Roll bar questions?????

Nmbr1GMfan · 10-22-2017, 09:26 PM

Well my kid is a shortie and we have a roll bar issue. The rules clearly state that the helmet must be 6" or less from the main hoop, I guess I could move the hoop to the midddle of the door but I'm hoping there's a different solution. Anyone have a similar situation? What's the NHRA's fix going to be?

The 6" is from the back of the helmet to the roll bar not the top.

Absolutely, and we're 12+ inches away. By short I meant the seat is so far forward.

A double hoop would be a fairly simple install. I think a call to your division tech director is in order.

Add a Funny Car cage? It would close the driver in better and provide for better seat bracing with a cross bar.

Looks like it is just a 6 point roll bar not a cage. I would complete the cage if it were me. Also appears the seat is on an adjustable base. push the seat back during tech and move it forward after. Other option would be to move the seat back and extend the pedals so she can reach.

This is not a rule that is heavily enforced, I wouldn't worry too much about it. I think you would have to find a tech guy on a bad day to get bounced over this one. I've built a lot of roll bars and never seen this come up as an issue.

I have never been teched sitting in the vehicle. I would only be concerned if it were a safety issue for the driver.

Obviously there is a safety issue here. The driver's helmet is over 12" from the main hoop. Also for sure the side bar in the car will be too low to match the driver in her forward seat position. I think you should upgrade to a cage. Add a halo and two forward down bars. Modify/change the side bar to suit.

I just went over some things with our roll bar inspector for our area the other day. My question was adding some other bars, he said once the main design or requirements are met, any bar of ones choosing can be added with no size requirement. So with that thinking you could add another top hoop foward of the main one, even down some to get close to her helmet. Run one side down and back to seat bar and the other side down to side bar like a funny car cage. Maybe do another side bar to cross her shoulder-elbow, straight out then turn down at the new hoop intersecting point. Then back down to roll bar at the floor, just like the kidney bar. Seems rather simple to do. From what he told me they can be even 1-1/2 or smaller. As far as safety is concerned he said with a roll bar you actually have two cages, the car structure and the roll bar. What you have passes the tech now, just add what you want.
