OK. cold air intake, and innercooler. both are designed to make sure your engine gets colder air, right? Well, i was driving around in my car the other day with the A/C runnin wide open and i had a bit of a thought. What sort of benefit would you get if you took your A/C unit, and instead of piping the Cold air into the cab of the vehicle, you were to reroute it to be piped directly into your cold air intake? Would this idea be worth the trouble or would the cold air being taken in through the intake just be negated by a turbo charger unit heating the air back up agian? If i'm hitting on a previous idea just let me know, but i was wondering about this.

 

running the AC would take more power than that would ever give you.

 

its an interesting idea, as the ac would cool the air bloody cold if you found a really small evaparator (i think thats the part in the car) like from a tercel. then build a air box around it, and plumb it to the intake system. but like entropy said, it prolly would take more power than it would produce, unless you were to really turn up the boost, and get bigger injectors. the only way to find out would be with a dyno, dyno the car with a good stock tune, and start there, then start the modification!

 

your AC blows like a couple hundred CFM, what's your car burn a Minute?
Anyway, you put really cold air through a throttle body/intake and you get ice. Ice although cold isn't so good for flow.

 

i'm sure with a little thought i could find a way around the power loss from running the AC. But moneys tight right now and i can't do the experiment myself. Maybe later. it was just a thought i wanted to run by some more experienced folks.

 

not to be a buzzkill, but you will not be able to get the AC to push enough CFM to do anything.

 

Oh well. it was just an idea entropy. maybe some rich turd with too much time and too little to do will read it sometime and put his/her massive money collection to good use on the idea. creature comfort technology is prolly not suited to performance use anyway.

 

wasnt their a guy who took a water cooled IC and ran the water lines from the IC to an ice chest filled with ice water and a small elec. water pump in the trunk?

 

Sheesh... too much effort. Why not just throw on a NOS spray bar infront of the IC. Sometimes people think TOO hard.

 

because that only cools it when your spraying on it, this would efectivly keep temps down and would you wouldnt have to keep replacing the fluid, just ice..

 

dont even have to waste spensive NO2 you can just use good ole fashion CO2 for the spray bar. would do the exact same job what you just described sorta wroking like an A/C condensor but faster and more efficiently and less time/money/research productive. btw.... im back from ohio beeches!!!!

and hoov, your idea only works for a few minutes until the ice melts. drag cars use that alot. charge temps are pretty high most IC's bring down temps aout 100 degrees so that ice will melt some what quickly. will probably last a little longer than a sprayer bar though.

 

i would kinda be lookin for a Long-Distance type of cooling rig. 1000 + mile races and the like. an Ice chest and a water pump wouldn't really work. i'd be stoppin at every circle k between Baton Rouge, LA and OKC with that set up. And i'd have to carry alot of extra no2 or co2 for the sprayer bar.

 

J... spending lots of money & time to lower the intake a few degrees just isn't worth it... you could focus on quite a few other things to make the car run better / quicker for less. If you're so worried about intake temp, bypass the TB coolant passages & rewire the injector fan to blow all the time to remove engine bay heat.

 

yeah. i wasn't about to go nuts with it. i don't have the money, and i definately don't have the facilities for it. I was just kinda seein what was out there. Something to do between parts shipments and payday.

 

It's kind of like the old hotrodding trick when they used to put a bag of ice around the fuel line to gain that extra fraction of a second in a 1/4 mile time.

 

This idea would work well if you can get around the drag the AC compressor puts on the engine. You wouldn't be using the blower motor from the AC system. The best way to execute something like this would be to place the evaporator coil in the intake box after the filter and seal it all in. The engine would draw the needed air through the evap coil. If you're concerned about the drag of the coil another option would be to wrap the inside of a section of the intake tubing with copper tube for the freon to flow through. This wrap of tubing would be open enough in the middle to allow air to flow smooth, but still cool it using the copper tube as the evaporator. There's plenty of ways to make this work, but only if you can overcome the drag the compressor has on the engine.

 

hes not talking aboot making the ac blow into the air system, but just putting the part under your dash (the part that cools) inline the air intake system, so the air has to flow thru it. it would effectivly make the air really cold b4 it goes into the system, more so than an intercooler.

 

untill it hits the turbo and heats right back up.

 

yeah, i kinda axed about that turbo heating thing before.

 

Doo it... Doo it...

 

Alright, alright! I get it nismo, it was a horribly impractical idea. Its runnin fine right now.(yeah, i'm stoked.) So i'm not making ANY mods to it until maybe after Labor day weekend. i'm just gonna check it over and make sure its ready for the road.

 

my cooler fan runs all the time, intake temp seems to be lower too, plus i cut out all the webbing, and still run the heat sheild. i think it helps, but it hasnt been dyno proved. and heck, put the ac unit after the turbo, kinda gets rid of the turbo heat then, but it may freeze everything up, id actually like to try this, as even my n/a loves cold air, read my sig, its how i found out! hahaha

 

if you do it, then lemme know how it works shady.

 

now you guys got me going, im pulling my spare ac compressor outta the garbage, ill giver a try on the bob sharp racecar. i can modify it all i want and not worry aboot it going to work in the morning. it may take a year, but the hamster in me head is on overdrive now. i got 5 nissan vehicle projects on the go. my silver car, the race car, the 620 truck, the 2000 xterra, and my newest possible truck, an 85 king cab 4x4, with the 8 spark plug head.

 

gimme gimme gimme gimme!!!!
