My 01 w/ only Blackwing filter Dynoed 328 / 343.
My friend's 01 Z06 dynoed 360/360 with only the filter.
Put your $400 toward headers.

Got a good gain on my 02.Think the IceBox is a great idea though, cold air does increase HP. With just a cutout I can see how surging could happen.

Nor does the Corvette C5 Special Edition that came out from the factory a few years back with the Blackwing installed.
Well, there's your answer. The cutout causes the surging. The Blackwing was never intended to be a dirty air filter.

I covered the cutout with a piece of plastic and the surging quit, so I made an enclosure. I didn't know about the Ice Box and my sponsor was going to have these units made from my prototype. My sponsor is no longer a sponsor and then I found out about the Ice Box so I purchased one.
The PCM will detect the airflow from the cutout and it requires about 50 miles driving to reset the fuel trims. I have no relationship with the guy that makes these things and in my opinion it's the only way to go.
Hope this helps you. I don't know if it will make your car faster but it made mine more consistent. I think this spring I will install the stock unit and see if I lose any ET. Good luck and Happy New Year to all.

Ok, as a C5 "newbie" I'm getting more and more confused, and I almost want to say to hell with it, and keep the stock air intake!!!
However, what should I get, excluding the Vararam?(do NOT wnat it)
My car is a weekend toy, no drag racing, I'm gonna try my hand at autocross, and I drive "spirited"-ly!! Also, I'm 100% stock right now ('00 FRC)

If I was doing it over again, I would go with one of the filters that offered cold air into the motor. Dave68's mod with any of the bigger air filters would be a good increase from what you have.
As I have the Blackwing now, I'm probably gonna try Daves mod and see how it works. If I get surging, I'll get an Icebox. Simple as that.
I don't know your budget, but if you wipe with 50's, go for the Callaway Honker.

Doesn't get any clearer than that -- the Blackwing drawing engine compartment air causes surging.
Since you're gone,
hopefully someone else will be able to explain what I'm having trouble comprehending......

You really can't go wrong with most of the intakes I listed earlier; it's just that the BEST way to go is with one that draws in cold air. However, a good alternative is cutting the fog light covers and installing Z06 screens. I prefer the blacked-out look (at least for now) and chose to bring cold air in from the lower radiator cover. This has worked very well for me and many others - no surging whatsoever.

I answered in another thread related to the Blakwing, I just copy the post below as a follow up from my own experience:
My first Intake mod on the ZO6 was the Blackwing, improvement over the OEM air box, no doubt.
I was having sometime surging when cruising, and I decide to find a solution through the MAF, always keeping in mind that there is a Tiger Shark front end on the ZO6.
Nothing positive was found around the MAF.
A part of the solution was to close partially the main screen in the Tiger Shark front fascia, having for results to increase the temp under the hood and also the air intake temp.
I decided to go for an "Air Cold Intake" or ACI that is more a “Enclosed Air Filter Intake” , the “cold air” in the best case is the outside air temp, an item that is using the cut in the shroud of the radiator.
NO MORE SURGING...
It came as a conclusion that the Blackwing was grabbing sometime cold air from the opening in the front fascia and sometime hot air from under the hood, which was causing the VCM to change his setting quickly and the relearn time was too short.
At this time I was not satisfied by my IAT, more than 14°F of variation, depending of the speed (HPTuner monitored).
I decided to go back to the BLACKWING plus the ICEBOX, combining a high flow filter with an enclosed air box with a big air volume, always through the shroud, and I added the conceptualpolymer.com mod.
This combo is working really well, surging is totally gone and my IAT are more consistent now, in a range of 5°F, and less speed related.
I am satisfied of the Blackwing IceBox combo and see no reason to go back to another CAI.

BPP Vortex Rammer for me... been great for almost 3 years... no desire the change it. The clear box looks great and I can see how the filter is looking. Also, the filter is a "velocity stack" type which in theory allows straight air flow. My first mod was to peel the free advertising sticker off of it. This is from their site.
