hey guys, im just wandering if you could help me - driving a Integra DC2.
im deciding on an Apexi intake system or an J'S racing intake. JS is more expensive due to carbon. Though is there any big difference?

i know that the Apexi intake gives a nice sound. has anyone experience J'S intake?

I got the copy. Its fantastic. Not sure what the power gains are but there is definately a difference. Free revs much better now and feels/sounds like its breathing better.

Does your DC2 have abs?? Cause your ABS unit might be in the way.

j's racing made one special for dc2 with abs..
different to ek / eg

yeah its a perfert fit. but im just wandering abt the 2 difference's. is it worth the extra $$$$ ??

also the quality of sound? is there big sound difference between Apexi and J'S racing ? which one would u prefer?

You are talking about intake system right ? not a subwoofer or tweeters ? hehe.

anyway J's produce a nice sound + response better than apexi

Yes but what about the heat soak you get from it.
This is one of the dilemmas i think about (and what is stopping me from puchasing one)

custom heat shield box bro.
I personally had one myself and did a qik airbox/heat shield for it.

I'm also using the apexi with a custom box around it.

If you want the best of both worlds, get the J's racing intake, and put on an Apexi filter at the end. Just make sure you have enough space as the Apexi filter requires an adapter.

i think dynodave has dyno'ed the J's racing intake system before... u dont make much gains... i recommend u getting a long ram intake, like plazaman ones as it has proven gains already...

hey guys, thanx for ur posts! appreciate it. i actually went for the JS Racing. i went for JS because its $100 extra - i get an carbon fibre tube!, a much greater responce (looked at graphs) and the noise factor. its all worth a little extra.
thanx

I have a genuine J's carbon intake on my car and I wouldn't use anything else. Feel fantastic and has a definate increase in power over stock.

My personal opinion with this intake is it's design - it causes air to be sucked towards the manifold with more velocity. The "whale penis" has been copied numerous times - there is a reason for that.

but the throttle body end is still the same size as the standard one so the velocity will be exactly the same

EDIT: unless there is more air getting sucked into the intake, then there would be more air trying to get thru hence a higher velocity, hmmmm

With the stock intake arm, there are times when the vacuum is there in the intake manifold to draw air in, but there is not enough air flowing in the intake arm to satisfy the amount that is required.

The large volume and smooth curved design of the J's Racing intake tries to maintain the amount of air available at full throttle and high RPM. If you have an MAP sensor, you should get readings closer to atmospheric pressure with the J's racing when compared to the stock intake arm with a pod filter.

I've seen a clone J's racing intakes on several different cars now, not a single one of them made as much power as they did with a long ram intake, as tested on the same cars.
-It made less power on my car than the modified stock airbox.

I'd be interested in testing a genuine article on the dyno... They look nice and sound good, not a chance in hell I'd consider forking out for one without some back to back testing though.

Any dyno results and was this with enclosed airbox with cold air feed or was the pod open to the engine bay heat?

ginganggooly

In all instances, the cars were dyno'd with bonnets up. Heat soak was not an issue.

It is to do with the length of the intake. The short-rams and J's racing style intakes are too short.

Yes it has been proven that the AEM Cold Air intake makes more power than the J's Racing intake. However, the J's racing intake increases throttle response (and sounds sweet in vtec!).

I wish I had those dyno charts when they did a generic short ram vs J's vs AEM 3" Cold Air. The AEM made a few more peak WHP at the end of the rev range, but the J's had the best midrange.

The long ram intakes i've seen were louder than the j's racing style intakes too :)

I can't comment on throttle response as I've not driven a car with a J's racing intake bolted in, but if it's anything like any other shortram, then the throttle response effect is probably a by-product of the placebo effect ;)

gingangooly, can you post the dyno printouts or direct to a website with them? What figures and shapes are we talking here?

guys,

different intake produces different power at different rpm range

please look here many results done over various shapes of intake
link (http://www.tprmag.com/issue/1/1_intakes.shtml)

no intake conquer all rpm range. get one that suit your needs.

from my personal point

i like js racing or comptech/ mugen box system

the cai system (sucking from the vender) is cool as well but i have two problem with that. it gives people this phobia of water sucking everything they see a puddle of water. why should we drive in fear of water?
second, i used to have iceman intake in my car . it is a cai, it is hard to clean (need to remove bumper) and sucked all the dirt.

except for these 2 reasons. i think cai is proven to be a gainer on mid-range.

i have tried 3 different system on my car just to let people know where i based on my info from.

honestly all system has their advantage and disadvantage.

on personal note:
i sold heaps of js racing intake, people has nothing but praise for them.

someone should give me a rep for this.. lol :D

I bought my J's intake for throttle response and a bit of mid range gain. Yes, it's true, a long cai WILL give you more horsepower - however this is a number. Great - you made 2-3 more hp than me at 9000rpm. Good for you!

