Stock Intake System vs Short Ram Intake - Page 11

squidmaster · 11-04-2007, 08:57 PM

Ohhh I was mistaken that the Typhoon was an CAI. woops sorry thanks for the correction :]

I still haven't seen any dynos of CAI vs SRI though.

**ErichPryde** · 11-05-2007, 01:35 PM

in the bolt ons and all motor section there is a sticky by sickyute. it says something about tuning. he has a dynograph of the injen CAI. Xfactorwrx has a dynograph of the fujita SRI in one if his threads. either the "shocking power" or "going under the knife" thread, but I'm not sure which one.

just for my two cents i do not regret putting a aem sri on my 08 si it pulls the same and runs the same just the sound is ALOT DIFFERENT!!!! and i love it

civicRfun · 11-09-2007, 09:53 PM

Well, add one more to the SRI crowd I guess...
Just installed a Weapon R Secret with an Injen pre-filter wrap on my 07 Si sedan.
Low end feels just the same as stock.
4000 to the vtec switch is where I really feel (and hear) the difference.
I don't run up the revs all that often, so to have some extra kick at the 4k range is worth the buck-fifty I spent for the intake.

Noticed something odd though while I was doing the switch. I must of had a road kill incident I didn't know about. The inside of the stock airbox had dried blood all around it.

eeeeewwww!

Heat build-up probably won't be a problem for the next few months around here, so I can enjoy it till summer comes again

Si ya!

i was going to get a short ram from injen but now i might go with a K&N one...

i agree

you should of bought a K&N SRI

It scared the crap out of me but I wasn't about to drain the coolant to yank the entire lower intake off to get it out of there when I could just blast it out the exhaust at hyperspeed. I am pretty sure the same thing happens to anything that gets past your air filter.

There are lots of other reasons that a car with 80K miles to get oil blowby. Hell, my WRX did it right off the assembly line.

If you say so. Plastic will melt, being comprised of hydrocarbons, whereas fine dust contains silica. Try putting valve grinding compound (or metal shavings) down the intake and see what happens.

too many people are in fear of buying after market intakes. i dont really want to say if SRI are better than CAI or the other way around. but i think it really depends on if the place u live by is really wet (like it rains alot and puddles of water eveywhere u drive) or not. but i see that may people are in fear that the after market intake system would get dirty really fast and things like that. but u gotta consider the bottom line. its weather you want to tune ur car and get a power gain or do u not. its like u wanna get dirty to make ur car faster or do u wanna stay clean and not do anything? well like i said the choice is really up to the owner who owns the car. i own a r18 and im going with the fujita SRI. where i live is not extremely hot all year round. the max temp is like 100 degrees and thats kind of rare.

Ive decided not to get an intake for this reason. I am going to be having my car for a while, and I want to do as much as I can to keep it running well for a long time. Messing with the filtration is not something im gonna do. Honda built the car to last a long time while also being effiecient. Most filters are going to let more air, as well as more dirt into the engine. For me, dirt in my engine is the last thing I want in my engine. But thats my .02

The plastic did not melt. It shot right out the exhaust and hit the wall of my garage. The long-tube headers and o/r h-pipe made a nice, smooth exit ramp.

Any fine dust that makes it past any air filter is going to be insignificant and will be blown out of the exhaust valve on the first compression stroke it encounters. If the amount wasn't insignificant, we would all be driving around with blue smoke pouring out of our cars.

06RREX · 12-17-2007, 05:54 PM

^^ all of it? Then why aren't cai or sri's standard on cars like the civic Si's?

zemoffm · 12-18-2007, 02:22 AM

Ok I read the entire thread, and now I am reconsidering purchasing a SRI intake or even replacing the stock intake.

But from the sound of it, the K&N Typhoon would be the best bet for SRI, and a K&N drop in filter would be the best if I kept stock, does that sound like a fair assessment? I live in Florida, so it does get unbearably hot and wet in the summer (a problem for both SRI and CAI).

