is this possible?
 

ok i heard about and saw a kit that sprays your radiator with a nitrous or co2 to increase the cooling affect the radiator has and so you get a boost of cooler denser air. it says its typically used for turbo or supercharged cars where regular nitrous is not possible. would this actually work? and can something be set up on a NA car to spray the radiator with nitrous/co2 or water to cool it to force more cold air into the intake? now this is not the same thing as the thread a while ago talking about sprayin co2 into the intake we know that wont work, but what about spraying the radiator to cool it?

Re: is this possible?
 

The kit you're referring to is designed to spray cold CO2 onto an intercooler , not a radiator. Cooling down a forced induction air charge is a way to pickup a ton of power.

Spraying down the radiator will cool down the coolant temp briefly...so it might be a neat thing to do at the track while you're waiting in the staging lanes! ;) But you can pretty much do the same thing with a bag of ice, so I'd spend my money elsewhere if you're still running N/A.

yeah i know about the intercooler set up but this said it was for a radiator. could a intercooler like setup be used on n/a cars? to get cooler air into the intake?

Re: is this possible?
 

Intercoolers work great on FI cars because the air coming out of the turbo/supercharger is VERY hot. Compressing air produces heat (see Boyle's Gas Law). IATs are often well over 200 degrees without intercooling. So a 100 degree drop is worth upwards of 50+ horsepower (often more), not to mention reduced chance of detonation. That is why every serious FI car has some form of intercooling.

You would not see any benefit to "intercooling" an N/A motor, since the charge is not heated up prior to entering the engine (the air is not being compressed prior to entering the motor). One way to substantially cool down the intake air of an N/A car is to run nitrous... ;)

thats just stupid. i know the intercooler works but a radiator? let the import guys have that one lol

Re: is this possible?
 

its not stupid if it gets a win.

If you buy that for your RADIATOR, you are dumb and just wasted money.

As I posted earlier in this thread, there are plenty of ways spend your hard earned mod money that will pay WAY more dividend.

Do not even try it, even for a FI car. Co2 is bad and will get sucked into you engine. co2 is your engines enemy and will rob you of more hp then you will be able to gain with your cooling setup. cooling your radiator will do next to nothing. I know if my car runs even 10 degrees below 160 it will miss in the higher rpms.

If 40 degrees were the ideal temperature cars would not have the cooling systems them do. Combustion mixtures ideal temperature is something like 200 degree farenheit i believe. Any colder than that and you can get spark blow out. Running coolder just allows for more dense air/fuel mixtures. The colder you engine is the worse you emmissions will be.

Anyway a manual fan switch, TB bypass, and a 160 degree thermostat is the best cooling setup IMO. Also you could get an oil cooler. Oil has alot to do with cooling down your engine as well.

Re: is this possible?
 

are you talking about running an intercooler without a blower or turbo? or acutally sprayin no2 on your existing radiator?

Re: is this possible?
 

Yeah, intercoolers won't give you any gains N/A. Even turbo cars question the gains. Upgrade you intercooler and provide dyno numbers for intercoolers. I have yet to see any.

Please find the link where you saw the kit.

Spraying the radiator probably wouldn't help at all. If the rad isn't to the thermostat's opening temp., it wouldn't cool the engine at all. If it was over that point, the engine is probably heat soaked anyway.

I can't imagine why anyone would spray nitrous through a radiator on a n/a car(or any type of car). Put it in the intake where it belongs.

Re: is this possible?
 

Those setups spray CO2 ACROSS the intercooler, not into it!!! :no:


Are you serious? Upgrading an intercooler to one that has a greater efficiency can have a profound effect on air density that enters the intake. A better intercooler allows more boost to be run, and will make more power at the same boost level as well.

Actually, engine builders in the know such as Lingenfelter will tell you to run oil temps at LEAST 210 degrees, with optimum being 220. Meanwhile coolant temps should be in the 170 range for good horsepower production. Cooling down the oil below 210 will do no good for your engine, and will have little or no bearing on "cooling down your engine".

Please do some research before making posts that someone might mistake for actual good advice... :rolleyes:

Re: is this possible?
 

The c02 will stil be sucked into the intake by the filter somewhere if you spray it onto the intercoler. Even at idle you can feel the how much air is sucked in by your engine. If you want a kit that runs down the intercooler intself here is thread about it.

Find me dyno numbers. I have yet to see. Scroll down and read post #5 Then scroll down the the bottom after the guy installs bigger intercoolers, goes to teh track and actually runs SLOWER

Our egines oil runs about 300 degres correct? So cooling it off would help our engines then. They make kits with temp sensors oil radiators and fans to keep oil temps around 200 degrees.

None of that was advice, just my opinion and what i know... I remember mindgame saying "If everyone agreed with me i wouldn't learn anything." In any case a Co2 sprayer kit like the one i posted which runs though a tube around the intercooler custom made for a radiator will do nothing for horsepower. A manual fan switch would be much wiser. If you want to run that absolutely cold you could just take out your thermostat but it's very bad for oil and engine wear.

Shawn, you can't take one guys experience with intercoolers and run with it. True, you can install too big of an intercooler, but if your motor is in need of an intercooler with more cooling, it will benefit obviously. If you can make the air cooler without losing boost due to pressure drop, an bigger/better positioned intercooler is the way to go.
