According to the 2013 NHRA rulebook Quote:
Super Pro, Pro, Sportsman
PARACHUTE
Mandatory on any car that runs 150 mph or faster. See GeneralRegulations 4:8.
Quote:
4:8 PARACHUTES
If outlined in Class Requirements, it is mandatory to have a braking parachute produced by a recognized drag racing parachute manufacturer. Dual parachutes required for all cars running 200 mph or more. Tech inspectors may observe the proper operation of the parachute and inspect for worn or frayed shroud lines, ripped or dirty canopies, and worn or ragged pilot chutes. Parachute cable housings should be mounted solidly to frame tube or other suitable member no farther back than 1 inch. The release housing must be attached within 12 inches of the parachute pack and in a manner that will allow the inner cable to release the parachute. When supercharged or using nitromethane as a fuel, it is mandatory that the parachute pack and unpacked shroud lines be protected with fire-resistant material from the mounting point to the pack. Parachutes must have their own independent mounting with sleeved 3/8-inch minimum steel bolts or steel pins required for all applications unless otherwise stated in Class Requirements. Shroud-line(s) mounting brackets must be constructed of minimum .090-inch steel unless otherwise stated in Class Requirements. Safety pins must be red flagged and removed prior to burnout. The use of ball-lock pins for parachute mounting prohibited. See Class Requirements regarding use of two parachutes. Such applications require separate shroud-line mounting points for each parachute system.
