Here is a quote from Comp D of me and my basic oppinion of the safety increases for these trucks.
These are minimums, in my mind.
These are minimums, in my mind.
AS I've said before, but not yet in this thread.
I know this thread is concerning 11.5 or faster. But let me throw this out first.
I would personaly have a 5/6 point bar in a 12.5 second truck. However, as far as writing the rules go, I'd vote to implement a 5/6 point bar at 11.99.
Therefore the 12.0 bracket trucks COULD run without one if they so choose. But, I think any truck that can touch 11s should have one.
I'm not even going to address the other safety items in this thread, but cages and bars are a hot subject. So, there ya go.
Now to the topic at hand.
11.5 and faster.
starting at 11.99
5/6 point NHRA legal rollbar
5 Point Harness
Helmet
Fire Jacket
Reverse lockout shifter (if you're shifting your auto tranny)
Driveshaft loops
Tie Rod sleeves or replacements on IFS
There is more but, this should give you the idea.
At 10.99 full cage.
If a truck can dip into the 10s it should have one.

basic 6 point
---AutoMerged DoublePost---
padding/cage foam would be a great solution for this....

All of this is like a broken record. The simple fact is that things are happening today that were not happening 5 years ago. The amount of truck racing has increased by leaps and bounds in the past 2 years. Put that together with specifications that were designed for a 3600 lb car not a >6000 lb truck and what do you have?
Pat can bring up anything but an answer and try to bring in things that are not part of the discussion. Were not talking about 1/2 ton trucks, motorcycles and the rest of his BS. Were trying to discuss vehicles that are over 6000 lbs racing at speeds over 100 mph. What the out come will be who knows but if Pat has his way we all will have no input into it, because he wants to derail all the threads until they are closed or he gets kick off the site then he can claim censorship somewhere else on the Internet. At that point the decisions will be made for us with no input.
Last time I looked there are how many 9 second Full size Duramax trucks?
Answer: 2 both tuned by TTS and both running an array of TTS products
We were the first Full size production Duramax in the 12's,11's, 10's, and 9's
So what if anything has this got to do with a safety discussion..... NOT A DAMN THING!

Fastest street trucks are not TTS anything. Western or Eastern hemisphere.

i've been reading and thinking about this..... i understand where ya'll are saying a 6pt cage on a 3500lb car is safer than a 6pt cage (made from the same material) on a 7500lb truck. let's not reinvent the wheel here let's make it more efficient..... why not increase the STRENGTH rating on the roll bars.
why not rally for a stronger 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 us 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.

Let's see this FULL size truck your all talking about because the only other one in the 9's is tube chassis with a scaled down body call Dirtymax. Any racer knows that would not be a full size truck. I do not need my name on the title to know what we've done nor do our customers. I see your still trying to twist the facts to meet what you want.
Thicker tubing for truck with a cage but at what point do you need to add just a simple roll bar? For the >6000 lb trucks I would think somewhere sooner than a <3600 lb car.

The rules do need to change...the question at hand is, how much ?
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.
