So how are we going to tie down all the rocks and pebbles at the strip?

I would guess that the person who thought up this tether BS is the same one that approved those bogus AMC parts.

I would assume you forgot to add the bogus Chevy, Ford and Mopar parts too, and let's not forget the bogus horsepower ratings.

Hey, would Super Stockers or other cars that run a vac-u-pan system need them? They've got a hose holding the collector on.

I did get a very nice email back from NHRA refusing my submission for the tethers submitted last week.
At least they did answer my email and submission.
Below is the email.

Hello Rick,

I am the right person to contact regarding the upcoming 2014 tether regulation.

I understand your concern with the current list of approved header collector tether manufactures, however I would like to indicate that we have recently received several additional submittals from manufactures to accept their tethers for use. Therefore the manufacturers, type, and cost will be changing soon. We cannot accept requests from individuals for one off tethers , due to the number of requests we would receive which would inundate our resources as well as make it very difficult to regulate in the field. If you would like to work with a manufacturer to market your idea, we would be glad to review their request for potential approval. The NHRA Technical Department will also accept a minimum ½” (half inch) stich weld located each primary tube as an alternative to the tethering system.

I hope you understand the reasoning behind our need to only accept Header Collector tethering systems from manufacturers willing to distribute NHRA accepted tethers. Furthermore, please watch www.nhraracer.com for additional accepted tether manufactures.

Now were really grasping at straws lol.. It would probably pull the breather out of grommet in the valve cover if the collector came off, more carnage.

Great that they responded...hopefully they gave Mark Lelchook some formal feedback on the alternative solution he discussed with them at Indy this year. I don't think this whole deal has anything to do subterfuge or under the table dealings, just an Engineering group working with a liability-adverse bunch of bureaucrats and the corresponding absence of common sense approaches. This will hopefully result in a reasonable cost solution. On my chassis car (yea, I know our classes are a different animal) I initially balked at diapers but when I dealt with Diaperman and put his on I quickly recognized I was getting a good value that increased safety.

Is there a possibility the NHRA's insurance company is requesting these after someone hearing of an accident or injury happening somewhere at some track?
I sure do understand if you can weld a roll bar, this would be a piece of cake to make. you guys have shown some nice designs on this thread.

[Bernie Cunningham]

OK, it seems it ain't going away, (can't believe it made it this far, SHRA?) but I have got to get an answer with this question ---- ' if you have an approved tether system and somehow, somewhere, blackhole, planets aligned wrong or whatever and ya **** breaks free and does some damage i.e still hits somebody or something, WILL NHRA take responsibility cause they approved it??

how does that work when **** goes wrong in the oiler classes ? they must have more 'approved parts' then us ???

inquiring minds need to know!

A great question that needs to be answered! They still haven't answered why we can put in our own roll bar and submit them to tech but we are not capable of putting some clamps and cables on our headers and have them teched for approval! I disagree with you Jim Carter, this fact shouts kickback real loud! Jim

" The NHRA Technical Department will also accept a minimum ½” (half inch) stich weld located each primary tube as an alternative to the tethering system."

Don't insult our intelligence with this BS response! Weld my headers onto the car? Only a moron with no knowledge of race cars would suggest this!
