Just looked up the 2014 NHRA rules, and found this. Looks like roll bar 11-13.5 and a cage under 11's?
ROLL BAR
Roll bar mandatory in all cars (including T-tops) running 11.00 (*7.00) to 11.49 (*7.35), in convertibles running 11.00 (*7.00) to 13.49 (*8.25), and in all dune-buggy-type vehicles running 12.00 (*7.50) seconds and slower. Permitted in all cars. See General Regulations 4:10, 10:6.
ROLL CAGE
Roll cage mandatory in cars running 10.99 (*6.99) or quicker or any car exceeding 135 mph. In full-bodied cars, with unaltered firewall, floor, and body (from firewall rearward, wheeltubs permitted), running between 10.00 (*6.40) and 10.99 (*6.99), roll bar permitted in place of roll cage. In convertibles running 10.99 or quicker or exceeding 135 mph, roll cage mandatory. Cars running between 7.50 (*4.50) and 9.99 (*6.39) must have chassis recertified every three years by NHRA and have a serialized sticker affixed to cage before participation. Plating of chassis prohibited for all cars manufactured after Jan. 1, 2003. Rear- engine dragsters must conform to SFI Spec 2.7B; vehicles running 8.49 (*5.35) to 7.50 (*4.50) and/or exceeding 180 mph must meet appropriate SFI Spec for body used. Effective Jan. 1, 2007, all new Street Roadsters must conform to SFI Spec 10.4. Existing Street Roadsters must meet SFI Spec 10.4 at their next scheduled recertification effective Jan. 1, 2008. No existing cars will be recertified early to delay compliance. All others must conform to specs for body style used, as listed in General Regulations 4:11, 10:6.

Under 11.5 you need a full face helmet and fire jacket.
There is something about cars after 2008. I know the NHRA made some concessions for newer cars in super car territory stock such as the 997.2 tt and Nissan GTR, etc that run in the 10s stock

I'll look into it also as I'm in dangerous territory anyway but I'm almost positive there must be fine print. I was just at the track Weds and was quoted rules from the NHRA about needing a cage <10.0 and >135.

My experience is that you are correct about the new provision/rider in the NHRA rules because cars that run 10's stock are ok, provided they are unmodified (from what I understand). So maybe the 10.4 pass was enough to get you removed since our cars are 10.8 factory.

I'm have that time on stock.
2012 Turbo S on upgraded ECU cobb st1.
10.8 - 10.9 sec 1/4
your exhaust + 100 cells + IPD + ST2 ECU is not work)))

Akunob recorded that last month in August and I'm going to guess that it was very warm with high density altitude, which will significantly hurt performance. I bet if he ran in the late fall with low density altitude he would be able to get in the mid-10's @ 132+

I agree and will add that it was his first time at the track with the car. I know his car and it runs very strong. His mods work.

Could my car run a faster 1/4 mile, possibly, but that's not the point. I didn't go out there to PROVE anything, I just went to have some fun (and get some numbers to share for webcarconnection, I had never done a timed 1/4 mile before). As others have mentioned, hitting optimal track times is a combination of great timing on the launch, sticky tires, correct tire pressures (i.e., much lower than my street setup), lower temp, optimal gas etc.
I'm sorry if my 1/4 mile time didn't meet your expectation, my few bolt-ons work just fine for me (improved throttle response, higher boost, practically no turbo lag, quicker spooling etc). I'm content and got to meet/hang with a fellow 6speeder! Thanks Longboarder and Stage 7, you guys get it!

Akunob's first time at the track hardly represents his car' s end all performance figures. Not only were the conditions horrible, but the track we went to can be daunting to even a seasoned vet. Once he gets used to it, he will net better numbers for sure. Also, at least he contributed some more data points, which is the point of the thread. Criticism is only going to make less people post, which doesn't help anyone.
At this same track, in negative DAs in the fall, I've seen a tts run 11 flat with same exhaust and a plenum (much lower mph).

Thanks Chris/webcarconnection.
To be fair to 1YARD, its possible that he is only making a simple observation, that "on paper" with a tune, 100 cel cat exhaust and plenum HE THINKS my 1/4 mile figure should be quicker than his stock TTS w/ Cobb stg 1 tune. If that was your point 1YARD then you simply forgot to factor in 3 things (1) conditions on the day, (2) the driver and (3) the ECU tunes!
The conditions for your timed run and the conditions for my timed run may have been drastically different, which as others have pointed could affect the recorded times and trap speeds. Second, driver...I bet if Chris drove my car (same day/same conditions) he might have squeezed out 1/10th or 2/10ths of a secs better performance...he is simply a more experienced and better drag-strip driver than I am! Although I'm certain he couldn't replicate his 10.4 secs run in my car...your car is simply a BEAST Chris, (Mitch & co at Cobb would be proud)! I am a "noob" at drag racing! LOL...its possible that you are also a better drag strip driver than me.
Finally 1YARD, you failed to account for the tunes. Your say your car has Cobb's stg 1 and I am running FVD's Lvl 1. Maybe Cobb's stg 1 adds more HP/TQ than FVD's lvl 1! FVD claims +70HP/+89TQ for their lvl 1...maybe Cobb's tune produces more... I don't know. All this shows is that you are probably doing yourself a disservice by DIRECTLY comparing your 1/4 mile figures to mine, given the numerous variables present. The best test will always be side-by-side races...which is why we enjoy Longboarder's videos so much
1YARD, you are a fellow p-car guy, and I suspect like us, you love talking and sharing experiences about the cars, tunes, mods etc...so welcome!

OK, 4 pages and a LOT of views and no numbers from .2's with softronics, EVOMS (one wIth GIAC and one with FVD) C'mon people, this is not a contest
