Last week...
Spoke with Jim Hall on the phone once and via email about 3 times. He answered all of my emails the same day they were sent. Great to do business with.

Thursday...
Ordered the Stinger and cold air package.

Friday...
Received Stinger (had it overnighted).
Installed it in 20 minutes - this is a no brainer install.
Went for first ride and heard a buzz from the engine room between 3k and 4k rpms. Also, the vehicle was hesitating and surging.
Emailed Jim.
Took the vehicle out and put about 27 miles on it. By the time I returned, the buzz was gone and the drive was smooth. I was pleased with how much I could feel the difference. I really wasn't expecting to feel as much as I did. My 3rd gear really seems to like the new set up. This is not a placebo effect, this is real throttle response and push into seat.

Now the big surprise...
Picked up my 9 yr old from school. He doesn't know I did anything to the vette. After we get out of the school zone, I tap it a little, nothing outrageous, just a strong acceleration. My son looks and me and says, "what did you do?". I said, "nothing why?" He said, "the vette feels different like faster." Coincidence...maybe. I still tell him nothing is different and we go for a little after school ride (this usually precedes his homework time). During this time, he likes to shift while I drive and I let him when it's safe. Anyway, after we do this for a while, he says, "I'm telling you Dad the vette is faster today." I tell him what I did and show him at home.

Temp was actually warmer here friday than the two previous days so if anything the temp conditions were not favorable or the cause of the feeling. I honestly don't think I was driving anymore agressively than normal.

As far as my son goes, I think because he leans up when he shifts and is not supported by the seat back, he is more susceptible to the acceleration forces and has to fight them.

Get home and Jim has responded by saying that he has not heard of any other car buzzing after the install (mine went away) and that the surging was normal as the vehicle was retrimming and needed about 50 miles and one cool down session for the fuel cells to catch up to the new air.

Saturday...
Drove car early in the day and I still would swear there is a noticable difference. Case closed...I'm sold and happy.
Received the fresh air package in the afternoon.
Installed in about an hour.
Haven't had time to drive anywhere yet.

I'm assuming that the package will contribute more at higher speeds since more cold/fresh air will be allowed into the filter area. This could have a twofold effect...cooler air and more air allowed in the area...both would result in more dense air to the intake (a good thing). I went with this solution because I don't think it is anymore susceptible to hydra lock than the stock system.

Anyway, that's my experience. Would I recommend this change to others...yes. Just my opinion based on first hand experience but no dyno numbers.

 

great write up - have you considered a tune?

 

 

I'm just starting to research improving air intake to my C6. I'm curious if you looked at the K&N Intake? http://www.kandn.com/images/l/63-3052.jpg

Was there a particular reason you went with the Halltech?

 

Tj...

I am considering and want to go with a tune. I really want to do Jim Hall's but I don't want to send the ecm in. Long story short, I am leaning toward the Diablo Predator (not out yet).


Dcolemhome...

I went with the Halltech because I felt like it was not at risk for hydralock, AND Jim responded quickly and professionally so I figured I would get good service/support - which I did.

 

There is a way to tune by email. The only problem is you need your own copies of all the software required.

PM for details.

 

Though I'm happy with my Halltech (still have to install the cai), my car showed hardly any SOTP improvement. Even if gained an average of 10rwhp/10rwtq, it would be very difficult to feel that, at least in my experience. Now after my tune, that was an improvement. Maybe not more hp but it has allowed me to use what I've got and maybe the Halltech was part of that.

 

i would have to say that i just got the halltech and i love it...but i would for sure get the tune rather its sending your ecm chip off or just taking it in like to MTI and let them tune it. but if halltech isnt the only thing your going to do to your car i would wait until you get everything done then tune. but by the way what is the Diablo Predator?

 

Do any of you feel there is any concern with the intake cover being removed? The cover that, on the oem setup, helps keep water from the hood front edge getting to the intake system?

I was looking at the Halltech SSM install instructions which implied no more cover.

Is it possible that because the Halltech isn't a flat panel design, and placement, that the water seepage isn't a concern?

Just curious. tx

 

My Vette is my weekend driver so I can avoid driving it in the rain. Not much of a worry for me.

 

Take a look at the video on Jim's site of him spraying water on the filter with the car running.

 

Hmm, I forgot about that. Ed@LPE mentioned that video - but I haven't been able to find it on his website. Regardless, thanks for the reminder.

 

I have the CAI and the Stinger...lots of rain here, plus car washing...no water at all on or near the filter. Mileage is better too !

 

This should answer your question:

I'm impressed!
