl337]

Well, if you are trying to run it all off of an AC compressor, there are limitless amounts of possibilities for you to have problems in the end. Routing the high pressure hoses to the cooling ducts of the intercooler, making sure everything seals without any condensation is a must otherwise you will burn your compressor up. So there will be alot of effort being put into this system to get it to work properly. Of course once it does, it will be really handy to have since you can simply turn your AC on and it will lower your intercooler temps as long as you need it to (instead of periodically spraying onto it). A system that is properly set up would have a ton of additions, but as Codyace stated, unless you are in severe need of these benefits, converting over to this sort of set up would be un-necessary. Plus, adding the extra freon each time is gonna be spendy! XD

[frosti108]

eh it was just an idea. i dont see how its a waste of server space.... this is an internet forum... its where a lot of crazy shit gets thought up. its not bad to stray your thinking from the usual once in a while. its not reinventing the wheel, its just trying to help it out with some smoother bearings lol

[MELLO*SOS]

Just wondering if you've ever studied physics? These ideas you have aren't original or creative they are plain n00bish stupidity, easily discredited with a basic understanding of physics.

But I'm bored... So lets look at this idea of the AC chilled intercooler.

First off, do you have any idea how much horsepower it takes to drive the AC compressor and blower fan? I did a quick search and found a guy with a 3.0L z4 bmw did a dyno test on this. He found out that it cost 11hp on his 232hp engine, a 5% loss.

http://imgup-lb.automotive.com:8080/files/1038554.w700.jpg (http://blogs.automobilemag.com/1007156/tech-talk/your-cars-hidden-turbo-boost-button/index.html)

So with that information lets assume on a stockish SR20 with 200whp you can expect a [5%] 10hp power drop at the wheels when running the AC. So now your AC-FMIC chiller will need to add at very least 10whp just to offset it's own parasitic losses.

The rule of thumb is that for each 10 degree drop in charge temp, you pick up an (approximate) +1% hp increase. On that same 200whp motor, you will need to chill your intake charge by 50 degrees in order to break even with the AC compressor losses. Already that's asking quite a bit, considering you can't get the cockpit much cooler than 70* on a 100* day. To even be considered a worthwhile upgrade, lets say by adding 10hp to the wheels, you would need to achieve a 100 degree drop in charge temperature! NOT GONNA HAPPEN!

Your idea is just a glorified perpetual motion machine. It's basically the same idea as using an electric motor to drive a generator, which is then hooked back up to the electric motor.... In the end the mechanical energy losses make it unsuitable. This is why you don't see any track cars, or street cars for that matter, running an AC-FMIC chiller. Instead they use a bottle of CO2, or a water spray tank since those do not sacrifice engine power to chill the intake charge.

Looking forward to round 4 of n00bishness. On second thought, why not go work on your car and only post tech questions?! Or at least post new ideas that don't blatantly ignore the laws of nature...
