I was looking at this circut chiller the other day that is supposed to bring down the tepmerature of what ever you spray it on to -96 F! Man if you sprayed that on your airfilter housing you could have maybe a 20 degree intake charge! It would probably work even better on a mandrel bent metal custom setup cause there would be a lot of surface area for the air to be on contact with and it would be in the tube longer before it reached the carburator or throttle body. It may have a chance a of cracking the airbox but there are a million of 'em in junkyards. What do you guys think? I'm gonna try it this weekend and see if it makes a difference.

 

I think it would work great for 30 seconds until your carb ices up and the engine stalls

 

really? I thought your carb needed a cool intake charge. I don't think it would be THAT cold would it? I thought carbs only iced when it was humid AND cold outside. Now that I think about it the air filter housing would be frozen but the air would move across it so quickly it probably would only drop the temp of the air by a few degrees. Oh well I guess trying couldn't hurt. I'll let you guys know how it turns out. Hopefully no carb icing.

 

Well, think of this... hot air can hold more moisture than cold air. When you cool off hot air, a lot of water condenses... this is why A/C systems drip and is the basic reason why fog forms.

Give it a shot, but expect it to ice up fairly quickly Incidentally A/C systems are designed to never cool below 32 degrees for this very reason... if it cooled below 32 degrees then the evaporator core could ice over and no air could flow through it.

 

Also rember that air that is cooler is more dense with oxygen and will require more fuel to run properly. DO let your engine get too lean.

 

That's the beauty of carburetors - for the most part they self-compensate for temperature and density.

Don't worry about running too lean on a N/A... it won't hurt anything, just make less power, maybe misfire.

 

Carbs self compensate? how so? I figured i would need to go with bigger jets or tweak up the fuel pressure when i put on the cold air intake I'm making. (not the circuit chiller -96 degree thing, just a plain old CAI.) And I know i feel a very noticable increase in performance when I travel back home, about 2000ft lower in altitude. I know that the air density will affect the power i make just 'cause there is less oxygen to burn, but i also thought that the carb would not deliver any different of a fuel curve to compensate. So if i jet it for home, when i go up 2000 ft for college, it will run rich. Hmmm. maybe since there are more air molecules packed closer together at lower altitude as the molecules rush though the carb they pull out more fuel than if it were thinnner air. Is that what you meant by self compensating for density peejay?

 

If you want a cold intake temperature just come drive around up here in Alberta Canada where it has been around 0F as a daytime high for all of march. With my cold air box my car feels faster but the roads are so slippery I can't floor it.

 

The carb will have to be adjusted for the cooler air. I rember those vacations from Texas to the Colorado Rockies where dad had to pull over the camper and have the carb adjusted for the cooler air and less oxygen in the air.
