Thread: Intake: Open Vs CAI

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

larger is better. the more air available, the better the flow

it was more of a good accident when i did that i though it was 4"od not 4"id lol

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.

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.

that chart is hilarious.

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.

how so

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

because it's insane amounts of generic and has no basis for any vehicle in specific. i GUARANTEE that you will not gain or lose that much power with a 100* temperature swing.

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.

and this thread is meant for an n/a car, so whatever.

When considering how to design an optimal induction system for a particular vehicle, all of the design aspects discussed earlier as well as other characteristics must be given careful consideration. Restricting the design considerations to the aspects discussed above, some basic design conclusions can be listed.

Select a high flow surface impingement style filter element
Use as large a filter element as practical for the application
Position the filter so the least amount of dirt and debris will be entering the filter
Maintenance the filter regularly to maintain optimal performance
Use as large of an intake duct as practical to connect the filter element to the engine
Intake duct's interior surface should be as smooth as possible
Avoid rapid changes in diameters/cross-sectional areas through the induction system
Avoid or limit the bends needed in the induction system
Keep the intake track to the engine as short as possible
The induction system should draw 100% of its air from outside the engine bay or where minimally higher than ambient air temperature regions exist
All induction component surfaces that are exposed to higher temperature components and surfaces should be made of highly thermal reflective materials
All surfaces that come in contact with the intake air should be insulated from all potential heat sources
