halltech or cai?

[SonnyakaPig]

I was supposedly the second L99 with the Halltech Yellow Jacket. It is an incredible unit. I mean, it works like a champ. I'm considering a supercharger next (not a Maggie), and the one thing that I know I would miss is my Halltech.

The sound it makes with my Corsa exhaust is just plain mean and it really made my car faster by the feel of things.

When I only had the Corsa exhaust my car was very quiet. Now, with the Halltech my car is really loud, but like a perfect loud sound -- kind of deep and throaty.

The heat shield does not fit great on my car. Whatever, though, I'm not getting into that.

Also, the Halltech doesn't come with any significant instructions. And yes, Jim will take like 75% of your calls to try to help you. But I really wanted to know how far the velocity stack is supposed to fit inside of the large air cone filter and Jim couldn't explain that to me. He told me that the velocity stack should push all the way inside of the filter.

As a result I was initially running the unit with my velocity stack pushed all the way inside of the filter and it was of course loose because the metal hose clamp that secures around the neck of the filter was not staying tight and it was sliding off.

Finally, a friend showed me that the velocity stack goes into the neck of the filter just enough to sit almost directly flush underneath the circumfrence of the neck of the filter. The plastic filter neck will envelope the plastic velocity stack. I hope this information proves useful for future Yellow Jacket owners.

Now that my filter neck fits right on top of the velocity stack and is tight on top of it, my car runs amazing. Actually, it ran fine when the filter was loose too. haha It's a durable unit.

Technology being what it is, ONStar sent me my monthly diagnostic check and told me that the air induction side of the test was running perfectly, so obviously Halltech put in some serious work to make sure their unit works perfectly with these cars.

All in all, I would recommend the Halltech unit to anyone that is looking for high quality, excellent sound, and increased performance. Seriously, you won't believe it. You're just going to say, "wow," and shake your head when you put it on.

The fitting is poor, it keeps falling off the TB for some reason, the heat shield just doesn't fit right, there's a really big gap at the bottom. Its almost like I got a ****ed up CAI because the fitting all together is bad. Other than that, its not that bad of a CAI, I like the idea of the funnel, and how wide it is. But ADM and Fastlane don't have any of these issues.

I have had had none of these issues either. Why haven't you contacted Jim to get it corrected? Maybe it is just installer error.

There is a small lip at the end of velocity stack. It just seemed obvious to me that the filter stopped there. Sorry you had problems with yours but i'm glad you got it worked out and are enjoying the benefits.

i have the ls3, so out of the two of them, which one has the least problems with sensors going off. i just want to install with no tune and no problems. they do seem to be the top 2. also, what about the adm street one. seems to be a good one too.

I have the CAI induction and the install was easy. I was very pleased with the fit and finish of it as well. I dont have any numbers but I can say there is a noticable increase in power, the exhaust sounds a little better (still have stock exhaust), and it did not throw any codes and seems to run great without getting a tune.

Just an FYI, I bought my CAI from Ted at Jannetty Racing....seems to be a good group or guys overthere and Ted has been putting out a lot of good researched info on the Camaro's. Exhaust shootouts, Cold air intake shootouts, etc.

Same here... CAI, Inc on an L99. Good fit, easy install, no tune needed, and it looks good. Theres a noticeable difference in sound and acceleration.

Very happy with the unit.

I just put on my Halltech yesterday. No codes thrown....car runs great!

[caper]

well i just installed mine the other day, i went with the CAI one. i got it from
SRT10KLLR - who had a pretty darn good price and no wait.

install was quick, might have taken me 20-30min. fit was good (getting the lid on took a little time, seems to be somewhat finicky). overall impressions...i am not sure. car runs well (but it did before too), sound - not sure i can hear much a difference - BUT i already have no mufflers, no resonators and an xpipe, so its prob too loud to hear the intake. under WOT and the upper revs it seems to have a nice howl to the exhaust sound that may not have been there before. no codes thrown at all.

its been dyno proven to work so i am sure it does something, but my butt dyno doesnt register little improvements in a car this quick already. in my opinion, its made a great car a little bit better.

imagine as soon as i start this thread i get my PM from vararam... the odds

I have the L99. I have the Halltech and I my car has shown no codes. And what's more, my car has had two diagnostic scans run by the BF Goodrich OnStar program. They told me my car is showing perfect everything. So, the Halltech isn't affecting anything negatively at all.

I had them check my car because I was hearing a weired noise under my car, sounded like something was loose with the exhaust, so I just wanted to make sure, everything looked good in the computer.

I've said it before but I'll say it again, the Halltech makes such a difference that the need to put it on a dyno is just a technicality (and I will do it, because I'm curious like that) but honestly, the Halltech feels like a mini-supercharger, a very very mini supercharger, but if you get one, you'll know what I'm talking about.

I've read a lot of other people's reviews on many other CAI units, but I just haven't heard people be totally blown away like I have felt with the Halltech, and truthfully, I don't understand how just changing the intake and gaining allegedly 14 rwhp can make that big of a difference, but to me, it really made a huge difference.

My car is so much more responsive now. I feel the power more in the low end and it just screams when the rpm go up, but low end is where it seems to be at with the Halltech.

Saying you can't go wrong with the Halltech is a big understatement.

More food for thought.

What seems obvious to one person sometimes isn't to another. But that's life, right?

Anyway, it's all good now. Thanks for the comment. I'm happy you're enjoying your Halltech too.

[Tmedlin]

any dyno charts comparing the Halltech, the vararam, and/or the ADM race?

[camarohead]

yea thx sonny. sounds like you cant go wrong with either one. about to get the solo exhaust so have to save up for the intake. great information from everybody om these two intakes. just soaking it all in until i am ready to purchase one.
