What exactly is the difference between a short ram intake and a full length intake. Is there anything specs/performance or is it just length? I'm not exactly comfortable with how low most full intakes sit, with all the rain we get around here I'll be running on gas and water instead of gas and air.

To add to that, any suggestions on which is best?

Thanks.

 

umm sri low end, cai top end.

 

Dynos have shown that CAI's perform much better than short ram. For instance, AEM claims their v2 cai gets 20hp on an rsx type s vs the short ram that averages about 5hp. But yeah if you live where there's a lot of water... go with the short ram

 

20 hp from intake on an NA motor? ha! CAI or SHort ram, you'll see between 3-5 hp each. the difference in HP isn't the cold air with the CAI, that really doesnt matter, the difference is in tuning the bends of the tube. Both should see about same MAX HP number gains, but depending on which you get, it will change your HP/Tq curve...

 

20 HP from CAI?!?! That's a bit of an absurd claim from AEM...

I was looking into getting the shortram AEM intake, since AEM seems to be the way for intakes. I'm not expecting much to come out of it, I just don't have the money or time to do a swap right now. Thanks for the info, any other suggestions, my car's in my sig.

Please don't post again....

 

prove me wrong, CAI intakes are designed based on tube length, diameters and bends... once moving, the temps under the hood are quite ambient and the gains in the 5 degree difference are negligable.
the main gain in HP with either is eliminating the pressure differences in the factory airbox.

He said on a RSX type S. I see the Type S gain 15+ from CAI all the time. Whats so funny about that?

Well I have a Napolex digital thermometer that reads outside and inside air temps. I stuck the sensor on my short ram and watched the temps and then I hung it down where it would be on a CAI. Once moving the CAI temps are quite a bit colder...

That and the fact that in almost all the dyno's I've seen the AEM CAI outperforms J's racing intake, and J's intake is supposed to be all about air velocity (piping diameter) to make power.

 

There's no way you're going to get 20HP from a CAI, even on a RSX-S.

 

you did this while stationary, notice I said ONCE MOVING, the temps are nearly ambient. Were not looking to make power at idle...

 

OK well u can go ahead and prove these real dyno tests wrong

 

get a comptech icebox, or a ITR AEM CAI.

have fun.

 

you can do a lot to get dyno numbers in your favor dude...

 

It a known fact that the K20's, for some reason, do see almost 20hp gain from a CAI. You can even do some searching and find some dyno charts that will prove that. Pull your head out of your *** and realize that it is possible, on the K20's, to see those numbers.

 

skrew all that stuff, i felt a bigger hp gain in a sri than a cai. but i started getting pulled over alot so then i just put the stock intank and droped a spoon drop in air filter and felt a better gain then a sri and cai. plus when i get pulled over and they lift my hood it looks all stock. the drop in air filter are cheaper too. but thats just my opinion.

 

Yeah...from what I have read...not saying it's true as I do not own a k20...but the CAI is supposed to see up to 20hp gains...Just saying from what I have read...I am not saying it's true...

agreed, everythign ive read about the rsx and type-s is that its a LOT easier to get higher gains then from any other engine. and i too have see the dyno charts showing the gains from minimal upgrades on the new rsx's

 

search is ur friend!

 

j's racing intake aka the whale ***** is said to give gains in the mid dyno proven

Few things you should ask yourself before purchasing an intake, or taking the advice of he said/she said.
-What is the car going to be used for?
-what type of power is going to be most beneficial to you? Midrange or topend?
-is it a daily driver?

There's so much hype, and misinformation out there, it's mind boggling. No 2 motors are the same, and not everyone is after a big peak hp number. Some want realistic, usable power. For ever person that tells you the CAI is the way to go, there's 2 other people that will tell you the SRI is better. Use the parts that are going to benefit your build.

 

cai is more efficient top end
sri is more efficient low end

please correct me if i am wrong

 

dyno's dont really do a CAI justice, once you get air flowing over them...they get real cold....and the engine bay still gets really hot, even while moving. but thats not the point, either one is better over stock for the noise factor and air flow diffrences

 

I have a Injen SRI on mine, and my car seems to actually lag a little bit. It sits almost right over the transmission.

you got it backwards, the longer tube length(cai) is better for low end power and torque production while the short ram generally has better top end breathing characteristics
