Air intake system




Halltech TRAP with cold air option: This design can bring cold air in through a “Tunnelport” cutout (where the license plate would reside) that provides the shortest ram-type air path to an air filter, compared to all the rest. Its Warhead filter can only be described as "Massive". Not the easiest thing to install and I believe these are being discontinued.
Vararam: Brings cold air in through the fog light panel area to a panel-type filter. Downside: Eliminates engine bay-cooling air that would've come in from the fog light panels (Z06 or coupe/vert with opened-up panels), so the engine bay may end up being toastier, especially if you add headers later.
Vortech Rammer: Brings cold air up from in front of the radiator and into an enclosed box. Its filter is quite a bit smaller than the Halltech Warhead or Blackwing unit.
Callaway intake system: This one relocates the MAF so that it is just in front of the throttlebody. It directs cold air from underneath and costs more than $400.
K&N FIPK: This is more of a semi-cold air system, as the cold air intake opening is more of a slit. However, it is configured similarly to the Halltech Stinger-R and is 50-states legal. $350
Warm air systems: (Easy installation)
Halltech Stinger-R: Not only contains the massive Warhead filter, but also includes a larger-than-stock airbridge and smooth throttlebody coupler. For $239.00 or less, this system represents the best bang for the buck. Fortunately, for about $40, you can add cold air induction. See my procedure at http://www.conceptualpolymer.com/corvette_c5_corner.htm
Blackwing: Includes just a large filter, but an excellent one at that. Its cost is close to that of the Stinger.
Volant Twin Cone: This system gives you more open filter surface area than any stock box does and is well suited to an engine bay that gets cold air in from the fog light panels, as the filters are more or less in the air flow path.
Zip-tie: An easy and inexpensive mod (eliminates the OEM box’s upper lid), but its sealing ability is questionable at best.
How good are they? My experience has shown that most will bump up RWHP by at least 10. The advantage of having cold air is that power will not be "dialed down" under normally hot underhood (and intake air) conditions. You could easily lose 10 HP with a warm air system after engine bay temps rise during slow-moving conditions. Cold air prevents this from happening.

If you dyno a blackwing you will lose 7 to 10 RWHP by just closing the hood.
My tuner is finding the best results from the new Callaway Honker. There is an article about the Callaway Honker in the latest edition of Vette magazine and installation and dyno by my tuner MTI Racing. Looks very impressive for HP gains.

I can't believe you missed a chance to slam the vararam!
Take a look at the vette magazine article, it is interesting.
You told me you had a 195 thermostat. How do you get the temp below that ? Looks like you should get that gauge checked.
How are you getting ambient air to your filter?
My .02 worth
If you simply want a large, oversized air filter element, and are not so concerned about performance, then the Blackwing or the Halltech are good choices.
Some who tout the Blackwing over the Vararam point to the "superior" filtering of the Blackwing.
I submit that if you are one who is solely concerned, or overly concerned with "filtering".... then save your money and stick with the stock paper filter . You will be hard pressed to find a better filter than the stock paper one and neither the Blackwing nor the Halltech has been proven to outperform the stock airbox with the paper filter in any back to back track testing.
BTW, and not to be sarcastic, but does Donaldson even still make the Blackwing?

In the mean time, you'ld be better off just using panty hose.

I wonder if its the same guy asking himself why he bought a Blackwing in this thread:
