Short Rem intake? better?

i know this is kinda noob question, but you think short rem will give me better low-end?
i have CAI currently. but its auto, so it lacks pretty bad at the low-end.
And what is the HP difference between CAI and sr?

If you can get cold air to a Short Ram, IMO that will get you more torque on any end, low or high. You can get a Short Ram and get the CO2 air chiller Intake system and put that on the end of your Short Ram. You will not be able to use the CO2 constantly for daily driving, but for drag racing or autocross this setup should give you the most gains of any Intake. BTW, CO2 is much cheaper than N20, nitrous oxide. Here is the link for the CO2 air chiller system:

You'll have to buy 1) The Tank and Installation kit, and 2) the Cryogenic Air Intake with the right Intake pipe diameter.

both CAI's and Short Ram Intakes will give you a slight decrease in initial torque. replacing a CAI with s Short Ram will not really make a difference.

to answer your 2nd question..CAI's usually give about 1-2 more whp. this is IF that's all you have on your car. adding more exhaust components (such as an exhaust or header) will increase this gap by a few more hp. synergy thumbsup

Autos are just gonna be slow off the line no matter what you do. Autos cant be launched like a manual can. Short Ram wont give you any better gains.

I have an auto with an AEM CAI. I would say that switching to a Short Ram will not be worth it. I have noticed with my CAI that if i let my car start up for a couple minutes my car runs with a lot more pickup and its ever since i got my CAI.

I heard that Short Ram is not worth getting... the gains are very minimal.. if anything only CAI is beneficial! thumbsup

i like my shortram... evenn thoug hthe gains are slight, it still sounds nice thumbsup
plus it likes to snow and rain a bit here so i know i would get screwed by a CAI sucking up water.

theoretically, a Short Ram will give you more power at top end, CAI will give more gains down low.

The same principle applies to Intake runners, the longer the runner length, the lower in the power band the gains will be noticable.

This is why most import drag cars run Intake manifolds with short runners, to place the maximum gains at the top end, where the engine makes the most power.

The problem is heat, with a Short Ram, you need to worry about hot air being drawn in from under the Hood, which is an easily corrected problem. Simply use heat shields or a cold-air box of some sort to duct cold air from outside the engine bay to the filter. adding an insulating wrap of some sort to the Intake tubing will also keep the Intake charge cool.

I am in the process of fabricating a cool panel/airbox to replace the plastic over the radiator support that will do this, I currently have an aluminum filter heatshield in place. it does alright, but the filter top still sucks in hot air, and the factory plastic above the radiator doesn't help to route in the cooler air.

If you remove the plastic piece above the radiator, cool air from the front grille will be routed towards the Intake, especially at speeds above 35 MPH. just pop the 3 plastic clips that hold it down, remove it, and reinstall the clip that is shared between the passenger side plastic & the radiator piece (without the radiator plasic of course).

Take the car for a spin like that, then after the cruise, pop the Hood and feel the shortram Intake, it will be MUCH cooler. you will probably notice the car seems to pull a bit better too. This is because there are spaces that air can flow from through the front grille opening, to the inside-front of the engine bay when it's removed, especially if you have the action package or another aftermarket bumper.

My cool plate idea will more efficiently route the cool air to the filter, and act as a heat shield (keeping heat from the radiator, engine and tranny away from the filter) it should also keep the filter free of moisture in heavy rain (not that that's a major problem to begin with).

another idea is to set up a RAM AIR configuration: route a lenght of flexible hose (like dryer ducting) to the filter. it's best if you use an open top filter that can accept a cold air duct. there are many that can do this. the other end of the duct goes to the front of the car, much like a CAI, with the opening going to a fog light opening or the front grille. at highway speeds, cool outside air is forced into the filter, cooling the Intake charge, and is much less likeley to hydrolock like a CAI (because there is a natural pressure drop at the filter if water gets sucked in, the filter draws from the surface area with less restriction, under the Hood) this works quite well if it's done right.