I am not too worried about dust getting into my engine; I had a generic brand SRI on my old '93 Geo Prizm (I miss it), and on THAT car I really felt that it helped, but of course my '07 SI is a completely different beast. For the 3 years I had it on that car, I really didn't feel much degredation in the engine performance, and definately didn't seem like it let in a lot of dirt (the mechanics never mentioned that the oil was especially dirty during any of the oil changes).

The dirt intake debate aside, would there realistically be any performance gain using a K&N typhoon SRI with the heat shield in the FL heat? And in addition, does adding a drop in K&N filter really NOT improve performance?

Interesting thread though... guess I'd better start getting some more money so I can do the REAL performance gaining modifications like new headers, hondata, etc...

**ErichPryde** · 12-18-2007, 02:23 AM

actually, your best bet is probably the X intake, but there is currently a wait.

zemoffm · 12-18-2007, 03:10 PM

I read the FAQ on that, but how exactly does the X intake prevent heatsoak? It definately sounded like it was quality, but after this thread, it seems like you could have the most quality parts but still suffer from taking in hot air and theres nothing you can do about it (with an SRI at least).

tommyroo · 12-18-2007, 03:47 PM

I've been waiting almost 2 years (Feb 06) to put an intake on my Si. I've been reading a bunch of stuff about my options the entire time. I also have the wet/hot Florida issues that concern me.

So far nothing has really stood out from the rest with the exception of the X-intake. I'm sure it suffers some bit of heat stroke like a normal SRI however not being made of metal has to help immensely.

Note, I still haven't purchased the X-intake either. I'm a very patient person who figures something really good has to come out sooner or later (i.e. working on brakes/suspension before speed.)

K20_Turbo · 12-18-2007, 05:01 PM

sri is definitely worth it in the winter, you dont get as much heat soak either.

zemoffm · 12-22-2007, 05:37 PM

Yea I understand that, but in florida, even the winters are pretty warm (especially in Miami), and I'm not looking to get something that I have to swap in and out. Basically, I'm looking for something with proven gains, no matter what the weather. I know thats being pretty picky, but the lack of torque in the low end on the SI kills me, its really the only thing I dislike about this otherwise amazing car. Modding wise, I'd definately prefer to start with something that has the potential to improve the performance of my car (an intake) while still being a relatively good intro to modding the SI.

From what I understand from reading this post, the stock intake in the SI is a cold air intake. Why exactly would putting in a K&N replacement filter into the stock NOT increase torque/hp? Does the stock intake just not bring in enough air?

As for the X-intake, I've seen some pictures of it, but it still looks like its placed in an area that would get hot and take in a lot of hot air. I might be wrong, and from what I hear, thats probably the intake to get (maybe after its being sold at corsport, then i'll give it a shot), but I still really don't understand how it has these gains? Or maybe everyone who uses it is from a place with cold weather.

Anyway, still conflicted.

SI_Smiley · 01-07-2008, 10:20 PM

after reading everyone's thoughts i'm so torn from a cai and sri. right now i'm either going with an injen cai or k&n typoon sri. it seems like cai's throw more CEL's than sri's. aside from heatsoak on the sri...there aren't many cons to it.

redline8500 · 01-07-2008, 10:52 PM

if i had the money or if you guys do just go buy the mugen intake carbon fiber looks some what like the stock but better garuntee that one makes more hps than any other on the market King Motorsports Unlimited, Inc.

soxfan143 · 01-07-2008, 10:55 PM

Don't buy the Injen CAI or any CAI for that matter. I made my own X intake and it is the single greatest mod to date for our cars. Where else can you get 10-12 whp for 300.00. I had an AEM CAI before the X intake and the thing is unbelievable. I've had it fot almost 3 months and It still impresses me everytime I hit vtec. I would not recommend any other intake to anyone.

The Mugen intake will not work. There is no MAF sensor housing.
