SRI or CAI

[kt_xD]

hey guys.

just wondering if anyone knows which is better for a daily K20 CAI or SRI.

thanks in advance.

[l__i__l]

yeh like nobody has anything better to do then spoon feed ur lazy ass

go search

still new. take it easy

imo i'd use sri for winter and cai for summer or you can have a go at making one of these but for a DC5 http://www.ozhonda.com/forum/showthread.php?143164-Mugen-Airbox-Style

sri is almost useless for a k20...id go CAI

thanks for your help, nice DIYthread. yeah i think it would be a cheaper option for now :)

props


sri is almost useless for a k20...id go CAI

i've been looking out for the AEM CAI reviews; they don't seem to be that bad. either that DIY or Injen i guess.

[dougie_504]

Better off using your stock box than a SRI in my opinion. Get a CAI and ignore the bullcrap about hydrolock problems. Just make sure you don't go ploughing through deep puddles/streams of water at full speed - be careful like you should be and you'll be fine. If you're in the middle of a flood then either don't drive or just disconnect the intake from the throttle body.

And search, of course :)

i've just read a thread on SRIs in the DC5S and after the second or third run on the a dyno; the people have lost around 10hp due to heatsoaking, which would pretty much bring it back to stock. In saying that i've moved towards CAI and trying decide between either Injen and AEM. They're both deliver pretty much the same amount of gains; it's just comes down to the "looks" between the two i guess (pretty ricer to think about =.=).

wtf lol please explain your logic on this mate

[SuperJDM.]

wtf lol please explain your logic on this mate

when its winter your engine bay is cooler so theres less lag im guessing?

[Mullensxxx]

think about it japan are the leaders in motor sport (with honda in mind) which imo means they know what they are doing? correct? every CAI ive seen is american, a majoirty if not all japanese brands are SRI, to me i feel that honda are all about throttle responce and being able to acellerate as fast as possible due to their lack to torque.

with that in mind besides a nice crossover and abit more power, it dusnt really seem like a CAI is really worth it, well on a honda at least. I'd be sticking with the experts and the people who designed and built the cars and stick with a SRI but thats just me.

depending on ur budget and what u like the look of, id be looking into intakes with a inclosed pod that is fed from a cooler position (j's racing, gruppe M, mugen (im not sure on k series but the b series intakes were one the of the best) id just have a good look around and spend the extra money on something good that will take u and ur car fowards not backwards.

[Lukey]

even if you get a SRI you can build a box to enclose it/block heat from it and run pipes from lower down up to the filter to feed cooler air to it

[lemmm]

wtf lol please explain your logic on this mate


winter: cold and wet
summer:hot and dry

winter:engine is a bit cooler = less heat soak,
summer: engine gets hot easier and prone heat soak

winter with cai:, you'll be dodging puddles and possible of hydrolocking
summer with sri: prone to heak soak.

winter with sri: dont have to dodge puddles, cooler weather = less chances of heat soak
summer with cai: no heat soak best thing to use during summer

kinda understanding where i'm getting at? :)

[dougie_504]

Puddles don't hydrolock your car unless they're big - at which point you should be dodging them anyway so you don't lose traction/steering or go blind from spray.

Also winter may be colder than summer but I seriously doubt the engine bay would be so much colder that it would make a difference. The engine is still just as hot and producing just as much residual heat.

This is the best option :)

yeah i think i'm going for a SRI setup, they seem easier to install also.

Why would you buy two air intakes in the firstplace when cold air feeds are better in winter and summer.. It does rain heavy in summer too you know... Heat evaporation rain.. You know
I'm pretty sure if you have a dc5 your not going to be puddle hunting anyway.. If your worried about that buy gruppeM or better yet Mugen ... Dearer yes but they are proven and make a difference..
Or if you want injen get a hydro shield.. But note this is to help prevent but won't stop it if you are going for a swim with Te car...

[azzacrombe]

Mate I reckon be safe and just get a sri. Keeping in mind your in melbourne and you guys get a bit of rain. You dont want to be worring about hydrolocking your car EVERYTIME it rains. My mate hydrolocked his car last month and let me tell you its a headache you can do without. You may loose a bit of HP with heatsoak, that can be fixed, but you dont want to loose your whole engine.

[45SET]

Hondata airbox mod, then save up and buy a Gruppe M.

Unless you plan to move the battery to the boot, and use the space that was once used by the battery for your airfilter (Much like a K-Swaped Civic), your run of the mill SRI (Not enclosed) is shit.

how the hell did he hydrolock :/ did he drive through a flooded road or something?

how did he hydro lock his car?
what cai setup did he have?

[trism]

You'd have to be driving through 30cm deep water for like, 50 meters to hydro lock a motor

[azzacrombe]

Nah man, it was just a bit of rain and there was a puddle on the side of the road. He couldnt even swerve because there were other cars around.

[azzacrombe]

I havent seen the setup on his car, but from what he told me he had custom piping which made the intake sit next to the front bumper. Not as low as the bumper though. And as soon as he went over the puddle, the engine shut down and didnt start again. Hydrolock IS possible. It just depends if you want to run that risk.

[redefine]

^how big was the puddle? and are you sure it wasnt electrical instead of hydrolock?

[trism]

An engine has to intake a LOT of water to lock. Like literally, it has to take in at least half the capacity. So like a litre of water most times. That's a fair bit.

[Jaiiiwon]

azza.. you mate got unlucky.

perhaps he was revving it as well. Noting that the more you push down on that throttle the more the engine would want to vacuum outta that poddie.
i forgot who told me.. but they said, whenever running past a puddle.. just run quick over it n keep that clutch down til you're well past it, so the revs are low.

