Testing: Cold Air Intake design, not a short ram hot air or enclosed filter setup

Get your stuff on the market, man!! 
10whp for an intake is def. a huge WIN on these cars. The ability to drop temp by more then 10, 20 or even 30 degrees = awesome!
Are you saying I should keep my water/meth kit?
I started reading up on NA Meth kits that run off of maf voltage....Not really seeing a down side to using this unless our ECU completely freaks out under certain loop maps. I :heart: water/meth

You are definitely right about the stop and go traffic and being unable to escape the heat soak. Even the OEM system builds heat significantly in that type of environment.
During the prototyping/testing phase of our intake, our average IATs during constant velocity averaged 5-6 degrees warmer than ambient, which was on par with OEM. The fact that you are showing slightly better intake temps isnt surprising, but probably wont register with much benefit either. You'd need to drop temperature by at least 11 degrees(all other things equal) to even see a less than 1% increase in horsepower output.
I do commend you efforts though! THis is the type of ingenuity and work ethic necessary to advance the aftermarket platform for this very capable engine. Bravo!
We do have some plans drawn up to address this heat soak problem for racing applications. MMMmmmm....a shot of cold air to reduce IATs by 40 degrees sure sounds nice. Doesnt it? And no, it isnt nitrous

yes, I'd keep your meth injection kit. If you could just wire it in under WOT I think that'd be the best use. The ecu is the smartest I've seen. I think it can handle the meth injection just fine.

When my CMGS coolingmist kit arrives I'll be messing with the min/max spray looking to target -4 hg thru -1 hg to spray. I think the sweet spot will be WOT but there should be room to get the most bang for buck having it come on just a bit sooner under load.
Do you think utilizing a larger diameter piping for the intake will help or hinder performance in terms of A/F? I want to lean this thing out a bit w/ the stock ecu..

Honestly, I'm not sure what'll happen if you use a larger diameter pipe without altering the maf signal. Keep in mind that the throttle body will still be the bottleneck and you'll also be reducing the velocity of the air over the maf sensor.
My first guess is it'll throw a too lean code. My second guess is that'll adjust fuel to get it back to stock until it runs out of room....then maybe throw a code.
I'm really not sure.

That low-hanging intake design is susceptible to ingesting water during rain. It doesn't have anything to do with ECU. It's up to the physical design and location of the intake openning.Anyway, I'm sorry if I overlook that you have any system to prevent water from ingesting into the intake during the heavy rain??

I performed this MOD back in 2006 when the car was @ 2 weeks old.
I dont remember much data but I do have some dyno number floating around CL that prove the CAI gained @ 2-3WHP over the short ram type. The power band moved down to @4000 rpm which made the car alot more snappy. And I did lose power up top until I added the Blitz Stainless Filter.
From what I remember my final dyno numbers were
281 WHP
265 WTQ
With my mods being:
Custom CAI with Blitz Stainless mesh
Apexi SAFC
Custom 2.5 inch midpipe to HKS Axle back exhaust
A/F ratio tuned to 14.0 WOT with the Apexi SACF

Yea I think I have performed almost every "ricer mod" to this IS.
I can say it has held up very well.
I have screwed with the motor from day one and it has always liked it.
The pipe I used was a K&N 3.5 inch upper to a Honda Civic/Autozone 3 inch lower.
I could never get the A/F ratio up above 11.5 - 12.0 with just the intake.
You should really try the Apexi SAFC. The power band smooths out so nicely at 14.0 AFR.

Doesn't the ECU just tune the AFC changes back out via O2 feedback after a bit? that's what Gernby found way back, hence why he had to make a more advanced piggyback system to work around it...
Or are you talking just for WOT/track/dyno use, rather than everyday use?
