Interesting new Rule coming in 2014

A couple yeas back, I was running a Modified car in Time Trials at the US Nationals and his collector came off in the traps. I was 133 mph,he was 150 plus. He was 6-8 car lengths ahead of me and his collector spit out from under his drivers door area. It was spiraling and coming strait at me. I was just hoping it did not start going end for end and go through my windshield. I ran over it with both right side tires and after the run I looked under the car. It had put huge dent in the frame, and right beside the dent,was the braided fuel lines.Missed them by less than a 1/2 inch.He spent all day at a local muffler shop trying to repair the flatted and twisted collector so he could continue to race.

I hope NHRA is not talking about the old style bolt on collector extensions that use the 3-bolt flange. I would think three 3/8" bolts with a 1/4" thick flange would be sufficient.

My collectors end at my transmission cross member, so I drilled a hole through the cross member and the collector, installed a grade 8 bolt double nutted. I check my nuts before each run (hum that doesn't sound right!). I wonder if that will pass tech next year.

Shouldn't be a problem,, just make sure you tell the tech person, that you check
your nuts before every run! I know,,, I just had to do it!
