I've been looking around and I see multiple rules for roll cages. The drag strip I frequent has no rules for roll cages so you can run as fast as you want with no real safety equipment (pretty stupid but most cars run the right safety equipment for their speed). When do I need to put a roll cage in a car? I've seen 11.8 for some tracks. 12.00 for others. Then we have those factory cars that run faster than that with nothing. So if I decided to make my 67 a fast car, whats the lowest ET I need a cage?

Hardtops=11.49 and faster. Convertibles=12.99 and faster.

Also, I believe as your speed increases the points needed in the cage increases as well. Oh and don't forget to have it done by an NHRA certified welder. You can't install it yourself and call it good, it won't pass.

Reason for some tracks requiring saftey and some not, is because if the track is NHRA sanctioned they have to go by NHRA rules.

nhra rules are a little diffrent from ihra

let's see...I can make 11.50 passes all day long in a Mustang welded by folks in San Jose Ca who smoked dope on their lunch breaks, but an 11.49 needs a certified welder to attach a cage....hmmm.
anyone else ever seen a soda blasted 60's Mustang and its spot welds, or lack thereof?

I have had a couple dozen roll cages certified for NHRA competition, and no where does it say that I have to be an NHRA certified welder, all the rules say is that the roll cage has to be certified for competition by inspecting the welds as well as tubing diameter and wall thickness. Any competent welder can have the welds certified as long as it is done by MIG or TIG.

Well, my mistake then. That was my understanding a few years ago when we had our cage put in. *shrug*

Got to draw the line somewhere. If you run 8.60 you aren't required to have a helmet, at 8.59 you are. How much is your head worth.

The only stipulation that I know of on the welding is that it can't be stick welded. If the chassis inspector certs the welds, there is no restriction who does it.

I use a helmet, 3" five point belts and a jacket. I run 7.80's (1/8 mile) so only the helmet is required. Overkill? I almost got to test it Saturday - a 6.60 roadster climbed the wall behind me and then crossed into my lane, I crossed the 330' mark about .3 ahead of him, he crossed right after that. I never saw him, scared my wife to death. If my ancient Z-Gate shifter had done it's usual 2-3 screwup he might have clipped me square in the back.

You may be slow as Xmas, but that doesn't help in bracket racing when you might have a 5.50 dragster coming in though the trunk.

PS - bikes. Those dudes are nuts. We had a guy lay one down in the lights at 130 MPH last year. Ground 5" off the pegs on one side, lighty bounced off a concrete baracade while sliding to a stop. Luckly Mark hit more on his head than anything, in 4 hours he had escaped from the trama center and was back at the track eating BBQ and beer.

I agree, but how does that support rule makers.