[azzacrombe]

I dont think the puddle was that big judging from the amount of rain we had, but i guess what Jaiiiwon is saying makes sence, he was doing about 70km/h and that would mean revs would have been about 3k so at that speed he would have got a decent splash and with the revs it would have sucked in a fair bit of water.

But yeah i guess he was a bit unlucky and u have to be a bit careful if you have a cai in the rain.

[gumus89]

Even if he completely took his foot off the pedal at 70 there wouldnt be too much sucking going on.

[dougie_504]

I have had my CAI for 2-3 years now. I use it year-round even when it's bucketing rain and the water is streaming across the roads. If there's a puddle I slow down. Problem solved.

yea its just interesting to see where the pod sits
if theres undertray/inner wheel guards etc...
the more info/pics the better coz cai doesnt have to be heaps close to the ground... just out of the way of as much heat as possible

[NightKids]

Screw changing your driving everytime it rains, just get a Gruppe M already

[typ35]

mate dont listen to everyone that feeds you negative comments about sri's. i have a type s, n just recently did a diy job for an sri. throttle response is about the same, and even if there is a power loss up top due to heat soak, cant tell much, coz theres a noticable increase in torque right throughout the rev range, n the best part of it was, i did everything for $90! its really not as bad as everyone makes it out to be. i was in the same situation as you, deciding injen or sri. ended up sri, as its easier to replace the filter, absolutely no chance of hydrolock, and u cant beat the sound! :P but, in the end its up to you, obviously a cai, has greater benefits than sri, but for daily driving imho, sri isnt bad at all

Anyway, OP, grab a CAI and you won't regret it.

Only recently you say... in the middle of winter you say...

Wait till summer hits, you'll notice the lose of power.

i know wat u mean man, i had a pod on my previous car. but even with my stock airbox, i could still feell heatsoak and the sluggishness of the car, so an sri really cant be that bad compared to stock. obviously when it its hot, no car will run at its optimum, but then there are those cool summer nights to look forward to, whether you have an sri or cai. but as vtec screamer said, sri's are for the poor, i definitely agree to some extent. but it is also cheap and very cost effective.

The first aftermarket intake I had on my car was a SRI.

Totally agree with the noise it made (It is awesome!), but I wasn't happy with the perfomance. A couple of weeks before I bought my Mugen intake I actually took part in a Honda Dyno day. My DC5R got 116FWKW for its first run... it then backed up with a 114kw run... then a 112kw run. Every other car on the day was getting consistant figures for each run, so this is when I (And everyone at the Dyno day) realised that having an exposed pod filter sitting right above the gearbox, and next to the engine wasn't a good idea.

Listen man, these threads and this forum are here to help people. I know there is another HUGE thread for cai vs sri, but the fact that there are 42 comments on this threads means that everyone over here wants to help out people who need it. If you dont like this thread or if you dont want to help, just dont comment. Theres no point shrugging off other people with your comments. Your just messing up your own rep.

I just bought an injen for my DC5R and got it installed last week end ... it is heaps better now especially at top end. When it hits vtec the intake roarrrrssss. It's an awesome sound! definitely back for bucks and good gains..

[MingZai]

Certainly CAI!

[meatball]

save up for a gruppe M

[Nepolian]

Regardless of what people say, an Sri is a good beginners upgrade, cheap and noticeable! I say go for it, I'm sure that if you're not sure, someOne here from your area!

[khanguskhan]

Well I have SRI for my dc2r and at the moment looking to get a fabricated air feed into the bottom half of the pod its going to be pretty big would that mean I get the best of both worlds? 360 degree air intake as well as a feed of cold air to at least 50-60% of the pods surface area?

[Nepolian]

Khang, from what I've seen, just run some extra pipes into the bumper and make it pretty much a CAI.

[khanguskhan]

Yep pretty much what I'm doing but it's going to be 1 big one, will put a photo up if it turns out good :)

[dougie_504]

I started with an APC 3" SRI. Then went to SCA and bought a silicone 45deg bend + a small length of aluminium 3" pipe so I could whack it down where the resonator was. Two extra hose clamps is all you need.

It's much better than it was in SRI form, and given that I paid $70 for the SRI and like $105 for the rest of the junk it was a good little first project.

116 fwkw just with the sri?! was urs a diy or a brandname??

K&N Typhoon.

The emphasis should be on the KW loss after each run… not the power it made.

[xenonkuraz]

For the difference in power from SRI Vs. CAI without any accompanying mods I'd stick to an SRI for it's ability to provide you with better fuel economy.

Warmer air = better fuel atomization

Going with a CAI instead would net you probably 1-2kw extra which is 100% unnoticeable.

[dougie_504]

The fuel consumption difference isn't noticeable if you drive your car mildly to optimise fuel economy. Keep it 3,000RPM or below and you'll be in the same boat, SRI or CAI.

here are some nice intake systems. simota's a good brand.

hmmm, i know what you are saying, but that being said, i was driving last night and the outside air temperature was around 8-10 c, the car felt lyk it was surging through the gears much more quicker than stock. i really think a dyno cant predict the amount of power, because theres no airflow streaming into an sri, whilst stationary. my sri is positioned soo it sucks air from the gap in the wheelarch, and im in the process of getting a heatshield made, to stop the heat from the headers and the transmission from entering the pod. i think that would make a massive difference than having an exposed filter in the engine bay. i went for a drive in a mates dc5r with an injen, i honestly can feel quite a difference in performance in the top end, but throttle response wasnt the same as the sri.
