Not saying that it happens every time, but it is a possibility under the right conditions.

The CAI set up looks effective though :thumbs:
LOL at people believing that water has to sit in the radiator to cool off.

The water does have to be in the radiator for more than 10 seconds to cool off though....the coolant will not cool off by flowing through the raditor in a rapid rate under certain conditions.

That's where the largest heat transfer in the cooling system occurs

Not to mention that I've known a few guys in the past who have removed their t-stats, thinking it would be a performance gain, just to have their cars/trucks overheat....coincidence?

It sounds like removing the thermostat is analogous to endotoxic shock causing a high output heart failure. lol.

Bud, this is the first time I've seen you confrontational in a post! Congrats! Make sure those eyeballs don't roll back into your head

Come on man, 10 seconds? So does the air going through the radiator have to pass by it slow so it can pull the heat out of it? LOL.

I'm sure you knowing a few guys trumps me personally doing this to some of the cars I've worked on (including my own) and them all running cooler. Is this a great idea for all cars? Nope. But it's worked in the cars i've done it to that had cooling problems.

Air is a gas and has different physical properties than engine coolant...my best guess. I just know from 1 guy with a mid 80's Caprice (305 sbc), 1 66 Mustang, straight six, and a few other sbc's that I've seen, removing the t-stat=radiator overflow boiling over, steam under hood, and temp gauge pinned.

I did it to my own 71 Camaro when I had overheating problems...it got me through until I fixed the actual problem. Like you said, it's different for different vehicles with different cooling systems...if it works for you, go with it

100%, correct might not effect everyone in every weather condition...

Yeah i like to try stuff out for myself. I find you learn a lot more that way.
