You don't loose any hp. from installing the intake. . it just depends on what kinda of intake you have i guess and how prop. it's installed Honda-Tech Member

I was just messing around the other day and decided to take off the cover of the diy icebox. It was louder, but it seemed like the throttle response was better and the shifting was smoother (automatic Junior Member

Like you, I also have my aem CAI "rigged as a short ram intake." My reason for doing that was because of all the problems the CAI has caused me (cannot exclude to mention my motor almost blowing due to little amounts of ingested water If you ask why I still did it (rig my CAI to become a short ram), I do not have any front fender linings Anyways---omekone, how did you rig yours? I hacksawed mine to my desired point then filed the edges so the tiny little metal hacksawed particles wont get sucked into my engine. I still used the air filter it came with *I just cleaned it with the K&N air filter cleaner kit (best $10.00 I ever invested). Do you have any pics of your rigged CAI as a short ram? And for those who prefer fashion over function---BTW---which includes the sounds an intake makes cheers NRG In-N-Out Burger

cheers short ram will give you more torque and beter throttle response than a CAI, because its a shorter distance to the IM. CAI , while not adding as much torque, will give you more power, because it is getting cold air, instead of hot engine air. Your best bet......short ram with a hood scoop Honda-Tech Member

If you look at two dynos compairing same diameter intakes, one being short ram the other being CAI... The only difference is the AEM hump of power from 4 - 5k rpm on the CAI. This is all because of volumetric effeciency. The short ram on the other hand, the air velocity is lower. So it takes longer to reach volumetric effeciency. Which is why you see high reving heavy NA motors running Short ram intakes. They need the short ram to produce volumetric effeciency higher in the RPM range so it occurs durring their powerband.

Join Date: Nov 2001 Location: out shooting Posts: 2,800 Likes: 0 Received 0 Likes on 0 Posts omg... here we go. ever look at a type r manifold compared to a b20? really you have? then obviously you know that big fat and short is better for high rpm ranges... noticed the b20s are skinny but extremely long? they provide great torque...use that knowledge to think about intakes. now...the OPTIMUM setup would be a ram effect (colder air...like the cai) on a short ram intake (for high end horsepower), but its all how you want your car to perform. you be the judge.

the only significant difference being the AEM hump in the midrange: This is off of a B-series motor using a single runner IM. Only difference was the addition of the 3" CAI (versus the old setup of a 3" SRI). Notice that in the higher rpms they perform very similar. You'll see the short ram intakes start to outperform the CAI after 8,000 rpms. Honda-Tech Member

Join Date: Dec 2001 Location: N O, V A, U S A Posts: 2,639 Likes: 0 Received 0 Likes on 0 Posts yea, i don't think a dyno can really tell you the HP you are gaining or losing by switching to a short ram, b/c once the car is moving the underhood temps are changed alot from the car just redlining on a dyno. Even the fan can't create the underhood temps you would have if you were driving at 40mph w/ a short ram intake. I say just get a nice filter like the apexi filter and prop it up on short piping and call it a day Honda-Tech Member iTrader: (2)
Join Date: Aug 2002 Location: Margaritaville, AZ, US Posts: 3,235 Likes: 0 Received 0 Likes on 0 Posts The power curve resultant of the intake has to do with the piping diameter and length of the intake pipe....not the "ram air" effect on the street/track being better greater or less with a certain type of intake.
Join Date: May 2003 Location: East Corinth, VT, USA Posts: 155 Likes: 0 Received 0 Likes on 0 Posts In my experiences with my short ram intake, it started off with good midrange pull, but as soon as the engine got up to operating temp, I feel like it lost a lot of power. And i really don't think that too much air actually gets into the engine bay while goin at interstate speeds. Quite often i would get home from
work, goin an average speed of 60 and i could barely hold my hand on the piping ot the intake cause it was so hot. I got inspired not to long ago and built my own cold air intake using my 3" ram air tube, and some flexpipe. Now i notice that it has the same effect on the butt dyno as the short ram did, but now after the engine heats up, it still has loads of power and throttle responce. I drove it for a while the other day, let the engine warm up, and then grabbed hold of the piping and i
couldn't belive how cool it was. It was amazing. Member
Join Date: Nov 2000 Location: Bay Area, CA Posts: 1,132 Likes: 0 Received 0 Likes on 0 Posts depends on many many factors in general, if your motor is built, you better get short ram if your motor is stock, i'd stick with cai
Join Date: Sep 2002 Location: Central Maine area, ME, USA Posts: 2,958 Likes: 0 Received 0 Likes on 0 Posts I switched to a CAI intake a few weeks ago and I am thinking about switching back to my Short ram because I don't want the risk of water anymore. Plus I also have a fully built engine and my Cams will be here on wednesday so the short ram will actually benefit me because ill be raising my redline. Junior Member
Join Date: Aug 2003 Posts: 943 Likes: 0 Received 0 Likes on 0 Posts WRONG..... On a hot day (especially if it is humid) you will lose some power since you are suckin in hot air, remember cold air is more dense... u know the rest. All you have to do is re-route some cold air to the filter and your set! I recomend short ram or the icebox/mugen setup.
Join Date: Apr 2003 Location: 562 Kali, usa Posts: 2,258 Likes: 0 Received 0 Likes on 0 Posts i just switched from a ls cold air intake to an stock air box with stock arm and no resonator to a type r short ram....outta all of them im feelin the type r short ram 3 inch diameter...i feel alot better throttle response and gains in 1st 2nd and 3rd gear i have a 99 ls btw Member

You can't generalize that short ram will always make more power. On my stock gsr, when i switched from cai to short ram, power was lost in ALL rpms Will short ram intake increase horsepower?Cold air intakes and short ram intakes both have the same goal, which is to increase horsepower. But they go about it in different ways. Short ram intakes (SRI) look to increase power by reducing the amount of restriction on the intake air.
How much HP does a ram air intake add?Cold Air Intakes are said to improve your vehicle's performance by 5-20 horsepower. This number will vary depending on the make and model of your vehicle. While this isn't enough power to put you back in your seat, it will give your car or truck a little pep in its step.
Is a short ram intake better?A short ram is less expensive, easier to install, and sometimes creates less power. Some people prefer the looks of the short ram intake. Some people also like that the short ram intake is typically louder when you're heavy on the throttle.
What are the cons of a short ram intake?The most vital disadvantage with short ram intakes is the possibility of heat soak due to being in close proximity to the engine. Short ram intake pipes heat up to a point where the air entering the engine is hot and less dense.
