CAI vs SRI: PLz Vote!

[BremertonMSP]

So what? Prove that the small dif. in temps equals to a better horse power.

Colder air = denser air. Denser air = more power.

So the 15 degree difference between the SRI and the CAI are going to make a difference once it flows through a 600 degree wheel?

Its not.

Unless you replace that Intercooler, it really doesnt ****** matter.

WTF are you saying? All I did was reiterate what funnylittleman said on the 1st page. Some people just don't understand that the FMIC cools the air, not the CAI. I actually prefer SRI in all situations, but I know the CAI has good #s, so if you aren't getting a FMIC, you might as well get that.

When it's colder outside I'm going to take a guess and say your car feels a little more responsive. Why is that? (huh)

The difference between the airflow being pulled through the pipes of a SRI vs. a CAI is extremly negligible. Though, a CAI will always pull in colder air. Just get an Injen and let your atmospheric conditions tell you whether to use it as a SRI or CAI.

The stupid thing is that EVERY CAI that is currently available uses metal hardpipes, which absorb heat like a mofo. I'm sure that any colder air advantage is almost negated by the heat soak of the intake pipes (our engine bay is hot as sh1t, remember). If someone offered an intake made from silicone pipes or hardpipes coated with Jet Hot or w/e the hell it's called, then I might be inclined to think it does something.

There is a reason why these IC pipes are coated:

People are dumb...if they had any sense, they would talk to their buddies with other turbo cars & know what to go with.

 

[BremertonMSP]

This is simple...

If you're not getting a FMIC--->CAI

If you are--->SRI.

I do not agree. For one reason, a FMIC has better heat transfer then the stock IC. Some of that warm air is going to travel under the car, but some is going to travel into the engine compartment where the SRI is going to suck it in.

FMIC is what cools the air geniuses, SRI increases the airflow.

Look, by the time the IC comes into play, the turbo is spooling up and sucking a sheet load of air in. The imagined restriction of an exta foot of pipe ain't gonna make a hill of bean difference.

I don't understand why everyone thinks that the length of the piping in the intake, or anywhere, makes a difference once the motor is on. There is so much velocity moving the air that the length doesn't matter at all.

Okay, I deleted the pic out of my response because the thing was huge.

So you admit that our engine bays are hot as sheet right? So hot that it heats up the pipe on the CAI. Now, if it's so freaking hot in there, why in the world would you want to suck that hot air directly into the engine?

With a CAI, you are starting with cooler air. While that pipe may be metal and absorb some of the heat from the engine compartment, the air traveling through it is going so fast it doesn't have time to pick up much of the heat. Also, only the boundary layer of air next to the pipe is going to be heated, not 100% of the air traveling through the pipe.

Why do you think IC's are the way they are? Lots of surface area to transfer heat.

Everyone is making it sound like it takes massive effort to pull air from the intake. Once air is already moving, it isn't a strain. But whatever. Look at some of the turbo kits out there, the piping is all over the damn place.

I tell you what... make a pipe that slightly bends up and over towards the front of the car from the intake manifold... put a hole in your hood with a little filter to keep the s*** out.. and then call it a day. Cause if you are counting on the minimal gains you are gonna get from an intake on a protege then you need to just save your money.

LOL!! Good point! And look at the yards of extra pipe people add when they install a FMIC! No one ever mentions the power loss, or the heat being (supposedly) absorbed by all the post fmic metal pipe.

This is the way I am going to install my SRI so that I get the best cold air to the engine.

I emailed Injen in regards to this to see what they have to say about a CAI vs SRI on the Mazdaspeed:

"We made the CAI and designed it on the dyno. We found it to have higher
gains than the short system during our independent testing, that is why we
only offer the cold air."

In other words: "We feel that the gains are so minimal between the two, that we dont want to take away sales from our higher priced CAI."

You obviously don't own an Injen CAI/SRI
