intercooler

Just a though............probly stupid, but what would an intercooler do for a N/A? In technical terms, getting cold air in the intake/throttlebody. Would it work? dont care much about HP gains, its a N/A.

It would do nothing. An intercooler is there because turbos make air really hot.

yea but could I use it to get cold air into my engine. Does an intercooler need a turbo to run?

no it doesnt need a turbo to work an intercooler is just a heat exchanger radiating the heat and passing air(via fan or grill) through the channels cooling off the air flowing through it...

no u wouldnt see a gain because the temps in the engine bay,intake and piping and the intercooler would probly be close to the same engine bay temperature. the intensified heat created by compressing air is carried along with the boosted intake charge the intercooler isnt nessarily cold but its temperature is less than that of the intake charge thus cooling that air to a certain point and assisting in making more power because colder intake charge means denser air = more air going in witch means more fuel witch means more power.....i hope that helps clear that theory up!

umm yeah.... how could you possibly cool the air in the intercooler any lower than the ambient temp?

Intercooler on a non turbo would be more of a hinderance than a help.

See in the simplest terms; intercoolers work by cooling the air that has been heated by being compressed.

Since the air going into a non turbo is never compressed (until in the combustion chamber) there is nothing to cool.

i can not see how you wouldn't get a gain in power? because the intercooler cools the air befor it enters the intake the ida is that the cooler the air the more air that can be packed in wich means more power. it is uncomin but i belive there would be a power gain.

intercoolers have nothing to do with the heat product by the turbo and i've seen cars that are turbo that are none intercooled

Think about it, you are trying to cool air inside the intercooler with air outside that is the same temperature as it would be with a normal intake. Just because air is blowing across it doenst mean it is cooling. Also, all that tubing would heat soak and raise the air temp alittle.

what is it going to cool???

It can't cool the air that is the same temp as the cooling air. IT cant make anything more dense than ambiant pressure.

You need to take some basic mechanics classes, because either you just don't understand this at all or you are just making a joke, if you think there would be any gains.

And not all Turbo cars have intercoolers, just ones that run more than 4 or 5 psi

Wow....no comment.

In any case,listen to Icemark.
An IC on an N/A car is pointless and if anything will decrease performance, because its just DEAD WEIGHT.....

just a thought. what if you had an intercooler and sprayed it with nitrous or iced it?

you might get a little more power, but I don't know if it would be enough to make up for the restriction.

And of course the gain would not be anymore than when starting and driving on a very cold morning.

Remember a typical intercooler has about a 1 psi drop when pressureized to 10 psi, and a few of the better intercoolers have a .2 psi drop.

When you are already running only at ambiant, any loss because of a restriction is pretty tough to make up.

Hey maybe at speed the wind chill effect will help drop temps a half a degree or so. =P

May as well just hook up a nitrous kit. Probably be easier and get more power gains.

yo i think the origional poster was probably wondering 2 things
1 the cooling power of an ic
2 how to significantly chill the air in the intake

weve established that an intercooler wont ool the air any ooler than the engine bay air with which it is exchanging the heat.

that said, I realize a turbo condenses air and an interooler doesnt, but somewhere else it is poste 38 deg. farenheright = 1psi
or 3 deg. = about 1 hp

so everyone knows the best way to get cool air to an na is to install a cone filter, cold air box, with a fresh air filter, but beond that, anyone have any good ideas of how to chill/cool the air significantly

and BTW new to rotaries, but isnt hooking nos up to any car super stressful unless you replaces seals or something (even tho it is a rotary....) i know you can do it but wont it significantly decrease engne life with frequent nitrous use?

No more than any other type of forced induction,and yes nitrous is forced induction,its more chemical than mechanical,but its primary purpose is to increase the oxygen content of the intake charge.The fact that its a liquid that vaporizes in the intake means that it has an internal intercooling effect,which is an added plus.

The reason people get into trouble with nitrous is because they either hit it too low in the RPMS and bog the engine,or they run a cheap, easy dry setup that doesnt add more fuel to match the increased oxygen content.If you use nitrous properly and keep the fuel delivery in balance,its not more detrimental than a turbo or supercharger....in fact its probably better.With the aforementioned intercooling effects and the lack of complexity,plumbing and weight,its a superior form of supercharging.The main downside is legality,and the fact that its an expendable power booster.

Get rid of the intercooler and rig up an air condenser and pump air conditioning into your engine... mmmm.....

that 550hp ford truck thing i saw in a magazine would use the AC to store cold air, and would take about a minute to cool and store it, then it released it into the engine in one big charge and was only good for a short period but was worth 50 horses on it, alot less power on ours but would still work if we had a way to kick it on and off and store it and such.....too much of a complication and mess really......

i have an N/A so theres no intercoler to get rid of,
if you could get a good electric ac you ight be able to get 30 or 40 degrees,
or some other way to cool it, with a fan presurizing your air at low speeds or some wierd electric air comressor setup, could be quite a few extra horses from the stock air box.

I know a turbo is better, i know thheres no magical goo to super chill my air as it passes through the filter, just lookin fot ideas.

and does anyone know how long 2 100 shot bottles on a wet spray at like 3800 would last about?
