Tether Update
from NHRA
Just a quick update to the collector tether rule…. • All racers will need to purchase an NHRA-accepted unit or weld the collector to suffice the rule. • Only those mass producing tether units will be allowed to submit said unit for approval to get on the NHRA-accepted list. • At least one, possible two companies will be posting contingency for their collector tether product. Any questions, contact NHRA Tech. Rock.. |
Re: Tether Update
CBS,
Just my opinion, and a quote from another post. Damn Bob ! ........ easy there ! ......... Jok, its the principle ...... How do I get NHRA approval/acceptance on my vinyl lettering , so racers "Have to buy from me !!!!! My son and I can build complete race cars ...... but we can't make a freeking teather ! Give me a break ! Happy Thanksgiving Im not against some sort of teather/retainer devise as I've seen it happen and a friend got hurt pretty bad ....... I just don't like how NHRA is handling it . They could set a guideline where a racer could make their own .... and then allow the techs be the judge............. Thanks Rock ! |

Re: Tether Update
I understand the rule but don't. Guys like myself who do regular maintenance and check things over between races have to take up for those who don't and buy the tethers. My dragster headers have mounting tabs on all for primaries where the collector bolts up w/ stainless hardware w/ nylon inserted lock nuts. The parts to make these kits are 10-20 bucks if that and the companies are making 1000% on the mark up.

Re: Tether Update
Mark Lelchook's new approved tethers are by far the simplest solution. No sense ranting any more...it's done.

Re: Tether Update
I find it interesting that the Performance Welding ones are no more than what most of us already have. A wedled tab with a nut and bolt. Only difference being they use a wire rope between the mounting points. Dont understand how it is any better than what 99.9% of us already have....Just saying Mark is a good guy and makes great stuff for sure, just find this design a bit curious.

Re: Tether Update
I thought the whole idea of the tether was to have a foolproof system that would not degrade over time like broken welds/bolts on the tabs that most of us already have on our collectors. Now they are approving welded tabs that any of us can weld on to our headers. I thought I understood the purpose of the rule but now I'm a little fuzzy.

Ricki, I'm like you this makes no sense to me . To add more tabs ???
The BEST thing I have seen to date was a fellow racer posted on DDR was a picture of his headers on his dragster. What he had done was to install one button head bolt into each of the tubes with a nut on the inside ....... therefore the collector can be changed or what ever.... Just short of welding , I can't see any more of a positive way to secure...... If one loses a collector with this, he's got bigger problems To add, this guy had the headers/collectors polished or chromed and the the buttons heads blend in and looked great The most positive way ....... for less than 10 bucks ......... Give me a break ! Rick |

That being said,do you sell just the approved "cable" or do you just sell the whole kit as one? |

Re: Tether Update
With my headers having a 3 bolt flange that's welded on and my extensions with a 3 bolt flange that's welded on and these are bolted together do I need the tether ?
I would think that 3 --3/8" bolts would be plenty strong enough to keep the extension on !!! |
Re: Tether Update
you most definately DO NOT want to use a Nylock nut in ANY high temperature application--- the nylon is going to melt!!!!!!! If you need to use a lock nut you can use what is known as an "all metal lock nut"--- these come in several different styles but they do the same thing---
You better check with NHRA on that bolt together collector extension set up get a final ruling just to be safe!!! |
Re: Tether Update
For $59 it's hard to complain too much. Btw, these use pinch nuts instead of a nylock. Contingency paid on these as well.

I did not see anything on their website about contingency. I sent them a question about it. Dan |
Re: Tether Update
Just got an email from Andy Nicholson at Collector-Cable.com. They do NOT pay contingency. They do have a great product.

Re: Tether Update
With all this tether talk even I am confused lol. Just a tidbit from the past...Jok @ collector-cable was against the idea initially. Only when it became clear that the tethers were going to be mandatory did he begin offering them to the racers at a much reduced price compared to others being marketed. http://classracer.com/classforum/sho...t=49067&page=9
