Here are my answers:
1. I did the mod last Sunday and drove that way for about 250 miles before I went to the track.
2. My car is completely stock except for tints.
3. I did the mod just as you showed it on the first post, so it's confirmed, I used a vacuum cap.
As I said I thought my car was faster. When I went to the track 2 months ago the air temp was about 86F, so this last Wednesday I was expecting better times because of this mod, and also because air temp was 66F. Two months ago I was runing 8.6@85MPH in the 1/8 mile, and you can imagine my surprise when this week my best run out of the first 6 passes was 8.7@84MPH. I wondered if the mod had something to do with being slower when I should be faster (at least because of the cooler night), so I removed the cap and connected the hose back. I had another pass right away and bam! 8.47@86.5MPH. The following 5 passes were similar. This experience showed me that the mod doesn't help performance-wise.

20 degree difference in air temp.......good for intake air, bad for tire grip. The warmer day will have a hotter track and give better grip. Too many variables. I don't know if the mod works, but a more controlled environment is needed for testing.

I believe this mod give improved low end torque. I say this because that's what it feels like to me. With the colder track, and the higher torque down low (once again, just an assumption), you get a tiny bit more wheel spin resulting in a lower ETA and MPH. Now in the stock setup, you have less torque down low and therefore less wheel spin...Darshana S...

I think what Stick is trying to say is that the colder track makes traction a issue where the warmer track traction wasn't too big of a concern.

I look forward to trying it. I just need to find a vacuum cap first.
I really like the sound of the second intake. It is usually hard to reach to over 3,600 to get it to roar.
I think it's worth it to try it even if there's no HP gain. The sound alone is worth it.
