Dyno Science: "CAI" Box vs Open Cone Intake



that's also 100% wrong because when youre moving the temperatures drop to ambient or maybe a degree or two higher.

I managed to combine "open cone" & "Boxed CAI" with a homemade air box made out of a rubbermaid plastic storage container. Works greatand cost about $60 to build.

should also remove that engine cover!
 
someone pointed out to me that the dyno data could easily be faulty. when the dyno tests were done, it was likely that the hoods were open right?
so that would totally throw off the data... it would be different with a closed hood keeping the hot air in right?
 


but who cares, even with the hood closed there is lots of air moving through the engine bay so long as youre not sitting at a stop light.
 
I would like to see the numbers on a stock intake.

This has been a debate over on over forums for years. Intakes add a few horses but nothing major.

I would like to see if my velocity stack adds a few more horses over the standard intake...maybe once I'm tuned and I am just playing around, I'll go to the dyno and compare stock vs standard vs velocity stack.
 
Im with drunkie.I would also like to see exactly how much whp is gained over a stock intake versus like a fwi or open cone or even a cai.
 
intakes dont make power, they allow power.

you only really need it once you start getting to smaller pulleys where the flow is necessary.
 


I have gone to an open HAI intake from my ZZP CAI since I threw my IC on and either a lot of you supporting the HAI have no idea what you are talking about or are just lying. When I had my CAI I was always within 5* of ambient temp when cruising. Now with my HAI its usually 40* higher on the dot than ambient temp, its ridiculous. Let's hear it :)
 
But when your moving...the temps go down. Flow> Ambient Temps.

Which is all that matters...who races in traffic when your car is heatsoaked?

Not I.
 
yay finally a some proof on paper! sadly I'm sure someones still going to try and say else... I figure the open cone always flows better because it can draw air more easily than anything else which why I will not get a box for my gtx hood... Yea it might be ram air but I'd have to be going like 90mph+ for it to really do anything

Both. I cruise on the highway for about 20 minutes everyday each way to and from work, it stays 40* above ambient. In town is even worse, usually about 50*.

When flow isn't effected why not have lower intake temps?

Who races on the freeway anyways? Besides ricers of course. Pretty sure you don't get to cruise around at the track before you run, and from my experience that doesn't lower intake temps anyways.

Continue :)

Agreed, but I bet a stock intake will be within' 5whp on a full bolt-on/rockered/3.4 setup.

this is probably true.

so regardless of the higher intake temperatures, are you making about the same amount of power with a way cheaper intake with less parts? i would say you are.
 
Couldn't say. I just can back in here after I saw your post higher up on this page about a HAI being within a few degrees of ambient temp and it made me lol.
 
Because when your moving...it does sit within Ambient temp...my intake temps (when moving) never get more than 5*~ of what it is outside. I've never seen any interesting reasons to spend another $150+ to gain you nothing.

Ricers race on the highway...which is why all of your videos you posted on here are highway runs ;)

I yank the headlight...and wait for it to be cooler before I go to the track anyways...I'd never waste money on a hot day.
