DaddyBuiltRacing Posted December 28, 2011 Report Share Posted December 28, 2011 I have been reading about the NHRA rules today regarding roll cages and found this, just want to see if this is legit or what.. "The NHRA requires a roll bar in every convertible that is 13.49 seconds or quicker in the quarter mile. For cars that are not convertible, their cut-off time is 11.49 seconds in the quarter mile. There is an exception to this rule. If the vehicle has the stock firewall and floorboard intact, it can run the quarter mile in as little as 10 seconds. The roll bar has to be constructed with 1 3/4-inch mild steel tubing with a wall thickness of 0.118 inch. Or 1 3/4 chrome-moly tubing with a wall thickness of 0.083 can be used." This is the first I have ever seen of this "exception", I was always under the impression that no matter what, you needed a cage after 11.49 et's. What is the actual rule about this? If this is not true does anyone know the breakdown of ET/Trap Speed to # of point cage needed? I.E what point cage is needed when going say 9.99 to 10.50's << just an example Also are there any limitations on bending the bar that runs behind the front seats? I am 6'6 and do not want to lose all comfort while driving the car, if bending the bar around my seat position is allowable I would be more open to the idea of having a cage in the car.

hpfiend Posted December 28, 2011 Report Share Posted December 28, 2011 verrry interesting... +1 I would like to know as well... I am imagining they added this so that your c6 z06 or zr1 could run without a roll cage. Quote Link to comment Share on other sites More sharing options...

I am imagining they added this so that your c6 z06 or zr1 could run without a roll cage. Yeah that has always been something that interested me as there are cars from the factory that run faster then 11.49 with no cages. This page is telling me that you need a 5-6 point cage in order to go 10 flat.... http://www.crankshaftcoalition.com/wiki/NHRA-legal_Roll_Bar "extend in height at least 3" above the driver's helmet with driver in normal driving position " Haha that isn't happening at all Quote Link to comment Share on other sites More sharing options...
gillbot Posted December 28, 2011 Report Share Posted December 28, 2011 I was wondering if they were ever going to add an exception like this. Wonder if they finally did. Quote Link to comment Share on other sites More sharing options...
clone Posted December 28, 2011 Report Share Posted December 28, 2011 This is from the 2011 rule book from roll cage section. If anybody wants a copy of 2011 rule book PM me your email and I will send it to you. 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.

DaddyBuiltRacing Posted December 28, 2011 Author Report Share Posted December 28, 2011 (edited) Ok I got a picture with some arrows for you now lol. The red arrows are the bars I am wondering about if they need to be at a certain angle. The blue arrow is the bar I am trying to see if I can bend around my seat http://i126.photobucket.com/albums/p81/alittlelessordinary/rollbar3.gif Edited December 28, 2011 by DaddyBuiltRacing Quote Link to comment Share on other sites More sharing options...
evil8 Posted December 29, 2011 Report Share Posted December 29, 2011 You can run down to 10.00 with a roll bar as long as the stock floorpan and firewall are unmodified. Cage is not required until 9.99. Quote Link to comment Share on other sites More sharing options...
DaddyBuiltRacing Posted December 29, 2011 Author Report Share Posted December 29, 2011 The picture I posted above is what they consider a "roll bar", that looks like a cage to me lol. When I think of a roll bar, I envision an upside down U in the back up a pickup truck, not something with a cross bar, 2 bars going to the rear and a side bar damnit lol.

Patterson Posted December 29, 2011 Report Share Posted December 29, 2011 Cage has a Halo. Bars do not. But you needn't worry about such trivial things... Quote Link to comment Share on other sites More sharing options...
DaddyBuiltRacing Posted December 29, 2011 Author Report Share Posted December 29, 2011 Haha I must worry about these things, I dont want booted. A local guy went 10.90 with no cage and was fine, my luck I'd go 11.49 without one and get ousted haha Quote Link to comment Share on other sites More sharing options...

You have to remember that besides saftey, this will change how your car reacts. I know for f-body stuff Wolf makes a few different style of roll bars and cages depnding on what you want. See if there are any local shops that do more of the import stuff and what they can tell you. Quote Link to comment Share on other sites More sharing options...

Darth_Emma Posted December 30, 2011 Report Share Posted December 30, 2011 I have a cage-related question. Where do you folks go to have a cage installed? I will need to have a cage installed this spring after IPS is done working on it. Quote Link to comment Share on other sites More sharing options...

Darth_Emma Posted January 4, 2012 Report Share Posted January 4, 2012 And to answer your question I would talk with Atomic Fusion on here (he has his car at IPS) and see where he took his car. Yeah, I talked to the guys at IPS and to Atomic Fusion. They use Holt. I just wanted to see if there were other options as well. Sounds like Holt is the place to go in central Ohio. Thank you.

willyp20 Posted January 4, 2012 Report Share Posted January 4, 2012 And Holt does build some fantastic cages. A few of our race cars around here have holt cages in them. Let me do some digging I might have another name for you. Quote Link to comment Share on other sites More sharing options...
