I have been wondering for a while what type of gains the j's intake would have with some real cold air going to it.

basics:
95 gsr with built gsr motor (right now only 170~whp)
itr tranny with comptech flywheel and ats fd
stock gsr exhaust with comptech header and untuned engine with base fuel map on the hondata.
I cant really afford to be spending 300+ until I have a stable job again, until then no more car parts I dont really need.
tires are kumho 712's

I took off my headlight yesterday. So I could run some ducting from my headlights to the intake. Well I had a bunch of stuff happen over the weekend, so I did not get around to run ducting to the intake. I currently just have the whole light housing out.

I took off the fake carbon fiber cover that goes over the intake too.

I am in bay area. Tonight it was around 40-45 degrees F

before with first gear, I had minimal traction problems. On a cold night I can chirp tires from 2-3 as well.

Tonight the engine was loving the cold air.

First gear was a total wast. I could not get any traction, even with 1/2 - 2/3 throttle.
2nd gear was still a big lack of traction. I would shift, tires would try and get traction but still keep spinning till 55-60 mph (end of 2nd)
2nd gear was absolutely the most fun. The revs were extremely fast and vicous.
3rd was fast, but not really fast. I think the problem is that since my cam gears are still set at 0, 0. and engine is untuned. The power is not there at the perticular rpm that the 3rd gear sets it at when coming out of 2nd
4th. Honestly pulled as hard as my gsr tranny in 3rd gear.
there was a LOT of power from 5.5k to 8.5k rpm. The car felt like it was at a lower speed from the feeling a lot of tq. Even though I was at higher speeds.

The j's intake was really nice before. Very fast throttle response. Better than my old aem and comptech ice box setup.
Tonight was both instant throttle and instant power. With normal setup, the j's was just fair at power. The engine completely was transformed into a much faster motor. When I hit the gas above 5k rpm, the rpms climbed really fast and instantly pushed my back into my seat

I had to force myself to go back home and park the car, because I would have been out there all night if I did not have stuff to do.

I am curious to see how the mugen intake compares. But I would have to say, if you are willing to loose a passenger high beam, and run ducting to the intake. Then you will be very happy.

I am sorry that I dont have any factual data, I will have some up next month, when I get my hondata g-sensor to go with my s-200

edit: changed c to f. it was late when I typed it up.

nice! makes me want to lean towards the J's again...

 

J's + cold air. hmmmmmmm.....

I should have my setup done by the new year. Pics to come...

 

V2

 

Hey, I'm curios. Would the J's Racing intake be a better intake than the AEM Cold air. I'm currently running an AEM short ram , but want to upgrade, but before I do, I want to know should I get the J's racing intake or the AEM cold air. Also will it work with my Skunk2 manifold, and a soon to be installed 68mm TB. Thanks, ( Sorry to Post ***** ).

 

Whew! If that's what you call a cool night I'd hate to see a warm one.

 

I was going to try and make something that would pull cold air into the J's, but never did. Something similar to the mugen intake arm that goes down into the fenderwell. Oh well, I'll have to try what you tried.

 

Bob DC-2,

We should have maybe 5-7 people pitch in for an hour dyno session at Atp in Fremont with a different intake set ups. Test them on different motor set ups and find out which is most beneficial. I run a K&N drop in with oem air box with a home made tubing in place of the resonator I made 191/133 after tuning(of course more mods). I'm hoping to get the V2 to see if that it is truly better than the 1st aem cai.

 

I'm still working on cutting a hole in my headlight (EK Civic) so the airflow goes directly to the filter/j's intake a la Techno Pro Spirit style.

The result should be quite good although now i'm getting lazy and leaning towards getting a Mugen. heh heh

 

once I have the hondata g-sensor. I will be able to make dyno runs by just driving it.
I am up for that, budget wise I cant make it happen for another month. I have no problem donating the intake for a day

 

Why do people think that being able to chirp tires is an indication of the power their motor is producing? Yes, when the air temp decreases engines generally produced more power due to the dense air. However, with colder air, tires become harder and consequently they loose traction.

The ability to spin your tires deals with so many factors; tires, LSD/no LSD, road condition, type of clutch, etc.

My new goal is to become the tire-chirp'in-king. I'm going to get some low performance 100k tires, remove my LSD, and get a 3 puck race clutch. Watch me chirp the tires going into 5th gear!

I'm not directing this commentary toward you Bob, so don't take it personally.

 

ya'll are crazy, crack is way better than anything automotive....

 

I have heard many people comment that air flow at the headlights is very poor. You will get better air flow into your intake tube if you mount it elsewhere.

 

I don't think that qualifies as "cold air".

I had asked around, but that same night i covered the hole. and took it for a spin. there is still a difference

i agree that there is not as much air going in, as one would think. But it is still better than the comptech ice box tube.

the only downside I could think of is that the air could actually be going out of the headlight at high speeds.
when time is more present I plan on using some air pressure meters and seeing how speed effects air movement in that area

i have seen a lot of drag and road race cars with the headlight removed for cold air intake. They would not do it if it didnt produce power

regarding the celsius degrees. i was wrong, I am in the usa not canada.

i understand you are not directing it as me, I was just showing in my case where no other variables changed regarding tires,lsd, clutch. I was able to chirp gears.
unfortunetly that is all I have for factual stuff.

i hear that a lot too. i think ppl are jsut trying to make an arugment out of something. it may not be the BEST place to get air flow, but you can't deny that there is still air flow.
