J'S racing Intake System

[hondar]

guys,

different intake produces different power at different rpm range

please look here many results done over various shapes of intake
link

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

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

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.

Wow let me try that:

the above statement implies....

and not anywhere in my last post

Mate - I gave arguments for both sides in my first post anyway. I can read dynos too - I research - I have been in cars with both. Get off your high horse.

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.
