Re: NHRA 2013 Rules Amendments
 

Think you are right. I remember collector extensions that were slip on but every collector I have had bolted on to 2 primary tubes. I see some stainless ones with spring attachments. Just too many words to say "collector". We know what they are saying but why not just say collector, not multi-piece exhaust collector? But Mr Tech Man, I don't need them because I have a 1 piece collector, not multi-piece. I was an NHRA tech man for years and this is what causes problems. Poorly worded rules or should I say wording open for arguement.
And are these really better-safer. Both do the job if they are secured but neither if they are not. I'm just being picky I guess.

Re: NHRA 2013 Rules Amendments
 

So if your collectors and primary extentions are bolted to the primary tubes, are you still required to have this retention devise?

I remember someone losing a collector on a S/C dragster at the 90 race last year. Who was that? :)

Re: NHRA 2013 Rules Amendments
 

I guess a door car with headers bolted to collector to mufflers bolted to chassis isn't included in this rule. As the bolted in muffler would act as a restraint. But I wouldn't be surprised how NHRA interprets it.

Don't be so sure. It says a removable collector must use an NHRA approved tether. Being bolted in doesn't make it non-removable. Your using logic again.

Re: NHRA 2013 Rules Amendments
 

I have lost one when the tab welds cracked:rolleyes:

Re: NHRA 2013 Rules Amendments
 

That lost collector at the .90 race was off of our car, and it cut the tire. If that matters. But, dont be fooled into thinking it cant happen to you. The rule is a good rule, but I didnt help write it.

I know it happened to Kenny at the .90 Nationals last year and also to Mike Holland on his burnout on his final License Pass on Friday Night at the .90's. They were able to kick it off the track before he backed up over it which would have made for a mess

Re: NHRA 2013 Rules Amendments
 

Hey, I remember that. I think it is a good idea to tether the collector after what happened to me on my license run. I know most everyone goes over their cars with a fine tooth comb, but the collector tabs are something we never think will fail until it happens to us.

Re: NHRA 2013 Rules Amendments
 

Looks like the only way to get around this rule is to WELD the collector to the tubes. So if I was building a new set of headers I would mount them on the car then weld the collector to the tubes before I powder coated them. That way they are not removable and don't need the teather. I have lost a collector on my old door car when the tab cracked. However on my Super comp dragster I have dynatec headers with 4 bolts on each header and they are out in the open where I can check them as I wipe them down after each pass. The old saying out of sight out of mind does seem to fit in some of the door car cases. I don't want to have to put up with the teather, so I guess I will have to weld on my chrome headers. We will see how the rules are applied. Any one else have any thoughts on the subject.:cool:
