why not rally for a stroncer tubing to be used in these trucks? to me it would be simpler and more efficient. we built a roll cage one time in a car using 1 3/4 inch x .144 tubing. all mild steel and it passed NHRA tech many times. didn't cost up more than 100bux to make and worked..... why not look into 1.5x the wall thickness of a larget tube with slightly thicket wall thickness?

if a bridge won't hold XXXXX ammount of weight with 6 contact points why add 4 more made of the same material? why not built it to support the weight from the begining with 6 contact points and larger material?

these are my thoughts as i don't race my truck regularly, it's not "super fast", but have built a few cars that have been VERY fast and lasted a long time and never once was safety an issue.

Exactly...you can also use a Maraging C250 that has the tensile strength of Rockwell C but has a moderate yield point.

You could have small, reasonable changes, like larger, thicker tubing which would be a good thing IMHO...or large, unreasonable changes like caged 12 second trucks...but one way or another, changes are on the horizon.

Why would they change anything if there isn't proof the existing standard is inadequate?

Perhaps you could convince them there is something seriously wrong. Even a small group, if they shout loud enough, and say it's for the "common good" will be listened to.

Heck, you can't have a cigarette on the beach anymore.

What about the fact that the cage rules are written for cars typically half the weight of our trucks?

How about regulations on the stuff that prevent ever having to need a safety cage?

Don't confuse the issue with facts Preston.... :tttt:

BTW nice to see more hot rods here. :U:

Lmmafo (just like LMAFO except with a phrase enhancing M added)

says the man with this avatar....

Ok back to topic, yes it is very serious and can change the sport completely what will come of this.

Can you show me where the NHRA handbook says designs are for "cars only"? Or, "we ignored anything but lightweight sportscars"? It might be true, but if so, it's news to me.

Most of the basics in the handbook come from the 1960's. Cars were neither light, nor safe. Neither were the pickup trucks. Yes, they did have them back then. Not all the cars had seat belts even.

Relatively recently, in lieu of the fact racing was getting safer, they eased up on the minimum requirements, and so far have had good luck.

The #1 safety equipment problem is not the rulebook, it's whether folk follow it.

If we actually follow the existing rulebook, and run the trucks setup in a responsible fashion, we will continue to have good luck. No bias/radial tire mixes. Tube tires get tubes (stiffens the sidewall). Engines tuned correctly for drag racing.

Low CG's will do more to prevent rollover injuries than all the tube steel in the world. No rollovers = no rollover injuries. The Crankshaft Height rule should be enforced.

I like the FAA method. Make sure it's safe before it takes off, rather than skip preflight and give each passenger a parachute instead.
