idiocy, or genius?
theres a kid in my business managementclass in HS who also drives a ranger (not an rf member) and he said today that he put a pipe from his AC vents behind the dash, into the engine compartment somehow, and into his airbox, and wrapped it with heat sheilding.
(i'd love to see under the hood to get a pic for "what not to do/with a ranger")
how much of a bad idea is tis? give me some ammunition for class tomorrow. or argue for him, if you think that it might be worth it.
i know i laughed REALLY hard when he started telling me about it, and i figured you guys might get a kick out of it too.
only in Culpeper VA...

Doesn't sound like a good idea. I'm guessing he wants colder air going into the intake.
The problem is the intake already has outside air being pulled into the truck. So that air would also go down the duct work he has laid out. The A/C would have to work harder to push all that air through the intake. Now he could have it routed so the outside air doesn't go down his ducts, but w/e.
Plus wouldn't he lose some cold air that he could be using to keep him cool?
It just sounds like a dumb idea

tell him to buy a tornado and throw it in there.
i'm not an engineer but i do think that his a/c would have to work harder since it's technically a "bigger area". our a/c's are only designed to cool an area as big as our cabin.
kinda like one at home. you wouldn't use an 8000 btu one for a factory.

Remind him he has a ranger, not a dragster. Lets say it does work (but probably not) and he picks up an extra 5hp and a 5% increase in fuel economy. The second he flips on the AC he's losing the hp and efficiency from the ac being on. Lets say its hot enough where he would be running the AC anyways, well... I know i'd rather have all the AC going into the truck to keep me cool.

it takes power to make power though... look at a supercharger... it's got a paracidic drain on the motor to turn the screw... i don't think that the drain on the motor, for the A/C would be enough to make a big difference... but CAI kits don't make as much of a difference as people think they do... it's mostly in the airfilter, and the smoother intake pipes, less restriction...
i think it's a dumb idea... would have less of an effect than putting bags of ice on your intake before racing it (people used to do that with mustangs back home)
but as posted above, we don't know his side of it

Tell him to make a box, put 5 lbs of dry ice in it. Then pull the air over the dry ice in the box. Will work WAAAY better, and you just toss in some dry ice when its drag strip time.

Looks like your the first person in this thread to realize the engine has to turn the a/c pump. Thus making it work. Why the heck you driving around all the time with the a/c make you go faster? I did a run at the strip in a friends car with the a/c on on accident and it was almost 2 seconds slower....

i told him to join a while ago but he says he doesnt have a computer at home. and i did point out to him that the AC being on does add considerable strain on the engine but he's not getting it, i'm gonna give up on him. feel bad for his poor truck though
and morris, do those tornado's really do anything? i've head of them but not alot

Doesn't have a computer at home? I thought all kids in school were required to have a computer these days. Anyway, it sounds like the kid knows his Idea will be shot down and doesn't want to visually see what others have to say.
Besides, if his idea is so great (as he claims) it would have been done decades/years ago.

Do you really have more noticeable power when it's like 15 degrees outside versus say, 75 degrees?
Do you think that your blower motor output routed through 6 feet of homemade ducts can keep up with an engine's thirst at anything over idle (hint...go feel the exhaust pipe output at just idle)?

I say let the guy have his fun. It shouldn't hurt anything and he can find out for himself if it works or not. Many innovative ideas come from people that like to experiment.
As I recall, at least one version of the Lightnin use cooling from the A/C to the inter-cooler for the supercharger to help boost power. I know cooling an inter-cooler will have a greater effect on power than cooling the intake air on a normally aspirated engine but every little bit helps.
I don't think he is going to gain anything by it either but I have seen hot days in Las Vegas that I would like to have had a little cooler air coming in the intake because my car had detuned itself so much from the heat it could barely pull itself away from a stop light. On the other hand, I would not want to give up the cabin air comfort either.
