Hello, installed the Halltech Intake today which was a straight forward job for me, at least. The unit is slightly larger than the OE unit. Filter media is definitely bigger. It took me a few hours to install, as I did other things around the house during the install. I had the AB filter prior to the install. No cell and the car runs smoothly. I will head back to the track this week,
weather permitting, to see if I gain any performance. Here are some pics
Actually that was one thing I noticed about the Halltech Intake......drives smoothly. But it seems like it took a while for the ECU to learn. Car definitely responds differently at the low end. You have a nice setup.
Anyway to conduct a standing-still burn out in the C8? It would definitely help my 60ft. I’m currently at the track with Halltech. Car went faster on 1st pass by a 10th. Lmk if there is a way to burn out in one spot.

Just burnout mode only.
Don't worry about e.t.
trap speed with and without intake as well as your pickup in mph from the 1/8 to the 1/4 will tell you power. Then compare with your maximum air g/s on your logs. E.t. is too impacted by launch.
I am assuming you went 11.30 or better from your 11.48? I don't think the ECU likes a standing burnout and may go into a limp mode. Carl Rios does that at the track but he also informed to be very careful.....the car still has to be moving. Carl Messenger has line lock mechanism for his c8 burnouts.

Yea, I searched and saw his car run 10.20s. His burn out is much better than what I’m able to do. I will continue to do what I know currently. Yes, car went 11.35 @ 120.51. It’s hot!!
thx
In the conditions we have now in Florida I am willing to bet that we are at least 4 tenths slower and 4 mph trap speed off. Matt last week ran his new Z06 at Bradenton Motorsport Florida with a 10.89@125......Brooks with his new z06.at the same track ran 10.48@128 in much better air. It was a track rental which was sticky. Nice run on your part.
So, the results, from adding the HT, are as follows:
7-19-23, my best pass before adding the HT was 11.44et at 120.22mph with a 1.73 60ft, 4.78 330ft, 7.34 1/8et at 95.64mph. DA was 2799.
7-26-23, best pass with HT was 11.35et at 120.51mph with a 1.69 60ft, 4.71 330ft, 7.27 1/8et at 96.01mph. DA was 2609.
Note, the DA was a little better on yesterday but was it worth almost a 10th and improvements in the listed categories... 1/4 gurus please share your thoughts.

As one would expect. Statistically there is no significant difference.
DA 2799
95.64 mph trap 1
120.22 trap speed 2
24.58 mph increase from 1/8 to 1/4
DA 2609
96.01 mph trap 1
120.51 mph trap speed 2
24.50 mph increase from 1/8 to 1/4
Your car was ever so slightly more powerful than the stock run in the first half of the track and ever so slightly less powerful than the stock run in the last half.

You're 60' time helped your 1/4 mile. I have the Halltech too. Not impressed for $800.
C8s are not going to do that much improvement in those kind of conditions even with bolt-ons. That's one reason I am not at the drag strip right now with my Halltech. The only way I know of to be a good comparison is to have a completely bonestock car at the track at the same time against a full bolt-on.
Most bonestock Z51's at our track are not running 120 traps unless there's is really good air. But they are definitely running good ET’S due to better 60ft times.

It's a wash statistically speaking.
My car is not stock. I have headers, catback, ported intake manifold and throttle body. Trapp and et both show power. I believe the HT increased performance in the areas listed, even the 60ft. I was unable to break 1.7s on the 60ft and did so each run (made 3 passes) except for the final pass. I should have noted that I tried a different burn out technique that was a bust on my 2nd and third passes. Car did not leave as good on those passes as it did the first pass. If it were possible to do a good burn out, the car would have a much better 60ft, which impacts et. A few racers commented that they were about 4 tenths off there et and lost mph.

That's exactly what I was trying to convey earlier. Right now with our weather I would be lucky to just get 11.60s. I will definitely report my results with my Halltech next time at the track......good or bad.

Stock run meaning your baseline run.
Again, ignore e.t. on your first run you were at a 1.73 60 foot.
On the halltek run you had a 1.67 60 foot.
Your e.t. improvement was all launch. The first 60 feet. Shifting, traction, launch is e.t. forget about that if you're trying to purely evaluate mods / power.
Like I said...trap speed and back half delta is power.
Your car without the halltek picked up 24.58 mph without the halltek in a worse DA.
Your car picked up 24.50mph in a better DA with the halltek.
If you're looking for objective power data that's it.
If you want a better e.t. throw on a drag slick and you'll run 3 tenths faster but you won't have made more power.
