OH CHUTE! TIMING BLOCK SNAFU LEADS TO SECOND ROUND PS RACE REVERSAL | Competition Plus

Bob Brockmeyer, inventor of the Compulink Timing System, the official timing system of the NHRA, thought he'd seen it all until Sunday. Apparently, according to Brockmeyer, the parachute of a Pro Stock car nudged one of the timing blocks yet kept the system close enough that it didn't trip the...

Thought this was interesting.....

yeah, this was pretty crazy...I've seen how this system alarms when a block is out of alignment. I'm pretty sure that it only monitors the timing clocks not the speed, so this makes sense. Its been a while, so maybe Mike English can chime in.

Do they use laser beams? If so, 1/4 inch can through the whole system out of whack.

the system knows if the timing beam is broken or not, and will/can be setup to produce an audible alert in the tower (again, its been 10+ years, so this may have changed). There is a 'light tree' that shows all of the increments down the track and if the light is off, that increment is in trouble (block is out of alignment)

So now are we talking about a software glitch?

I wouldn't call it a software glitch...it was a physical issue with the detection devices.

Like I said, the system knows when the 60, 330, 660, 1000, 1320 blocks are misaligned...but the speed blocks don't seem to be monitored

The block rolled 90 degrees on it's side. The two finish line sensors "Saw" each other so the alarm didn't go off. When the first car went through it stopped both clocks and the timing system picked the winner by milliseconds. the second car across got a bogus high mph because the mph clock was started when it should, but stopped by the lead car.

If you see a picture or the video the finish line block should be at the leading edge of the yellow line, and it 's not, it has rolled on it's side. The other tell is that the finish line block has dual reflectors as a redundancy. They look like a snowman. When you see the block, the "Snowman" is sideways.

...and leave it to Alan to say "hold my beer" and explain it perfectly. Almost like the guy knows a thing or two

Great, Now Alan is bringing in Gene Snow into the show.
