I have the Comptech Icebox and short ram so in short I've got the whole setup. I noticed a post by SGT and saw a GSR engine bay with just an open filter attached to a stock intake tube. So I figure, I've already got this but haven't tried it yet. Why not today?

I took off the cover for the Icebox so it would breathe easier, and boy did I pick a good day to test. It was about 87 degrees with about 40% humidity, so it was warm.

I played a little with my wife in the car. We both notice an extreme audible difference. It was deeper and louder between 900 RPM and around 3500. Off the line it was sluggish and actually dipped when I shifted from 1st to 2nd. Then it felt like at around 3K RPM that it had better throttle response, a little quicker. It went to 4K and was loud as Hell, at this point any advantages that might have been there were not noticeable. As it went through 5K and up to 5700 and Vtec engagement it was deep and louder. When it opened the big cams it F*ckin Screamed! I mean I kinda gotta say that I liked the sound But, That was all at a definate power loss, and noone can tell me different! All tha way till redline it was a little less powerful and didn't pull as hard to redline and felt like it would stop at the 8400 line.

So a little later today I put the cover back on and back to the quieter system "which I like" and back to the torquier punch off the line and the definate stronger pull from 4K to Vtec and still a stronger pull from Vtec on. I know It's not just me, It Does pull better with a closed CAI. Geez I can't wait till I get some more stuff on and a Vafc and Dyno and tune this B*tch!

I know what I felt so don't even try to Flame me or tell me different.

But if you have Any creative or constructive conversation to add, you're more than welcome to post. I thought of the AEM/CAI again "I had 1 on my 94/Ls," But, I'm not sure and am currently waiting for my header and HF/cat.

Welcome to: CAI better than Short Ram.

One Question though? I know that the ARC designed intake is extremely high flow but it IS hot air, so is that good or will it feel the same as my experience? If so I'll stick with my setup...

A.

 

If Orion posts anything on this topic please disregard it. Why? Here is a thread similar to what you are discussing here:

That says it all . . .

 

Random sidenote... I built an insulated heatshield around my DC Sports underhood intake and ran a dryer duct tube to the grill to flood the intake with cold air. At a recent track event at Summit Point, (10 minutes idling, 25 minutes ripping around a roadcourse, 10 minute cooldown) I borrowed a friend's pyrometer and got some readings...

Radiator side of heatshield- 160 degrees
Filter side of heatshield- 100 degrees
Filter- 92 degrees

This indicates that
A) the heatshield is stopping a lot of heat
B) the dryer duct MUST be doing something for the filter to be colder than the surroundings.

Hmm... 1% increase in power... 68 degree temperature reduction.
roughly 6% increase in power over straight underhood I'd have to think. That works out to be a good 6+ hp. I can't guarantee that's the truth but... it HAS to be doing something.

 

I have done the same thing, but without the heat shield around my intake, I have the ducting going into the hot side of the intake.

I do not notice the lag off the line anymore. i can also feel the intake sucking air from the duct.
