Intake: Open Vs CAI

Not true.

Even at hig way speeds when i ran open cone was always 15-20* over ambient. always.

back when i was modding i tested this on my 01 top swapped XP GT. i saw zero diffrence at speed with box and with out. only time i saw any thing was at idle in traffic with out box temp would go 20*-30* above ambiant but as soon as i would hit 25mph it would go back down to 3* below ambiant

at speeds of 30mph-50mph it was 3*-7* below ambiant depending on humidity levels at highway 55mph-90mph it was 10*-15* below ambiant for both

here is what i had on the 01 non-boxed 4" id PVC and 4" id cone filter. it was larger then the throttle body

this same intake is currently on a L67 swapped 97 GT
 


lol no such thing as 4"od pvc :P unless its 3.5 id, then i think it ends up as 4"od. i fell in love when i did my first intake setup, i thought it was the coolest **** cuz it was the first mod i ever did and it was sweet as hell to hear the new roar from it over the stock intake.
 
yeah i found out about 4"od not existing lol i made that back in 07 when i first started modding w-bodies

and yeah it screamed.

seriously why put a cai on a car that will make heat after it goes thru the supercharger
and it's not like the cai for our cars are real cai
the k&n doesn't even seal it off from the rest of the engine bay like they do on other cars and trucks

and having done all 3
fwi, cai and open cone, i'll stick w/ the open cone. it looks cleaner in the bay and it doesnt effect iat because when you move anyways our gonna get right at ambient

first the op is n/a not supercharged, so isnt go threw a charger getting hotter.
And im ALL city traffic, and considering post #41 he saw over 30* ambient sitting at lights with open cone... Id rather have cold air intake, i got my filter inside my bumper so i never get engine bay heat.
 


i don't have a response anymore
i'm going to do what i want anyways
i live in florida and ambient will always be over 100 in summer, so no matter what i will get hot air in the summer
 
been a bad monday for reading..lols.
but even post #24, 15-20* over ambient highway cruise....if cooler air wasnt better why do turbos and chargers get intercoolers. i know its WAY cooler air but still, cold air is better air.

Can't really compare the two because that is cooling the air after it has been charged but yes colder air is better colder=more dense=better.

MAIN POINT-

A CAI is better. Are you going to see a huge gain, no. Colder air is always going to be better though going in even if it is only a 20* or 1* difference. For what you pay to do a CAI out of PCV it's almost a no brainier.

You know what is more of a no brainer?

The fact all of that is moot because your intake runs RIGHT OVER THE EXHAUST CROSSOVER AND GETS STUPID HOT ANYWAYS REGARDLESS OF INTAKE SETUPS.

Who cares...you want to avoid hot air? Do a FBody intake swap and turbo your car. There, passenger side. Nothing hot there.

I win.

Intercooler lowers temps more than any intake can. This thread does not deliver.

Post blower temps sure...but not the initial intake charge...

See my post for failure of GM.

Exhaust crossover killing us.

And no, wrapping and ZZP's little tin foil coke can heat shield ain't stoppin' it.
