CAI vs SRI questions

[atruhondagrl]

I know there are a million threads on here regarding the CAI vs. the SRI which is more powerful, better, yada yada yada. I'm in a massive hurry and I need to get to work so I can't search for them right now. If anyone has a subscription to one can you post a link here on it? Please!????

I'm trying to decide if I want to get a SRI. I'm debating between INjen or Fujita. I've only owned AEMs. I have the CAI but after it burped on the highway yesterday I'm paranoid.

I'm utterly convinced that Pennsylvania is turning back into a primordial rainforest.

I just started reading about this last week. And I'm a little surprised you don't already know the answer. A CAI is more powerful than a SRI because cold air produces more power than hot air becuase it's more dense.

I'm still waiting on my Injen CAI to arrive.

Now that I've read your post again, I'm not sure what you are asking for. :)

well I see the same stuff you're seeing. I was driving home in Montgomeryville thinking I'm REALLY glad I don't have a CAI. If you don't want to worry, I'd say keep 'er stock and put the money elsewhere.

[atruhondagrl]

Huh? OMG. I did ask that question. God, I'm such a dumb a**. Where's the icon for embarassment? I do know the answer. I was in a hurry before I left for work.

Mostly, what I want to know and what I should have asked is, is the SRI worth it? I love my CAI and it does have the power I need but this relentless rain has me freaking out since yesterday. I don't understand how it did that since I didn't drive through any puddles and I was on the highway on a hill. I'm at a loss. I've never once had the car do that but it's never rained like this since I've owned it.

I got the CAI put on a week after I had the car. Never had a problem till now and I've driven in bad rain before.

Hey, You're just down the road from me. I'm in Allentown.

peliROJO, you rock and I love you . Please don't hold my brainfart against me. THanks for all the links.

My boss is at a meeting and he'll be back in 9 minutes so I gotta go. I'm going to read these from my palm pilot. Sneaky sneaky. Thanks again.

I live in Hatfield which was totally swamped yesterday. It was awful. I just hate worrying about my cars. One of the guys in here was reporting some erratic behavior with his injen SRI - so heads up. I don't think it was anything unfixable. Someone suggested he reset his ECU to take into account the new intake, which i thought was good advice. you might want to monitor that thread. or if you can't find it, say so and I'll look it up. good luck!

[atruhondagrl]

cool. thanks.

[pengful]

Do you want to hear about the rain in Asia? I've been thinking about CAI since day 1 and still haven't got the guts to install it, thanks to all the horror stories here.

Hmm... still thinking....

This is true from a theoretical perspective. But, show me dyno results to back up your assertion.

For example, the largest gain of hp and tq on a stock 350z comes from a SRI and not a CAI. ( My previous car.)

Well I think it's pretty safe to say we're assuming we're talking Civic here, not other cars. I believe there are numerous dyno graphs showing the advantage CAI has over SRI in this context.

[peliROJO]

No problem. I'm sure I'll be asking a question and you'll have the answer. You seem to be very knowledgable and your Si looks great.

Thanks x 2. I love these cars and mine is a work in process.

Show me a Civic with the R18 on the dyno that has alternately a SRI and CAI on the dyno run. Then we'll talk.

or you could go look yourself to back your points instead of deferring to me. first off, i don't know about the R18 since I don't own one, and second, the girl who started this thread is rolling in an SI. if you want r18 figures you can go ask your secretary to "show you" and you can discuss it with her.

AEM's dyno for their CAI (not V2) showed a 7HP increase. They're SRI isn't completed yet for the '06 SI.
'06 SI w/ AEM CAI: http://www.aempower.com/pdf/dyno/21-...-Si_CAS-HP.pdf

For the EP3 SI's, the SRI underperformed the CAI by 1-2 HP.

Does this prove anything about the SRI vs CAI for the R18? No. You can go look around the internet for dyno graphs.

Does it prove that the AEM cold air systems will outperform the short intakes? No, but it definitely suggests it. Cold Air > Hot Air.

[gbae007]

I'll wait for independent dynos and let you be the fanboy for AEM.

[skittleslegend]

For the record, the Injen intake and the Fujita intake are essentially the same thing. That's why they look similar and why they have similar advertisements. Injen is the parent company of Fujita. = quality shizz...

and what's with people starting shit? Grow up. Geezus....

The original poster has an Si, as do most of us. If you want numbers for the R18, ask for their dynos and leave the bickering elsewhere.

ok dude - you give the guy a hard time about endorsing CAI over SRI, and then you retort with a blanket statement about how it's "good in theory, show me the money...garbage garbage"

but that's the best you can do?

I certainly am not a fanboy - I said already, I think intakes aren't worth the trouble, so don't come at me with that crap. I don't have an AEM, and I've never installed one on any of my cars. In fact, I had a DC Sports SRI on my Prelude and I can guarantee that in most driving conditions, I lost performance because it was sucking in all the hot air from the bay. So what can you say about that oh wise one? If Short Rams are better performers IN GENERAL than cold air systems, why at the drag strips do I see people:

ICING their intakes

and not

Heating them?
