Do any of you get away with running mid 10 second passes at the drag strip with out a roll bar? my car is primarily a street car that i take to the track a couple times a year. what are your thoughts about roll bars in street cars. I see there are several newer challengers that are that fast and faster and are not required to have roll bars.

My Street car has had a cage in it for 23 years. I have padding all around the driver. I should always wear my full harness on the street but I don't. Your head contacting a bar in an accident is the biggest concern.
Last but not least, it won't take a lot of 10 second passes to twist the car up. My Barracuda has a bent drivers door from the countless 1.6 60fts it made before I put a cage in it. The car got raced anytime the track was open and it took its toll.

NHRA track here does not care if it's race or street, only how fast it goes.
I know a guy here who runs his street car only a few times a year at the test and tune fun events that goes 11:55 to 11:60 and they told him to put a bar in it anyway or don't come back.
New cars can run without them, but that is not smart, imo. Car goes into multiple rolls and/or gets hit in the roof by the other car and what protection is there in those types of situations? Not enough.

I see there are several newer challengers that are that fast and faster and are not required to have roll bars. "get away with" is purely at the tracks discretion, neither NHRA or IHRA would condone it as it violates their Rules and has potential to effect their liability and insurability (track and sanctioning body). And to answer your question, at my local track I have seen an occasionally on the first never on the second pass. The sanctioning bodies are very concerned with chassis/roll bar with this type of infraction.

Pretty cut and dry.
If your local track allows it, that's on them.
If the results don't match the theory, change the theory.

what are your thoughts about roll bars in street cars. I've put over 100k miles on street cars with roll bar/cage. It's not a big deal to me. Like Clark, I wear a 5 pt harness with a cage, and have it padded where my head might end up. If you want to play at the track, you kind of have to follow the rules. Get used to buying a new harness every other year.

I have to agree with everyone here. Knock on wood never needed to find out how much I needed it but nice to know it's there. Not to hard for my fat old butt to craw across and my wife even rides with me. No swing out bars on mine either.

I had a chrome moly 5 point bar installed in my old pump gas Duster, it ran10.00 a bunch of times and one 9.993 ET at 134.8 MPH at Woodburn, OR at the Mopar race several years ago. I was told at the time slip booth to not race the car again until it had a cage in it. I discuss that with the main tech guy and told him I would make sure it wouldn't run that quick again, I knew how to slow it down by staging a tiny bit deeper. The drivers side door bar curve down to the floor at the front of the stock bucket seat and wasn't a real pain to get in and out of the car like having it go to the floor by the emergency brake like I had on other cars   I did not have a rear seat in that car so the rear support bars hit the rear subframe on the top of the kick up on the rear sub frames

It really depends on the track. One we go to doesn't even perform tech and you hand your tech card out the window to a guy before entering the burnout box. Another does thorough tech and told me not to come back until I had a rollbar after doing a few low 11 second passes.  We have a 6 pt. and it's really not that bad in a street car. I would highly recommend swingout side bars. I do feel much safer with the bar and the 5 pt harness. We are trapping over 130 mph at times, so that gets sketchy with a lap belt.

FWIW my Camaro has had a cage in it since 2000. Never been a concern or issue for me really. Yes its paded and yes if your head hit it without a helmet it would not end well. But we can die taking the trash out too.

Sort of depends on what you consider a "street car".
To me a "street car" would not require a roll bar, and be something with all the seats front and rear that you can put all your friends in and cruse around in.
On the other hand there is the "Street Legal car" which is really a racing class where the car would be "Legal" to drive on the street. The Legality of "Street Legal" varies widely.
I just don't care to have to climb around roll bars (with door bars) and cages, sit in "race seats" with 5-point harnesses, and have to wear sfi spec clothing to drive a "street car".
It is not just the rollbar/cage, but all the other regulations / certs that have to be kept up to date, like belts every 3 years, if you are going to race your "street car" at a track.
If you want to go fast at the track, it is likely better to just build a "race car".

I have a 25.5 funny car cage in my street car. Safety first... However, all of these No E.T, No time, No Prep, pour your own puddle or whatever they call these kind of events in your areas are run whatcha brung with no rules. I know of many 8 second cars with no roll bars. Dumb yes, but they do it.

If you want to go fast at the track, it is likely better to just build a "race car". People get enjoyment from cars in different ways. I really have no desire to own a car that I can't get in and drive wherever I want to go. If that includes running it at a dragstrip across the country, then it might as well be a fast street car, eh? If you're happy having a car that just goes fast, that you can't drive anywhere else but a drag strip, then yeah, you should just build a race car.

I ran mid 10s for a few years w/ no rollbar or anything in my cuda. Tracks down here are very different from other places...basically no tech inspection.
When I built the hemi and aimed for the 9s, I had a 10 point cage put in the car. If they're done right, the cage isn't a big deal at all. Swing out bars are nice.

100% disagree. We all pile in the car and go for ice cream fairly regularly. Hell, me and 4 friends got in the car and left the track to go to breakfast at the little town just down the road because we didn't want to unhitch from the trailer! The chassis shop that built the bar made sure the back seat fit and things like the rollup knobs worked fine. The only compromises I have made with the car is the rollbar and the spool in the rear. I absolutely did NOT want a racecar that gets pulled in and out of the trailer and only runs for a quarter mile at a time! We've put over 7,000 miles on the car since I put this engine together.
