With the Stock airbox in place, and even if it wasn't you are going to build enouigh pressure to make that a true ram air effect, you a defintaly pulling in cooler air than if it was in the fender like a traditinal cold air intake. But definaly big props on the fabrication.

Sliminem

thanks for the help and i'll look into that.

its sp00n JDM BLUE Y0! lol

SMZ GSR

wow, only 1 person said CAI. This design is more of the Icebox setup than ram air if i'm not mistaken.

Mark

I was wrong in saying it was a cai, huh

What I want to know is, does anyone have any DATALOGGED or RECORDED IAT readings before and after this tube is attached?

Everyone says they felt something or didnt feel anything...Id like to see specifically the drops, if any, in IATs when routing cold air to the filter.

it can't be all that big of a gain.....

a true ram air setup will gain you 1psi of boost @ 100mph. odds are with your setup, you aren't even seeing a 1 psi increase....and 1psi is not enough to be called a VERY noticeable gain.

well i drove it before and after the setup and noticed a SIGNIFICANT difference, i think i would know. it is, after all, a car i drive daily.

as was stated before....placebo effect.......

so the butt dyno has now become accurate?

so you're actually attempting to say that someone wouldn't notice a difference in performance in their own car? that's rather laughable, i go from using a resonator to ram-air (cool air no less), and you think there's not a noticeable difference????? LMFAO wow, hopefully autism isn't contagious, or we're in trouble in this post.

i wasn't saying there is NO effect. i am just stating that i HIGHLY doubt you've got this MIND-BLOWING-ALL-CAPS-SIGNIFICANT gain from running your intake through your turn signal.

take it to a REAL dyno instead of using your *** as a judge.

i did find it VERY helpful at the track!!
seemed to keep the dreaded heatsoak to a minimum!!

Yes but i never claimed it was a MIND-BLOWING change, i said it was significant. going from stock to ram-air is quite a change. it is possible to notice a change in your car's performance w/o using a dyno every time you make a mod.

no....you said it was SIGNIFICANT.....as in "i put it in caps because it was such an amazing gain."

like i said before....i'm not saying you gained nothing....but most ram air systems are useless and unnoticeable under 100mph.

Sliminem

well we could go back and forth all day but it's gettin' old. The point is I have noticed a difference, which is what the point is installing the system. I have noticed a significant change, whether or not you believe/can accept/can comprehend is really irrelevant to me.

i do believe you have a gain.....i'll leave it at that.

Reducing IAT is definitely one of the ways to increase intake efficiency. It is however not the only way this "turn signal" system benefits Intake efficiency.
Remember, that <U>our engines are glorified air pumps</U>, more power is a byproduct of increased efficiency.

This "turn signal" modification (completed as I have described earlier in this thread) increases the efficiency of the intake system in three ways.
<U>1)</U> Pressure at the mouth of the intake system is increased.
<U>2)</U> Pressure loss thoughout the lower intake arm is reduced.
<U>3)</U> Temperature of the air charge is reduced.

<U>1)</U> Pressure at the mouth of the intake system is increased.
Because the turn signal is located very near to the (vertical) stagnation point of the nose of integras, it is naturally subject to higher pressures. That is to say, the pressure exerted here (whith the vehicle in forward motion) will be higher than the pressure at the headlighes, and higher than the pressure below the turn signal.

The turn signal is however not located near the horizontal stagnation point at this same height. Implementing a vertical strake (vertical flap at the left edge of the turn signal intake) will further increase pressure in front of the turn signal.

When Slimenim finishes eliminating the remaining "jaggies" from the mouth of the turn signal opening, he will significantly reduce the number of vortexes that enter the intake mouth. (Vortexes act as low pressure areas.)

When Slimenim opens the rear of the turn signal to proportianately match the intake mouth and turn signal mouth, then pressure loss through the turn signal will be eliminated.

The end result is higher pressure at the mouth of the intake opening.


<U>2)</U> Pressure loss thoughout the lower intake arm is reduced.
This is a result of eliminating plastic "leftovers" that protrude throughout the lower intake arm. Each imperfection within the intake arm creates trailing vortexes that contribute to a compounding reduction in pressure. The idea here is to eliminate any pressure drop in the system that feeds the air box. The mouth of the lower intake arm that feeds the air box is also subject to improvement. A few minutes with a dremmel wil yield a larger "radiused" opening that will reduce pressure losses created by it's original "inverted lip" molding. Radiusing the opening at the intake mouth will also increase flow efficiency and reduce pressure losses due to entering turbulence, or vortexes.

The result here is reduced pressure losses feeding the air box.


<U>3)</U> Temperature of the air charge is reduced.
This doesn't really need to be discussed. I'll write anyway jsut so that this item isn't neglected.
After an engine has warmed up to operating temerature, the air within the enginge bay is subject to a temperature increase (via radiant heat). By drawing air from outside the engine bay the intake air charge begins at ambient temperature which is inevitably lower than under-hood temperatures. As is known, cooler air is more dense and thus colder air delivers a more potent charge to the engine. (Increased efficiency = ?? ) Further temperature reduction can be gained from heat shielding with consideration of the heat sourced from the TB.

End result is lower Intake Air Temperature.


For data on the performace benefits from these improvements in efficiency, buy a retroactive subscription to autospeed.com. They have made extensive use of pressure sensors and switches in testing the intake systems of a number of their vehicles.

I don't mean to preach or step on anyone's toes, but <U>this guy has begun a good mod for his vehicle and all he gets is criticism</U>.

* A side note *:
He has even made sure to leave the gap between the turn signal and the intake mouth. This shows he understood and is gaurding agains the threat of water ingestion from the turn signal. There are still improvements to be made in that area though. . . .

Hey Sliminem,

You can order 6"x6" sample sheets of plastic from this place for like $2.00!
http://mcmaster.com

You get to choose the plastic by it's charcteristics. So if you can find the plastic that is machinable, and weather resistant, and that you can glue/plasti-weld; then you'll be set. 6"x6" is more than enough to make the strake you need!

mugenracer

slightly off-topic, but does anyone have any idea on how much or little air gets past the turn signal when its complete (Not cut like Sliminem's) I know mine aloows some air past it, but i was just trying to figure is it anything worthwhile or does my CAI take all its air from below?

Rory Breaker

Intake temps are really my main concern...I see your point about the pressure, and unfortunately I have to take your word for it since I am no physicist, nor am I really too understanding of the effects

If the routing of cold air to the intake makes a significant difference in IAT, then I would perform it. Otherwise, I wouldnt bother.

People arent so much criticising as they are showing their skepticism, thats all. And for the record, lets ALL agree that the butt dyno means absolutely nothing. A modification such as an AEM may make a significant increase in torque @ 3000-4000RPM, which would definitely make a car feel faster, and it may lose significant power everywhere else, which would still lead the butt dyno to feel that instant rush in the midrange and assume, hey, this thing makes a lot of power!

Butt dynos mean absolutely nothing man. An IAT reading and dyno to show any differences throughout the powerband would be ideal.