I, myself (and let me just make this clear that this is MY OPINION), would rather have more usable torque down low in the rev range where my B16 is lacking. To me it depends on what you want - my car is a street car and will always be a street car and my daily driver. I want usable power.

Just installed my J's racing intake about 2 weeks ago.
The butt dyno says that there is definitely better throttle response.
The induction sound that it makes is freakin awesome as well.

But after a long drive, I opened up the bonnet to see how hot the actual chamber got.. and it was almost too hot to place my hand on. So that could be a problem if you're looking for some extra horses.

I'd still recommend it though.
It seems like the engine revs more freely and also gives better response.
Thumbs up to J's racing tsuchinoko intake for everyday driving!

pros: everyday usability and bling!
cons: does get very hot - heatsoak but I cant really feel the difference as I had K&n filter on the end of the stock piping without airbox.

your engine ambiences is hot is your at a stand still.

the temperature will be about the same once the car moving at a momentum (travelling on the road), ie temperature inside the bay and the atmosphere

that is why you have radiator mounted in front of the car as cooler air will enter from the front. and it goes inside the engine bay and it exit from the end of the bonnet (nearer to the firewall)

Unfortunately there are no graphs on hand...
However, there are a few testimonials as several OH member's cars were tested- OB (built b18c2), fatboyz (stock b18c7), notorious ahmie (stock b16b), my car (stock b18c2 - tested many, many systems on my car). Also tested out the same setup on a black top 4AGE corolla. Every car had a similar inprovement, I believe the improvement for b16b in ahmie's was up around 10kw...

So, you're correct it's just a number, but the number is getting towards the point of being reasonably significant...
The entire long ram graph was stronger, and there was also a pronounced hump in the mid-range with the long ram, making it IMO vastly superior to the j's racing intake. So in effect, you LOSE mid-range with a j's racing intake- when compared to a long-ram.

A percieved improvement in throttle response does not, equate to an improvement in mid-range torque, and therefore power. If you want overall better performance you need an airbox with a modified induction path, or a simple long ram.

In terms of hydrolock, yes, they can be a worry... However, if you have your splash guard in tact, and don't try fording any flooded areas that are more than about 20cm deep, you'll be fine. I had the CAI setup in my car for about 12 months, and never worried about it in any kind of weather...
Lastly, it'd be worth bearing in mind the visibility of a short-ram setups- while both long and short rams are illegal in nsw, the long rams have the filter tucked away from view behind the bumper.

^ OK that's good mate - but my "percieved" improvement in throttle response isn't just talk. I am saying that my throttle response was GREATLY increased. Yes yes, bum dyno whatever you wanna say, but this is something I noticed after my first drive with the intake installed. I don't talk shit.

And I noticed this mostly in mid-range. Therefore this, to me, is more usable mid-range power.

In the context of the current discussion, the above statement implies that a J's racing style intake will yield superior low-mid range power than a long ram. The testing myself, dynodave and several other forum members were involved in really flies in the face of your "opinion".

So, you're welcome to your opinion mate, just don't forget that your opinion is not based on any comparitive analysis between a long-ram and short-ram and your opinion does not include any quantifiable results.
You're not the first person on these forums to think that their inner ear is a satisfactory mechanism for benchmarking performance; it's not.

In summary, I'm not saying you're talking shit, but- alot of time, money and effort went into the testing of various intakes over the last few years, and it leaves sour tastes in the mouths of everyone involved in the testing when someone else comes along and says that their opinion counts for as much as the extensive dyno testing that was performed.

Peace out :thumbsup:

Yep - and not anywhere in my last post am I comparing a J's intake to a long ram. I've just posted my experience with the intake. I'm not trying to say it's better than any other intake, but I'd rather not have to worry about hydrolock and for a short ram it does the job nicely.

And yes I'm aware that my opinion is not based on any analysis of comparitive dyno graphs etc.... because I wasn't comparing. And since when am I saying that my opinion means more than dyno graphs?

Sour taste? Eat a mint.

Why are people sooo touchy with their intakes damn it.

My j's intake puts a smile on my face, and thats whats important to me.

Some people may have a kw or two more then me but who cares. Its not like that extra power is gonna be pullin car lengths on me or anything.

Damn guys, settle down.
