Sooooo someone in the tower hit the "go to the wall and smoke the tire" button on John Force against Robert Hight, I knew John would not throw a race.

Alan, what can they do if an event like Bruce Allen's out-of-control dieseling ever happens again? Happened 2003 in Joliet I believe....Jim Yates probably remembers it well

The parachute component, from my understanding, is different than the manual cut off which simply cuts the fuel off. I believe that the parachute deployment is triggered by a change in manifold pressure. So in this case it doesn't apply.

I also thought, at one time, they talked about having the chutes automatically deploy if the driver hasn't done so a certain distance past the finish line. Not sure if that was implemented or not.

Edited...found it. The link to the NHRA website is no longer active but here's the summary:
The 2010 season brought a new safety device to Top Fuel classes. Should the driver be rendered unable to perform the normal shutdown sequence at the conclusion of a run, a pair of redundant transmitters, placed 400 feet (120 m) and 600 feet (180 m) past the finish line, will signal an on-board receiver to automatically shut off ignition power and fuel to the engine and deploy the parachutes. The transmitters are designed and placed so as to avoid inadvertent triggering of the automated shutoffs. These transmitters and the receivers that are placed on all cars were designed by NHRA's Track Safety Committee and constructed by Electrimotion, and are a direct result of Kalitta's death.

So I'm not sure where the posts above were going but the parachute "issue" didn't apply to Dixon's scenario.

Yes it does if the safety box was activated like alan said the sytem was the chute should have fallen out!

IMO in this scenario the engine shutdown would do nothing if it is truly dieseling, no ignition required

Nostalgia Top Fuel and Nostalgia Funny Car also have the Leahy device. I believe they were required for the 2011 season.

Not the radio frequency one. Only the burst panel activated one.
