Wont you lose HP.
Just a Question if I may. Wont Short Ram Intake's make you lose Hp. Think about it. In our stock TC's we have a Tube running down through the fender wall where there is little hot air consumption, which is supposed to allow Cold Air to come through. But if you install a Short Ram Intake you defeat that purpose. It is closer to the Intake Manifold, Headers and hot Engine which to me means youll be sucking in hotter Air. So wont you be wasting money by purchasing a Short Ram Intake... Personally I think Short Ram is a waste of money. My opinion. Correct me if I'm wrong.
Well you may be taking in warmer air (dumb for performance) but you're also removing some of the restriction that airflow would face... so you'd be allowing more into the engine, even if it is warm.
In my head, that means you'd see a slight improvement... but your basic logic is right that it's kind of pointless for power in place of a CAI.
But this will be debated forever... Some people don't want a CAI (hydrolocking?) some people want the look of the short ram in the engine bay... some people will get the short ram and then a cold air box to help keep some of the engine bay heat away from the filter...
There's a lot of things to consider.

The big difference between SRI and CAI is the SRI will actually lose some low-end torque over stock. This is shown in the Weapon-R dynos.
But the loss isn't that much, and both will lose power to heat soak. Either version will give you some HP gain, looks, & sound.
And, like any I/H/E mod, you won't see the full potential of reduced flow restriction without adding engine management (E-manage, Camcon, etc.) and a good tune.
The ECU always has the final say.

The SRI will only heat soak while the car is idling or travelling slowly. While driving quickly (probably >15 mph), air is constantly flowing from outside the engine compartment to inside, quickly flooding the bay with "cold" air, making a SRI and a CAI about the same.

cai's don't heat soak either. after a 125 mile drive down the interstate at speeds over 70 mph, when i arrived, i opened the hood, touched the cai tubing, and it was pretty much the same as the ambient air temp to the touch.
for every 10 degrees you cool the incoming air going into an engine, you get 1% more power. as stated by gale banks.
with an sri, you are able to pull in a greater volume of air so your ecu can add more fuel, but with a cai, you pull in more air that is also cooler than the air in the engine compartment.
now, a cai can be heat soaked if the car has been sitting or idling in the sun for a while, but once the car has been driven, it would be cooled off by the air flow going through it.

you don't have to take off the bumper when installing a cai....go through the driver side wheel well, take off the splash guard there......few clips, and some bolts.....what the major concern is when installing a cai, is not scratching it when putting the downpipe through.....either way, any intake nets you almost nothing that you would feel or use....get something cheap that looks good, as they all virtually sound the same

ok i still have that crappy plastic part that is right behind my bumper that protects part of the engine from like water/rocks and what not still on there. is that actually restricting airflow to my CAI? or is that more of a protector from water getting in it? because i have a full CAI but still have that fear of it sucking up water and filling my engine.

You folks saying heat soak isn't an issue should borrow someone's Scanguage and see what happens to intake air temp on just a short stop on a hot day. I have watched my IAT climb to as high as 119 degrees at a red light on a 93 degree day. Figure the power loss from that when the light finally goes green.
And IAT does not drop instantaneously on launch. Usually takes several minutes before IAT drops down to ambient.
Unlike dyno runs, there's no biga$$ floor fan blowing on your intake when you're on the street on a hot day.
Don't get me wrong - I like my Injen CAI - but my next intake will be DIY, probably with Spectre parts, something like Dr. Isotope's GFI.

This is what I did.
Instead of purchasing a SRI which to me is a complete waste of money and I know you lose something somewhere and instead of spending all that money on a CAI. I just took my stock intake, punched out that white filter that was glued into the upper portion of the airbox, removed the other air filter and put in a K&N High Flow filter, then I took the resonator off the piping and put a cap in there and clamped it off. And I bet someone with SRI or CAI will not have any advantage over me or any Significant HP gains over me. And I spent bout 45 bux for the filter. I guess its all personal preference and opinion.

I have a injen cai.....not short ram but the full intake.....I was also worried about hydrolocking.....a few weeks ago I was on I 84 and it was raining soooo hard the interstate was starting to flood so I was getting all kinds of water underneath my car. I was soooo paranoid that I was going to hydrolock.....but no problems at all....and I was running through huge puddles of water doing about 45 to 50 mph......so after going through that my fears of hydrolocking have pretty much gone away.

On an avg. hot day here with my driving style in my a/t at say 110 degrees heat out here, my IAT will be 110-110degrees while driving above say 50mph. Anything slower and heat builds up in the eng. bay a little and heat soaking comes into play. Now...say I stop at a light, those numbers start jumping up like crazy. I sat at a light for about 3mins the other day and my IAT was at 167degrees I **** you not. That's the highest I've seen it so far but that is rather scary I've only seen it register the IAT about a degree or two colder than outside air temp gauge on the HVAC like 2-3 times so far in the month that I'ved had it.

Yeah I hit a personal best yesterday - 123 degrees in the drive-thru @ BK. But I don't live in the desert either.
Where you're at I think you need to do something, after a certain temperature - can't remember when - an IAT too hot can do some damage. You may want to consider putting your stocker back on for the hottest months.
Some people have had success wrapping their CAI pipes with header wraps. Tried that but didn't work for me, couldn't cover all the metal, may try again later.
They do make these insulating sleeves that you wrap around the pipes and close with velcro - might look into that.

Yep
Thanks guys for the input. This is why i've decided to stick with the stock setup and just put in a K&N drop in filter and just modify the stock piping a lil... To many worries if you go SHORT RAM or if you go CAI. For what maybe 3-5 HP at the very most. The noise is not worth a blown engine. Im glad to see there are actually intellectual people here in Scionlife. LOL
