I got the thermometers installed , getting ready to take a ride , just waiting on the outside temp to come up a few degess so i have the same conditions ....

 

it was about a year ago on another f150 site that i asked about the cold air intakes. long story short what most people think of a CAI is really an open ellement intake in which it just draws in warm air from around the motor. also all of our trucks are col air intake via the factory. they gave me a link to a website that had beeen testing different theories. if i can findd the link ill post it. they basically had 4 different tests. they had the regular sotck truck, the so called CAI with a k and n filter, a k and n drop in filter, and a k and n drop in filter with the intake tubing wrapped in the heat repellent tape or w/e it is. the one that got the worst mpg was the open element. if i remember correctly the one that got the best was the k and n drop in with the tubign wrapped in that special insulating tape or w/e that reduced the heat from the engine bay from warming the air.

if i was going to do a CAI i would either go with a ram air hood bc they look sweet OR a k and n drop in with the i6/460 lower tube wrapped in the heat wrap.

just my $0.02, which i have come to loearn doesnt get you very far these days.

 

Ok results are in , there just about the same , the 95 with the cone filter was 104 degress about 4 degress cooler that the stock system , so i learned that the exposed cone filter dosn't suck anymore hot air than the factory airbox , also under the hood ventalation is important to keep the temp under the hood cooler , now i need to do this on a real cold air intake.....Oh and the temp reading at the front of the grill was 96....Lew

 

I would think hood scoops that face towards the windshield would enhance air flow in through the radiator & from below the engine, across the engine engine & out of the compartment. Especially because heat rises. It's important that trapped hot air can escape in order for it to be displaced w/ cooler air. Sure would defrost your windshield quick in the winter!

 

Yeah i have the cervinis front air dam with the vents in it & a cowl hood....

 

Still, what's the effect of the coolant through the air intake body? Does it also reduce the temp in relationship to the radiant heat created/transferred by the EGR Valve mount proximity. That puppy gets "HOT"!

 

Yeah i took the temp from the air intake tube before the TB , i disconected the TB lines and eliminated the egr on my truck...

 

Thank you sir very good information.

I owe you some more rep points when I can.

 

Your welcome !!!!!!

 

I always wondered what, if any, the performance gain would be if you routed the intake to pull air from the cab since my A/C blows out at about 60 degrees.

 

I never thought of that....it is a good source for cold air but with the windows being up i think it would suck everthing out of the cab , fast....

 

Wish i woulda seen this thread sooner. We have been all through this about a million times on the PSDs. You will find that when your stuck in traffic you will have slightly cooler intake air temps from a "cold air intake", but when your moving at anything over like 20 mph the amount of air that is traveling into the engine compartment is so great that the temps over by the filter aren't effected much if any. We have seen very very minimal difference between using a "cold air intake" and an open element. Like less than a degree difference. This is why you see most of us running open elements. Since there is almost no difference in the intake temps between the two, it is better to have the open element(as large of a filter element as possible) to pull air from as large of an area as you can. I did an open element on my F-150 for this same reason. under hood temps will not differ that much from ambient when your moving 40, 50, 60mph down the road so there isn't a reason to pay the extra coin for a "cold air" intake... Good job on the test results Lew. i'm sure you would see the same thing if you did a "cold air"

On Edit: my buddy runs the air filter in the cab of his mud racing truck to prevent getting the filter all nasty. It does not have A/C, but it works pretty well. His mud truck has a blown 460 and you can hear the blower real nice inside the cab! :-)

 

Thanks Travis !!!!! thats what i have been looking for

 

No problem man. I used to think the CAI would be better, but really under the hood of our trucks it doesn't make a difference. it might in some cars, but not on these. i can try to find the threads if y'all want. there was a few of them. This is the only reason i went with an open element on my 302 and my diesel.

 

Yeah thats what i run in mine , a pro m air meter with there open element filter , so im good to go ....
