did a search, didn't find any useful info.

basically, i think my cai is a bit too loud at idle. especially when its in park, the hissing is too much for me. what i want to do, is attach the filter at the point where the bypass valve is, in essence making it a short ram.

couple questions before i commit:

1) will this lessen the hissing sound at idle? i had short rams in previous cars, and it was barely noticeable at idle

2) from what i've read, the cai gives about 6-8 real hp. by converting to short ram, i'd be getting what, 3-5 hp instead? not a big deal

3)i know theres no real short rams available for the tl-s, is there a particular reason why?

worst comes to worst, i can reattach the cold air portion for racing, or if this turns out to be a bad idea.

any comments? has anyone done this?

 

OK... in order

1) Yes, it will lessen the sound at idle, however, you will probably have more resonance at VTEC due to the whole intake assembly including the filter sitting in the engine bay. The trade-off is up to you...

2) you will loose about 3-5 HP in theory... my guess is probably around the 3hp mark. Once you're moving air is circulating in the engine bay. Even though it's not as cold as by the bumper, it's cooler then stock... so you should see around 4-5hp increases. Keep in mind that one place you may feel the difference is from a stop. When you're just sitting at idle there's no airflow in the engine bay.. therefore, the short ram will be sucking in warm air until you get moving. You don't have this with a CAI.

3) It's just easier to produce a CAI since it gives more gains. BTW, I believe Weapon-R and AEM make a short ram for our cars.

 

thanks junior. i definitely don't mind more sound at vtec, thats why i got the intake in the first place. my car does have to double as a work vehicle sometimes, so i need it to be stock sounding for normal driving.

i think i'll try it this weekend. i'll post any noticeable differences.

 

no offense to you juniorbean but your absolutly WRONG.....short ram is infact much louder than the cai and not only does it sound louder in vtec it will sound louder overall....for hp gains dont expect too much of a difference....as for short ram aem has been getting too much resonance from the short ram so they dont see it as a good idea to pursue it cus the cai helps to dampen the sounds that the engine makes(resonance)...how do i know? i personally had both the short ram was a custom one.....and i got sick of the noise so i extended it to the cai but still noise.....no way to get around that.....

i'm not worried at all about the hp. my only real concern was the sound at idle.

are you saying that this will be louder at idle?

I don't care if its louder high in the rev band

 

AGEAN,

Living in NJ now that the fall is starting means that you really do not have to worry about the air being to warm as it enters the engine. It is not likely that you would gain all that much by getting air from under the fender.

 

thanks roadman. even worst case 100 degree weather scenario, the diff between cold air and short ram would be like 3-5hp. thats pretty much negligible in my book.

 

No offense taken.. however, you should use the word absolutely sparingly. Especially b/c I'm not wrong.....

I too had both a short-ram and a CAI and the short ram did not really hiss at all... where as the CAI did/does. VTEC is definitely louder as I said. The difference could be that the short ram I had was Carbon Fiber vs. a metal CAI... so maybe the different material produced a different sound?

Anyway... no real wrong or right as obviously different intakes sound differently... so yours may have been louder all around where as mine had less hiss.

Agean - I think you can get the idea with all comments in this topic

 

junior---i think the idea is that i better try it out on my own

i'll let you know how it works out with an aem cai converted to short ram. like i said, its no big deal to switch back, as i'm just going to connect the filter where the bypass valve is, and tilt it down a bit to fit in the opening by the battery.

plus, no more worrying about big puddles

 

my apologies..... just getting to word happy i guess anyways yeah different materials may have played a factor i myself use both plastic and metal and got simuilar results i testes different methods and have found out that the humm/hiss is what the type s engine does internally(not sure of the tl-p but like the accord v6 i know they dont hiss or humm internally so maybe its just a type s thing?*shrugs* anyways just my input along with others......

 

okay okay, im gonna do this mod tomorrow, and maybe i'm just thinking out loud here but...

i was standing around and admiring the car yesterday, and i got to thinking. is the louder noise from the CAI due to the fact that the filter is mounted outside of the engine bay? maybe the reason its louder at idle is that if it was inside the engine bay, it would have the sound dampening materials around it? now, its basically outside and exposed, so there's nothing to dampen the noise?

maybe thats an obvious thought, or am i wrong in assuming this?

 

yah, ok, bad idea. no one try this.

i installed my filter element right after the bend in the tube (where my bypass valve was) and i got the loudest noise ever.
sounded like a really bad humming noise. whoooops.

i guess they made it a cai for a reason.

 

Didn't work, huh??

Oh well, at least you tried it!!

 

yah, have you ever taken the resonator out and ran the stock airbox? it produces a slightly louder humming noise. multiply that by 50 and thats what i had.

definitely not the outcome i was hoping for, and i really have no explanation except really bad harmonics in the tube. but, no biggie, i got to spend a few hours playing with the car and no harm done.

 

This may or may not be helpful, but I had both a short ram and a CAI on my last car, a 2000 Intergra Type R. In short, the short ram was much louder, as if the car wasn't loud enough already. Anyway, hope this helps. BTW, I am looking to get a CAI for my Type S. If you decide to get rid of yours, give me a hollar.
