Some companies offer only short rams intakes for some cars because they don't see much effect with CAI's...but that lack of change in effect has nothing to do with how long the tubing is or where it's routed.
When you are WOT the butterflies have almost nil restriction. This has been discussed more times on more forums than you can count. Until you have PROOF that it DOESNT work, maybe you should keep your opinions to yourself, because thats all they are.

Listen, I've lived in over 10 different states and 3 different countries, it gets 90 about everywhere.

Metal pipes are still INSIDE the engine bay and subject to ENGINE HEAT. I don't care if its 60 degress outside, once its sucked into a metal pipe thats 180 degrees and then sucked into a ******* turbocharger it makes about as much power as anything else.

A buddy of mine that fly's B-52's said he did an excersize at the acadmey a while back with his car and to see any effects of the RAM Air Intake you would have to be going +150 MPH...I doubt most people do that in a race...unless they've got a good car!

That's awesome...tell me to supply proof when you have none yourself?

Ground can get that hot...metal can get that hot...stuff sitting in the sun can absorb energy and get that hot...but there aren't many places that see air temperatures in that area.

Metal pipes are still INSIDE the engine bay and subject to ENGINE HEAT.
OMG!! I'm so glad you've told me this because that intercooler and tubing can save me at least 15lbs!!

Actually, I would like to look over this last little bit. I don't disagree with the lot of it, but this, yeah kinda.

.

Heat wrap...If it's 60* outside, and 180* on the inside, I'd say the air getting to my turbo would be around 100*. Which is still better than 180* from you're "ram air".

Wrap a ram air. You'd get the same effect. All I'm sayng is that the 2 are fairly close when compared side by side and to shoot one down as 'rice' is just plain ignorance or stupidity.

yeah wrapping a ram air will get zero effect...it's still drawing in engine bay air.

And insulated CAI would have a slightly lower temp than a bare CAI.

does drilling a hole for cold air intake have any negative effects on rigidity or anything? I'm sketchy on drilling giant holes...

On the topic of Cold Air Intakes, does anyone know what happened to Checkpoint Engineering (www.checkpointmotors.net)? Their CAI was pricey ($250) but it looked to be the best in terms of quality that I have ever seen mass produced. I'd recommend it to anyone interested in a true CAI but their website no longer exists.

You're the one talking out of your ***, and I didn't insult you to begin with so don't be talking smack to me buster.



You've furnished no evidence to support air intake tuning forward of an AFM. There is NO tuning to speak of after the AFM all that's needed is the least restriction and the lowest intake temperature possible.


Residual cooling will take effect down the entire length of the intake tract using a true cool air intake(a.k.a. CAI) compared to a rice-boy short-ram intake which will do nothing nor does "weapon R" bring to the table any data independant or otherwise.

How does that thing get air?

Also, just to point out, you guys know that the STOCK intake is a cold-air intake, right?

From outside? I have it and it does just fine tyvm.

Also it isolates the filter from the engine bay.

I certainly wouldn't say "most", but what difference does that make? HKS are just as guilty of BS marketing as anyone else. Some of the stuff they write is hilarious. It doesn't change the fact that when applied to most of the aftermarket stuff the term "short ram" is completely bogus. If you want to see a true short ram intake system go look at an open-wheel race car.

This statement shows you don't fully how resonant intake tuning works. In a system where all runners are fed by a common TB, all of the tuning takes place in the individual intake runner length, not the plenum, TB or intake duct.

Some companies only offers SR's in some cases because there is no advantage to using the CAI.
Companies offer a filter on a pipe because it's an easy way to make money out of kids who want to modify their car but don't know much about it. There is always an advantage to sucking air from outside the engine bay compared to sucking from inside it.

When you are WOT the butterflies have almost nil restriction.
Totally untrue. All throttle butterflies cause restriction even when fully open, and it's not "almost nil". But that's irrelevant because throttle restriction has nothing to do with intake tuning.

This has been discussed more times on more forums than you can count.
So now forum discussion makes something fact? I prefer to get this sort of technical info from far more reliable sources, like technical books that have to stand up to far more rigorous standards of proof and are written by experts in their field, not people who get all their knowledge from internet forums.

Until you have PROOF that it DOESNT work, maybe you should keep your opinions to yourself, because thats all they are.
And your opinions are more worthwhile? Where's your proof that it does work? I guarantee you that'll be harder to find.

Metal pipes are still INSIDE the engine bay and subject to ENGINE HEAT. I don't care if its 60 degress outside, once its sucked into a metal pipe thats 180 degrees and then sucked into a ******* turbocharger it makes about as much power as anything else.
No, it doesn't. If air starts out colder, it will end up colder. It's really simple. Even though some heat is picked up from the pipes, the turbo adds heat and the IC takes some away, if you suck in cooler air from outside the nett result is cooler air entering the engine. You only have to look in the engine bay of any production car or race car to see that people a lot smarter, more knowledgeable and more experienced than you believe the exact opposite of what you claim.

Do you need numbers? How about the fact that the density of air heated from 70degF (an average ambient temp) to 110degF (an average engine bay temp by my measurements) drops by ~7%. This figure isn't a guess, it comees from a psychrometric chart (look it up). What do you think happens to performance if 7% of the oxygen and fuel is removed from the equation?

Because you don't get air stock from those locations that are covered with the box, it comes from under the hood into the box. I don't see the problem that you do?

I have one and it works just fine FYI.

How can it come from under the hood? The hood's sealed all the way around (or should be)...

You might be getting some air from outside via the headlight scoop (unless the headlights are up of course), but a big chunk of the air entering the filter will be hot engine bay air. It is nowhere near sealed off enough to ensure no engine bay air gets in. Good idea, poor execution.

I don't really get you, how does it get into the stock air box? That's sealed off?

Once again I own it, and it works just fine.

Cold air gets into the stock air-box through that piece of plumbing that hooks 90* off the box and snorkels over the radiator brace.

Once again I own it, and it works just fine.
That's all fine and dandy I just want to know how your box is getting fresh air. I'm just curious, man, that's all.

I thought that upgrading your MAF sensor would be better than a CAI.........
