Halltech's KillerB is good, and easy to install. Probably a bigger percent has these units, with the Vararam next.

 

I use the Mr. Fusion and I easily pull an extra 40hp! Just kidding of course!

The CAI question seems common and it all comes down to opinion. You'll see the same names (Airraid, HallTech, Blackwing, Vararam, etc) throughout the threads, but I highly doubt you'll see a huge difference between any of them. <-- That too is just my opinion so take it for what it's worth.

 

I have had two CAI's on my 08 LS3 coupe. The first was a BPP Vortex which I replaced last year with a Vararam. I installed the Vararam based on advice from a local tuner who races and swears by the Vararam. Frankly I can't feel any difference on the street between the two. Since a dyno will not show any of the claimed increase that comes from a true ram air system the only way to truly test is a comparison of 1/4 mile drag strip times.

The BPP was a cleaner easier install.

 

I calculated 624 cfm if you are using 12 cfm per square inch. Some use 15 as the calculated air flow for square inch and then it would be 780cfm.
At 624 cfm ( I like to use the low side) the box will support 898.56 HP. Now don't take that as nothing will increase HP because the box will support that. It means that the stock airbox is not a restriction below that number, but you can still make power with a properly designed airbox. You have to understand that the engine is pulling the air, if the box is designed properly we can almost force feed air into the engine and therefore make more power. For example the Mamba has 144.62 square inches of filter which will support 1735.44 cfm using 12 and 2169.3cfm using 15.That low number will support 2499 hp before it becomes a restriction on the engine. In basic terms of what we are doing is we are ramping the air down inside of the box which is increasing the velocity of the air and therefore flowing more air into the engine without the engine having to "suck" the air in and making more HP because of this. More complicated than how I explained it, but it is the same principle behind some of the CAI's out there, not all of them but only a couple we are just doing the same thing in a different way. It works very well, but at the same time the stock box is not a restriction on the Z06 or LS3 like some claim it is. Now you can help produce more power by getting air into the engine easier which is what the aftermarket filters can also help with.

 

Just research the fast list and you will see the highest % of fastest cars have the vararam. statistics based on real world facts don't lie, i did a stock to vararam comparison the DA was within 10 ft and i picked up .50 in et and 5 mph with the vararam & spacer in the 1/4 mile, i now have ran 10.16 with H&C and vararam and guess what, the guy who beat me with a 10.15 has a vararam, pretty easy to figure out that it works and is # 1 cai

 

Not everyone is running on the drag strip. That is like saying sunoco is faster than shell gas when there is a sunoco station where everyone is filling up at. You also have different drivers, you could be racing a car in the next lane with 1200 HP and a toilet sized air box but he can't drive, you beat him, doesn't mean you have the fastest car, it means you were the faster driver at that point.

 

What spacer are you referring to?

 

you might be a smart man but your analogy is stupid. that's like saying any intake including the stock one is better because more cars have iti have nothing to gain in stating the product works, i don't get paid from or make any money from promoting vararam and the fast list backs it up, i am giving my experience and opinion on what cai will produce the best 1/4 times, if you dont race! it will give the best red light to red light power and even the fastest passing times. put your favorite cai on a c6 race it and see if it can top a fast list, shell and sunoco are both 93 anyone can drive my car its an automatic and if they are less then 293lbs they should go fasterthis argument has been going on for years and will continue, but its really ridiculous if the vararam is on top the fast list

 

when vararam was first introduced to the c6 their was a throttle body spacer, most couldn't install correctly, then they made it with steel sleeves so you couldn't over tighten it, i used it up until i got the fast 90 because it wouldn't fit because the 90 puts the tb further toward the front. it worked great with the C6 LS2

 

Not being stupid, but the point was there are other variables at play than a CAI. Look at the statement above in how they actually work. I am not doubting that a Vararam works, I have seen some that don't. I was only answering based of what you said, by looking at the fast list it is the best. My point is the fastest cars may not even be on the Corvette Forum fast list. I know what my box does in testing, not just dyno number but actual air flow numbers. Again, though it was not the point and it was not to compare my box against any other box, it was just to point out the flaw in saying this is the number 1 cai because it is on the top of the fast list. Yes, you got my point about the gas, they are both 93, but that is like saying one is faster than the other.
Looking at the LS7 fast time we would have been right there. We were a 10.61 with an airbox and DR's back in 06 when we were doing our testing.

 

mumbo jumbo, this is the c6 performance section not the zo6 performance section, Gary 2004 zo6 is a friend of mine and i know the killer bee works great on his car with the addition of vette air, so in your new analogy not everyone has there times on the fast list so i guess even the fastest had a vararam and didnt post it if your box is so great and im not saying it isn't, then what better place is there to post about and enter the times then on a corvette forum to generate sales

 

BEST is subjective. Careful, open filters can cause surging and check engine lights and you will have to tune them out, adding to the expense. if you modify your factory box you can gain almost as much without causing problems.

 

This is what I've been told as well so when I'm ready, most likely it will be modding the factory setup and saving some money.

 

I have a modified into a CAI "OEM" air filter assembly using the stock paper air filter.

If you look at the Grand Sport bolt-on category you will see that I am #1 at present; you will also see #2 has all the same bolt-ons (but better quality) and he has a professional tune, not a "canned" tune like myself and also a NPP exhaust to boot. I am not "sure" but I believe #2 is using the vararam!

#2 is over 4 tenths and 3 mph slower in the 1/4 mile. GO FIGURE.

OH, and by the way I picked up 3 tenths with "just" the OEM cold air modification from my (record setting) best stock 1/4 mile time and the car still runs fine.

 

im not trying to rain on your parade, but the fact that your 60 ft was 1.7s and his 1.9s and your - 1300 da vs his +1100 could have easily made the difference, let alone your great 30.6s BP MIR's famous track prephad a lot more to do with it then your homemade cai, just imagine how much faster you would be with the vararam

 

For two reasons, one I am not "giving" a box away just so someone can go run it in the 1/4 and post it on the forum. Second if you look at my car I don't think it would do to well at the drag strip, now if you would like to take a lap around VIR and compare times we can talk.

 

You need a more detailed tutorial.

 

nice cartry a vararam maybe you could go a little fasterso what is your cai box for road racing city driving, so it wont work on 1/4 mile, do you have a box for retail or is this just a test for your own personal car, were did you run to get the 10.61

 

WHAT? My record bolt-on pass was done at Cecil County Dragway (not MIR) and I do not apologize for being able to put down 1.7's 60 ft. times on all four stock runflats.

OH, and I am the only one here that has "ever" cut a perfect .000 reaction time on one of my "new record" posted time slips in the C6 1/4 mile performance section.

Talking of stats: I weigh 260 lbs. (Fat Man) how much does #2 weigh?

 

See my Mirage Headers thread, I think I posted pics of the cold air intake with detail in that thread if that is what your asking.

See page 4 & 5. My record bolt-on time slip is also on page 4.
