CAI vs SRI: PLz Vote!

[II-Savy]

yup agree with that one. i dont care what ANYBODY "tells" about there expereince. put a stock car on a dyno, put the cai on get back on dyno, put sri on get back on dyno. Until the NOBODY will know which one is better.

img going to try something with my injen when i get to the dyno, i have stock dynos, then ill dyno with the injen, and then do the sri mod that people are doing to the injen and see which one is better. until then word of mouth is exactly what it is "word of mouth" and not PROOF.

Holy cow, yea I would argue with science also. You can never be too sure about temps and changes. Jesus it's logic guys. With the CAI you START out with a colder charge, period. It's very simple.

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

The one thing I looked at was just some guy's personal site, the CAI made 4 more hp than the shortie. Can't find the site though. Oh well, whatever. Slow is slow, buy an intake and be...well...not as slow...well...yeah slow...(silly)

the air may "start" cooler but it has to travel a longer distance. longer distance = more work for a 2.0L 4-cyl engine. there isn't enough pull to move the air along fast enough to keep the temps down. so now the 20 degrees cooler has heated up another 10 degrees and your motor had to work harder to get it. SRI = CAI = SRI on our cars. maybe there's a reason that no one can really feel the difference between the two on the proteges...

Things that are cold are dense. Colder air is more dense, thus putting more air in the motor. Middle school science class was hard! (silly)

To question opinions and theories is wise; to quarrel with facts is foolish.

I have yet to see any facts in this thread.

CAI do result in slightly cooler intake charge temps when reaching the throttle body. Wether or not it's enough to make more power is up to debate. With what you're saying then the weather outside shouldn't make a difference on how a car runs, because it all hits the same temps when it enters the motor anyway right? (confused)

Cold air is more dense isn't a fact? Okay....

 

[SpeedMcheen]

Yes it IS a fact. The colder the air the more dense the air. Simple physics.

That's why I posted it. Let Ceej know.(silly)

The extra pipe is a very short distance compaired to a SRI. I don't see the engine having to work harder to pull air through.

Dude your just not reading. Fact is YOU START WITH A COLDER charge. That's a fact, another fact is that colder charge is better. Period.

Ahh, well i guess I misinterpreted your misstatement, or question, or whatever it was.

 

[freekwonder]

but like Dan said. it may be colder, but with the cai in the engine has to work harder to get the air to the TB.

nobody has PROVED that the cai is better then the sri. physics works on both sides of the matter. the cai is going to be cooler, but the sri isnt going to work as hard. all im saying is science is great and i know sjack hit about it. but one thing i do know is proven on a dyno power, or proved at the track power. until somebody shows me test showing the CAI or the SRI makes more power. or runs at the track that the CAI or the SRI took more time off of there 1/4 mile time, then im going to ignore the science behind it, cause it could be used to prove both side of the question.

as soon as i can get to the dyno ill post them up here.

With a longer intake tube it might be helpful for building velocity to the airflow. But I have ZERO facts to back that up. The main reason I have a CAI is i hate having a big ass filter in my engine bay.

Once you go through that hot turbine wheel with that small IC, it won't matter.

This is simple...

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

If you are--->SRI

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

I'm going to get a FMIC for my NA motor. Pimp(mj)

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.

 

[SpeedMcheen]

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.
